F-100
F-100 is the original North American Airlines (International Aircraft Company has been and 入罗克韦尔) has developed the world's first supersonic jet fighter in level flight capability. Used primarily as fighter-bombers. September 1953 began the armed forces. Main types are: A, C, D, F and so on. Produced a total of over 2350 various types of aircraft, in 1959 all production. Users except the United States, as well as France, Turkey, Denmark and Taiwan. F-100 has been in combat in the Vietnam War bombing mission, the Air Force (USAF) in Vietnam, one of the main models used. Citation

Air Force speed of sound. They will be determined to develop the world's first to exceed the speed of sound in level flight in a practical fighter. February 1949, North American Aviation F-86 Sabre began to study the supersonic fighter variant, engineers 雷蒙德赖斯 and 埃德加舒默 Germany (P-51 Mustang's designers) in the company self-financing support began to study how to make knives to achieve supersonic speed in level flight. The results show that: Just F-86 wing sweep from 35 degrees to 45 degrees can get this ability, but the wind tunnel tests showed that the maximum speed can only increase the sweep angle increased slightly near the speed of sound encountered the sound barrier, or can not be reached supersonic speed in level flight. Facts have obvious improvement only for aerodynamic shape is not enough to achieve the goal of supersonic, but also the need for greater thrust - much larger than before. This General Motors Allison Division presented a way to provide 4,082.57 kg of thrust J35 engine variants, F-86 is almost twice the thrust of the J47. GE also made a modified J47 engines, rated thrust 4,264.02 kg afterburning 5,897.04 kg. September 4, 1949, North American Airlines decided to concentrate all resources in the development of F-86D's improved all-weather interceptor, and to ensure the availability of supersonic performance. Plan modified by General Electric J47 engine, the 10,668 meters in height will be able to reach top speed of Mach 1.03. This However, when presenting the program to the Air Force but was rejected, U.S. Air Force instructed the North American Aviation to design a daytime fighter. After a some modifications, in January 1951, North American Aviation submitted to the U.S. Air Force, This is a daytime high performance fighter aircraft, in many ways with the U.S. Air Force also rejected the proposal, but considered that the design has developed into the potential for air superiority fighter. A program under the North American Airlines called the It combines Estimated at 10,668 meters above the ground can reach Mach 1.3 (1,383.74 km / h) maximum speed. Combat radius of 1,078.03 km, combat weight of 10,773.45 kg ordnance four 20-mm T-130 cannon. North American Airlines asked the U.S. Air Force funded the purchase of two October 1951, although previous researchers have worried that the key to F-86 fighter-based design in daytime would be too complex and expensive, USAF Committee decided to start the This is because as the outbreak of the Korean War, US-Soviet tensions simmering, the Air Force 45, the Commission now only hope that his sword in service as soon as possible to ensure the Air Force's air superiority. To speed up the progress of military service, they decided not to directly verify the prototype through production, This is a high-risk decision-making, drawing on the World War II B-29's production model, the benefits can make a paper airplane is still available to the Air Force as soon as possible, but on the other hand will bear great technical and the cost of risk, because once discovered during the prototype test unexpected problem, we must have been in service and the aircraft is to improve the production line, and bear the resulting long delays. However, taking into account North Korea's intention to contract. November 9, North American Aviation's revisions. November 20, 1951, North American began a hundreds of U.S. fighters. Two prototype models for the YF-100, the company model NA-180, production for the F-100A. April 24, 1953, the first aircraft YF-100A (product number :52 -5754) has finally shipped, and in a highly confidential, the factory moved to Los Angeles from North America, Edwards Air Force Base. North American test pilot George. S. Welch (George S. Welch) on May 25, 1953 his plane made its maiden voyage, and a breakthrough in the flight speed of sound. September 15, 1953 completed the second phase of flight, YF-100A has completed 39 flights, the total number of hours 19 hours 42 minutes. October 14, Chi dazzle flat iron, 1953, the second aircraft YF-100A (product number :52-5755) first flight. F-100A (company Model NA-192) is a super tool with the first production models. First aircraft F-100A (product number :52-5756) in the September 25, 1953 the factory, and in the October 29 flight, test pilot George Welch remains. All this only occurred in the second prototype YF-100A aircraft two weeks after the first flight, super project with knives progress at an alarming rate. The end of November 1953, the first batch of three F-100A began delivery of George Air Force Base, equipped with Tactical Air Command Fighter Group 479 436 daytime daytime Fighter Squadron. Which began its 31 years of service career. [1] The design features of F-100 was first designed as a daytime air superiority fighter, the aircraft using the normal layout, nose into the air, moderate sweep under cantilever monoplane, low, flat tail and single-tail inverted T form type tail layout.
F-100 front close-up
F-100 but with the way the nose into the air, inlet air from the nose into the air intake to lower jaw in order to make room for airborne radar. Although the inlet head of least resistance, but the biggest drawback is that radar can not install the mainframe. This makes the F-100 enhance the combat capability of the future was extremely restricted. Since the aircraft after an American fighter no longer use this inlet. F-100 using conventional Pitot inlet, the nose is not used to adjust the intake shock cone. Thus, when the Sonics formed in the inlet is a great shock resistance, and seriously affect the inlet total pressure recovery. This is the F-100 remained at the maximum speed of only one of the main transonic zone. However, usually the nose into the air and the aircraft is different from the aircraft's air intake is flat round, rather than the usual are circular, which constitutes the unique shape characteristics of the aircraft. As the inlet flat garden, the upper part of the line was under the head tilt, which makes F-100 before the bottom has a good vision for the future develop into a fighter-bombers provide an objective condition. [2] F-100 with a new design of thin airfoil wings, and the relative thickness of only 7%, which greatly reduces the resistance of high-speed flight. Thus, while only 45 degree sweep of its wings (and quite subsonic MiG -17, MiG -19 far less than the contemporaries of 55 ° sweep), but still able to achieve supersonic design goals. To address the cross-plane, supersonic pitch control, F-100 Driving abandon the stabilizer and elevator into one, with a single, full-motion wing instead. F-100 tail design is a tragic chapter in the development process. The aircraft experienced a tail design in a few years from big to small and from small to big process, but this seemingly simple change has led directly to the number of outstanding pilot was killed, and more planes and November 1954 the Air Force issued a comprehensive fleet of F-100 flight ban (lifted in February the following year). As the design years earlier, F-100 does not use This can be seen by the large number of photographs, This will inevitably lead to significant increase in transonic drag. The aircraft can achieve supersonic, mainly due to J57 engine and the relatively small thickness of the wing. Overall, as a 100 There is another unofficial nickname F-100 is the first major structure in the fuselage of the aircraft used titanium alloy, and its main purpose is to avoid the result of aerodynamic heating of supersonic flight, aircraft structural strength reduction due to the design, each with a weight of F-100 titanium alloy 650 lbs. In 1952 to 1954, North American F-100 in order to produce the United States consumes 80% of total production of titanium metal (including 95% in 1953, 1954, the increase of the titanium production fell to 60%) so the cost of the F-100 is also quite expensive at that time, reaching $ 664,000. All models YF-100A
YF-100A at Edwards Air Force Base over the
prototype, only the production of 2. 300 million spent developing the person, the first YF-100A aircraft at April 24, 1953 the factory. Aircraft is equipped with a Pratt & Whitney developed the high-thrust (at the level of terms) XJ57-P-7 Turbo II structure, axial flow turbojet engine. May 25, 1953, the aircraft at Edwards Air Force Base in the first test flight, and succeeded in breaking the sound barrier. [3] F-100A F-100A of the company model is NA-192 is a super tool with the first production models. First aircraft F-100A (52-5756) in the September 25, 1953 the factory, and in the October 29 flight, test pilot is still George. Welch. All this only occurred in the second YF-100A prototype aircraft first flight two weeks after the project is over with knives progress at an alarming rate. F-100A, in most respects similar to YF-100A, but the truncated tail, and after the tail protruding above the installation of a pipeline release. Blueprint in the USAF, F-100A is set to daylight air superiority fighter, and was portrayed as the ideal successor F-86A/E/F saber. F-100A installation of four 20 mm Pontiac (Pontiac) M-39 cannon, 200 rounds each door with a bomb. M-39 has been installed in the F-86F conducted in the Korean War on the actual test, then called the T-160, issued 1,500 per minute rate of fire, muzzle velocity of 1,005.84 m / sec. The end of November 1953, the first batch of three F-100A began to deliver George (George) Air Force Base, equipped with Tactical Air Command Fighter Group 479 436 daytime daytime Fighter Squadron. The Battalion September 29, 1954 with the F-100A operational capacity. Since the self-service F-100A, USAF pilot, has been reported that the existence of their F-100A stability and control problems, the time when the wing drop tanks hanging problem is especially serious. They suspect that this is the tail area is not big enough, not enough to maintain directional stability caused. Result, most of the early F-100A was never flew over the limits of the performance envelope. North America has been reluctant to admit that this is the result of stupid tail design. Disaster finally happened, 12 October 1954, the day George experienced test pilot. Welch driving the first nine production F-100A (52-5764) to conduct a performance test dive limit in a high-G pull After starting, F-100A air disintegration. Welch ejection successful, but was part of a large piece of metal cabin body piercing seriously injured. 8 November, a visit to the Royal Air Force officer Jeffrey. D. Stephenson (Geoffrey D. Stephenson) driving an F-100A, crashed due to loss of control of Elgin (Elgin) Air Force base and died. November 9, Frank. N. Amory (Frank N. Emory) Major driving F-100A (52-5771) shot in Nevada during training over the loss of control crashes, but fortunately Emory safe ejection. November 10, USAF F-100A all ordered grounded, the total is about 70, while there are 108 in the factory super-waiting with knives have delivered fully assembled. Conducted a detailed investigation, all evidence indicates that F-100A is the source of security problems short tail, it is also the USAF pilot has been suspected. So the F-100A of the tail to change the style back to YF-100A, an increase of 27% of that tail area, has been to Mach 1.4 only when the phenomenon of instability, and this speed is the performance of the F-100A outside the envelope. After these changes, F-100A increased to 4.68 m high. RF-100A photographic reconnaissance aircraft. September 1954, six close to the completion of the F-100A was modified from the line out for the unarmed photographic reconnaissance aircraft, model RF-100A, the aircraft's serial number 6, respectively 53-1545 ~ 1548,55 -1551,55-1554. Removed and replaced before the body of the gun five surveillance cameras, the lens towards the front and sides, respectively. The camera system can not fully incorporate it into the fuselage, so had to set protrusion of the drum kits, used to position the windshield extends to the main wing trailing edge, a RF-100A of distinct characteristics. RF-100A can carry four drop tanks instead of two F-100A, because the typical mission profile for a long time need to RF-100A high-speed afterburner flight, and will not have air refueling. Because the protruding bulge, RF-100A was a F-100B-weather combat bombing type. In order to allow space for installation of radar will be moved to the fuselage belly inlet (NA-211 program, there is a program of NA-212 F-100 is the basic layout in use), and improved three-wave system for the wedge-shaped supersonic inlet Road, and then the fuselage will be moved to the back of the inlet, the inlet to form a unique backpack. Half-buried belly fuel tank of a water drop shape. Abolition of the traditional ailerons on the wings, replaced by the spoiler. Horizontal tail is still low, flat tail all acting. Tail has been redesigned, converted to all-action tail, cancel rudder - this design was later applied to the design to the Navy A3J (ie A-5 Because the application had just discovered the development of all-weather fighter-bomber. F-100B which was renamed the YF-107A September 10, 1956, the first YF-107A aircraft first flight. Lost in the competition as F-105, YF-107 quickly dismount, only the production of three prototypes. F-100C F-100C fighter-bomber is a super family with knives in the first truly operational capability of the model, dates back to the YF-100A before the first flight in October 1952, USAF requirements of North American research and development for the super wing tanks with knife , July 1953, USAF has requested a new Finally a new wing in the F-100C's design. U.S. Air Force (USAF) F-100A of the order to change the number of the last 70 bombing of agencies to combat type, model as F-100C, the company model NA-214. 1954 年 2 24, Air Force has updated the 230 F-100C. The fourth aircraft F-100A (serial number 52-5759) was used as the prototype F-100C and to be modified to extend the tip. Since the body has been completed on a facelift, F-100C wing structure bearing increased 6 points, to install removable rack can be mounted, including fuel tanks, napalm, General bombs, airborne high-speed rocket, bomb, bomb load 2,268.09 kg. Another wing structure was strengthened to withstand the local release of weapons brought sudden impact. Containing oil in order to meet the In the final design, cheap chi flat iron, F-100C F-100C with single point pressure refueling port, compared to the gravity refueling F-100A is a great way to progress, installed in the wing, detachable air by tubing to F-100C equipped with air refueling. First production model of the F-100C (53-1709) on October 19, 1954 off the assembly line, because this time all the F-100A are grounded in the tail waiting to solve the problem, so that the aircraft is qualified USAF reception. January 17, 1955, the North American test pilot George. Hoskins (George Hoskins) flew its first flight. It has the F-100A aircraft in early-type short tail, cheap chi straighteners, tail high after the conversion. May 27, 1954, USAF F-100C will be the order total to 564, is more than double the original, but in the September 27 contract was again amended, to the last of 224 F-100D. F-100C starting from April 1955 to deliver the Tactical Air Command. Texas Foster (Foster) Daytime Air Force Base 450 Fighter Squadron became the first unit equipped with F-100C, and in July 14, 1955 have the capability. The end of 1956, F-100C into the Air Force stationed in Japan, Fifth Battalion 8 fighter-bombers in service. The first F-100C in a small number of installed J57-P-7 engine, rated thrust 4,400.10 kg afterburning 6,713.56 kg. Most F-100C (up to 101 aircraft) of the power plant is the J57-P-7 of the improved J57-P-21, -21 type of 4,626.91 kilograms of rated thrust with afterburning 7,257.90 kg, and offers greater at high altitude thrust, the F-100C maximum increase of about 64.36 kilometers per hour, climb to 10,668 meters, time-consuming by 10%. F-100C One of the more serious problems with the F-100A the same: when the high-speed access without control yaw and roll tendencies. From the 146 F-100C began, the introduction of the yaw damper. This improvement seems to help alleviate this problem, we first factory F-100C have carried out this modification. From the 301 F-100C, the pitch damper was added to the horizontal tail control system, which will help attenuation over the longitudinal oscillations with knives. In order to solve the problem J57 engine compressor stall, installed inside the engine valves to avoid gas accumulation phenomenon. August 20, 1955, Horace. A. Hans (Horace A. Hanes) Colonel driving F-100C set a new world speed record. He Mojave (Mojave) desert over the 12,192-meter section of 15-25km altitude routes running back and forth twice, with an average speed of 1,322.82 km, becoming the first supersonic aviation history of World Records, is the first record created in the high altitude , past records are created in low altitude. September 4, 1955, Carlos. Talbott (Carlos Talbott) F-100C Colonel driving across America coast to coast, with an average speed of 982.66 km, with a total length of 3,740.93 km. For this feat, Carlos. Colonel Talbot was awarded the Bendix (Bendix) trophy (Vincent. Bendix (Vincent Bendix) for the flight across the continental United States set up the trophy race). F-100C produced a total of 476, the last one delivered in July 1956. There have been over 150 F-100C deployed in Europe, the main base in Bitburg, Germany (Bitburg), 福斯滕费尔德 Brook (Furstenfeldbruck), Landstuhl Seoul (Landstuhl), and the West Hahn (Hahn) , also deployed in the Morocco and the Netherlands. U.S. Air Force F-100C is also very short service life, quickly replaced by F-100D. Exit after first-line F-100C transferred to the ANG, 1959 first in mid-ANG squadron began equipped F-100C. Air Force F-100C remaining in the late 1950s, mostly for training missions. JF-100C NASA research and test machine. Only one (production serial number :53-1709). TF-100C two-seat trainer prototype, converted from the F-100C, only one (production serial number :54-1966). August 1956, TF-100C first flight. The aircraft performed well in flight test, F-100F two-seat trainer which come out. However, only TF-100C aircraft finally April 9, 1957 crash. F-100D's battle with nuclear bomb type attack. January 24, 1956, F-100D prototype (production number :54-2121) first test flight. When to stop production until Gaixing Ji produced a total of 1274, F-100 accounted for 50% of total output, F-100 is the most important modifications. The machine is actually a modified C-type, North American proposed a total of four improvement program, the company numbers were NA-223, NA-224, NA-235 and NA-245.
single flying F-100D
in appearance, the machine still retains C-6 wing pylons, but the delivery method used to improve the ejection, rather than the original gravity free delivery method. Vertical tail and rudder area is increased, then the square edge of the upper fairing also increased to accommodate the radar warning receiver, antenna and emergency discharge tubing. F-100D improvement is mainly reflected in avionics equipment. The aircraft is equipped with 明尼珀利斯 - Honeywell developed MB-3 automatic pilot, making it the first equipped with supersonic aircraft autopilot. MB-3 greatly reduces the introduction of pilot workload, making the pilot's hands can be freed for access to navigational charts or weapons targeting, and in the MB-3 aircraft under the control continues to the target. However, the system can only be used in stand-alone flight, when the F-100D formation flying, MB-3 is usually closed. Other avionics systems include: AN/APG-30 fire control radar,, AN/AJB-1 AN/AJB-1 low altitude bombing system (LABS, improved, can be used for delivery of nuclear bombs), AN/AAR-4 infrared search system, AN/ALR-45 radar warning receiver, AN/ALE-2 chaff dispenser, as well as navigation and communications equipment. When a nuclear attack, F-100D could carry MK-7, MK-38, MK-43, Mk 28 EX, chi turbo flat iron, Mk 28 RE, TX-43, TX-43 X1, and other types of nuclear bombs (usually left hanging mount point and the fuselage centerline mount point), explosive power from 1000 to 10,000,000 tons TNT equivalent range. Bomb the main mode of a In a typical attack missions, F-100D from a minimum altitude of 900 km / h speed penetration, close to the target to an overload 4G pull up to be a catty fighting, in the process the computer automatically calculate and put a nuclear bomb, the plane arrived backflip vertices to level to do a half roll, and then speed off to escape the damage radius of a nuclear bomb. [4] QF-100D unmanned drone. From the retired F-100D converted from, removed all the ordnance system for air weapons testing. A total of 218 modifications. F-100F two-seat trainer Serial, F-100 final production. The aircraft in March 7th, 1957 first test flight. To stop production in 1959, produced a total of 339. Although the trainer, but the F-100F retains the ability-to-air combat and ground attack capability, but reduced load of bombs, gun is also reduced to two. Later part of the F-100F has been modified specifically to-air missile attacks on positions and artillery fire control system with a radar position, the planes is called QF-100F unmanned drone. Converted from the F-100F unmanned drone. When the last one F-100F two-seat machine after delivery, with knives in the production of super-history come to an end, the total number of super-production with a knife last reached 2,294 aircraft, including 359 Columbus plant. F-100J F-100J program is based in Japan of foreign military assistance to provide all-weather interceptor, but the Japanese government was not interested, and therefore remain in the conceptual stage. F-100K F-100K is the F-100F Dress J57-P-55 models after the engine has never been produced. F-100L F-100L is the F-100D Dress J57-P-55 models after the engine has never been produced. F-100N F-100N is the F-100D of the reduced form, after the installation of a simplified electronic system available to the NATO member, but failed to get orders. F-100S F-100S is the installation of 1964 Rolls - Royce (Rolls-Royce) Company RB.168-25R Spey turbofan engines of the F-100F, chi pink dazzle limited edition, plans to establish production line in France, 200 F -100S, but not realized. Service speed race course a successful maiden flight from the YF-100A, the Air Force in turn use it to create the world speed record flight. Speed record at the time by the Navy's XF4D-1 YF-100A first time and the flight speed record attempt in the traditional sectors on 3 km, although the XF4D-1 does more than speed records, but beyond the range of less than 1%, according to regulations recognized. October 29, 1953 Pite Ai Winster Colonel driving again, the first aircraft attack the YF-100A, in the 15 km leg to create a 755.149 miles / h record, succeeded the throne first hand from the Navy won back. Grounding incident in September 1954, the first delivery of 479 F-100A Fighter Wing daytime. But then the wing to roll maneuver at high speed since there were several serious accidents. To solve the problem, the company assigned to the North American F-100 chief test pilot George Wales special flight. But the October 12, 1954, when George the flight envelope on the right sector flight, the plane suddenly instability, transient overload than 8G! F-100A was immediately disintegrated, George seriously injured died. November 8th, the British Air Force Brigadier General Jeffrey Stephen Johnson in Florida when the F-100A flight test crash killed. 2 days, and an F-100A crashed in a motor out of control, but fortunately the pilot to escape. U.S. Air Force ordered all F-100A all grounded - this is the F-100 development process grounded in that famous event. Cause of the accident was finally identified, the aircraft speed roll, the first body roll and yaw inertia coupling, F-100A's little tail can not provide enough directional stability, instability and cause the aircraft to a sudden accident. And limit the increase of the tail after the aircraft roll movement, F-100A fleet return to flight. Equipment Crazy race in that era of aviation, the world number one position makes the supersonic Air Force F-100 almost a Thunderbird, By 1964, the U.S. Air Force and that the F-100 transonic have been insufficient to demonstrate their status, with twice the speed of sound wondering F-105B But the best fighter-bomber does not equal good performance machine, installed F-105B soon, when in May, July 1968, After F-100D in the October 21, 1967, volley exploded, the pilot parachute to escape Captain 麦瑞尔麦克 pg. The accident caused a U.S. Air Force's attention. Prior to deployment in South Vietnam because the F-100 there had been several cases of unexplained accidents are on the plane pulled up to the process of Yang bomb crashed. According to the One solution is to evacuate the aircraft away from the airport and into the protective capability with nuclear bunker, nuclear strike, after the aircraft can be a special bracket off by a rocket-propelled, so interceptor that scrambled to intercept, the concept is Zero Emission - ZEL (Zero-Length Launch).
Nearly 6 tons of rocket thrust, can be 4 seconds of the time a 16-ton aircraft accelerate to 482 km / hour. October 12, 1956, North American Airlines to obtain the contract, so that the last batch of 148 F-100D has ZEL capacity. USAF loaned two North American F-100D, the ZEL system testing. North American Aviation's rocket propulsion division has developed a solid rocket motor can be installed after the bottom of the fuselage F-100D. The engine can produce 58,970.44 kg of thrust and continue to four seconds, enough to make F-100D speed in 4 seconds to accelerate from 0 to 482.70 km / hr. After running out of fuel rocket engine off, F-100 by its own power to continue to climb. Launched during the actual machine before the launch weight of 5 times, which first launched in December 12, 1957 to. March 26, 1958, conducted its first F-100D real machine launch. Al Blackburn test pilot climbed into the F-100, start the engine, put the throttle full afterburner, and then ignited the rocket engine. In 4 seconds, he accelerated to 482.70 km / h into the sky, the rocket engine shed, Blackburn entered the standard traffic pattern to land safely. But in his second flight, CHI Turbo Ceramic Flat Iron, the rocket did not fall off after the engine burn, Blackburn had to eject. The following 20 tests have been successful, the aircraft mounted with the standard plug-in (including the nuclear model) successful launch. Although the ZEL high reliability, the operation is also simple, but the situation eased and the aircraft performance improvements, [5] To the early 60s, was surprised to find active duty U.S. Air Force F-100 almost no two are the same, aircraft maintenance and logistical support to the serious difficulties. Thus, since 1962, the Air Force began to about 700 F-100D / F modifications to standardize and upgrade, project code-named The goal: expansion of the aircraft available varieties of conventional ammunition, and enhance the use of flexibility; reduce the weight of the aircraft; unified cockpit layout; the whole machine re-wiring the electrical system. In appearance, after a Meanwhile, the modified aircraft have also changed the production batch number, the specific approach is based on the original batch add . The entire conversion project was completed in 1965. Vietnam Vietnam War was F-100 participated in the largest war. The aircraft was given two basic tasks: combat air patrols to stop the MiGs attack aircraft raid on one's own;-to-ground attack. In addition, the front of the machine and sometimes also responsible for air traffic control task. From 1964 to 1971, F-100 fleet of more than 30 million times out fighting. February 1964, Tactical Air Force 615 Tactical Fighter Squadron was ordered to Vietnam, Da Nang Air Base stationed. June 9, the Department sent the first goal of the bombing of Laos. Subsequently, on August 17, 401 Tactical Fighter Wing stationed in Tan Son Nhat base. The next day, the first aircraft F-100D (serial number 56-3085) was shot down over Laos on. To the end of the year, a total loss of the two F-100. 1965 April 1, 1965, F-100D first run escort missions, F-105 attack cover of Thanh Hoa Bridge. 3 days later, F-100D partner again with the F-105 attack Dumay Bridge. North Vietnam and came to intercept the MiG -17 encounter, the outbreak of the first air combat in the Vietnam War. Melee two U.S. aircraft were shot down. In fact, the lack of advanced radar and air to air missiles, F-100 is not suitable for air operations in the contest and the MiGs did not get a success. Therefore, the implementation was used for ground attack missions. F-100 design, but after all, old, even for ground attack, the combat radius, payload is smaller than F-105 and later the F-4 rookie, especially its structural strength of the body can not meet the high-speed low-altitude bombing requirements, so the main responsible for the fighting in South Vietnam a secondary task - typically a staging ground for guerrilla bombing. In this task, F-100 is usually mounted two CBU-24 anti-PIP 2 750 pound bombs and napalm, and then after the bombing of its four 20 mm cannon fire repeatedly target areas for work. In 1965, the

F-100
F-100 is the original North American Airlines (International Aircraft Company has been and 入罗克韦尔) has developed the world's first supersonic jet fighter in level flight capability. Used primarily as fighter-bombers. September 1953 began the armed forces. Main types are: A, C, D, F and so on. Produced a total of over 2350 various types of aircraft, in 1959 all production. Users except the United States, as well as France, Turkey, Denmark and Taiwan. F-100 has been in combat in the Vietnam War bombing mission, the Air Force (USAF) in Vietnam, one of the main models used. Citation

Air Force speed of sound. They will be determined to develop the world's first to exceed the speed of sound in level flight in a practical fighter. February 1949, North American Aviation F-86 Sabre began to study the supersonic fighter variant, engineers 雷蒙德赖斯 and 埃德加舒默 Germany (P-51 Mustang's designers) in the company self-financing support began to study how to make knives to achieve supersonic speed in level flight. The results show that: Just F-86 wing sweep from 35 degrees to 45 degrees can get this ability, but the wind tunnel tests showed that the maximum speed can only increase the sweep angle increased slightly near the speed of sound encountered the sound barrier, or can not be reached supersonic speed in level flight. Facts have obvious improvement only for aerodynamic shape is not enough to achieve the goal of supersonic, but also the need for greater thrust - much larger than before. This General Motors Allison Division presented a way to provide 4,082.57 kg of thrust J35 engine variants, F-86 is almost twice the thrust of the J47. GE also made a modified J47 engines, rated thrust 4,264.02 kg afterburning 5,897.04 kg. September 4, 1949, North American Airlines decided to concentrate all resources in the development of F-86D's improved all-weather interceptor, and to ensure the availability of supersonic performance. Plan modified by General Electric J47 engine, the 10,668 meters in height will be able to reach top speed of Mach 1.03. This However, when presenting the program to the Air Force but was rejected, U.S. Air Force instructed the North American Aviation to design a daytime fighter. After a some modifications, in January 1951, North American Aviation submitted to the U.S. Air Force, This is a daytime high performance fighter aircraft, in many ways with the U.S. Air Force also rejected the proposal, but considered that the design has developed into the potential for air superiority fighter. A program under the North American Airlines called the It combines Estimated at 10,668 meters above the ground can reach Mach 1.3 (1,383.74 km / h) maximum speed. Combat radius of 1,078.03 km, combat weight of 10,773.45 kg ordnance four 20-mm T-130 cannon. North American Airlines asked the U.S. Air Force funded the purchase of two October 1951, although previous researchers have worried that the key to F-86 fighter-based design in daytime would be too complex and expensive, USAF Committee decided to start the This is because as the outbreak of the Korean War, US-Soviet tensions simmering, the Air Force 45, the Commission now only hope that his sword in service as soon as possible to ensure the Air Force's air superiority. To speed up the progress of military service, they decided not to directly verify the prototype through production, This is a high-risk decision-making, drawing on the World War II B-29's production model, the benefits can make a paper airplane is still available to the Air Force as soon as possible, but on the other hand will bear great technical and the cost of risk, because once discovered during the prototype test unexpected problem, we must have been in service and the aircraft is to improve the production line, and bear the resulting long delays. However, taking into account North Korea's intention to contract. November 9, North American Aviation's revisions. November 20, 1951, North American began a hundreds of U.S. fighters. Two prototype models for the YF-100, the company model NA-180, production for the F-100A. April 24, 1953, the first aircraft YF-100A (product number :52 -5754) has finally shipped, and in a highly confidential, the factory moved to Los Angeles from North America, Edwards Air Force Base. North American test pilot George. S. Welch (George S. Welch) on May 25, 1953 his plane made its maiden voyage, and a breakthrough in the flight speed of sound. September 15, 1953 completed the second phase of flight, YF-100A has completed 39 flights, the total number of hours 19 hours 42 minutes. October 14, Chi dazzle flat iron, 1953, the second aircraft YF-100A (product number :52-5755) first flight. F-100A (company Model NA-192) is a super tool with the first production models. First aircraft F-100A (product number :52-5756) in the September 25, 1953 the factory, and in the October 29 flight, test pilot George Welch remains. All this only occurred in the second prototype YF-100A aircraft two weeks after the first flight, super project with knives progress at an alarming rate. The end of November 1953, the first batch of three F-100A began delivery of George Air Force Base, equipped with Tactical Air Command Fighter Group 479 436 daytime daytime Fighter Squadron. Which began its 31 years of service career. [1] The design features of F-100 was first designed as a daytime air superiority fighter, the aircraft using the normal layout, nose into the air, moderate sweep under cantilever monoplane, low, flat tail and single-tail inverted T form type tail layout.
F-100 front close-up
F-100 but with the way the nose into the air, inlet air from the nose into the air intake to lower jaw in order to make room for airborne radar. Although the inlet head of least resistance, but the biggest drawback is that radar can not install the mainframe. This makes the F-100 enhance the combat capability of the future was extremely restricted. Since the aircraft after an American fighter no longer use this inlet. F-100 using conventional Pitot inlet, the nose is not used to adjust the intake shock cone. Thus, when the Sonics formed in the inlet is a great shock resistance, and seriously affect the inlet total pressure recovery. This is the F-100 remained at the maximum speed of only one of the main transonic zone. However, usually the nose into the air and the aircraft is different from the aircraft's air intake is flat round, rather than the usual are circular, which constitutes the unique shape characteristics of the aircraft. As the inlet flat garden, the upper part of the line was under the head tilt, which makes F-100 before the bottom has a good vision for the future develop into a fighter-bombers provide an objective condition. [2] F-100 with a new design of thin airfoil wings, and the relative thickness of only 7%, which greatly reduces the resistance of high-speed flight. Thus, while only 45 degree sweep of its wings (and quite subsonic MiG -17, MiG -19 far less than the contemporaries of 55 ° sweep), but still able to achieve supersonic design goals. To address the cross-plane, supersonic pitch control, F-100 Driving abandon the stabilizer and elevator into one, with a single, full-motion wing instead. F-100 tail design is a tragic chapter in the development process. The aircraft experienced a tail design in a few years from big to small and from small to big process, but this seemingly simple change has led directly to the number of outstanding pilot was killed, and more planes and November 1954 the Air Force issued a comprehensive fleet of F-100 flight ban (lifted in February the following year). As the design years earlier, F-100 does not use This can be seen by the large number of photographs, This will inevitably lead to significant increase in transonic drag. The aircraft can achieve supersonic, mainly due to J57 engine and the relatively small thickness of the wing. Overall, as a 100 There is another unofficial nickname F-100 is the first major structure in the fuselage of the aircraft used titanium alloy, and its main purpose is to avoid the result of aerodynamic heating of supersonic flight, aircraft structural strength reduction due to the design, each with a weight of F-100 titanium alloy 650 lbs. In 1952 to 1954, North American F-100 in order to produce the United States consumes 80% of total production of titanium metal (including 95% in 1953, 1954, the increase of the titanium production fell to 60%) so the cost of the F-100 is also quite expensive at that time, reaching $ 664,000. All models YF-100A
YF-100A at Edwards Air Force Base over the
prototype, only the production of 2. 300 million spent developing the person, the first YF-100A aircraft at April 24, 1953 the factory. Aircraft is equipped with a Pratt & Whitney developed the high-thrust (at the level of terms) XJ57-P-7 Turbo II structure, axial flow turbojet engine. May 25, 1953, the aircraft at Edwards Air Force Base in the first test flight, and succeeded in breaking the sound barrier. [3] F-100A F-100A of the company model is NA-192 is a super tool with the first production models. First aircraft F-100A (52-5756) in the September 25, 1953 the factory, and in the October 29 flight, test pilot is still George. Welch. All this only occurred in the second YF-100A prototype aircraft first flight two weeks after the project is over with knives progress at an alarming rate. F-100A, in most respects similar to YF-100A, but the truncated tail, and after the tail protruding above the installation of a pipeline release. Blueprint in the USAF, F-100A is set to daylight air superiority fighter, and was portrayed as the ideal successor F-86A/E/F saber. F-100A installation of four 20 mm Pontiac (Pontiac) M-39 cannon, 200 rounds each door with a bomb. M-39 has been installed in the F-86F conducted in the Korean War on the actual test, then called the T-160, issued 1,500 per minute rate of fire, muzzle velocity of 1,005.84 m / sec. The end of November 1953, the first batch of three F-100A began to deliver George (George) Air Force Base, equipped with Tactical Air Command Fighter Group 479 436 daytime daytime Fighter Squadron. The Battalion September 29, 1954 with the F-100A operational capacity. Since the self-service F-100A, USAF pilot, has been reported that the existence of their F-100A stability and control problems, the time when the wing drop tanks hanging problem is especially serious. They suspect that this is the tail area is not big enough, not enough to maintain directional stability caused. Result, most of the early F-100A was never flew over the limits of the performance envelope. North America has been reluctant to admit that this is the result of stupid tail design. Disaster finally happened, 12 October 1954, the day George experienced test pilot. Welch driving the first nine production F-100A (52-5764) to conduct a performance test dive limit in a high-G pull After starting, F-100A air disintegration. Welch ejection successful, but was part of a large piece of metal cabin body piercing seriously injured. 8 November, a visit to the Royal Air Force officer Jeffrey. D. Stephenson (Geoffrey D. Stephenson) driving an F-100A, crashed due to loss of control of Elgin (Elgin) Air Force base and died. November 9, Frank. N. Amory (Frank N. Emory) Major driving F-100A (52-5771) shot in Nevada during training over the loss of control crashes, but fortunately Emory safe ejection. November 10, USAF F-100A all ordered grounded, the total is about 70, while there are 108 in the factory super-waiting with knives have delivered fully assembled. Conducted a detailed investigation, all evidence indicates that F-100A is the source of security problems short tail, it is also the USAF pilot has been suspected. So the F-100A of the tail to change the style back to YF-100A, an increase of 27% of that tail area, has been to Mach 1.4 only when the phenomenon of instability, and this speed is the performance of the F-100A outside the envelope. After these changes, F-100A increased to 4.68 m high. RF-100A photographic reconnaissance aircraft. September 1954, six close to the completion of the F-100A was modified from the line out for the unarmed photographic reconnaissance aircraft, model RF-100A, the aircraft's serial number 6, respectively 53-1545 ~ 1548,55 -1551,55-1554. Removed and replaced before the body of the gun five surveillance cameras, the lens towards the front and sides, respectively. The camera system can not fully incorporate it into the fuselage, so had to set protrusion of the drum kits, used to position the windshield extends to the main wing trailing edge, a RF-100A of distinct characteristics. RF-100A can carry four drop tanks instead of two F-100A, because the typical mission profile for a long time need to RF-100A high-speed afterburner flight, and will not have air refueling. Because the protruding bulge, RF-100A was a F-100B-weather combat bombing type. In order to allow space for installation of radar will be moved to the fuselage belly inlet (NA-211 program, there is a program of NA-212 F-100 is the basic layout in use), and improved three-wave system for the wedge-shaped supersonic inlet Road, and then the fuselage will be moved to the back of the inlet, the inlet to form a unique backpack. Half-buried belly fuel tank of a water drop shape. Abolition of the traditional ailerons on the wings, replaced by the spoiler. Horizontal tail is still low, flat tail all acting. Tail has been redesigned, converted to all-action tail, cancel rudder - this design was later applied to the design to the Navy A3J (ie A-5 Because the application had just discovered the development of all-weather fighter-bomber. F-100B which was renamed the YF-107A September 10, 1956, the first YF-107A aircraft first flight. Lost in the competition as F-105, YF-107 quickly dismount, only the production of three prototypes. F-100C F-100C fighter-bomber is a super family with knives in the first truly operational capability of the model, dates back to the YF-100A before the first flight in October 1952, USAF requirements of North American research and development for the super wing tanks with knife , July 1953, USAF has requested a new Finally a new wing in the F-100C's design. U.S. Air Force (USAF) F-100A of the order to change the number of the last 70 bombing of agencies to combat type, model as F-100C, the company model NA-214. 1954 年 2 24, Air Force has updated the 230 F-100C. The fourth aircraft F-100A (serial number 52-5759) was used as the prototype F-100C and to be modified to extend the tip. Since the body has been completed on a facelift, F-100C wing structure bearing increased 6 points, to install removable rack can be mounted, including fuel tanks, napalm, General bombs, airborne high-speed rocket, bomb, bomb load 2,268.09 kg. Another wing structure was strengthened to withstand the local release of weapons brought sudden impact. Containing oil in order to meet the In the final design, cheap chi flat iron, F-100C F-100C with single point pressure refueling port, compared to the gravity refueling F-100A is a great way to progress, installed in the wing, detachable air by tubing to F-100C equipped with air refueling. First production model of the F-100C (53-1709) on October 19, 1954 off the assembly line, because this time all the F-100A are grounded in the tail waiting to solve the problem, so that the aircraft is qualified USAF reception. January 17, 1955, the North American test pilot George. Hoskins (George Hoskins) flew its first flight. It has the F-100A aircraft in early-type short tail, cheap chi straighteners, tail high after the conversion. May 27, 1954, USAF F-100C will be the order total to 564, is more than double the original, but in the September 27 contract was again amended, to the last of 224 F-100D. F-100C starting from April 1955 to deliver the Tactical Air Command. Texas Foster (Foster) Daytime Air Force Base 450 Fighter Squadron became the first unit equipped with F-100C, and in July 14, 1955 have the capability. The end of 1956, F-100C into the Air Force stationed in Japan, Fifth Battalion 8 fighter-bombers in service. The first F-100C in a small number of installed J57-P-7 engine, rated thrust 4,400.10 kg afterburning 6,713.56 kg. Most F-100C (up to 101 aircraft) of the power plant is the J57-P-7 of the improved J57-P-21, -21 type of 4,626.91 kilograms of rated thrust with afterburning 7,257.90 kg, and offers greater at high altitude thrust, the F-100C maximum increase of about 64.36 kilometers per hour, climb to 10,668 meters, time-consuming by 10%. F-100C One of the more serious problems with the F-100A the same: when the high-speed access without control yaw and roll tendencies. From the 146 F-100C began, the introduction of the yaw damper. This improvement seems to help alleviate this problem, we first factory F-100C have carried out this modification. From the 301 F-100C, the pitch damper was added to the horizontal tail control system, which will help attenuation over the longitudinal oscillations with knives. In order to solve the problem J57 engine compressor stall, installed inside the engine valves to avoid gas accumulation phenomenon. August 20, 1955, Horace. A. Hans (Horace A. Hanes) Colonel driving F-100C set a new world speed record. He Mojave (Mojave) desert over the 12,192-meter section of 15-25km altitude routes running back and forth twice, with an average speed of 1,322.82 km, becoming the first supersonic aviation history of World Records, is the first record created in the high altitude , past records are created in low altitude. September 4, 1955, Carlos. Talbott (Carlos Talbott) F-100C Colonel driving across America coast to coast, with an average speed of 982.66 km, with a total length of 3,740.93 km. For this feat, Carlos. Colonel Talbot was awarded the Bendix (Bendix) trophy (Vincent. Bendix (Vincent Bendix) for the flight across the continental United States set up the trophy race). F-100C produced a total of 476, the last one delivered in July 1956. There have been over 150 F-100C deployed in Europe, the main base in Bitburg, Germany (Bitburg), 福斯滕费尔德 Brook (Furstenfeldbruck), Landstuhl Seoul (Landstuhl), and the West Hahn (Hahn) , also deployed in the Morocco and the Netherlands. U.S. Air Force F-100C is also very short service life, quickly replaced by F-100D. Exit after first-line F-100C transferred to the ANG, 1959 first in mid-ANG squadron began equipped F-100C. Air Force F-100C remaining in the late 1950s, mostly for training missions. JF-100C NASA research and test machine. Only one (production serial number :53-1709). TF-100C two-seat trainer prototype, converted from the F-100C, only one (production serial number :54-1966). August 1956, TF-100C first flight. The aircraft performed well in flight test, F-100F two-seat trainer which come out. However, only TF-100C aircraft finally April 9, 1957 crash. F-100D's battle with nuclear bomb type attack. January 24, 1956, F-100D prototype (production number :54-2121) first test flight. When to stop production until Gaixing Ji produced a total of 1274, F-100 accounted for 50% of total output, F-100 is the most important modifications. The machine is actually a modified C-type, North American proposed a total of four improvement program, the company numbers were NA-223, NA-224, NA-235 and NA-245.
single flying F-100D
in appearance, the machine still retains C-6 wing pylons, but the delivery method used to improve the ejection, rather than the original gravity free delivery method. Vertical tail and rudder area is increased, then the square edge of the upper fairing also increased to accommodate the radar warning receiver, antenna and emergency discharge tubing. F-100D improvement is mainly reflected in avionics equipment. The aircraft is equipped with 明尼珀利斯 - Honeywell developed MB-3 automatic pilot, making it the first equipped with supersonic aircraft autopilot. MB-3 greatly reduces the introduction of pilot workload, making the pilot's hands can be freed for access to navigational charts or weapons targeting, and in the MB-3 aircraft under the control continues to the target. However, the system can only be used in stand-alone flight, when the F-100D formation flying, MB-3 is usually closed. Other avionics systems include: AN/APG-30 fire control radar,, AN/AJB-1 AN/AJB-1 low altitude bombing system (LABS, improved, can be used for delivery of nuclear bombs), AN/AAR-4 infrared search system, AN/ALR-45 radar warning receiver, AN/ALE-2 chaff dispenser, as well as navigation and communications equipment. When a nuclear attack, F-100D could carry MK-7, MK-38, MK-43, Mk 28 EX, chi turbo flat iron, Mk 28 RE, TX-43, TX-43 X1, and other types of nuclear bombs (usually left hanging mount point and the fuselage centerline mount point), explosive power from 1000 to 10,000,000 tons TNT equivalent range. Bomb the main mode of a In a typical attack missions, F-100D from a minimum altitude of 900 km / h speed penetration, close to the target to an overload 4G pull up to be a catty fighting, in the process the computer automatically calculate and put a nuclear bomb, the plane arrived backflip vertices to level to do a half roll, and then speed off to escape the damage radius of a nuclear bomb. [4] QF-100D unmanned drone. From the retired F-100D converted from, removed all the ordnance system for air weapons testing. A total of 218 modifications. F-100F two-seat trainer Serial, F-100 final production. The aircraft in March 7th, 1957 first test flight. To stop production in 1959, produced a total of 339. Although the trainer, but the F-100F retains the ability-to-air combat and ground attack capability, but reduced load of bombs, gun is also reduced to two. Later part of the F-100F has been modified specifically to-air missile attacks on positions and artillery fire control system with a radar position, the planes is called QF-100F unmanned drone. Converted from the F-100F unmanned drone. When the last one F-100F two-seat machine after delivery, with knives in the production of super-history come to an end, the total number of super-production with a knife last reached 2,294 aircraft, including 359 Columbus plant. F-100J F-100J program is based in Japan of foreign military assistance to provide all-weather interceptor, but the Japanese government was not interested, and therefore remain in the conceptual stage. F-100K F-100K is the F-100F Dress J57-P-55 models after the engine has never been produced. F-100L F-100L is the F-100D Dress J57-P-55 models after the engine has never been produced. F-100N F-100N is the F-100D of the reduced form, after the installation of a simplified electronic system available to the NATO member, but failed to get orders. F-100S F-100S is the installation of 1964 Rolls - Royce (Rolls-Royce) Company RB.168-25R Spey turbofan engines of the F-100F, chi pink dazzle limited edition, plans to establish production line in France, 200 F -100S, but not realized. Service speed race course a successful maiden flight from the YF-100A, the Air Force in turn use it to create the world speed record flight. Speed record at the time by the Navy's XF4D-1 YF-100A first time and the flight speed record attempt in the traditional sectors on 3 km, although the XF4D-1 does more than speed records, but beyond the range of less than 1%, according to regulations recognized. October 29, 1953 Pite Ai Winster Colonel driving again, the first aircraft attack the YF-100A, in the 15 km leg to create a 755.149 miles / h record, succeeded the throne first hand from the Navy won back. Grounding incident in September 1954, the first delivery of 479 F-100A Fighter Wing daytime. But then the wing to roll maneuver at high speed since there were several serious accidents. To solve the problem, the company assigned to the North American F-100 chief test pilot George Wales special flight. But the October 12, 1954, when George the flight envelope on the right sector flight, the plane suddenly instability, transient overload than 8G! F-100A was immediately disintegrated, George seriously injured died. November 8th, the British Air Force Brigadier General Jeffrey Stephen Johnson in Florida when the F-100A flight test crash killed. 2 days, and an F-100A crashed in a motor out of control, but fortunately the pilot to escape. U.S. Air Force ordered all F-100A all grounded - this is the F-100 development process grounded in that famous event. Cause of the accident was finally identified, the aircraft speed roll, the first body roll and yaw inertia coupling, F-100A's little tail can not provide enough directional stability, instability and cause the aircraft to a sudden accident. And limit the increase of the tail after the aircraft roll movement, F-100A fleet return to flight. Equipment Crazy race in that era of aviation, the world number one position makes the supersonic Air Force F-100 almost a Thunderbird, By 1964, the U.S. Air Force and that the F-100 transonic have been insufficient to demonstrate their status, with twice the speed of sound wondering F-105B But the best fighter-bomber does not equal good performance machine, installed F-105B soon, when in May, July 1968, After F-100D in the October 21, 1967, volley exploded, the pilot parachute to escape Captain 麦瑞尔麦克 pg. The accident caused a U.S. Air Force's attention. Prior to deployment in South Vietnam because the F-100 there had been several cases of unexplained accidents are on the plane pulled up to the process of Yang bomb crashed. According to the One solution is to evacuate the aircraft away from the airport and into the protective capability with nuclear bunker, nuclear strike, after the aircraft can be a special bracket off by a rocket-propelled, so interceptor that scrambled to intercept, the concept is Zero Emission - ZEL (Zero-Length Launch).
Nearly 6 tons of rocket thrust, can be 4 seconds of the time a 16-ton aircraft accelerate to 482 km / hour. October 12, 1956, North American Airlines to obtain the contract, so that the last batch of 148 F-100D has ZEL capacity. USAF loaned two North American F-100D, the ZEL system testing. North American Aviation's rocket propulsion division has developed a solid rocket motor can be installed after the bottom of the fuselage F-100D. The engine can produce 58,970.44 kg of thrust and continue to four seconds, enough to make F-100D speed in 4 seconds to accelerate from 0 to 482.70 km / hr. After running out of fuel rocket engine off, F-100 by its own power to continue to climb. Launched during the actual machine before the launch weight of 5 times, which first launched in December 12, 1957 to. March 26, 1958, conducted its first F-100D real machine launch. Al Blackburn test pilot climbed into the F-100, start the engine, put the throttle full afterburner, and then ignited the rocket engine. In 4 seconds, he accelerated to 482.70 km / h into the sky, the rocket engine shed, Blackburn entered the standard traffic pattern to land safely. But in his second flight, CHI Turbo Ceramic Flat Iron, the rocket did not fall off after the engine burn, Blackburn had to eject. The following 20 tests have been successful, the aircraft mounted with the standard plug-in (including the nuclear model) successful launch. Although the ZEL high reliability, the operation is also simple, but the situation eased and the aircraft performance improvements, [5] To the early 60s, was surprised to find active duty U.S. Air Force F-100 almost no two are the same, aircraft maintenance and logistical support to the serious difficulties. Thus, since 1962, the Air Force began to about 700 F-100D / F modifications to standardize and upgrade, project code-named The goal: expansion of the aircraft available varieties of conventional ammunition, and enhance the use of flexibility; reduce the weight of the aircraft; unified cockpit layout; the whole machine re-wiring the electrical system. In appearance, after a Meanwhile, the modified aircraft have also changed the production batch number, the specific approach is based on the original batch add . The entire conversion project was completed in 1965. Vietnam Vietnam War was F-100 participated in the largest war. The aircraft was given two basic tasks: combat air patrols to stop the MiGs attack aircraft raid on one's own;-to-ground attack. In addition, the front of the machine and sometimes also responsible for air traffic control task. From 1964 to 1971, F-100 fleet of more than 30 million times out fighting. February 1964, Tactical Air Force 615 Tactical Fighter Squadron was ordered to Vietnam, Da Nang Air Base stationed. June 9, the Department sent the first goal of the bombing of Laos. Subsequently, on August 17, 401 Tactical Fighter Wing stationed in Tan Son Nhat base. The next day, the first aircraft F-100D (serial number 56-3085) was shot down over Laos on. To the end of the year, a total loss of the two F-100. 1965 April 1, 1965, F-100D first run escort missions, F-105 attack cover of Thanh Hoa Bridge. 3 days later, F-100D partner again with the F-105 attack Dumay Bridge. North Vietnam and came to intercept the MiG -17 encounter, the outbreak of the first air combat in the Vietnam War. Melee two U.S. aircraft were shot down. In fact, the lack of advanced radar and air to air missiles, F-100 is not suitable for air operations in the contest and the MiGs did not get a success. Therefore, the implementation was used for ground attack missions. F-100 design, but after all, old, even for ground attack, the combat radius, payload is smaller than F-105 and later the F-4 rookie, especially its structural strength of the body can not meet the high-speed low-altitude bombing requirements, so the main responsible for the fighting in South Vietnam a secondary task - typically a staging ground for guerrilla bombing. In this task, F-100 is usually mounted two CBU-24 anti-PIP 2 750 pound bombs and napalm, and then after the bombing of its four 20 mm cannon fire repeatedly target areas for work. In 1965, the
