The Grumman F Tomcat is an American supersonictwin-enginetwo-seat, twin-tail, variable-sweep wing fighter aircraft. It was the first such U. The F was the first of the American Teen Series fighters, which were designed incorporating air combat experience against MiG fighters during the Vietnam War. The F first flew on 21 December and made its first deployment in with the U. The F served as the U. Navy's primary maritime air superiority fighterfleet defense interceptorand tactical aerial reconnaissance platform into the s.

Iranian Fs reportedly shot down at least Iraqi aircraft during the war, while only 12 to 16 Tomcats were lost; at least half of these losses were due to accidents. The Tomcat was retired by U. Beginning in the late s, the U.

Navy sought a long-range, high-endurance interceptor to defend its carrier battle groups against long-range anti-ship missiles launched from the jet bombers and submarines of the Soviet Union. The U. McNamara wanted "joint" solutions to service aircraft needs to reduce development costs and had already directed the Air Force to buy the F-4 Phantom II, which was developed for the Navy and Marine Corps. Weight and performance issues plagued the U.

With the FB program in distress, Grumman began studying improvements and alternatives. Inthe Navy awarded Grumman a contract to begin studying advanced fighter designs.

Grumman narrowed down these designs to its design. ConnollyDeputy Chief of Naval Operations for Air Warfare, flew the developmental FA variant on a flight and discovered that it had difficulty going supersonic and had poor carrier landing characteristics. He later testified before Congress about his concerns against the official U. Department of the Navy position and, in MayCongress stopped funding for the FB, allowing the Navy to pursue an answer tailored to its requirements.

The Navy studied the need for VFAXan additional fighter that was more agile than the F-4 Phantom for air-combat and ground-attack roles. The company continued to refine the design into VFX called for a tandem two-seat, twin-engined air-to-air fighter with a maximum speed of Mach 2. It would also have a built-in M61 Vulcan cannon and a secondary close air support role. McDonnell Douglas and Grumman were selected as finalists in December Grumman was selected for the contract award in January Upon winning the contract for the F, Grumman greatly expanded its CalvertonLong Island, New York facility for evaluating the aircraft.In this instructable, I will teach you how to fold the plain awesome origami F!

This model is not nearly as hard to fold as it looks, so don't be deterred by its complex appearance. Despite the sad fact that this particular plane doesn't fly too well, it never fails to impress. If you want to see my youtube video on how to make this same model, just click How To Fold an Origami F to see a tutorial that is slightly easier to follow. So lets get started! Did you use this instructable in your classroom?

Fold it in half lengthwise, or hotdog style as some people call it, then unfold. Fold the top right corner down as shown in the picture above, then unfold. Repeat on the top left corner, then unfold. There should be one point where the center crease and the two diagonals all come together. Fold the paper down so that the new fold line crosses through this point as well.

Then unfold again. Try to keep the fold straight. It doesn't have to be exactly a quarter inch, but that is a close estimate. Again, not exact. Just keep it straight and preferably bigger than the top edge fold in the last step. This step will seem kind of complicated if you have never done one before, but it is really pretty simple.

The steps are shown in the images above. If you really cant get it, watch the video at the top of the page. It will be a lot easier to follow there.

Move both wing flaps over to the left side to start. Then fold the right edge down to the center crease as shown in the second image. Take the first wing flap from the left side and fold its edge down along the center crease just like the tail in the previous step. Then fold both wing flaps onto the right side. Form the left tail just like described in step 7, then form the wing in the same way as instructed in step 8.

When you are done, fold both wings over to the right side. Take the top wing and pull it out as far as it will go, just like in the picture.The Lockheed YF is an American prototype interceptor aircraft developed and manufactured by American aerospace company Lockheed Corporation. Johnson on 24 February ; this move was to provide plausible deniability for the CIA-operated A fleet, which closely resembled the prototype YF During the s, the YF underwent flight evaluations by the USAF, but funding to put it into operational use was not forthcoming partly due to the pressing demands of the Vietnam War and other military priorities.

However, the F program was canceled by the Department of Defense in September The AFs took the seventh through ninth slots on the A assembly line; these were designated as YFA interceptors. The first YFA flew on 7 August Johnson announced the existence of the aircraft [A] [9] on 24 February Then in Januarythe FB program was officially ended.

During flight tests the YFAs set a speed record of 2, Six successful firings of the AIM missiles were completed, and a seventh failed due to a gyro failure on one of the missiles. The initial phase of the test program included objectives aimed at answering some questions about implementation of the B Air Force objectives included exploration of its use in a tactical environment, and how airborne early warning and control AWACS would control supersonic aircraft. The NASA tests would answer questions such as how engine inlet performance affected airframe and propulsion interaction, boundary layer noise, heat transfer under high Mach conditions, and altitude hold at supersonic speeds.

The NASA budget for the 2. The YF and SR originally suffered from severe control issues that affected both the engines and the physical control of the aircraft. Wind testing at NASA Dryden and YF research flights developed computer systems that nearly completely solved the performance issues. Testing revealed vortices from the nose chines interfering with intake air, which lead to the development of a computer control system for the engine air bypasses. A computer system to reduce unstarts was also developed, which greatly improved stability.

They also developed a flight engineering computer program called Central Airborne Performance Analyzer CAPA that relayed engine data to the pilots and informed them of any faults or issues with performance and indicated the severity of malfunctions. At such high speeds even minor changes in direction caused the aircraft to change position by thousands of feet, and often had severe temperature and pressure changes. CAPCS reduced these deviations by a factor of The overall improvements increased range of the SR by 7 percent.

The YF had a real-field sonic-boom overpressure value between From Wikipedia, the free encyclopedia. American prototype interceptor aircraft. Play media.It was developed as a successor to the popular Mirage III family.

During the s, Dassault commenced development of what would become the Mirage F1 as a private venture, alongside the larger Mirage F2. Work on the F1 eventually took precedence over the more costly F2, which was cancelled during the late s.

Shortly thereafter, the type was deployed as the main interceptor of the French Air Force, a capacity which it continued to serve in until the arrival of the Mirage It later transitioned to an aerial reconnaissance role. During Junethe last French Mirage F1s was retired from service. More than Mirage F1s were manufactured between and The Mirage F1 emerged from a series of design studies performed by French aircraft manufacturer Dassault Aviation.

Both the Mirage F2 and a smaller derivative, referred to the Mirage F3, received substantial attention from both Dassault and the French Air Forcethe latter being interested in its adoption as a long-range fighter bomber as a stopgap measure prior to the adoption of the envisioned Anglo-French Variable Geometry AFVG strike aircraft.

Accordingly, in mid, Dassault decided to commence design work on the smaller aircraft, subsequently designated as the Mirage F1with the intention of producing a successor to its Mirage III and Mirage 5 fighters; [1] [3] This work was performed under a government contract in anticipation of a potential French Air Force specification for an all-weather interceptor to succeed its fleet of Mirage IIIC aircraft.

On 23 Decemberthe first prototype conducted its maiden flight.

McDonnell Douglas F-4 Phantom II

During its fourth flight, the prototype was recorded as having attained a top speed in excess of Mach 2. Despite this misfortune, during latethe Mirage F1 programme was officially adopted by the French Air Force.

On 26 Mayan order for three Mirage F1 prototypes was placed, while the larger and more expensive Mirage F2 was formally abandoned. By latethe construction of an initial batch of 85 production standard Mirage F1 had been authorised.

The later Cyrano IV-1 version added a limited look-down capability. By Octoberthe Mirage F1 was under production at both Dassault's Bordeaux facility and at SABCA 's own plant in Belgiumwork at the latter having been performed under an industrial arrangement associated to Belgium's order for Mirage 5 aircraft. The Dassault Mirage F1 was a single-engine fighter aircraft, designed to function as both an interceptor aircraft and as a capable ground attack platform.

According to Dassault, the negative performance impact associated with the increased thickness of the Mirage F1's wing over the Mirage III's counterpart had been offset by improvements made to the propulsion system.

A key area of advancement on the Mirage F1 over its predecessors was in its onboard avionics. Other avionics include an autopilot and yaw damper. Duringthe first operational deployment to be performed by French Air Force Mirage F1s was conducted during Operation Mantathe French intervention in Chad to counteract the growing Libyan encroachment in the region.

A flight of four F1Cs provided fighter cover for a strike package of eight Jaguars during the air raid against the Libyan airbase at Ouadi Doum, on 16 February.

In Novemberin response to an Ivorian air attack upon French peacekeepers, a force of three Mirage F. In Octoberthree Mirage s and three Mirage F1s were deployed at Kandahar Air Force Basewhere they flew close air support and tactical reconnaissance missions in support of international forces in Southern Afghanistan.Following reviews of proposals, the United States Air Force selected McDonnell Douglas's design in to meet the service's need for a dedicated air superiority fighter.

The Eagle first flew in Julyand entered service in It is among the most successful modern fighters, with over victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force. The F was originally envisioned as a pure air-superiority aircraft. Its design included a secondary ground-attack capability [5] that was largely unused. The aircraft design proved flexible enough that an all-weather strike derivativethe FE Strike Eaglean improved and enhanced version which was later developed, entered service in and has been exported to several nations.

As ofthe aircraft is being produced in different variants. The F can trace its origins to the early Vietnam Warwhen the U. Air Force and the U. Navy fought each other over future tactical aircraft.

Defense Secretary Robert McNamara was pressing for both services to use as many common aircraft as possible, even if performance compromises were involved. As part of this policy, the USAF and Navy had embarked on the TFX F program, aiming to deliver a medium-range interdiction aircraft for the Air Force that would also serve as a long-range interceptor aircraft for the Navy.

In JanuarySecretary McNamara asked the Air Force to consider a new low-cost tactical fighter design for short-range roles and close air support to replace several types like the F Super Sabre and various light bombers then in service. The A-4 and A-7 were more capable in the attack role, while the F-5 less so, but could defend itself. If the Air Force chose a pure attack design, maintaining air superiority would be a priority for a new airframe.

The next month, a report on light tactical aircraft suggested the Air Force purchase the F-5 or A-7, and consider a new higher-performance aircraft to ensure its air superiority. This point was reinforced after the loss of two Republic F Thunderchief aircraft to obsolete MiGs on 4 April In AprilHarold Brownat that time director of the Department of Defense Research and Engineeringstated the favored position was to consider the F-5 and begin studies of an "F-X". An official requirements document for an air superiority fighter was finalized in Octoberand sent out as a request for proposals to 13 companies on 8 December.

Meanwhile, the Air Force chose the A-7 over the F-5 for the support role on 5 November[9] giving further impetus for an air superiority design as the A-7 lacked any credible air-to-air capability.

Eight companies responded with proposals. Following a downselect, four companies were asked to provide further developments. In total, they developed some design concepts. Through this period, studies of combat over Vietnam were producing worrying results.

Theory had stressed long-range combat using missiles and optimized aircraft for this role. The result was highly loaded aircraft with large radar and excellent speed, but limited maneuverability and often lacking a gun.Proving highly adaptable, it was also adopted by the United States Marine Corps and the United States Air Forceand by the mids had become a major part of their air arms.

The F-4, like other interceptors of its time, was initially designed without an internal cannon. Later models incorporated an M61 Vulcan rotary cannon. Beginning init set 15 world records for in-flight performance, [4] including an absolute speed record and an absolute altitude record. The F-4 was used extensively during the Vietnam War. It served as the principal air superiority fighter for the U.

Air Force, Navy, and Marine Corps and became important in the ground-attack and aerial reconnaissance roles late in the war. During the Vietnam War, one U.

Navy and U. Marine Corps. Israeli Phantoms saw extensive combat in several Arab—Israeli conflictswhile Iran used its large fleet of Phantoms, acquired before the fall of the Shah, in the Iran—Iraq War.

Phantom production ran from towith a total of 5, built, making it the most produced American supersonic military aircraft. The aircraft has most recently been in service against the Islamic State group in the Middle East. InMcDonnell Aircraft began work on revising its F3H Demon naval fighter, seeking expanded capabilities and better performance. The company developed several projects, including a variant powered by a Wright J67 engine, [15] and variants powered by two Wright J65 engines, or two General Electric J79 engines.

The McDonnell design was therefore reworked into an all-weather fighter-bomber with 11 external hardpoints for weapons and on 18 Octoberthe company received a letter of intent for two YAH-1 prototypes. Then on 26 Mayfour Navy officers arrived at the McDonnell offices and, within an hour, presented the company with an entirely new set of requirements.

Because the Navy already had the Douglas A-4 Skyhawk for ground attack and F-8 Crusader for dogfighting, the project now had to fulfill the need for an all-weather fleet defense interceptor. A second crewman was added to operate the powerful radar. As in the McDonnell F Voodoothe engines sat low in the fuselage to maximize internal fuel capacity and ingested air through fixed geometry intakes.

The wings also received the distinctive "dogtooth" for improved control at high angles of attack. The Phantom made its maiden flight on 27 May with Robert C. Little at the controls.

A hydraulic problem precluded retraction of the landing gear, but subsequent flights went more smoothly.March 18, Air Views. They were constructed mostly of titanium to withstand aerodynamic heating. Fueled by JP-7, the Blackbirds were capable of cruising at Mach 3. An interceptor version developed in under the designation YFA.

The A and SR designs included leading and trailing edges made of high-temperature fiberglass-asbestos laminates. With the F interceptor program having been canceled due to budgetary constraints, the U. Air Force still requested a modern high-speed interceptor with air to air combat capabilities. The interceptor was also set to carry four long-range AIM missiles, with a range of over km and a potent pound high explosive warhead.

Such a platform was ideally suited to intercepting Soviet bombers and reconnaissance aircraft near the U. The U. Air Force placed an order for 93 F interceptors, though these were canceled when Defence Secretary Robert McNamara refused to released the necessary funds.

As a result, only three prototype interceptors were ever produced, and none ever entered service in the Air Force. The systems developed for the F did, however, serve in other potent air combat platforms.

Largely as a result of these technologies, the F would go on the become one of the most lethal American combat aircraft of all time — in the Iran-Iraq war achieving a phenomenal kills against Iraqi fighters for only three losses.

Had the F entered service, however, the Russian advantage in this field may today be less absolute? With the next generation of aircraft prizing maneuverability, and from the s stealth, far more relative to speed — a combat aircraft capable of exceeding the Mach 3.
