The Convair Model 200 was a design for a supersonic vertical takeoff and landing (VTOL) fighter requirement for the United States Navy Sea Control Ship. [1] Further versions were planned for conventional catapult launches and landing using arresting gear.
The Convair Model 200 was designed in 1973 as a single-jet fighter, that could be built in both vertical takeoff and landing (VTOL) (model 200A) and conventional takeoff and landing (CTOL) configurations (Model 201A). For the CTOL, the single Pratt & Whitney JTF22A-26A with tail hook, canard with flap, and CTOL tail cone. For the VTOL operations, the single Pratt & Whitney JTF22A-30A with a jet exhaust pipe tiltable by 90 degrees using a three-bearing swivel nozzle, and two additional lifting engines with 46.7 kN thrust each were provided behind the cockpit. The lifting engines and the swiveling nozzles were eliminated in the CTOL versions. The top speed was Mach 2. The wingspan was 27 feet 10.5 inches (8.496 m); the length was 51 feet 1.5 inches (15.583 m). The Model 200 had a cruise engine, a swept tail, two ventral fins under the fuselage, delta wings and delta canards directly behind the rectangular air intakes.
The Model 200 was proposed in a US Navy competition for a small VTOL fighter that could be carried by the Sea Control Ship, the small aircraft carriers that the US Navy was planning at the time. Neither the Model 200 nor the SCS were built. [2] However, a competitor of the Model 200, the Rockwell XFV-12 fighter aircraft, was built. The XFV-12, which could not demonstrate vertical flight, was far from meeting expectations, and the project was canceled before the second XFV-12 was completed. [3] Various models for wind tunnel tests were built for the Convair Model 200, as well as a model for researching the air currents during vertical takeoff and landing. Furthermore, a 1:1 front fuselage model including a complete cockpit layout was built.
The JTF22A-30A's swivel nozzle design would lay the groundwork for nozzle design of the F135-PW-600 on the Lockheed Martin F-35B. [4]

General characteristics
Performance
A short take-off and vertical landing aircraft is a fixed-wing aircraft that is able to take off from a short runway and land vertically. The formal NATO definition is:
A Short Take-Off and Vertical Landing aircraft is a fixed-wing aircraft capable of clearing a 15 m obstacle within 450 m of commencing take-off run, and capable of landing vertically.
A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes.
A vertical and/or short take-off and landing (V/STOL) aircraft is an airplane able to take-off or land vertically or on short runways. Vertical takeoff and landing (VTOL) aircraft are a subset of V/STOL craft that do not require runways at all. Generally, a V/STOL aircraft needs to be able to hover. Helicopters are not considered under the V/STOL classification as the classification is only used for aeroplanes, aircraft that achieve lift (force) in forward flight by planing the air, thereby achieving speed and fuel efficiency that is typically greater than the capability of helicopters.
The Lockheed Martin X-35 is a concept demonstrator aircraft (CDA) developed by Lockheed Martin for the Joint Strike Fighter program. The X-35 was declared the winner over the competing Boeing X-32 and a developed, armed version went on to enter production in the early 21st century as the F-35 Lightning II.
The Rolls-Royce Pegasus is a British turbofan engine originally designed by Bristol Siddeley. It was manufactured by Rolls-Royce plc. The engine is not only able to power a jet aircraft forward, but also to direct thrust downwards via swivelling nozzles. Lightly loaded aircraft equipped with this engine can manoeuvre like a helicopter. In particular, they can perform vertical takeoffs and landings. In US service, the engine is designated F402.
Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.
The Boeing X-32 is a concept demonstrator aircraft that was designed for the Joint Strike Fighter competition. It lost to the Lockheed Martin X-35 demonstrator, which was further developed into the Lockheed Martin F-35 Lightning II.
The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter. It has two variants; a Conventional Take-Off and Landing (CTOL) variant used in the F-35A and F-35C, and a two-cycle Short Take-Off Vertical Landing (STOVL) variant used in the F-35B that includes a forward lift fan. The first production engines were delivered in 2009.
The Yakovlev Yak-141, also known as the Yak-41, is a Soviet supersonic vertical takeoff/landing (VTOL) fighter aircraft designed by Yakovlev. Intended as a replacement for the Yak-38, it was designed as a supersonic fleet defence fighter capable of STOVL/VTOL operating from Soviet carriers. Four prototypes were built before the project's cancellation.
The Yakovlev Yak-36, also known as Izdeliye V, is a Soviet technology demonstrator for a VTOL combat aircraft.
The Curtiss-Wright X-19, company designation Model 200, is an American experimental tiltrotor aircraft of the early 1960s. It was noteworthy for being the last aircraft of any kind manufactured by Curtiss-Wright.
The Dassault Mirage IIIV, also spelled Mirage III V, was a French vertical take-off and landing (VTOL) prototype fighter aircraft of the mid-1960s developed and produced by Dassault Aviation.
The Lockheed XFV is an American experimental tailsitter prototype aircraft built by Lockheed in the early 1950s to demonstrate the operation of a vertical takeoff and landing (VTOL) fighter for protecting convoys.
The Lockheed XV-4 Hummingbird was a U.S. Army project to demonstrate the feasibility of using VTOL for a surveillance aircraft carrying target-acquisition and sensory equipment. It was designed and built by the Lockheed Corporation in the 1960s, one of many attempts to produce a V/STOL vertical take off/landing jet. Both prototype aircraft were destroyed in accidents.
The Rockwell XFV-12 was a prototype supersonic United States Navy fighter which was built in 1977. The XFV-12 design attempted to combine the Mach 2 speed and AIM-7 Sparrow armament of the McDonnell Douglas F-4 Phantom II in a VTOL fighter for the small Sea Control Ship which was under study at the time. On paper, it looked superior to the subsonic Hawker Siddeley Harrier attack fighter. However, it was unable to demonstrate an untethered vertical takeoff and its inability to meet performance requirements resulted in the program's termination.
The Short SC.1 was the first British fixed-wing vertical take-off and landing (VTOL) jet aircraft. It was developed by Short Brothers. It was powered by an arrangement of five Rolls-Royce RB.108 turbojets, four of which were used for vertical flight and one for conventional horizontal flight. The SC.1 had the distinction of being the first British fixed-wing VTOL aircraft and the first one to transition between vertical and horizontal flight modes; it was also the first VTOL-capable aircraft with a fly-by-wire control system.
A powered lift aircraft takes off and lands vertically under engine power but uses a fixed wing for horizontal flight. Like helicopters, these aircraft do not need a long runway to take off and land, but they have a speed and performance similar to standard fixed-wing aircraft in combat or other situations.
The Rolls-Royce LiftSystem, together with the F135 engine, is an aircraft propulsion system designed for use in the STOVL variant of the F-35 Lightning II. The complete system, known as the Integrated Lift Fan Propulsion System (ILFPS), was awarded the Collier Trophy in 2001.
Paul Michael Bevilaqua is an aeronautics engineer at Lockheed Martin in California, United States. In 1990, he invented the lift fan for the Joint Strike Fighter F-35B along with fellow Skunk Works engineer, Paul Shumpert.
The Sukhoi Shkval was a Soviet project for a tailsitter-type interceptor aircraft.
