Vought-Sikorsky OS2U Kingfisher
Vought-Sikorsky Aircraft Division's OS2U Kingfisher was the U. S. Navy's primary ship-based, scout and observation airplane during World War II. Rex Beisel, a design engineer at Vought-Sikorsky Aircraft Company, crafted the OS2U in 1937. Beisel also designed the Vought F4U Corsair fighter. Beisel's Navy scout was a two-seat monoplane that employed revolutionary spot welding construction to create a smooth, non-buckling fuselage structure. He also used old technology to save weight and increase performance when he covered the wings with fabric aft of the main spar.
The Kingfisher handled well in slow flight, thanks to several innovative control features. In addition to the deflector plate flaps that hung from the trailing edge of the wing, the ailerons also drooped at low airspeeds to function much like extra flaps. Beisel also incorporated spoilers to supplement aileron control at low speeds. The Kingfisher could carry a respectable load. For antisubmarine work, ordnance men could suspend two 45 kg (100 lb) bombs or two 146 kg (325 lb) depth charges. A fixed .30 caliber machine gun was mounted in front of the pilot to fire forward. A gunner seated several feet behind the pilot fired another .30 caliber machine gun on a flexible mount.
The Navy contracted for the prototype XOS2U-1 on March 22, 1937, and this airplane first flew in July 1938, equipped with an air-cooled Pratt & Whitney R-985-4 Wasp Junior radial engine. The first production Kingfisher, the OS2U-1, was delivered early in 1940 and assigned to the battleship "USS Colorado." The Kingfisher could perform a variety of tasks - training, scouting, bombing, tactical and utility missions such as towing aerial gunnery targets and chasing practice torpedoes, and even anti-submarine warfare in the Atlantic Ocean. Most OS2Us operated in the Pacific Theater where Kingfisher pilots rescued many downed airmen. In 1942, a Navy pilot flying a Kingfisher rescued America's World War I ace, Capt. Eddie Rickenbacker, and the crew of a B-17D Flying Fortress forced to ditch in the Pacific. With Rickenbacker and two other passengers, the bomber and its five-man crew had left Hickam Field, Hawaii, bound for Canton Island in the Phoenix Islands group, 2,898 km (1,800 miles) southwest of Hawaii. The Flying Fortress wandered off course and the crew got lost. When the aircraft eventually ran out of fuel and ditched, the eight survivors put to sea aboard three life rafts. Several weeks passed without food or water. By chance, a Kingfisher crewed by Lt. Willam F. Eadie, pilot, and L.H. Boutte, radioman, spotted the raft carrying Rickenbacker and two other crewmen. Eadie strapped the sickest man into the gunner's seat, and then he lashed Rickenbacker and another man to each wing. A Kingfisher could never takeoff with such a load, so Eadie began to taxi toward his base on Funafuti Island, about 64.4 km (40 miles) distant. Soon a Navy Patrol Torpedo boat met the airplane and the other five men were soon rescued. Only one of the eight failed to recover from the long ordeal.

Vought F4U Corsair
Development of the Corsair began in 1938, when the US Navy issued a request for a new single-seat carrier-based fighter. The Chance-Vought company won the contract with their unique, gull-winged airframe pulled by the largest engine then available, the Pratt & Whitney R-2800 Double Wasp. The wing design was necessitated by the tall landing gear which was, in turn, necessitated by the huge propeller required to propel the plane at the desired high speeds.
The prototype of the Corsair was first flown on 29 May 1940, but due to design revisions, the first production F4U-1 Corsair was not delivered until 31 July 1942. Further landing gear and cockpit modifications resulted in a new variant, the F4U-1A, which was the first version approved for carrier duty.
The Corsair served with the US Navy, US Marines, the Royal Navy's Fleet Air Arm, and the Royal New Zealand Air Force (and later, the French Aeronavale), and quickly became the most capable carrier-based fighter/bomber of the war. Demand for the aircraft soon overwhelmed Vought's manufacturing capability, resulting in additional aircraft being produced by the Goodyear Company (as the FG-1) and the Brewster Company (as the F3A-1). Production ceased in 1952. Over two dozen Corsairs are believed to be still airworthy, most in the United States.

FMA Vought Pampa 2000
Video de promocion en ingles del pampa 2000.
El 30 de abril de 1990 se firmó un histórico convenio entre la FMA y la compañÃa Vought Aircraft (ex-LTV) por el cual la firma se hacÃa cargo de la presentación del IA-63 (rebautizado como Pampa 2000).
El Pampa 2000 constituyó el último gran esfuerzo de la FMA en manos estatales para lograr un contrato de fabricación importante que salvara su mala situación económica.
El programa denominado J-PATS (Joint - Primary Training Aircraft Sistem = Programa Conjunto de Sistema Avión Entrenador) constituÃa un requerimiento de USA para reemplazar a sus viejos entrenadores T-37B de la USAF y T-34C de la US-Navy.
El vuelo inaugural del FMA-Vought Pampa 2000 se efectuó el 25 de mayo de 1993 al mando del piloto norteamericano John Hoffman en las instalaciones de Forth worth, Texas.
Se calculaba una necesidad de 700-750 aviones y un contrato de mas de 1.600 milllones de dólares para el ganador. Varias fábricas de distintos paÃses acudieron para intentar llevarse el jugoso contrato. Entre ellas y con sus respectivos modelos:
- Vought Pampa 2000 Jet
- Grumman S 211A Jet ( SIAI- Marchetti)
- Rockwell Ranger 2000 Jet
- Cessna Citation Jet
- Northrop Grumman Super Tucano Turboprop ( Embraer Tucano)
- Lockheed T-Bird 11 Jet
- Beech PC-9 Turboprop ( Pilatus PC-9)
La Vought al no tener un diseño propio de entrenador, postulaba al Pampa 2000 para el J-PATS. Se enviaron a la fábrica que Vought posee en Dallas (Texas) los aviones EX-02 y los aviones de serie E-812 y E-814. Estos dos últimos fueron modificados con varias incorporaciones de aviónica, nuevos sistemas hidráulicos, asientos eyectables Martin-Barker MKUS 16LC y demás modificaciones.
También incorporaba a pedido de los estamentos norteamericanos, una pantalla de color LCD (cristal liquido) que reunÃa mucha de la información suministrada anteriormente por medios analógico como relojes y variómetros:
Luego de acumular cientos de horas de pruebas, todos los pilotos que volaron el P-2000 coincidieron en sus excelentes caracterÃsticas. Muchos observadores y expertos militares coincidÃan en predecir que el más probable ganador serÃa un avión de motor a reacción.
Sin embargo, a mediados de 1996, después de un año de retraso en el otorgamiento del contrato, las autoridades norteamericanas se decidieron por el más barato avión suizo de turbohélice Pilatus PC-9, denominado en USA Beechcraft T-6 Texan II.
Ese fue el golpe final para la altamente deficitaria FMA. Tras el fracaso del avión ejecutivo conjunto con Brasil CBA-123 Vector y la gran inversión en el P-2000, la fabrica fue privatizada y otorgada en concesión a Lockheed-Martin Aircraft por veinticinco años. El gobierno Argentino retendrÃa para sà una 25 % de las acciones de la nueva empresa denominada LMAASA ( Lockheed Martin Aircraft Argentina Sociedad Anónima).
Pese a todo, la experiencia del P-2000 no se perdió enteramente y servirÃa de base para el nuevo AT-63.
