Early US twinjet fighter aircraft

The McDonnell FH Phantom is a twinjet, straight wing, carrier based fighter aircraft designed and first flown during late World War II for the United States Navy. As a first generation jet fighter, the Phantom was the first purely jet powered aircraft to land on an American aircraft carrier|group=N and the first jet deployed by the United States Marine Corps. Although only 62 FH 1s were built it helped prove the viability of carrier based jet fighters. As McDonnell's first successful fighter, it led to the development of the follow on F2H Banshee, which was one of the two most important naval jet fighters of the Korean War; combined, the two established McDonnell as an important supplier of navy aircraft. McDonnell chose to bring the name back with the third generation, Mach 2 capable McDonnell Douglas F 4 Phantom II, the most versatile and widely used Western combat aircraft of the Vietnam War era. The FH Phantom was originally designated the FD Phantom, but this was changed as the aircraft entered production.

In early 1943, aviation officials at the United States Navy were impressed with McDonnell's audacious XP 67 Bat project. McDonnell was invited by the navy to cooperate in the development of a shipboard jet fighter, using an engine from the turbojets under development by Westinghouse Electric Corporation. Three prototypes were ordered on 30 August 1943 and the designation XFD 1 was assigned. Under the 1922 United States Navy aircraft designation system, the letter "D" before the dash designated the aircraft's manufacturer. The Douglas Aircraft Company had previously been assigned this letter, but the USN elected to reassign it to McDonnell because Douglas had not provided any fighters for navy service in years. McDonnell engineers evaluated a number of engine combinations, varying from eight diameter engines down to two engines of diameter. The final design used the two engines after it was found to be the lightest and simplest configuration. The engines were buried in the wing root to keep intake and exhaust ducts short, offering greater aerodynamic efficiency than underwing nacelles, and the engines were angled slightly outwards to protect the fuselage from the hot exhaust blast. The construction methods and aerodynamic design of the Phantom were fairly conventional for the time; the aircraft had unswept wings, a conventional empennage, and an aluminum monocoque structure with flush riveted aluminum skin. Folding wings were used to reduce the width of the aircraft in storage configuration. Provisions for four .50 caliber (12.7 mm) machine guns were made in the nose, while racks for eight High Velocity Aircraft Rockets could be fitted under the wings, although these were seldom used in service. but no other high lift devices were used. Provisions were also made for Rocket Assisted Take Off (RATO) bottles to improve takeoff performance.
