The McDonnell Douglas F-4 Phantom II [N 1] is an American tandem two-seat, twin-engine, ... and the engine producing maximum thrust compared to earlier engines.
Two-seat all-weather carrier-based fighter for the US Navy, J79-GE-2 and -2A engines with 16,100 lbf (71.6 kN) of afterburner thrust each. Named Phantom II in 1959 and redesignated F-4A in 1962; 45 built. [1] TF-4A A small number of F-4As converted into two-seat training aircraft. F4H-1 (F-4B)
The first flight after the 50-hour qualification test, required for a new engine that is the sole source of thrust for a flying testbed, was on 8 December 1955, powering the second pre-production Douglas F4D Skyray, with the J79 in place of its original Westinghouse J40 engine as part of the General Electric development and qualification program.
The British versions of the McDonnell Douglas F-4 Phantom II (designated Phantom FG.Mk.1 and FGR.Mk.2) replaced the 16,000 lb wet thrust J79 turbojets with a pair of 20,515 lb wet thrust Spey 201 turbofans. These provided extra thrust for operation from smaller British aircraft carriers, and provided additional bleed air for the boundary layer ...
Japan selected the F-4 Phantom II as its new fighter at the end of the 1960s. On 1 November 1968, this choice was made public and Japan became one of the few countries that license-produced this aircraft. The Nihon Koku Jietai (Japan Air Self-Defense Force, JASDF) received a total of 154 F-4EJ and RF-4Es.
This proved very successful, allowing the Kurnass 2000 to exceed Mach 1 without the afterburners, and endowing a combat thrust-to-weight ratio of 1.04 (17 per cent better than the F-4E). This improved the sustained turn rate by 15 per cent, the climb rate by 36 per cent, medium-level acceleration by 27 per cent and low-level speed with 18 bombs ...
The first British Phantom (XT595) on final approach prior to landing at the McDonnell plant in St Louis, Missouri in 1966. The United Kingdom (UK) operated the McDonnell Douglas F-4 Phantom II as one of its principal combat aircraft from 1968 to 1992. The UK was the first export customer for the F-4 Phantom, which was ordered in the context of ...
XF8U-3 Crusader III (V-401) – new design loosely based on the earlier F-8 variants, created to compete against the F-4 Phantom II; J75-P-5A engine with 29,500 lbf (131 kN) of afterburning thrust, first flight: 2 June 1958, attained Mach 2.39 in test flights, canceled after five aircraft were constructed because the Phantom II won the Navy ...
