The Grumman G-118 (sometimes called the XF12F, though this was never official [2] ) was a design for an all-weather missile-armed interceptor aircraft for use on US Navy aircraft carriers. Originally conceived as an uprated F11F Tiger, it soon evolved into a larger and more powerful project. Although two prototypes were ordered in 1955, development was cancelled the same year in favor of the F4H Phantom II before any examples were built. Grumman's next (and last) carrier fighter would be the F-14 Tomcat, ordered in 1968.

Design

The Grumman Design 118 was a two-seat, twin-engined, rocket augmented, carrier-based all-weather supersonic fighter aircraft. It had a 45° swept wing, a "T-tail" empennage, two small folding ventral fins, and a landing gear of tricycle configuration. For ejection, the tandem crew were encapsulated and ejected downwards. It also featured a boundary layer control system to improve low speed handling.

The G-118 was to be powered by two J79-GE-3 engines, with accommodations for the more powerful J79-GE-207 engines each producing 18,000 lbf of afterburning thrust. Similar to the contemporary Vought XF8U-3 Crusader III, it was designed with an additional throttleable liquid-fueled rocket engine using a mixture of JP-4 fuel and hydrogen peroxide oxidizer which produced 5,000 lbf of thrust. [3]

Armament stores would have been under the fuselage in two semi-recessed hardpoints for the AIM-7 Sparrow air-to-air missile and an internal weapons bay for an additional AIM-7 or three AIM-9 Sidewinder missiles.

The Grumman F-14 Tomcat is an American carrier-capable supersonic, twin-engine, two-seat, twin-tail, all-weather-capable variable-sweep wing fighter aircraft. The Tomcat was developed for the United States Navy's Naval Fighter Experimental (VFX) program after the collapse of the General Dynamics-Grumman F-111B project. A large and well-equipped fighter, the F-14 was the first of the American Teen Series fighters, which were designed incorporating air combat experience against MiG fighters during the Vietnam War.

The North American FJ-2 and FJ-3 Fury are a series of swept-wing and carrier-capable fighters for the United States Navy and Marine Corps. The FJ-2 resulted from an effort to navalize the North American F-86 Sabre operated by the United States Air Force. These aircraft feature folding wings, and a longer nose landing strut designed to increase angle of attack upon launch and to accommodate a longer oleo to absorb the shock of hard landings on an aircraft carrier deck.

The Douglas F5D Skylancer is a development of the F4D Skyray jet fighter for the United States Navy. Starting out as the F4D-2N, an all-weather version of the Skyray, the design was soon modified to take full advantage of the extra thrust of the Pratt & Whitney J57 eventually fitted to the Skyray instead of the Westinghouse J40 originally planned.

The North American XF-108 Rapier was a proposed long-range, high-speed interceptor aircraft designed by North American Aviation intended to defend the United States from supersonic Soviet strategic bombers. The aircraft would have cruised at speeds around Mach 3 with an unrefueled combat radius over 1,000 nautical miles, and was equipped with radar and missiles offering engagement ranges up to 100 miles (160 km) against bomber-sized targets.

<span class="mw-page-title-main">Douglas F6D Missileer</span> Proposed US Navy fighter jet

The Douglas F6D Missileer was a proposed carrier-based fleet defense fighter designed by Douglas Aircraft Company in response to a 1959 United States Navy requirement. It was designed to be able to loiter for extended periods at a relatively long distance from the Navy's aircraft carriers, engaging hostile aircraft 100 miles (160 km) away with its powerful radar and long-range missiles. Since the enemy would be fired on long before they reached visual range, the aircraft had little dogfighting capability and was strictly subsonic. When doubts were expressed about the Missileer's ability to defend itself after firing its missiles, the value of the project was questioned, leading to its cancellation. Some of the Missileer's systems, primarily the engines, radar, and missiles, continued development in spite of the cancellation, eventually emerging on the ill-fated General Dynamics–Grumman F-111B and successful Grumman F-14 Tomcat years later.

The Dassault Mirage G, also known as the Mirage IIIG, was a variant of the French Dassault Mirage series of supersonic warplanes, but with a variable-sweep wing.

The Lockheed CL-1200 Lancer was a late 1960s company-funded proposal for a fighter aircraft based on the Lockheed F-104 Starfighter. The CL-1200 was conceived and marketed mainly for and to non-US military services, as an export product. As such it would have competed with combat-proven designs like the Dassault Mirage III, McDonnell Douglas F-4 Phantom II, Mikoyan-Gurevich MiG-21, and Northrop F-5E Tiger II. The CL-1200 competed unsuccessfully against proposed fourth generation designs, under the US government's Lightweight Fighter program, which would eventually result in the General Dynamics F-16 and Northrop F-17 Cobra.

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.
