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 {{avyear|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 throtteable 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.
