Grumman G-118

The Grumman G-118 (sometimes called the XF12F, though this was never official ) 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, 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.
