Mk 4 Mighty Mouse Folding-Fin Aerial Rocket (FFAR)
In the 1950s, the name Mighty Mouse was unofficially applied by the United States Air Force to the 2¾-inch (70 mm) FFAR (Fin-Folding Aerial Rocket) weapons used by various USAF interceptor aircraft against bombers. The Mighty Mouse rockets were carried by the F-86D Sabre, F-89 Scorpion, F-94 Starfire, and F-102 Delta Dagger.
