Inert 2.75-Inch FFAR and 70mm Hydra Aircraft Rockets

Explore inert and deactivated 2.75-inch Mk 4 and Mk 40 Folding-Fin Aircraft Rockets, 70mm Hydra rockets using Mk 66 Wrap-Around Fin Aircraft Rocket motors, warhead sections, fuzes, fins, launcher components, and related accessories. The 2.75-inch and 70mm measurements describe the same nominal rocket caliber across different generations. Earlier FFAR systems used folding fins, while the later Mk 66 motor introduced wrap-around fins and became the foundation of the Hydra 70 family. These modular rockets have been configured for multiple fixed-wing aircraft and helicopter missions. Category items contain no live warhead fill, explosive, or propellant material and are intended for collecting, museum exhibits, aviation displays, or technical study.
