Qh-50 Dash

A 1960s-era remotely-piloted Helicopter used for antisubmarine warfare on small naval vessels. Considered expendable and built largely with commercial off-the-shelf electronics, the UAV was powered by a single engine driving 20 ft (6.10m) coaxial rotors. It could carry cameras or a pair of homing torpedoes.
