QH-50 DASH

Developed in the 1950s, the U.S. Navy’s QH-50 DASH (Drone Anti-Submarine Helicopter) was the first, and so far only, operational unmanned helicopter designed for a combat role.
The DASH program had its roots in the late 1950s, when the U.S. Navy sought a way to upgrade its World War II-era destroyers to effectively counter the Soviet submarine threat. In April 1958, Gyrodyne received a contract to redesign its manned helicopter so it could be flown remotely from the deck of a destroyer carrying a torpedo. The result was the QH-50, which first flew with a safety pilot on board in 1959, while the first unmanned flight succeeded in August 1960.
Over the next decade, nearly 800 QH-50s were built, using various engines. While primarily designed for operation from a ship, the QH-50 could also be controlled from another manned aircraft or a mobile ground vehicle. It demonstrated that unmanned helicopters could drop sonobuoys and flares, perform rescues, transport cargo, illuminate targets at night, and lay down smokescreens. When equipped with TV cameras, it could also perform surveillance and target spotting.
QH-50 production ended in 1969, and in 1970 the whole DASH program was cancelled altogether.
Starting in 1973, the remaining QH-50s were used as target drones on White Sands Missile Range for surface-to-air and air-to-air missile training. The QH-50s were modified to carry tow targets so that the drone itself would only seldom be shot down. These target-towing drones are currently under the control of the U.S. Army's Program Executive Office for Simulation, Training & Instrumentation (PEO-STRI), and are still in use at WSMR.
