This unmanned, radio-controlled, surveillance and anti-submarine helicopter, with coaxial, contra-rotating rotors, built in mid-1966, was one of more than 800 produced, in different versions, by the Gyrodyne Company in St.James, Long Island, New York.

DS-1482 was assigned to the United States Navy and went to sea on a WW2 destroyer which had been modernised to provide improved sonar, a small flight deck and a hangar for two drones. Transferred to the US Army in 1974 it was eventually acquired by a private individual for his collection. Years later it was spotted near Bakersfield, California, and subsequent negotiation resulted in it being sold to The Helicopter Museum in 2013.
