The Piasecki HU-2 was a variant of the Piasecki HUP Retriever, a compact utility helicopter with twin overlapping tandem rotors. The HU-2 was designed for the US Navy to perform rescue and transport missions from ships and aircraft carriers. The HU-2 was powered by a single Continental R-975 radial engine and could carry up to four passengers or two stretchers. The HU-2 was also equipped with an autopilot and a winch that could lower a rescue sling through a door in the cabin. The HU-2 was one of the first helicopters to perform a loop, although this was unintentional. The HU-2 was produced from 1949 to 1954 and was later replaced by the Sikorsky H-34.
