Piasecki HUP-1 Retriever

Piasecki Helicopter Corporation · USA · first flew 1949 · helicopter

The HUP-1 Retriever was the first production variant of Piasecki's compact tandem-rotor shipboard helicopter, designed specifically to operate from destroyer-sized warships for plane-guard and utility duties. Its overlapping tandem rotors gave a short overall length ideal for shipboard operations.

History

Following the XHJP-1 prototype, Piasecki produced the HUP-1 from 1949 for the US Navy. The design's compact tandem rotor layout allowed it to fold for below-deck stowage and operate from small ship decks. It served aboard aircraft carriers and cruisers as the primary plane-guard rescue helicopter of the early 1950s.

Variants

The HUP-2 followed with an autopilot system; the HUP-3 was a further development. The Army operated the same aircraft as the H-25 Army Mule.

Where you'll see it

Served with the US Navy from carriers and other warships from the early 1950s into the early 1960s, performing plane-guard, utility, and occasional anti-submarine duties. The French Navy also operated the type.
