A type: General Purpose / close support helicopter evacuation of the injured and rescue helicopter

Capacity: Two-person crew and five passengers

The HUP helicopter, Pyasetsky’s (Piasecki) response to the technical requirements for a helicopter designed specifically for sea operations, launched in 1945 by the US Navy aeronautics bureau, was designed to be compact enough to fit aboard various ships and at the same time be capable carry out vertical landing, evacuation of victims, search and protection. The company was known for its work on projects with screws located one behind the other (in tandem). Therefore, it was not a surprise that Pyasetsky adopted such an arrangement for the HUP helicopter, which was launched into mass production in 1948, after receiving an order to 22 (later increased to 32) helicopter HUP-1 «Retrayver» (Retriever).

 Manned by a crew of two and accommodating up to five seated passengers or three stretchers, the HUP-1 made its debut in the fleet at the start of the 1949 of the year. The continued development of Pyasetsky led to the creation of a HUP-2 helicopter, equipped with a Sperry autopilot. These helicopters were delivered 165 copies (some of them, which received the appropriate designation HUP-2S, was equipped with equipment to combat submarines). The interest of the army in the naval helicopter led to the company creating the H-25А helicopter, which had a booster control and a reinforced cargo floor.

They were built in the number of 70 copies in parallel with the execution of the last order of the Navy for 50 helicopters HUP-3S (three of which were delivered to the Canadian Navy). The remaining helicopters HUP-2 / -3 remained in service in the Navy and US Marine Corps for so long that in 1962 year received a new designation UH-25B / C respectively, although shortly afterwards they finally put out of operation. Today, two or three helicopters recent modifications restored in the US state of airworthiness, and even a small number of them can be seen on static display in museums across North America (including Canada).
