H-25 MULE (UH-25B)
Delivered to the Navy in early 1949, the all metal Piasecki HUP-3 "Retriever" was of the same twin rotor design as the company's earlier "Flying Banana". As the first production helicopter equipped with an auto-pilot, the HUP-3 was designed to fly and hover on instruments.

However, the system was unreliable and saw no significant utilization. An electrically operated hatch door in the fuselage allowed litters to be hoisted directly into the cabin of the aircraft, and the small, compact fuselage enabled it to be stowed aboard aircraft carriers without having to fold the rotor blades. 

Capable of carrying a two-man crew and five passengers, the UH-25 was used primarily by the Navy for air-sea rescue, liaison, replenishment, and plane guard duties, all of which were performed admirably during the Korean War. Some versions were equipped with sonar devices for use as anti-submarine helicopters. At the height of their career in the Navy, the "Retrievers" were carried aboard all aircraft carriers of the fleet.

A total of 339 production models were built for use by the United States Navy and Army, the Royal Canadian Navy and the French Navy.

The Museum's HUP-3 is currently being restored.
