The H-25 helicopter, also known as the Piasecki HUP Retriever or Army Mule, was a compact, post-war utility helicopter featuring a distinctive tandem rotor design, used by the US Navy and Army for transport, rescue (plane guard), and anti-submarine roles, noted for its sturdy build and versatility from aircraft carriers and land bases. Developed by Piasecki Helicopter Corporation (later Boeing-Vertol), it entered service in the early 1950s with a single radial piston engine and compact fuselage.
