The HUP Retriever was an early tandem rotor helicopter and entered service in 1949 as a general purpose transport and rescue helicopter operating from carriers and other ships. Powered by the same engine which drove the Sherman tank in World War II, the HUP is notable for having the pilot’s seat on the left, unlike other helicopters, because of the rescue hatch’s location in the cockpit. Superceded by the UH-2 Seasprite in the early 1960s, the HUP’s success inspired further work in tandem rotor designs culminating in the CH-46 Sea Knight.
