The Sikorsky S-61R is a twin-engine helicopter used in transport or search and rescue roles. A developed version of the S-61/SH-3 Sea King, the S-61R was also built under license by Agusta as the AS-61R. The S-61R served in the United States Air Force as the CH-3C/E Sea King and the HH-3E Jolly Green Giant, and with the United States Coast Guard as the HH-3F "Pelican".[1]
The Sikorsky S-61R was developed as a derivative of their S-61/SH-3 Sea King model. It features a substantially-revised fuselage with a rear loading ramp, a conventional though water-tight hull instead of the S-61's boat-hull, and retractable tricycle landing gear. The fuselage layout was used by Sikorsky for the larger CH-53 variants, and by the much later (though similarly-sized) S-92.
Sikorsky designed and built a S-61R prototype as a private venture with its first flight in 1963. During its development, the US Air Force placed an order for the aircraft, which was designated CH-3C. The Air Force used the CH-3C to recover downed pilots. The CH-3E variant with more powerful engines would follow in 1965.[2]

The improved HH-3E variant would follow later, with eight built, and all CH-3Es converted to this standard.[3] Known as the Jolly Green Giant, the HH-3E featured protective armor, self-sealing tanks, a retractable inflight refueling probe, jettisonable external tanks, a high-speed hoist, and other specialized equipment.[3]
In 1965, U.S. Coast Guard ordered a version designated, HH-3F Sea King (more commonly known by its nickname "Pelican") for all-weather air-sea rescue.[2] The Pelican featured a search radar with a nose antenna radome offset to port,[1][3] and water landing capability.[2]
Italian Agusta built a S-61R variant, named AS-61R under license. Agusta produced 22 helicopters for the Italian Air Force.[2] The company claimed it could re-open the production line in 36 months to build additional AS-61 helicopters.[4]
