The Sikorsky S-61R is a developed version of the S-61/SH-3 Sea King, which 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".United States.

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.Sikorsky S-61R on avia.russian.ee 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.

The improved HH-3E variant would follow later, with eight built, and all CH-3Es converted to this standard.Chant, Christopher (1996). Fighting Helicopters of the 20th Century. Twickenham, UK: Tiger Books International PLC. ISBN 1-85501-808-X. 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.
In 1965, U. S. Coast Guard ordered a version designated, HH-3F Sea King (more commonly known by its nickname "Pelican") for all-weather water rescue. Its "water landing" ability made it a dependable workhorse from the late 1960s until it was phased out in the late 1990s. The Pelican featured a search radar with a nose antenna radome offset to port.
Italian Agusta built a S-61R variant, named AS-61R under license. Agusta produced 22 helicopters for the Italian Air Force. The company claims it could re-open the production line in 36 months to build additional AS-61 helicopters.
HH-3F of Italian Air Force
Italian Agusta began production in 1974 and delivered 22 helicopters as replacements for the Grumman HU-16 Albatross used for SAR (Search and Rescue) missions at sea. Italian Air Force AS-61R helicopters perform SAR missions in time of peace and C/SAR (Combat SAR) in time of crisis or during military assignment. All helicopters are operated by the 5 flights of the 15° Stormo Stefano Cagna and deployed in 4 bases across Italy.
From 1993 15° Stormo carry support missions to the civilians during natural catastrophes and disasters in Italy. 83º Centro C/SAR is engaged with SAR missions in the hostile zones of the several operations abroad where Italian Armed Forces are deployed - Somalia, Albania, Bosnia, Kosovo, Iraq and Afghanistan.
