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".

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.
The improved HH-3E variant would follow later, with eight built, and all 50 CH-3Es were converted to this standard. 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 air-sea rescue. The Pelican featured a search radar with a nose antenna radome offset to port, and water landing capability.
Italian Agusta built a S-61R variant, named AS-61R under license. Agusta produced 22 helicopters for the Italian Air Force. The company claimed it could re-open the production line in 36 months to build additional AS-61 helicopters.
USAF variants served in numerous air rescue squadrons and aerospace rescue and recovery squadrons of the Military Airlift Command (MAC), rescue squadrons of the Air Combat Command (ACC) and other USAF major commands worldwide. The aircraft was also used by a number of Air Force Reserve and Air National Guard rescue squadrons. All USAF HH-3Es, to include Air Force Reserve and Air National Guard, were retired in the 1990s and replaced by the current HH-60G Pavehawk.
The HH-3F Pelican was a dependable workhorse for the US Coast Guard from the late 1960s until it was phased out in the late 1990s. All USCG HH-3Fs were replaced by the HH-60J Jayhawk and those aircraft have since been upgraded to the MH-60T Jayhawk version.
Between 31 May and 1 June 1967, two HH-3Es of the United States Air Force made the first nonstop flight across the Atlantic Ocean by helicopter. Departing from New York in the early hours, the two helicopters arrived at the 1967 Paris Air Show at Le Bourget after a 30 hr 46 min flight. The operation needed nine in-flight refuelings. Both helicopters were later lost in combat operations in Southeast Asia in 1969 and 1970.
Honors and awards
Due to the nature of combat operations, particularly in Southeast Asia, many of the operational H-3 crews received honors and awards. The highest American military award, the Medal of Honor, was awarded to Captain Gerald Young, USAF, on 9 November 1967. Young piloted an HH-3E, AF Ser. No. 66-13279, of the 37th Aerospace Rescue and Recovery Squadron in an attempt to rescue a US Army Special Forces reconnaissance team trapped by enemy fire in Laos. When his aircraft was shot down, he escaped the burning wreckage and, despite severe wounds, evaded capture for 17 hours until being rescued. As a result of Captain Young's efforts, the other survivor of the crash was ultimately rescued and the bodies of those servicemembers who perished were also recovered. 
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 performed SAR missions under designation HH-3F in time of peace and C/SAR (Combat SAR) in time of crisis or during military assignment. All helicopters were operated by the 5 flights of the 15° Stormo Stefano Cagna and deployed in 4 bases across Italy.
From 1993 15° Stormo performed support missions to evacuate civilians during natural catastrophes and disasters in Italy. 15º Stormo was also engaged with SAR missions in the hostile zones of the several operations abroad where Italian Armed Forces were deployed - Somalia, Albania, Bosnia, Kosovo, Iraq and Afghanistan.
