S-61R/CH-3

Подпись:Подпись:S-61R/CH-3In 1962 tho USAF borrowed threo SH-3A helicopters from the US Navy. Used for transport as CH-3Bs, these aircraft from tho Sikorsky S-61 series impressed tho Air Force so much that it ordorod a now version for its own use. Known as tho S-61R, this transport helicopter went on to save many lives in tho CSAR (combat search and rescue) role over Vietnam as the ‘Jolly Green Giant’ and, from 1968, with the US Coast Guard as the Pelican.

Agusta built 20 HH3Fs from 1973. These were similar to US Coast Guard aircraft

S-61R/CH-3A Inflight refuelling

In 1966 the USAF revealed a series of tests using a US Marine Corps KC-130F tanker. Ten contacts of up to five minutes duration worn performed.

▼ Civilian model

Sikorsky’s own S-6IR hovers above the first USAF CH-3C. As the aircraft was designed around a USAF requirement, commercial buyers did not appear.

▲ Practice rescue

US Coast Guard machines used their search radar, hoist and amphibious capabilities to tho full. The HH-3F was used to search coastlines and out at sea.

Test boom ►

Carrying an air data boom for experimental and test purposes, tho first CH-3C. in common with others of the modol. was later upgraded to CH-3E standard.

FACTS AND FIGURES

► Two HH-3£s mode the first non-stop transatlantic hollcoptor nights in 1967, making nine tanker contacts each.

► The first S-61 R flow on 17 June 1963. almost ono month ahead of schedule.

► The CH-3E could scat up to 30 troops or carry 2270 kg (5,000 lb.) of cargo.

► At least nine USAF surplus CH-ЭЕв and HH-3Es woro purchased by tho US Coast Guard to supplement their 40 HH-3F*.

► In 1975 CH/HH-3Es bocatno the first helicopters in tho US Air National Guard.

► Variants of Sikorsky’s S-70 have replaced S-61 Rs in US service.
