• Heavylift helicopter • Flying crane • Salvage and retrieval

This bizarre-looking but superbly performing machine has got real muscle. Called tho CH-54 Tarhe – an American Indian name meaning ‘crane’ – by soldiers and the S-64 by its makers and by civilians, the big Sikorsky SkyCrane lifts, hauls and delivers almost any cargo on a sling or in a van under its fuselage. Used In combat in Vietnam, this veteran went on to servo on construction projects, oilfields and logging sites, where the SkyCrane works today as a heavylift champion of the skies.

▼ Flying crane

The S-64 was little more than a rotor system with a cockpit on the front. The giant legs could straddle just about anything the hehcoptec could lift.

< Troopship helicopter ▲

To turn tho S-64 into a troop assault helicopter. Sikorsky designed а special pod which could be clipped underneath the aircraft. This could accommodate a largo number of fully-armed troops.

• Search and rescue helicopter • Turbine-powered • Overlooked

Conceived in the mid-1950s, the S-62 incorporated several new foaturos. The US Coast Guard was sufficiently interested to purchase the typo as tho HH-52A Seaguard. A singlo T-58 turbine, a relatively spacious fusolage and amphibious capability made tho S-62 an ideal search and rescue helicopter, particularly for coastal areas. It was capable of operating from almost any surface in just about any weather.

4 On land and water

Ono or the prototypes performs a ‘powor-off landing. As an amphibious helicopter, the HH-52 proved ideal in the coastal SAP role.

▼ Northern search and rescue

HH-52s operating from ice-broakors received а bnght orange scheme with a white stripe for greater conspicuity over the frozen sea.

▲ Rig support

First order for the S-62 came from Petroleum Helicopters, which purchased a single oxample for serving large offshore oil rigs located in the Gulf of Mexico.

In 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.

▼ Italian navy SAR

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

A 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.

In order jo satisfy the l.’SAFs requirements. Sikorsky found that.1 major redesign of the 41-3 anti-submarine ariant of the S-61 was necessary Піе company designated the new helu opter S-61 К and four versions of the basic amphibious transport design were built.

• Anti-submarine helicopter • In service for 30 years

As a true rotorcraft pioneer, Sikorsky was quick to realise the potential of the helicopter for anti-submarine warfare (ASW) operations. With its HSS-1 Sea Bat already in service, Sikorsky designed the HSS-2 Sea King as its turbine- engined replacement. The company could not have realised that the Sea King would become one of the world’s most important helicopters, in service with the US Navy (USN) and many export customers.

Dual-role helicopter ►

In the early /970s tho USN needed a helicopter to perform both plane guard and ASW duties aboard its attack earners and tho SH-3 proved ideal.

▼ Enduring design

Despite being in servico for nearly 40 years, the outward appearance of the S-61 has surprisingly changed very little, though the latost versions arc considerably more capable than early variants.

FACTS AND FIGURES

► Sea Kings wero heavily involved in Vietnam, rescuing many downed USN pilots during the long contlict.

► A small number of RH-ЗА minesweeper variants entered servico in 1964.

► Tho Royal Canadian Navy was the first export customer, ordortng 41 of the type.

>• Acronautiche Giovanni Agusta acquired a licence to assemble Sea Kings for the Italian air forco and navy.

► Argentina is unique in that it operates both Sikorsky and Agusta built examples.

► The SH-3 has been replaced by aboard USN carriers by the SH-60F Sea Hawk.

To an imperilled survivor of a sea disaster, no gift could seem more heavenly than an S-61 helicopter lowering its survival hoist. A quantum leap in helicopter design, the long-serving S-61 Sea King has been a diligent labourer at many civil and military tasks. But no-one appreciates this superb helicopter more than the thousands around the world who are alive today because of an S-61 rescue.

◄ Pilot rescue

The Belgian air force is one ot many that usos the Sea King to snatch its downed pilots from the sea after they have ditched. Belgian Sea Kings arc kept busy, working in the crowded Channel shipping lanos.

A Oilrig supply

The S-61 has been a very popular oilng helicopter in the North Sea. Its twin engines and all-weather capability are essential in this work.

Sikorsky

• ASW/utility helicopter • US Army, Navy and Marines • Piston engine

Anew generation of helicopter design was ushered in by Sikorsky’s S-58. Prior to its first flight in 1954, helicopters had been built for their unique capabilities, with little thought given to their role suitability. The S-58, operated by the US Navy, Marines and Army, was a highly versatile helicopter suited to a variety of roles. It went on to win many export orders in both military and commercial versions and a few still remain in service.

◄ Bullpup shot

Several experiments were earned out with armed H-34s, but none entered service. This Mannos HUS-1 makes an early test firing.

FACTS AND FIGURES

► When he checked in for e Sabena S-58 flight, Igor Sikorsky was asked if his name was spelt like the helicopter‘s.

► US military designation changes in 1962 led to tho HSS-1 becoming the SH-34G.

► ‘Doughnut’ bags could bo fixed to tho S-58 undercarriage to make it amphibious.

► US Army CH-34s maintained a constant patrol along the border of West Germany with Czechoslovakia and East Germany.

► The US Army-Marines Executive Flight Detachment used VH-34D aircraft.

>■ A total of 603 S-58s woro delivered to tho US Marines.

• US Army and Marines transport • First twin-engined Sikorsky

For 10 years after its first flight the S-56 was the largest helicopter flying outside the Soviet Union and, until the end of 1961, it was the largest helicopter operated by the US military. Designed to meet a US Navy and Marine Corps requirement for an assault transport, it was also the first twin-engined Sikorsky design. Designated HR2S by the Navy, the S-56 flew in 1953. It served in larger numbers with the US Army as the H-37 Mojave.

▼ Retractable landing gear

Mojaves were not only novel in their engine arrangement; they also had a retractable undercarriage. The main gear assemblies rotractod rearwards into the engine nacelle. Each leg was supported by twin wheels.

◄ On exercises in Puerto Rico

HR2S- Is of HMR-461 touch down at a marked landing area during exorcises.

▼ YH-37 for the Army

In >954, the US Army tested a pro-production XHR2S-1 as a YH-37.

FACTS AND FIGURES

► Mojnvos wore replaced by the CH-54 Tarhe, which welghod loss but could lift five times as much cargo as tho CH-37.

► In all, 150 S-56s wero built; a prototype, 55 for tho USMC and 94 for the Army.

► 1959 saw tho first overseas H-37 deployment, by the Army to Germany.

► Army H-37 As entered service with the 4th Medium Helicopter Transportation Company In February 1958.

► Tho H-37 A had a fuselage capacity large enough to hold three Army Jeeps.

► Tho Army briofly evaluated one of the two HR2S-1 Ws in ‘Arctic’ colours.
