Design and development

Chinook HC1

The Chinook CH-47A entered service with the United States Army in 1962. Following the retirement of the Bristol Belvedere in 1969, also a tandem-rotor design, the RAF required a new heavy-lift helicopter and ordered 33 HC.1s in 1978. These aircraft, which entered service in December 1980, were comparable to the CH-47C, fitted with Lycoming T55-L-11E engines. Eight more HC.1s were delivered from 1984 to 1986 with the CH-47D's Lycoming T55-L-712 turboshafts.

The Bristol Type 192 Belvedere twin-blade helicopter The Bristol Type 192 Belvedere is a twin-engined, tandem rotor helicopter designed for a variety of transport roles including troop transport, supply dropping and casualty evacuation. ...


The replacement of the HC1's metal rotor blades with glass fibre rotors saw these aircraft designated Chinook HC1Bs.


Chinook HC2

The US Army's next generation Chinook, the CH-47D, entered service in 1982. Improvements from the CH-47C included upgraded engines, fibreglass rotor blades, a redesigned cockpit to reduce pilot workload, redundant and improved electrical systems, an advanced flight control system (FCS) and improved avionics. The RAF returned their original HC1s to Boeing for remanufacture to CH-47D standard, the first of which returned to the UK in 1993. Three additional HC.2s were ordered with delivery beginning in 1995.


Six further Chinooks were ordered in 1995 as Chinook HC2As. The main difference in these and the standard HC2 was the strengthening of the front fuselage to allow the fitting of an aerial refueling probe in future. Boom and receptacle: USAF KC-135R Stratotanker, two F-15s (twin fins) and two F-16s, on an aerial refueling training mission IAF Il-76 MD refueling two Mirage 2000 fighter jets German Luftwaffe Airbus A310 MRTT ready for refueling, shown at the Paris Air Show 2007 Aerial refueling, also...


Chinook HC3

Eight Chinook HC3s were ordered in 1995 as dedicated special forces helicopters. By 2007 the helicopters were still to enter service. The procurement was described by the Edward Leigh, then Chairman of the Public Accounts Committee, "as one of the most incompetent procurements of all time."[2] For other uses, see Special forces (disambiguation). ...

The HC3s were to be effectively low-cost variants of the US Army's SF Chinook, the MH-47E. The HC3s would include improved range, night vision sensors and navigation capability. The eight aircraft were to cost £259 million and the forecast in-service date (ISD) was November 1998 (defined as delivery of the first six aircraft). The Boeing CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lift helicopter. ...


Air Forces Monthly reported in November 2006 that The Defence Aviation Repair Agency will likely receive a contract to install the Thales "TopDeck" avionics system on the Chinook HC3s.[3] If and when the HC3s enter service they will join 7 Squadron at RAF Odiham.

The MOD announced in March 2007 that work would begin immediately in converting the helicopters from special forces support to battlefield support helicopters. The programme is estimated to cost £50-60 million and will make the aircraft available within the next 2 years.[4]


Operational history

RAF Chinooks were widely deployed, serving in Operation Corporate (Falklands War). Operation Corporate was the codename given to the 1982 British military involvement in the Falkland Islands during the Falklands War. ... Belligerents Argentina United Kingdom Commanders President Leopoldo Galtieri Vice-Admiral Juan Lombardo Brigadier-General Ernesto Crespo Brigade-General Mario Menéndez Prime Minister Margaret Thatcher Admiral Sir John Fieldhouse Rear-Admiral John “Sandy” Woodward Major-General Jeremy Moore Casualties and losses 649 killed 1,068 wounded 11,313 taken prisoner...


Whilst the RAF has many types of helicopters in active service, the Chinook has proven itself one of the most effective. One particular example, serial ZA718 (Boeing construction number B-849) and also known by its original squadron code 'Bravo November', has seen action in every major operation the RAF has been deployed to in the helicopter's 25-year service life.


Bravo November went to the Falkland Islands in 1982 to spearhead the British landings there along with three other Chinooks. However, the container ship they were being transported on - the Atlantic Conveyor - was attacked on 25 May 1982 by an Argentine Navy Dassault Super Étendard with an Exocet sea-skimming missile. Although the rest of the aircraft were destroyed, Bravo November was airborne on an engineering test flight at the time of the attack. Having survived the destruction of the ship, it managed to make it safely to the aircraft carrier HMS Hermes and was nicknamed The Survivor. The Atlantic Conveyor was a British merchant navy ship that was requisitioned during the Falklands War and sunk by an Exocet missile. ... is the 145th day of the year (146th in leap years) in the Gregorian calendar. ...

Later in the conflict ZA718 ran into trouble during a night mission transporting guns to the SAS when pilot Squadron Leader Dick Langworthy, unable to see clearly through a thick snow shower, hit the sea at around 100 knots (175 km/h) due to a faulty altimeter, throwing up spray and flooding the engine intakes. Fortunately Langworthy and his copilot managed to get the helicopter back in the air. With the radio damaged and unable to navigate, Bravo November returned to San Carlos and a quick inspection revealed the impact had caused little more than dents to the fuselage and damage to the radio systems.

San Carlos is a settlement in northwestern East Falkland, lying south of Port San Carlos on San Carlos Water. ...


ZA718 Bravo November went on to serve in Lebanon, Germany, Northern Ireland, Kurdistan and Iraq, being the first British helicopter to land Royal Marines ashore in Iraq. ZA718 was the first RAF Chinook to be converted to Chinook HC2 standard in 1993/94. Two pilots of ZA718 have been awarded the Distinguished Flying Cross.
