Lockheed TriStar (RAF)
The Lockheed TriStar is an air-to-air tanker and transport aircraft in service with the Royal Air Force. All were converted from civilian Lockheed L-1011-500 TriStar airliners.

Design and development
The Royal Air Force operates nine L-1011-500s TriStars, six ex-British Airways and three ex-Pan Am.[1] The TriStars were bought in the immediate aftermath of the Falklands War to bolster the long range capability of the RAF in the transport and tanker roles, as the demands of refuelling Hercules supporting forces stationed in the Falklands was rapidly using up the fatigue life of the RAF's Victor tankers. A requirement for at least four wide-bodied tanker/transports was drawn up. At the same time, British Airways wanted to get rid off its Lockheed L-1011-500 transports, and so put in a joint bid with Marshall of Cambridge to supply six TriStars.[2] The initial order for the ex-British Airways TriStars placed on 14 December 1982, The three ex-PanAm aircraft were purchased in 1984.[3] All of the aircraft serve with No. 216 Squadron, based at RAF Brize Norton.
Marshall of Cambridge performed the conversion of the TriStars.[1] Two of the aircraft are passenger/tanker aircraft designated TriStar K1s. Another four can operate as either tankers or passenger/cargo aircraft - these are KC1s. Three are pure passenger aircraft; two TriStar C2 and the solitary TriStar C2A. The C2A differs from the C2s in having some military avionics and a new interior.[1]
The RAF's TriStars have been subject to progressive updating, including the fitting of flight deck armour and Directional Infrared Counter Measures to protect against ground fire when flying into Iraq, and under a £22 million contract, are to be fitted with an updated cockpit.[4]
The TriStar is expected to remain in service with the RAF until the end of this decade, when it is scheduled to be replaced by the Airbus A330 MRTT under the Future Strategic Tanker Aircraft (FSTA) program. The Airtanker consortium, led by EADS, won the FSTA contract in January 2004. Beginning in April 2004, there have been continuing rumours about the fragile state of the contract negotiations. With continuing doubts over the FSTA program, Marshall Aerospace offered to buy and convert some of the large number of surplus commercial TriStars as tankers, but this was rejected.[5] This would give the UK a much needed increase in refuelling capacity (with the upcoming retirement of the VC10 fleet) at a fraction of the cost of the £13Bn FSTA project.
Operational history
The aircraft have seen service in many conflicts. Two were deployed to King Khalid International Airport, near Riyadh in Saudi Arabia during the 1991 Gulf War as tankers, with the rest used for transport between the Persian Gulf and UK. The two aircraft deployed received nose art naming them Pinky and Perky. During the 1999 Kosovo War, TriStars deployed to Ancona in Italy, again as tankers, with four aircraft involved. TriStars joined VC10s in the air-to-air refuelling role for Operation Veritas (Afghanistan), during which they provided aerial-refuelling for US Navy aircraft. Their most recent wartime role was again over the skies of Iraq. The RAF deployed four TriStars during Operation Telic, to an as-yet-undisclosed location.Template:Citation needed
