BAC TSR-2
The British Aircraft Corporation TSR-2 was a twinjet strike and reconnaissance aircraft for the RAF.The TSR-2 was designed to penetrate a well-defended forward battle area at low altitudes and very high speeds.Also to provide high-altitude,high-speed stand-off,side-looking radar and photographic imagery and signals intelligence,and aerial reconnaissance.TSR-2 was the victim of ever-rising costs and inter-service squabbling over Britain's future defence needs,which led to the controversial decision to scrap the programme in 1965.
The most advanced aviation technology of the period was incorporated in order to make it the highest-performing aircraft in the world in its projected missions.The USA put tremendous pressure on the UK government to order an adapted version of the General Dynamics F-111,a decision that itself was later rescinded as costs and development times increased.The replacements included the Blackburn Buccaneer and McDonnell Douglas F-4 Phantom II,both of which had previously been considered and rejected early in the TSR-2 procurement process.
Only one of the three airframes flew,and flight tests revealed vibration problems,and issues with the landing gear,but these niggles were soon addressed.Over a period of six months, a total of 24 test flights were conducted.The basic flying qualities of the aircraft which,according to the test pilots involved,were outstanding.Speeds of Mach 1.12 and sustained low-level flights down to 200 ft (above the Pennines) were achieved.The last test flight took place on 31 March 1965.
At two Cabinet meetings held on 1 April 1965,it was decided to cancel the TSR-2 on the grounds of projected cost,and instead to obtain an option agreement to acquire up to 110 F-111 aircraft with no immediate commitment to buy.
The TSR-2 tooling,jigs and many of the part completed aircraft were all scrapped at Brooklands within six months of the cancellation.Two airframes eventually survived: the complete XR220 at the RAF Museum,Cosford and XR222 much less complete at Duxford.The only airframe ever to fly XR219,along with the completed XR221 and part completed XR223 were taken to Shoeburyness and used as targets to test the vulnerability of a modern airframe and systems to gunfire and shrapnel.
The apparent haste with which the project was scrapped has been the source of much argument and bitterness since. The TSR-2, nonetheless, remains a lingering "what if?" of British aviation.
Aeronautical engineer Sir Sydney Camm (designer of the Hawker Hurricane) said of the TSR-2: "All modern aircraft have four dimensions: span, length, height and politics. TSR-2 simply got the first three right."
