What USAF Intelligence Filed About TSR-2 Performance Data — The Aircraft They Helped Cancel

The complete declassified history of what United States Air Force intelligence actually filed about the British Aircraft Corporation TSR-two — the most advanced tactical strike aircraft of the nineteen sixties, and the aeroplane the Pentagon helped Harold Wilson's Labour government cancel in April nineteen sixty-five. Drawing on Foreign Technology Division case files released at College Park, Cabinet Office papers from the National Archives at Kew, the Healey papers at Churchill College Cambridge, and the Defence Intelligence Agency final assessment of November nineteen sixty-six, this documentary examines the parallel American intelligence operation that ran alongside the F-one-eleven sales effort. From Lieutenant Colonel Sturgis's first cable from Warton to the destruction of the production tooling at Samlesbury, this is the technical and political story of a British aircraft that exceeded its specifications and was cancelled anyway. Featuring Bristol Siddeley Olympus Twenty-Two R engine telemetry, Ferranti AIRPASS terrain-following radar performance, the Elliott Verdan computer technology transfer, and the Treasury memorandum that sealed the programme's fate. Cold War aviation history, RAF history, British defence procurement, McNamara Pentagon, Wilson government, TSR-2 cancellation, F-111K, Anglo-American defence relations.
