The TSR2's intended replacement—the American General Dynamics F-111 Aardvark—was shelved on 16 January 1968 when its costs overshot the UK's budget (it would have cost £425m for 50 aircraft). The TSR2 had large development costs, whereas the F-111 (also known as Tactical Fighter Experimental, or TFX) could be bought off the shelf. Coningsby was planned to get the General Dynamics F-111K, the RAF version of the F-111; also in the 1966 Defence White Paper, it was intended that the Anglo-French AFVG, later the UKVG, would replace the TSR2 (it did eventually as the Tornado). 50 F-111Ks were planned with 100 AFVGs (to enter service by 1970); Denis Healey claimed the F-111s and AFVGs would be cheaper than the TSR2 programme (158 aircraft) by £700m. As Minister of Aviation throughout 1965, the Labour MP Roy Jenkins had also wanted to similarly cancel the Olympus-powered Concorde, but the 1962 Anglo-French treaty imposed prohibitively steep financial penalties for cancellation; the Hawker Siddeley P.1154 and HS.681 were cancelled at the same time.
