Following the 1966 Defence White Paper, the Air Ministry decided on two aircraft: the F-111K, with a longer-term replacement being a joint Anglo-French project for a variable geometry strike aircraft – the Anglo French Variable Geometry Aircraft (AFVG). A censure debate followed on 1 May 1967, in which Healey claimed the cost of the TSR-2 would have been £1,700 million over 15 years including running costs, compared with £1,000 million for the F-111K/AFVG combination. Although 10 F-111Ks were ordered in April 1966 with an additional order for 40 in April 1967, the F-111 programme suffered enormous cost escalation coupled with the devaluation of the pound, far exceeding that of the TSR-2 projection. Many technical problems were still unresolved before successful operational deployment and, faced with poorer-than-projected performance estimates, the order for 50 F-111Ks for the RAF was eventually cancelled in January 1968.
