Ministry of Defence

The hon. Gentleman answers his own question in a way. He asked for, and supports, a fiscally open defence modernisation programme. That will pose the question as to whether we want A variants or B variants of the F-35s. The study needs to be done. On the individual cost, he knows from his own experience that it will vary, as the cost of prototypes does. There was not a unit cost for the F-16 because it was a prototype. It is very difficult to pinpoint the exact cost because the life cycles, the upgrades and the weapons systems that would be put on board vary. That is why we cannot provide the exact figure that he is seeking.
