Were the Queen Elizabeth-class carrier plans finalized before the F-35B program was under way?
Short answerNo. The carrier and aircraft programs developed over broadly the same long period.
NotesBritain did not complete its carrier plans and only then select the F-35B. The Queen Elizabeth class and the short-takeoff fighter were parallel, long-duration projects. Choices about the ships and their aircraft therefore cannot be separated into two neatly consecutive procurement decisions.
