Could the Royal Navy have negotiated three smaller carriers instead of two Queen Elizabeth-class ships?
Short answerNo. The authorized package was specifically two British-built, non-nuclear carriers, and changing that bargain risked losing the program rather than gaining a third hull.
NotesThe political specification required two non-nuclear carriers built in Britain. Starting negotiations with a demand for Nimitz-class ships would not have made three smaller hulls available as a compromise. Reopening the requirements risked ending with a perfect design on paper and no ships in service. The completed Queen Elizabeth-class carriers provide a capable force within the British requirements, despite their imperfections.
