Was there much consideration of involving the French in British interwar naval exercises?
Short answerThey were considered, but France lacked the exercise budget that allowed the Royal Navy to train at scale.
NotesJoint exercises involving France were suggested during the interwar period. French funding was the obstacle identified here. The Royal Navy, despite its own budget problems, had a dependable allocation for exercises and expected to spend it. That difference mattered to how much training the two navies could undertake.
