Would a 15-inch Vanguard class still be built if the N3 and G3 classes existed?
Short answerNo. A 15-inch Vanguard class is rejected if the N3 and G3 designs have been built, regardless of its displacement.
NotesCompleting N3 and G3 rules out a later 15-inch Vanguard class in this assessment. Changing Vanguard's proposed weight or tonnage would not alter that conclusion.
