What would a British fast battleship designed in 1950 look like?
Short answerLikely 16-inch guns, over 30 knots, and a displacement somewhat greater than Vanguard.
NotesWith the Iowa class available, interoperability becomes a central design driver. Britain would gain practical advantages by sharing a gun caliber with its principal ally. The ship would also need enough speed to operate with modern carrier and fast-battleship groups.
