The planned King George V, Lion, and Vanguard programmes amounted to roughly thirteen new capital ships. They were meant to replace the R class, older Queen Elizabeths, Renown and Repulse, and eventually Hood, although modernized ships might remain while the fleet expanded. This scale explains why the Admiralty preferred mature guns, turrets, hull practice, and machinery over repeated clean-sheet development. Chatfield's support for the 14-inch gun shaped King George V, while Henderson and much of the officer corps favored the 16-inch, triple-turret direction embodied by Lion. The choice of battleship design was also a decision about fleet renewal and institutional priorities.

Lion belonged to a rapid programme intended to replace an ageing battle line, not to a one-off search for the most impressive possible battleship.
