An established fast-battleship class would change the case for ordering the historical Admiral class. If the R class already retains high speed, perhaps through triple 15-inch turrets that reduce cost, Fisher could no longer justify cancelling those battleships and turning them into battlecruisers on speed grounds alone. His large light cruisers could face stronger resistance for similar reasons. A request for 32 knots would have to justify the extra speed against the protection already available in the fast battleships. Fisher's freedom of action would narrow, and further fast battleships become the expected successor path.

Fast battleships weaken the case for battlecruiser successors
An established fast battle line could limit Fisher's arguments for replacing battleships with battlecruisers.
