What if HMS Indomitable replaced Prince of Wales in Force Z?
Short answerPrince of Wales is assumed to ground instead, so Indomitable deploys with the faster Repulse and gives Force Z organic fighters, reconnaissance, and strike aircraft.
NotesThe scenario assumes that Prince of Wales grounds while Indomitable completes her deployment. Repulse remains because she is a battlecruiser and the proposed substitution removes Force Z's battleship. Her greater speed also suits operations with Indomitable. The resulting force gains organic air defense, reconnaissance, and strike aircraft while retaining a fast surface striking ship.
