The intention was that, by being mounted off centre, one gun in each turret would be able to fire directly ahead or directly astern, thus allowing for at least two guns to be able to point on any bearing. In practice, firing close to the keel line caused significant blast damage to the superstructure, so in reality gunfire was limited to the broadside.

Ajax, and her sister Agamemnon, were the first British battleships to be designed without any sailing rig whatsoever.
