HMS Indefatigable
HMS Indefatigable
Indefatigable class.  Easy to distinguish from the generally similar Invincible class by the arrangement of the wing turrets which now had a funnel between them.  The secondary armament was an improved version of 4 inch gun and none were mounted on the turret roofs.

Enlarged follow on the to the Invincible class.  The extra size was however not used to address any of the weaknesses of the original ships so the armour was similar but distributed differently but in some respects this re-distribution actually made the protection worse.  The armament was similar but the spacing of 'P' and 'Q' turrets was increased to improve cross deck firing arcs.  The last two ships, Australia and New Zealand, were funded by those respective countries and started at a time when the British themselves were building the much superior Lion class.  The relative cheapness of the design appears to have been the reason for this.  The last two ships also gained some extra armour.  Crew 790.
