The Indefatigable-class battlecruisers of the British Navy are multipurpose vessels designed to outperform German cruisers and make them difficult to operate on strategically important UK shipping routes.
"Indefatigable" was designed on the basis of the project of the battle cruiser "Invincible", which showed sufficient range and speed to intercept enemy raiders. The main difference between Invincible and Indefatigable is only in the location of the middle towers of the main battery. On the new cruiser, they are slightly spaced along the length, to increase the sectors of fire for the main guns. All other parameters: speed, armament, displacement and armor are almost the same.

A total of three ships were built. The lead Indefatigable was launched in October 1909 and entered service in February 1911. Killed by shells from the German battle cruiser Von Der Tann in the Battle of Jutland.
The construction of the other two ships was paid for by the two dominions of the British Empire: Australia and New Zealand.
The battle cruiser Australia, after construction, was to become part of the Australian Navy. Only in the event of a major war could it be transferred to the British Navy, which happened in 1914-18. Until now, it is the largest ship that was in the Australian Navy. On April 12, 1924, it was solemnly flooded, not far from Sydney.
The New Zealand cruiser New Zealand was built on credit. New Zealand settled on it only in 1944. This cruiser was immediately transferred to the British Navy. Best known for traveling around the world in the dominions of the British Empire. He took part in finishing off the German cruiser Blucher at Dogger Bank, and also took part in the Battle of Jutland. Sold for scrap in 1924
