The Hobart class Guided Missile Cruisers are American-designed, Australian-built AEGIS equipped Air Warfare Cruisers in service with the Royal Australian Navy. They are made by the Australian Submarine Corporation, in South Australia. The design is based on the American Arleigh Burke class Guided Missile Destroyers but enlarged to 10,000 tonnes. Three are named for Australian capital cities, and the last for the Leander class cruiser HMNZS Achilles, which was the first New Zealand ship to enjoy success in battle.

The ships are among the most powerful surface combatants in the world, having 128 Mk-41 VLS cells for Standard missiles, VL-ASROC, Tomahawk cruise missiles, and Evolved Sea Sparrow Missiles (rarely carried). The ship also carries 16 Harpoon missiles in quad launchers.

A relative of the Hobart class cruiser is the Battle class destroyer, which is another Arleigh Burke derivative, but in this case scaled down to 8,100 tonnes.

There are four in service:

• HMAS Hobart
• HMAS Brisbane
• HMAS Darwin
• HMAS Achilles
