Hobart-class Guided Missile Destroyer

The Hobart-class Guided Missile Destroyer is a class of warship designed to replace the decommissioned Perth-class destroyers in the RAN. The Hobart is based on the Spanish Álvaro de Bazán-class guided missile frigate. Although the designation "Air Warfare Destroyer" is used to describe ships dedicated to the defence of a naval force (plus assets ashore) from aircraft and missile attack, the planned Australian destroyers would also be able to operate in anti-surface, anti-submarine, and naval gunfire support roles. The Hobart was launched in mid 2006 and commissioned in late 2007. The remaining three ships would enter service from mid 2008 through early 2011.
