Royal Australian Navy Air Warfare Destroyer Hobart Sea Trials
Today, the Air Warfare Destroyer Alliance achieved a major milestone with the successful completion of Builder Sea Trials for the first destroyer Hobart following several days at sea off the coast of South Australia. The Hobart class is a ship class of three air warfare destroyers (AWDs) being built for the Royal Australian Navy (RAN). Planning for ships to replace the Adelaide-class frigates and restore the capability last exhibited by the Perth-class destroyers began by 2000, initially under acquisition project SEA 1400, which was redesignated SEA 4000. 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 are expected to also operate in anti-surface, anti-submarine, and naval gunfire support roles. Planning for the Australian Air Warfare Destroyer (as the class was known until 2006) continued through the mid-2000s,
