Commissioned on 18 May 2020, HMAS Sydney (V) is the last of 3 ships of the Hobart Class guided missile destroyers (DDG). Hobart Class DDGs are based on the Navantia-designed F100 frigate and fitted with the Aegis Combat System. The Air Warfare Destroyer Alliance constructed the ships in Australia.
The Hobart Class provides air defence for accompanying ships, land forces and infrastructure in coastal areas, and for self-protection against missiles and aircraft. The Aegis Combat System, incorporating the state-of-the-art phased array radar and the SM-2 missile, provides an advanced air defence system capable of engaging enemy aircraft and missiles at ranges in excess of 150 km.
The Hobart Class carries a helicopter for surveillance and response to support key warfare areas. The surface warfare function includes long-range anti-ship missiles and a naval gun capable of firing extended range munitions in support of land forces.
The Hobart Class also conducts undersea warfare and is equipped with modern sonar systems, decoys, surface-launched torpedoes and an array of effective close-in defensive weapons.
