The HMAS Sydney, Hobart Class guided missile destroyer passed the tests and now joins her sister ships Hobart and Brisbane as being ready for operational deployment.

Commanding Officer Sydney Commander Andrew Hough said Navy’s Hobart-class destroyers provided significant combat capability to the joint force, be it in defending naval task groups, providing fire support to troops ashore, or coordinating air defense activities with the Air Force.

Built in Adelaide by the Air Warfare Destroyer Alliance, Hobart, Brisbane and Sydney are equipped with the Aegis combat system, which includes advanced phased array radar and SM–2 missiles. The Aegis provides the destroyers with advanced air defense systems capable of engaging aircraft and missiles.

Coupled with its surface and anti-submarine warfare capabilities, the HMAS Sydney destroyer has layered offensive and defensive systems to counter conventional and asymmetric threats in all spheres of naval warfare.
