The Royal Australian Navy's (RAN) newest air warfare destroyer (AWD) NUSHIP Brisbane has started its first phase of sea trials.
NUSHIP Brisbane is the second of three Hobart-class guided missile destroyers being developed under the AWD program in Australia.
Its sister ships are HMAS Hobart and HMAS Sydney. HMAS Hobart was commissioned in September.
This first phase of trials will test the ship's hull, propulsion, manoeuvring, control and navigation systems.
The advanced trials will help demonstrate the capabilities of NUSHIP Brisbane's combat and communications systems.
The AWD alliance, which includes ASC Shipbuilding, the Department of Defence, Raytheon Australia and Navantia, includes more than 60 per cent Australian industry capability.
Brisbane's keel was laid on February 3, 2014 and the vessel was launched on December 15, 2016.
