On October 27, the Royal Australian Navy (RAN) commissioned its second Hobart-class air warfare destroyer, HMAS Brisbane (DDG 41). Brisbane is the second vessel in the RAN’s three-ship program to replace its fleet of Adelaide-class guided-missile frigates, the first being HMAS Hobart (DDG 39), commissioned in September 2017. Equipped with the Aegis Combat System, the vessel will employ the AN/SPY-1D(V) phased array radar and the AN/SPQ-9B surface search radar. It will also be armed with SM-2 interceptors and the Evolved Seasparrow Missile (ESSM). HMAS Brisbane will be tested and evaluated under Commander Josh Wilson before being integrated into the fleet.
