HMAS Arunta (FFH 151) is an Anzac-class frigate serving in the Royal Australian Navy, named after the Arrernte people. Laid down in 1995 at Williamstown, Victoria, and launched in 1996, the vessel was commissioned in 1998. The ship measures approximately 118 meters in overall length, with a waterline length of 109 meters, a beam of 14.8 meters, and a full load displacement of around 3,600 tonnes. Its construction involved assembling six hull modules and six superstructure modules, with modules fabricated in Williamstown and Whangarei, New Zealand, culminating in final integration at Williamstown. Powered by a Combined Diesel or Gas (CODOG) system, Arunta employs a single General Electric LM2500-30 gas turbine generating 30,172 horsepower and two MTU diesel engines producing 8,840 horsepower each. This propulsion allows for a maximum speed of 27 knots and a range exceeding 6,000 nautical miles at 18 knots. The standard crew comprises 22 officers and 141 sailors. Armament includes a 5-inch Mark 45 gun, an eight-cell Mark 41 vertical launch system (VLS) for Sea Sparrow missiles, two 12.7mm machine guns, and two Mark 32 triple torpedo tubes initially firing Mark 46 torpedoes, later upgraded to MU90 Impact torpedoes. The ship is also fitted with plans for additional weapons systems, including Harpoon missile launchers and a Phalanx close-in weapon system, though some were not implemented. Arunta was originally equipped with a Sikorsky S-70B-2 Seahawk helicopter, which was replaced by a Sikorsky MH-60R Seahawk by 2017. Throughout its service, Arunta has engaged in diverse missions, including border protection patrols in northern Australia, and deployments to the Persian Gulf, notably participating in Operation Slipper (2002) and Operation Catalyst (2007–2008). The vessel has been involved in significant events such as intercepting illegal vessels and supporting coalition efforts. In 2014, Arunta underwent a notable upgrade, including the installation of CEAFAR phased array radar and an upgraded combat management system. Its maritime significance is marked by its active role in regional security, sanctions enforcement, and naval operations, maintaining a vital presence in Australia's naval capabilities.
