The Armidale class patrol boats are 56.8 metres (186 ft) long, with a beam of 9.5 metres (31 ft), a maximum draft of 2.25 metres (7.4 ft), and a displacement of 270 tons.[1][2] The semi-displacement vee hull is fabricated from aluminium alloy, and each vessel is built to a combination of Det Norske Veritas standards for high-speed light craft and RAN requirements.[2] The Armidales can travel at a maximum speed of 25 knots (46 km/h; 29 mph), and are driven by two propeller shafts, each connected to an MTU 16V M70 diesel.[1] The ships have a range of 3,000 nautical miles (5,600 km; 3,500 mi) at 12 knots (22 km/h; 14 mph), allowing them to patrol the waters around the distant territories of Australia, and are designed for standard patrols of 21 days, with a maximum endurance of 42 days.[1][2]
The main armament of the Armidale class is a Rafael Typhoon stabilised 25-millimetre (0.98 in) gun mount fitted with an M242 Bushmaster cannon.[1] Two 12.7-millimetre (0.50 in) machine guns are also carried.[3] Boarding operations are performed by two 7.2-metre (24 ft), waterjet propelled rigid-hulled inflatable boats (RHIBs).[2] Each RHIB is stored in a dedicated cradle and davit, and is capable of operating independanly from the patrol boat as it carries its own communications, navigation, and safety equipment.[2][4]
Each patrol boat has a standard ship's company of 21 personnel, with a maximum of 29.[1][2] The Armidales do not have a permanently assigned ship's company; instead, they are assigned to divisions at a ratio of two vessels to three companies, which rotate through the vessels and allow the Armidales to spend more time at sea, without compromising sailors' rest time or training requirements.[2][5] A 20-berth auxiliary accommodation compartment was included in the design for the transportation of soldiers, illegal fishermen, or unauthorised arrivals; in the latter two cases, the compartment could be secured from the outside.[6] However, a malfunction in the sewerage treatment facilities aboard HMAS Maitland in August 2006 pumped hydrogen sulfide and carbon monoxide into the compartment, non-fatally poisoning four sailors working inside, after which use of the compartment for accommodation was banned across the class.[5][6]
Larrakia was constructed by Austal at their shipyard in Henderson, Western Australia.[1] She was commissioned into the RAN in Darwin, Northern Territory on 10 February 2006.[7] Larrakia is named after the Larrakia Aboriginal peoples,[7] and is the only Armidale not to be named after a regional city.
Larrakia is assigned to Attack Division, is based in Darwin, and performs border protection and fisheries protection patrols.
