HMAS Launceston (ACPB 94) is an Armidale-class patrol boat of the Royal Australian Navy (RAN).

Design and construction

Main article: Armidale-class patrol boat

The Armidale-class patrol boats are 56.8 metres (186 ft) long, with a beam of 9.7 metres (32 ft), a draught of 2.7 metres (8 ft 10 in), and a standard displacement of 270 tons. 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. 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. 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.

The main armament of the Armidale class is a Rafael Typhoon stabilised 25-millimetre (0.98 in) gun mount fitted with an M242 Bushmaster autocannon. Two 12.7-millimetre (0.50 in) machine guns are also carried. Boarding operations are performed by two 7.2-metre (24 ft), waterjet propelled rigid-hulled inflatable boats (RHIBs). Each RHIB is stored in a dedicated cradle and davit, and is capable of operating independently from the patrol boat as it carries its own communications, navigation, and safety equipment.

Each patrol boat has a standard ship's company of 21 personnel, with a maximum of 29. 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. 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. However, a malfunction in the sewerage treatment facilities aboard HMAS Maitland in August 2006 pumped hydrogen sulphide 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.

Launceston was constructed by Austal at their shipyard in Henderson, Western Australia. She was commissioned in Launceston, Tasmania on 22 September 2007.

Operational history

She is based in Cairns and performs border protection and fisheries protection patrols.

Launceston was used for pick-up filming during the creation of the second season of Australian drama series Sea Patrol in 2008. The footage was conflated with the main footage of sister ship Broome to create the fictional HMAS Hammersley, the ship the series is set on.
