Design and construction
The Attack class was ordered in 1964 to operate in Australian waters as patrol boats, based on lessons learned through using the Ton-class minesweepers on patrols around Borneo during the Indonesia-Malaysia Confrontation, and to replace a variety of old patrol, search-and-rescue, and general-purpose craft. Initially, nine were ordered for the RAN, with another five for Papua New Guinea's Australian-run coastal security force, although another six ships were ordered to bring the class to twenty vessels. The patrol boats had a displacement of 100 tons at standard load and 146 tons at full load, were 107.6 feet (32.8 m) in length overall, had a beam of 20 feet (6.1 m), and draughts of 6.4 feet (2.0 m) at standard load, and 7.3 feet (2.2 m) at full load. Their propulsion machinery consisted of two 16-cylinder Paxman YJCM diesel engines, which supplied 3,460 shaft horsepower (2,580 kW) to the two propellers. The vessels could achieve a top speed of 24 knots (44 km/h; 28 mph), and had a range of 1,200 nautical miles (2,200 km; 1,400 mi) at 13 knots (24 km/h; 15 mph). The ship's company consisted of three officers and sixteen sailors. The main armament was a bow-mounted Bofors 40 mm gun, which was supplemented by two .50 calibre M2 Browning machine guns and various small arms. The ships were designed with as many commercial components as possible: the Attacks were to operate in remote regions of Australia and New Guinea, and a town's hardware store would be more accessible than home base in a mechanical emergency.
Adroit paid off on 28 March 1992. The patrol boat was sunk as a target by A-4 Skyhawk aircraft of No. 2 Squadron RNZAF on 8 August 1994. The wreck is located in the Rottnest ship graveyard, west of Rottnest Island.
