HMAS Bombard (P 99) was an Attack-class patrol boat of the Royal Australian Navy (RAN).

Design and construction[edit]

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 of Borneo during the Indonesia-Malaysia Confrontation, and to replace a variety of old patrol, search-and-rescue, and general-purpose craft.[1] 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.[1] 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.[1][2] Propulsion machinery consisted of two 16-cylinder Paxman YJCM diesel engines, which supplied 3,460 shaft horsepower (2,580 kW) to the two propellers.[1][2] 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).[1][2] The ship's company consisted of three officers and sixteen sailors.[2] Main armament was a bow-mounted Bofors 40 mm gun, supplemented by two .50-calibre M2 Browning machine guns and various small arms.[1][2] 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.[3]

Bombard was built by Walkers Limited at Maryborough, Queensland,[4] launched on 6 July 1968,[citation needed] and commissioned on 5 November 1968.[4]

Operational history[edit]

During 1978 and 1979, Bombard was one of two Attack-class vessels used to portray the fictional HMAS Ambush for ABC drama series Patrol Boat.[1] For this, Bombard's pennant number was changed to 83, to match the other patrol boat used, HMAS Advance.[1]

Bombard paid off on 12[citation needed] September 1983, was transferred to the Indonesian Navy and renamed KRI Siribua.[1][5] The patrol boat was listed in Jane's Fighting Ships as still operational in 2011.[5]
