Design and Construction
Melville have a displacement of 2,170 tons at full load. She is 71.2 metres (234 ft) long, with a beam of 15.2 metres (50 ft), and a draught of 4.3 metres (14 ft). Main propulsion machinery consists of four GEC Alsthom 6RK 215 diesel generators, which supply two Alsthom electric motors, each driving a propeller shaft. A Schottel bow thruster is fitted for additional manoeuvrability. Maximum speed is 18 knots (33 km/h; 21 mph), with a range of 18,000 nautical miles (33,000 km; 21,000 mi) at 9 knots (17 km/h; 10 mph).
The sensor suite consists of a STN Atlas 9600 APRA I-band navigational radar, a C-Tech CMAS 36/39 hull-mounted sonar, an Atlas Fansweep-20 multibeam echo sounder, an Atlas Hydrographic Deso single-beam echo sounder, and a Klein 2000 towed sonar. The sonars and echo sounders allow the vessels to chart waters up to 6,000 metres (20,000 ft) deep. There are three sets of davits fitted to carry Fantome class survey boats. The ship is fitted with a helicopter deck for a AS 350B Squirrel helicopter (detached from 723 Squadron), although there are no long-term hosting facilities. She is armed with two single 12.7 mm machine guns. The ship's company consists of 10 officers and 46 sailors, plus up to 5 trainees. The Leeuwin class were the first RAN ships to use a multi-crewing concept, with three complements used to operate the two vessels.
Melville was ordered from NQEA on 2 April 1996, and built at the company's shipyard in Cairns, Queensland. She was laid down on 9 May 1997 and launched on 23 June 1998. Melville and sister ship Leeuwin underwent a joint commissioning ceremony on 27 May 2000. Melville initially carried the pennant number "HS 02", but this was changed to "A 246" in 2004. She is named after Melville Island, located to the north of Darwin, Northern Territory.
