Design and construction

Leeuwin has a displacement of 2,170 tons at full load. [1] 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). [1] Main propulsion machinery consists of four GEC Alsthom 6RK 215 diesel generators, which supply two Alsthom electric motors, each driving a propeller shaft. [1] A Schottel bow thruster is fitted for additional manoeuvrability. [1] Maximum speed is 13 knots (24 km/h; 15 mph), with a range of 18,000 nautical miles (33,000 km; 21,000 mi) at 9 knots (17 km/h; 10 mph). [1]

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. [1] The sonars and echo sounders allow the vessels to chart waters up to 6,000 metres (20,000 ft) deep. [2] There are three sets of davits fitted to carry Fantome-class survey boats. [1] The ship is fitted with a helicopter deck, previously for an AS 350B Squirrel helicopter detached from 723 Squadron, although there are no long-term hosting facilities. [1] She is armed with two single 12.7 mm machine guns. [2] The ship's company consists of 10 officers and 46 sailors, plus up to 5 trainees. [1] The Leeuwin class were the first RAN ships to use a multi-crewing concept,[ citation needed ] with three complements used to operate the two vessels. [2]

Leeuwin was ordered from NQEA Australia on 2 April 1996, and built at the company's shipyard in Cairns. [1] She was laid down on 9 May 1997 and launched on 23 June 1998. [2] Leeuwin and sister ship Melville underwent a joint commissioning ceremony on 27 May 2000. [1] Leeuwin initially carried the pennant number "HS 01", but this was changed to "A 245" in 2004. [2] She is named after Cape Leeuwin, the south-west-most point of the Australian continent.

Operational history

In late 2001, Leeuwin began to operate in support of border protection operations in addition to her normal hydrographic duties. [2] [3] In January 2002, Leeuwin was repainted from white to grey. [2] [3]

In October 2013, Leeuwin participated in the International Fleet Review 2013 in Sydney. [4] The fleet was reviewed by Governor-General Quentin Bryce on 5 October from Leeuwin's helicopter deck, with Bryce accompanied by Prince Harry. [5]

Leeuwin sailed to Fiji in July 2015 for a seabed-mapping operation around Rotuma Island. [6] This was the first RAN deployment to the region in eight years, since the deterioration of ties between the nations after the 2006 Fijian coup d'état. [6]
