HMAS Leeuwin (HS 01/A 245) is the lead ship of the Leeuwin-class of hydrographic survey vessels operated by the Royal Australian Navy (RAN).

Design and construction

Main article: Leeuwin-class survey vessel

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 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]}

Leeuwin underway on Sydney Harbour on 5 October 2013

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]
