The Antarctic Survey Vessel (ASV) Wyatt Earp (ASV 01/DMS 329) is a survey launch operated by the Australian Hydrographic Service since 1993. Based on the Royal Australian Navy's Fantome-class survey launches, Wyatt Earp was built specifically for hydrographic survey duties in Antarctic waters.

Design and construction

Wyatt Earp is a smaller version of the Fantome class survey launches used by the Royal Australian Navy, modified for operations in Antarctic waters. [1] The vessel has a full load displacement of 5.77 tonnes (5.68 long tons; 6.36 short tons), is 8.15 metres (26 ft 9 in) long at the waterline and 9.2 metres (30 ft 2 in) in length overall, and has a draught of 0.53 metres (1 ft 9 in). [1] Propulsion is provided by two Volvo Penta AQAD 41D/SP290 diesels, which provide 400 brake horsepower (300 kW) to the two outdrives. [1] Maximum speed is 22.5 knots (41.7 km/h; 25.9 mph), and Wyatt Earp has a range of 306 nautical miles (567 km; 352 mi) at 18 knots (33 km/h; 21 mph). [1] When built, the boat's sensor suite includes a JRC JMA-2141 navigation radar, an STN Atlas Elektronik Deso 22 echo sounder, and a differential GPS receiver. [1] Wyatt Earp has a complement of four to five. [1] [2]

Wyatt Earp was built by Pro Marine at Seaford, Victoria. [1] She entered service in 1993. [1]

Operational history

Wyatt Earp is operated by the Australian Hydrographic Service (AHS). [3] The vessel is not used on a constant basis; her deployment can only occur if a resupply ship chartered by the Australian Antarctic Division is capable of transporting and serving as a base ship to Wyatt Earp and the AHS's Deployable Geospatial Support Team. [3]

The boat was deployed to the Antarctic during 2003 and 2004. [2]

Wyatt Earp was not sent to the Antarctic again until December 2013. [2] During the two-month operation, the survey craft was deployed from Aurora Australis on seven occasions for survey work in the waters around Casey Station. [2]

After being decommissioned she was sold to civilian operators in Britain in 1998 for conversion to a cruise ship, but was found unsuitable for the role and eventually sent to Spanish shipbreakers in 2002.

The Arafura class is a multipurpose small warship class for the Royal Australian Navy (RAN). Initially proposed in the 2009 Defence White Paper and marked as procurement project SEA 1180, It was originally planned 20 Offshore Combatant Vessels would replace 26 vessels across four separate ship classes: the Armidale-class patrol boats, the Huon-class minehunters, the Leeuwin-class survey vessels, and the Paluma-class survey motor launches. Although having a common design, the ships would use a modular mission payload system to fulfill specific roles; primarily border patrol, mine warfare, and hydrographic survey. The 2013 Defence White Paper committed to the OCV project as a long-term goal, but opted in the short term for an accelerated procurement of an existing design to replace the Armidales, and life-extension refits for the other types. This resulted in the Offshore Patrol Vessel project and the amount of vessels reduced to 12. However, this was further increased to 14 when 2 further Mine Counter Measures variants were proposed under SEA 1905.

They are fitted with navigational and survey equipment and are unarmed.
