Arafura-class patrol vessel

The Arafura class is a class of offshore patrol vessels being built 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 that 20 Offshore Combatant Vessels (OCV) 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 (which could be up to 2,000 tonnes in displacement), the ships would use a modular mission payload system to fulfill specific roles; primarily border patrol, mine warfare, and hydrographic survey.
