A patrol boat is a relatively small naval vessel generally designed for coastal defence, border protection, immigration law-enforcement, search and rescue duties. There have been many designs for patrol boats. They may be operated by a nation's navy, coast guard, police force or customs and may be intended for marine or estuarine or river environments. They are commonly found engaged in various border protection roles, including anti-smuggling, anti-piracy, fisheries patrols, and immigration law enforcement. They are also often called upon to participate in rescue operations.

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, 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 (OPV) 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.
