HMAS Arafura

HMAS Arafura, named to represent Australia's interests in the Arafura Sea, is the lead ship of the Arafura-class offshore patrol vessels currently conducting sea trials for the Royal Australian Navy. The ship is based on the Lürssen OPV80 design, and is being constructed by BAE Systems at the Osborne Naval Shipyard in Osborne, South Australia. It was planned that the ship would enter service in 2022. However, this was significantly delayed due to emerging problems with the seaworthiness of the class and its combat capabilities. As part of a re-design, the originally envisaged OTO Marlin 40 mm main gun was removed and replaced with a 25mm gun taken from the retiring Armidale-class vessels on an planned interim basis. HMAS Arafura was delivered to the navy in February 2025, and commissioned on 28 June 2025.
