The Attack-class patrol boats were small coastal defence vessels built for the Royal Australian Navy (RAN) and operated between 1967 and 1985. Twenty boats were ordered by the Department of Defence in 1965 at a cost of around $AUD 800,000 each from two Queensland shipyards, Evans Deakin in Brisbane and Walkers in Maryborough. The Attack-class ships had a displacement of 146 tons, a crew of up to 25 and were armed with a 40-mm gun, an 81-mm mortar and two 0.50 calibre machine guns. The Attack class was replaced in RAN service by the larger and more capable Fremantle-class patrol boats. Many Attack-class patrol boats were donated to the defence forces of Pacific nations.
