The Attack-class patrol boats were small coastal defence vessels built for the Royal Australian Navy (RAN) and operated between 1967 and at least 1991.

Twenty boats were ordered by the Department of Defence in November 1965[1] at a cost of around A$800,000[citation needed] each from two Queensland shipyards, Evans Deakin in Brisbane and Walkers in Maryborough.

[citation needed] Acute, Archer, Assail, Attack, Barbette, Bandolier, Barricade, and Bombard were transferred to the Indonesian Navy between 1974 and 1985, and are listed in Jane's Fighting Ships as still operational in 2011.

[citation needed] Adroit paid off on 28 March 1992 and was sunk as a target by A-4 Skyhawk aircraft of the Royal New Zealand Air Force west of Rottnest Island on 8 August 1994.

The 1998 edition of Jane's Fighting Ships reports that two vessels of a similar design, pennant numbers 860 and 861 (KRI Waigeo), were being operated by the Indonesian Navy.
