HMAS Attack (P 90) was the lead ship of the Attack-class patrol boats used by the Royal Australian Navy (RAN). Launched in April 1967 and commissioned in November that year, the ship was largely commercial in design and was used to protect fisheries in Australia's northern waters, and to support the survey ship Moresby. The vessel remained in RAN service until 1985 when it was transferred to the Indonesian Navy and renamed Sikuda.
