Design and construction

The Attack class was ordered in 1964 to operate in Australian waters as patrol boats (based on lessons learned through using the s on patrols of Borneo during the Indonesia-Malaysia Confrontation, and to replace a variety of old patrol, search-and-rescue, and general-purpose craft. Propulsion machinery consisted of two 16-cylinder Paxman YJCM diesel engines, which supplied to the two propellers.
