Starting in the late 1960s, planning began for a new class of patrol boat to replace the Attack class, with designs calling for improved seakeeping capability, and updated weapons and equipment.[1] The Fremantles had a full load displacement of 220 tonnes (220 long tons; 240 short tons), were 137.6 feet (41.9 m) long overall, had a beam of 24.25 feet (7.39 m), and a maximum draught of 5.75 feet (1.75 m).[2] Main propulsion machinery consisted of two MTU series 538 diesel engines, which supplied 3,200 shaft horsepower (2,400 kW) to the two propeller shafts.[2] Exhaust was not expelled through a funnel, like most ships, but through vents below the waterline.[3] The patrol boat could reach a maximum speed of 30 knots (56 km/h; 35 mph), and had a maximum range of 5,000 nautical miles (9,300 km; 5,800 mi) at 5 knots (9.3 km/h; 5.8 mph).[2] The ship's company consisted of 22 personnel.[2] Each patrol boat was armed with a single 40 mm Bofors gun as main armament, supplemented by two .50 cal Browning machineguns and an 81-mm mortar,[2] although the mortar was removed from all ships sometime after 1988. The main weapon was originally to be two 30-mm guns on a twin-mount, but the reconditioned Bofors were selected to keep costs down; provision was made to install an updated weapon later in the class' service life, but this did not eventuate.[4][3]
Whyalla was built by North Queensland Engineers and Agents, in Cairns, Queensland.[2]
Whyalla was based at HMAS Cairns, and was decommissioned on 2 September 2005.[5] She was scrapped in Darwin.
