HMAS Warrnambool (FCPB 204)

HMAS Warrnambool (FCPB 204), named after the city of Warrnambool, Victoria, was a Fremantle class patrol boat of the Royal Australian Navy (RAN).

Design and construction
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. The Fremantles had a full load displacement of 220 t, were 137.6 ft long overall, had a beam of 24.25 ft, and a maximum draught of 5.75 ft. Main propulsion machinery consisted of two MTU series 538 diesel engines, which supplied 3200 shp to the two propeller shafts. Exhaust was not expelled through a funnel, like most ships, but through vents below the waterline. The patrol boat could reach a maximum speed of 30 kn, and had a maximum range of 5000 nmi at 5 kn. The ship's company consisted of 22 personnel. 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, although the mortar was removed from all ships sometime in the late 90s. 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.

Warrnambool was built by North Queensland Engineers and Agents.

Fate
Warnambool was decommissioned in 2005.
