The eight-vessel Balikpapan class was ordered as a locally-manufactured replacement for the Australian Army's LSM-1 class landing ship medium and ALC 50 landing craft.[1] They are 44.5 metres (146 ft) long, with a beam of 10.1 metres (33 ft), and a draught of 1.9 metres (6 ft 3 in).[2] The landing craft have a standard displacement of 316 tons, with a full load displacement of 503 tons.[2] They are propelled by two G.M. Detroit 6-71 diesel motors, providing 675 brake horsepower to the two propeller shafts, allowing the vessels to reach 9 knots (17 km/h; 10 mph).[2] The standard ship's company is 13-strong.[2] The Balikpapans are equipped with a Decca RM 916 navigational radar, and fitted with two 7.62 millimetres (0.300 in) machine guns for self-defence.[2]
The LCHs have a maximum payload of 180 tons; equivalent to 3 Leopard 1 tanks, 13 M113 armored personnel carriers 23 quarter-tonne trucks, or four LARC-V amphibious cargo vehicles.[2][3] As a troop transport, a Balikpapan class vessel can transport up to 400 soldiers between a larger amphibious ship and the shore, or embark 60 soldiers in six-berth caravans for longer voyages.[3] The vessel's payload affects the range: at 175 tons of cargo, each vessel has a range of 1,300 nautical miles (2,400 km; 1,500 mi), which increases to 2,280 nautical miles (4,220 km; 2,620 mi) with a 150-ton payload, and 3,000 nautical miles (5,600 km; 3,500 mi) when unladen.[2] The flat, box-like keel causes the ships to roll considerably in other-than-calm conditions, limiting their ability to make long voyages.[3]
Buna was built by Walkers Limited at Maryborough, Queensland. She was launched on 26 September 1972 and commissioned into the RAN on 7 December 1973.
On 14 November 1974, Buna was decommissioned from RAN service and transferred to the Papua New Guinea Defence Force. She is still in service as of 2008.
