HMPNGS Buna is a Balikpapan-class heavy landing craft operated by the Papua New Guinea Defence Force (PNGDF). Prior to 1974, the vessel was called HMAS Buna (L 132) and was operated by the Royal Australian Navy (RAN).
Design and construction
[edit]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 GM 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][4] 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 laid down by Walkers Limited at Maryborough, Queensland on 31 July 1972, launched on 26 September 1972, and commissioned into the RAN on 7 December 1973.[5]
Operational history
[edit]In April 1974, Buna, Betano, and Brunei transited to Lord Howe Island as a demonstration of the Balikpanan class' oceangoing capabilities.[6]
On 14 November 1974, Buna was decommissioned from RAN service and transferred to the Papua New Guinea Defence Force.[7] In June 2021, Buna was decommissioned from PNGDF service.[8]
