Design and construction

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 armoured 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]

Wewak was laid down by Walkers Limited at Maryborough, Queensland on 21 March 1972, launched on 19 May 1972, and commissioned into the RAN on 10 August 1973. [5]

Operational history

Following the destruction of Darwin by Cyclone Tracy during the night of 24–25 December 1974, Wewak was deployed as part of the relief effort; Operation Navy Help Darwin. [6] Wewak was the last of the 13 ships to join the operation; sailing from Brisbane on 2 January 1975, and arriving on 13 January. [6]

Wewak was placed in reserve on 16 August 1985; one of three landing craft decommissioned for economic reasons. [3] [7] She was reactivated in late 2000, but only after lengthy delays, as during the intervening years, she had been used as a parts hulk for the other Balikpapans. [7]

Decommissioning and Fate

Wewak was decommissioned on 11 December 2012. [8]

The Philippine Navy has shown interest in acquiring the ship, after the Australian government donated 2 other sisterships, HMAS Brunei and HMAS Tarakan in 2015. [9] [10] It was later confirmed that the Philippine Navy is acquiring three more LCH from Australia, including ex-HMAS Wewak, at a token price. [11]

HMAS <i>Attack</i> (P 90)

HMAS Attack was the lead ship of the Attack-class patrol boats used by the Royal Australian Navy (RAN). Launched in April 1967 and commissioned in November that year, the ship was largely commercial in design and was used to protect fisheries in Australia's northern waters, and to support the survey ship Moresby. The vessel remained in RAN service until 1985 when it was transferred to the Indonesian Navy and renamed Sikuda.

HMAS <i>Balikpapan</i>

HMAS Balikpapan was the lead ship of the Balikpapan class of heavy landing craft (LCH). Ordered in 1969, Balikpapan entered service with the Australian Army Water Transport Squadron in late 1971. After this, the decision to place all seagoing Army vessels under the control of the Royal Australian Navy (RAN) saw Balikpapan transferred and commissioned in 1974; the last of the eight-vessel class to enter RAN service. Balikpapan was placed in reserve in 1985, but was reactivated three years later. During late 1999 and early 2000, the vessel was part of the INTERFET peacekeeping taskforce, and made additional deployments to East Timor in 2001 and 2006. On 12 December 2012, Balikpapan was retired from RAN service.

<i>Balikpapan</i>-class landing craft heavy In service with the Australian Defence Force and the Papua New Guinea Defence Force

The Balikpapan class is a ship class of eight heavy landing craft. All eight were originally laid down by Walkers Limited for the Australian Army in the early 1970s. A reorganisation of watercraft responsibilities in the Australian military meant the landing craft were to be operated by the Royal Australian Navy (RAN), with seven commissioned directly into RAN service during 1973 and 1974, and lead ship Balikpapan transferred from the army to the navy. During the leadup to the independence of Papua New Guinea in 1975, two of the vessels were transferred to the new Papua New Guinea Defence Force (PNGDF).
