HMAS Brunei (L 127)

HMAS Brunei (L 127) is a Balikpapan class heavy landing craft operated by the Royal Australian Navy (RAN).

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. They are 44.5 m long, with a beam of 10.1 m, and a draught of 1.9 m. The landing craft have a standard displacement of 316 tons, with a full load displacement of 503 tons. 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 kn. The standard ship's company is 13-strong. The Balikpapans are equipped with a Decca RM 916 navigational radar, and fitted with two 7.62 mm machine guns for self-defence.

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. 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. The vessel's payload affects the range: at 175 tons of cargo, each vessel has a range of 1300 nmi, which increases to 2280 nmi with a 150-ton payload, and 3000 nmi when unladen. The flat, box-like keel causes the ships to roll considerably in other-than-calm conditions, limiting their ability to make long voyages.

Brunei was laid down by Walkers Limited at Maryborough, Queensland on 9 August 1971, launched on 8 October 1971, and commissioned on 5 January 1973.

Operational history
In April 1974, Brunei, Buna, and Betano transited to Lord Howe Island as a demonstration of the Balikpanan class' oceangoing capabilities.

Following the destruction of Darwin by Cyclone Tracy during the night of 24-25 December 1974, Brunei was deployed as part of the relief effort; Operation Navy Help Darwin. Brunei sailed from Brisbane on 27 December, and arrived on 13 January 1975.

From 1985 to 1988, Brunei and Betano were assigned to the Australian Hydrographic Officer and operated as survey ships in the waters of northern Australian and Papua New Guinea.

Brunei was deployed to East Timor as part of the Australian-led INTERFET peacekeeping taskforce during 1999 and 2000. She was attached to INTERFET on three occasions; 20 September to 17 November 1999, 8 December 1999 to 15 January 2000, and 15 to 23 February 2000. The ship was later awarded the battle honour "East Timor 1999-2000" for these deployments. Brunei also operated in support of UNTAET between 2000 and 2002.

In 2006, Brunei visited Lord Howe Island for the 75th anniversary of the first solo Australia to New Zealand flight by Sir Francis Chichester.
