[3] The LCHs have a maximum payload of 180 tons; equivalent to three Leopard 1 or two M1A1 Abrams tanks, 13 M113 armored personnel carriers, 23 quarter-tonne trucks, or four LARC-V amphibious cargo vehicles.
[3] The flat, box-like keel causes the ships to roll considerably in other-than-calm conditions, limiting their ability to make long voyages.
[4] The LCHs can mate their bow ramp to the stern loading dock of the RAN's large amphibious warfare ships when operating in the ship-to-shore role.
[7] All were laid down during 1971 and 1972, with lead ship Balikpapan entering service with the Australian Army Water Transport Squadron at the end of 1971.
[7][8] In January 1973, the Balikpapans in RAN service were formed together as the First Australian Landing Craft Squadron, based at HMAS Moreton in Brisbane.
[4] In November 1974, Salamaua and Buna were transferred to the fledgling Papua New Guinea Defence Force, along with five Attack-class patrol boats.
[4][9] Five of the remaining Australian LCHs were deployed in December 1974 following Cyclone Tracy as part of Operation Navy Help Darwin; HMAS Labuan was undergoing refits at the time.
[10] HMAS Labuan was assigned to the Royal Australian Navy Reserve in June 1979, and attached to the Brisbane Port Division.
[3] On entering service, Brunei and Betano initially supplemented the inshore hydrographic survey capabilities of the RAN until late 1988, when they were reassigned to the naval base HMAS Waterhen for use in diver training.
[3] During May and June 1984, Balikpapan completed a 5,400-nautical-mile (10,000 km; 6,200 mi) transit from Brisbane to Penang, transporting vehicles, equipment, and personnel to RAAF Butterworth; the longest ocean voyage undertaken by a vessel of this class.
[20] Labuan and Tarakan delivered humanitarian supplies to remote coastal settlements in the Solomon Islands in September 2014 as part of Australian support efforts in the region.
[21] After decommissioning from Australian service, Labuan was transferred to the PNGDF for use as a training vessel, and was commissioned as HMPNGS Lakekamu on 4 December 2014.
[29] The two landing craft sailed that day for the Philippines, with a formal christening ceremony to be held following their arrival in early August.
