Kanimbla-class landing platform amphibious

The Kanimbla class was a class of amphibious transport ships (designated Landing Platform Amphibious) operated by the Royal Australian Navy (RAN). Two ships (originally built as Newport-class tank landing ships for the United States Navy) were purchased by Australia in 1994 and modified. Problems during the handover process and the need to repair previously unidentified defects meant the ships did not enter operational service until the end of the decade.

Between them, the two ships have deployed to the Solomon Islands in 2000–01, Vanuatu in 2001, and participated in the Afghanistan and Iraq wars, the Australian response to the 2004 Indian Ocean tsunami, the Australian deployment to East Timor following the 2006 political crisis, and Operation Quickstep off Fiji.

After a large number of defects were found in both ships during late 2010, the vessels were docked. It was decided that Manoora was beyond economic repair, and she was decommissioned in May 2011. Kanimbla was to be repaired and returned to service, but the estimated cost and time to do this, plus the successful acquisition of the British landing ship dock RFA Largs Bay as an interim capability replacement, prompted the government to decommission Kanimbla in November 2011. Both ships were sold in 2013 and broken up for scrap.

The two ships were based at Fleet Base East. The Kanimblas operated primarily in South East Asian regions, and were usually the first asset deployed by the Australian government during regional emergencies. Both ships deployed to the Solomon Islands in 2000–01 in support of operations there, while Kanbimbla took part in disaster relief operations in Vanuatu in 2001. They have since participated in the Afghanistan and Iraq wars, the Australian response to the 2004 Indian Ocean tsunami, and the Australian deployment to East Timor following the 2006 poilitical crisis, among other deployments. Two helicopters have crashed while operating from Kanimbla; a Sea King which crashed off the island of Nias in Indonesia on 2 April 2005 killing nine personnel, and an S-70A Blackhawk helicopter which crashed in international waters off Fiji on 29 November 2006 during Operation Quickstep, killing the pilot and a trooper from the Special Air Service Regiment.

In late September 2010, both ships were brought to Fleet Base East for an 'operational pause' after several problems were identified with the ships. These included large quantities of corrosion, faults with the deck crane and alarm system, the need to overhaul propulsion machinery, power generators, and air conditioning, and an outdated communication suite. The problems have been attributed to the ship's high operational tempo, delays in maintenance, and the age of the ships. On 1 November it was reported that the two vessels might never put to sea again due to their poor condition, but a Navy spokesman was quoted the next day as saying that they would both be repaired by early 2011.

On 1 February 2011 the Minister for Defence announced that repairing Manoora would not be cost effective given that the ship was scheduled to retired at the end of 2012 and that she would instead be decommissioned. Manoora was decommissioned at Fleet Base East on 27 May 2011. At the time of the February 2010 announcement, the intention was to repair Kanimbla return her to active service by mid-2012, and let her continue operating until her original 2014 decommissioning date. However, the predicted time frame and cost of the repairs (18 months and over $35 million), and the successful acquisition of the British landing ship dock RFA Largs Bay (which entered RAN service at the end of 2011 as HMAS Choules) prompted the Australian government to announce plans on 18 August 2011 to decommission Kanimbla at earliest opportunity. Kanimbla was decommissioned on 25 November 2011.
