HMAS Kanimbla (L 51) was a Kanimbla-class amphibious landing platform operated by the Royal Australian Navy, originally built as the USS Saginaw (LST-1188) for the United States Navy. Laid down on 24 May 1969 by the National Steel & Shipbuilding Company in San Diego, California, she was launched on 7 February 1970 and commissioned into the USN on 23 January 1971. Named after the city of Saginaw, Michigan, she was a Newport-class tank landing ship designed for amphibious operations. In the early 1990s, the RAN sought to replace its aging vessels with a purpose-built ship, but the high costs led to the acquisition of surplus US ships instead. Saginaw was decommissioned from the USN on 28 June 1994 and was subsequently sold to Australia, where she was commissioned into the RAN as HMAS Kanimbla on 29 August 1994 after a delay caused by US congressional restrictions. The vessel was then transported to Australia, where she underwent a significant conversion at Forgacs Shipyard in Newcastle. The conversion included removing the bow ramp, welding shut the bow doors, adding a hangar capable of supporting three Sea King or four Blackhawk helicopters, and reinforcing the aft helicopter deck for Chinook operations. The ship’s superstructure was modified to carry two LCM-8 landing craft, with the area serving as a third helicopter landing zone when deployed. Her extensive refit, completed in late 1999 after delays due to corrosion and other issues, cost approximately A$400 million. During her service, Kanimbla participated in numerous deployments worldwide, including the 2003 invasion of Iraq, disaster relief following the 2004 Indian Ocean tsunami, and operations in East Timor and the Solomon Islands. She also supported peacekeeping missions and enforced UN sanctions in the Persian Gulf. Notably, during her service, two helicopters crashed, and she experienced a significant onboard fire in 2010. Kanimbla's operational life ended following a fire in September 2010 and subsequent extensive problems including corrosion and mechanical faults. Despite initial plans to repair her, financial and strategic considerations led to her decommissioning on 25 November 2011. She was later sold for scrapping, and in 2013, she was broken up in New Orleans. Her service history underscores her role as a vital amphibious asset for Australia, participating in key military and humanitarian missions worldwide.
