HMAS Lachlan (K364/F364) (later HMNZS Lachlan (F364)) was a River-class frigate that served the Royal Australian Navy (RAN) from 1945 to 1949. The vessel was later transferred to the Royal New Zealand Navy serving as surveyor until 1975 and was eventually scrapped in 1993.

Construction and design[]

Lachlan was laid down by Morts Dock and Engineering Company at Balmain, New South Wales on 22 March 1943 and launched on 25 March 1944 by Sarah McNamara Scullin, wife of former Australian Prime Minister James Scullin. The ship was named for the Lachlan River in New South Wales, and commissioned into the RAN on 14 February 1945.^{[citation needed]}

Operational history[]

Australian service[]

During 1945, Lachlan was used during the opening of the Captain Cook Graving Dock; her bow was used to cut the ribbon across the drydock's mouth.^[1]

Lachlan was paid off on 31 May 1949. She was transferred to the Royal New Zealand Navy, renamed HMNZS Lachlan, and served as a survey and Antarctic supply vessel until February 1975. She was used as a "Refit Barge" with many workshops onboard until the late 1980s when she was sold to Chile to continue work as floating workshops for ships being refitted.^{[citation needed]}

New Zealand Service[]

In 1948, the New Zealand government sought for a survey ship to temporarily use until a new one could be constructed in Britain. After negotiations, Lachlan was offered on loan for an initial time of three years and on 31 May 1949 was paid off from RAN service and was immediately given to the Royal New Zealand Navy the next day. Following trials through September 1949, on 5 October 1949 HMNZS Lachlan was commissioned into the Royal New Zealand Navy.^[2]

The ship was fully disarmed at the dockyard at HMNZS Philomel and the ship's chart room enlarged for surveying. The ship was rushed into service so quickly that some of the finishing touches were done at sea. Her first survey was started on 18 November 1949 surveying the Wellington harbour entrance, taking three weeks to complete with assistance of a survey motor boat from Australia. To assist with the creation of the hydrographic service, on earlier voyages part of the ships company included personnel from the Royal Australian Navy and Royal Navy.

HMNZS Lachlan surveyed over fifty percent of New Zealand's coastline over her twenty-years commissioning. Some of her service included surveys in Australia and the rest of the pacific, and she even helped clear mines around the Gilbert & Ellice islands from the Second World War. Her bow was damaged in a collision with the Napier wharf in October 1954. In 1963 the New Zealand government purchased the vessel for 16,000 pounds. By 1970, she was due to be decommissioned but in May 1970 the Royal New Zealand Navy was ordered by the government by an extra five years.

In 1975, HMNZS Lachlan was painted all grey and docked at HMNZS Philomel to house ship's companies whose frigates were undergoing refits. In September 1975, her engines were removed and sold, and in 1993 the hulk of HMNZS Lachlan was sold to a Philippines company for scrapping.
