trv

TRV Tuna (801) was one of three Torpedo Recovery Vessels operated by the Royal Australian Navy (RAN) and Defence Maritime Services (DMS). Ordered in 1969, the vessel, originally identified as TRV 253, was completed in 1970 and assigned to the torpedo firing range at Jervis Bay. The ship received a name and the pennant number "TRV 801" in 1983. In 1988, the three vessels were sold to DMS. Tuna was assigned to the naval base at HMAS Creswell in Jervis Bay. Tuna was active in DMS service as of 2007.
