HMAS_Protector_(ASR_241)
HMAS Protector (ASR 241) was a Royal Australian Navy (RAN) trials and submarine rescue ship. Built in 1984, the ship was initially operated by the National Safety Council of Australia as MV Blue Nabilla. She was purchased by the RAN in 1990 for use as a surveillance, training, and diving support vessel. During her military career, Protector supported the trials of the Collins-class submarines, and was involved in a search for the shipwreck of the World War II cruiser HMAS Sydney. The ship was decommissioned in 1998 and, while still owned by the Commonwealth, she is provided to Defence Maritime Services to allow them to support Navy activities under contract. Renamed Seahorse Horizon, the ship is operated by Defence Maritime Services out of HMAS Creswell as a training and Fleet support vessel.
