The Navy has confirmed it is selling its decommissioned fleet of Sea King helicopters for scrap metal.

Five sea king helicopters have been stored at their former home base of HMAS Albatross in Nowra, south of Sydney, while the Department of Defence decides what to do with them.

They were officially retired in December 2011.

Now it has been confirmed the five choppers, seven engines and spare parts will be sold after 35 years of operations.

One of the sea king helicopters, the Shark 07, will remain at HMAS Alabtross in the base's Fleet Air Arm Museum.

The helicopters have flown more than 60,000 hours in operations in Australia and overseas.
