Zc774. The USS Grayback was decommissioned for the second time on 15 January 1984 at Subic Bay Naval Station in the Republic of the Philippines. After decommissioning, Grayback was sunk as a target on 13 April 1986 in the South China Sea. This picture came from a Navy source.
But that is not the end of the special boats, just the Diesel Boats are gone; there are now a few nuclear boats converted for these missions.
