A Long Successful Service
The blighted submarine lived on for a long time after that, despite the fact that she appeared to be surplus to needs at the time of her destruction. Authorities decommissioned Grayback in May of 1964, as a result of the introduction of a new batch of Polaris projectiles and submarines into service by that year. The submarine, which had been assigned to the function of the amphibious submarine, was reactivated in August 1968 and given the new name of the LPSS-574 when she returned to service. Her modified missile storehouse was now capable of transporting a total of 67 passengers on board.
