The USS Skate (SSN 578) arrived at the Norfolk Naval Shipyard and became the first nuclear powered submarine to undergo a major overhaul at the Portsmouth location. With the nuclear refueling and installation of the SUBSAFE package, the Skate remained in the yard until September 1967. Skate was the first submarine to finish this major conversion program which was instituted after the loss of Thresher (SSN-593) in 1963. After sea trials and a shakedown cruise in the Caribbean, the submarine returned to New London and participated in exercises involved in the development of new undersea tactics and equipment.
