The length was 130 metres (430 ft), breadth 10.1 metres (33 ft), height 9 metres (30 ft) and the displacement 8,400 long tons (8,500 t) submerged and 7,600 long tons (7,700 t ...
The first sea-based missile deterrent forces were a small number of conventionally powered cruise missile submarines and surface ships fielded by the United States and the Soviet Union in the 1950s, deploying the Regulus I missile and the Soviet P-5 Pyatyorka (also known by its NATO reporting name SS-N-3 Shaddock), both land attack cruise missiles that could be launched from surfaced submarines.
She began operations as an attack submarine from Pearl Harbor. Her last Polaris missile was removed in Bangor, Washington, on 1 June 1981.

[9] Submerged launch was not an operational capability for the Soviets until 1963, when the R-21 missile (SS-N-5) was first backfitted to Project 658 (Hotel class) and Project 629 (Golf class ...
