This was the first Ballistic missile deployed by the Soviet Navy. Development started in 1954 and was based on the Army's R-11 missile. Land based tests began in the spring of 1955 and out of 14 launches 12 were successful. The first submarine to carry this missile was the converted Pr. 611 submarine B-67. The submarine was ready in September 1955 and on 16 September 1955 it made the world's first ballistic missile launch from a submarine. The missile was accepted into service in 1959.
During the service life of these missiles from 1958 to 1967 a total of 77 launches were made from a submarine. Out of those 59 were successful, 3 failed due to control problems, 7 failed due to crew errors and 8 failed for unknown reasons. A total of 10 submarines carried this missile.
This missile was surface launched and required 2 hours to prepare for launch while underwater and then 5 more minutes while on the surface. Three missiles were launched with 5 minute intervals. Missile could be fired from a submarine moving at 8 to 12 knots and at sea states 4-5.
This was a single-stage missile with a liquid fuel engine, controlled by the gas jets mounted in the exhaust of the engines. The missile was fueled by kerosene and nitric acid.
