This was the first Soviet submarine launched ICBM. The design started in 1964 and it was accepted into production in March 1974. This missile had two stages and used an astronavigation system which determined its position according to the stars. Trials lasted from 1969 to 1974 and a total of 39 launched were made. Twenty of these were from a submerging test-stand while the other nineteen were from submarine K-145 (Hotel I (Pr.658)) which was converted under Project 701 and had six launch tubes.
