苏联海军于20世纪50年代建造G级常规动力弹道导弹潜艇和H级弹道导弹核潜艇之后,按照最初的发展思路,计划沿着两条途径继续发展和壮大海军战略核力量:第一条途径是首先大量建造H级弹道导弹核潜艇,使苏联海军尽快拥有基本的海上战略核威慑力量;于此同时,把积极开发、研制新型弹道导弹核潜艇——Y级(667A型)作为第二发展途径。但是,1959年苏联战略指导思想发生了重 After the Soviet Navy built the G-class conventional ballistic missile submarine and the H-class ballistic missile submarine in the 1950s, it planned to continue to develop and expand its naval strategic nuclear forces in two ways according to the initial development plan: The first route is first A large number of H-class ballistic missile submarines were built to enable the Soviet Navy as soon as possible to have a basic maritime strategic nuclear deterrent. At the same time, Y-class 667A, a new type of ballistic missile submarine, was actively developed and developed as the second development route. However, the Soviet strategic guiding ideology took a heavy toll in 1959
