 progressed, however, it became clear that the Soviets could not win a toe-to-toe fight in the deep water, and the information sold to the Soviets by the Walker spy ring in 1980s made it clear that the ballistic missile submarines, in particular, were very unlikely to be able to carry out their nuclear attack missions.

Realizing their vulnerability, the Soviets adopted a two-level approach. They armed their older, noisier, and less reliable "second generation" ballistic missile submarines with shorter-range nuclear weapons and deployed them as close as possible to the United States
