In the event of a nuclear war, what would be the primary mission of the Soviet navy?

The primary mission of the Soviet navy during a nuclear war would focus on conducting nuclear strikes from SSBNs, or nuclear-powered ballistic missile submarines. This is because the Soviet naval strategy was heavily centered on deterrence and the launch capabilities of these submarines were critical for delivering nuclear payloads. SSBNs were designed to be stealthy and remain submerged for extended periods, allowing them to launch nuclear missiles from undetected positions. This capability was vital for maintaining a second-strike capability, which is essential in nuclear deterrence doctrine.

While other missions such as conducting naval blockades, protecting shipping lanes, and disrupting enemy communication lines are important roles for a navy, the unique nature of nuclear warfare places the ability to launch nuclear strikes as the most pivotal mission for the Soviet navy in such a scenario. The emphasis on SSBNs reflects the strategic priority of ensuring a robust and survivable nuclear response in the event of conflict.
