When was the SSBN fleet first deployed?

The SSBN fleet, which stands for Submarine Ballistic Missile Nuclear, was first deployed by the United States in 1960 with the launch of the USS George Washington (SSBN-598). This represents a significant moment in naval history as the SSBNs were designed to provide a continuous at-sea deterrent to nuclear threats. The deployment of these submarines was a critical advancement in military capability during the Cold War, as they allowed for a stealthy and reliable second-strike capability in the event of a nuclear attack. This attribute significantly enhanced national security by ensuring that even if land-based missile silos were destroyed, the SSBNs could still retaliate. The decision to deploy submarines for this purpose marked a major evolution in nuclear strategy, reflecting the changing dynamics of warfare and deterrence strategies of that era.
