Nuclear ballistic missile submarines were some of the most important deterrents in the Cold War. Created to attack land-based targets with nuclear weapons, the subs’ long-range missiles kept them beyond the reach of normal antisubmarine defenses. Their mobility made them difficult to catch and allowed them to threaten a broad sweep of locations.

The George Washington class was followed, beginning in 1963, by the similar but larger Lafayette and Benjamin Franklin classes.
