The Navy has developed a Tactical Submarine Evolution Plan that looks at rapidly inserting capability upgrades into the Virginia-class attack submarine mid-contract and considers long-term undersea warfare priorities such as converting the Columbia-class ballistic missile submarine (SSBN) production line into a guided-missile submarine (SSGN) line in the late 2030s.

This post has been updated to include additional information about potential advanced propulsion system development.

The Navy won’t begin buying its next-generation attack submarine until 2034, but researchers are already hard at work on two key components of the SSN(X) program: an advanced propulsion system for quieter operations, and the ability to control multiple unmanned underwater vehicles at once for extended influence.
