What will replace the Ohio-class?
Columbia class
Eventually, all Ohio-class SSBNs will be replaced by the Columbia class. The four SSGNs, meanwhile, will be replaced by the Virginia-class nuclear attack submarine, which will have vertical-launch systems capable of firing 12 to 40 Tomahawks or Harpoon anti-ship missiles.
What will replace the Virginia class?
They are scheduled to replace older Los Angeles-class submarines, many of which have already been decommissioned. Virginia-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to remain into the 2070s….Virginia-class submarine.
