The US Navy (USN) will soon be purchasing equipment for its Columbia-class submarines, which will replace the service's Ohio-class strategic nuclear missile fleet, said Admiral James Caldwell Jr, director of the Naval Nuclear Propulsion Program.

"We'll start buying reactor plant components this year," Adm Caldwell said on 2 October during the Nuclear Energy, Naval Propulsion, and National Security Symposium, which was hosted by the Center for Strategic and International Studies think tank based in Washington, DC.
