Columbia-Class SSBN Heads for Detailed Design Phase

ARLINGTON, Va. — The Columbia-class nuclear-powered ballistic-missile submarine program, formerly known as the Ohio-Class Replacement Program, received Milestone B approval on Jan. 4, the Department of the Navy announced in a Jan. 9 release.

This decision by Frank Kendall, undersecretary of Defense for Acquisition, Technology and Logistics, authorizes the Columbia class to enter into the Engineering and Manufacturing Development Phase, permitting the transition from preliminary design to detail design.

“Milestone B enables the program to move into the Engineering and Manufacturing Development phase where we will focus our attention on achieving an 83 percent design maturity prior to construction start in 2021, and ensuring we meet the requirements necessary to meet a successful Production Readiness Review, our next major program event,” said Capt. David Goggins, the Navy’s Columbia program director. “The Navy is committed to delivering Columbia on time and within budget while taking advantage of every opportunity to achieve further cost savings.”

The 12-ship Columbia class will replace the existing Ohio-class nuclear-powered ballistic submarine force, which provides the nation with a credible and survivable sea-based deterrent. The first patrol of the lead ship, SSBN 826, is scheduled for fiscal 2031.
