 Welcome to All Hands Update, I'm Petty Officer Ian Cotter. This year marks 59 years of the Fleet Ballistic Missile Program. The Navy has developed six generations of submarine-launched ballistic missiles and four classes of nuclear-powered ballistic missile submarines. Today, the Navy's workhorse of the Ballistic Missile Submarine Fleet is the Ohio-class submarine. It has played a major role in ensuring the U.S. is standing in the world by maintaining a capable and effective nuclear deterrent. Beginning in 2027, the Navy will replace the current fleet of 14 Ohio-class submarines with 12 Ohio replacement submarines. The Ohio replacement and its strategic weapons system will be a national asset whose endurance and stealth will enable the Navy to provide credible strategic deterrence for the next 70 years.
