Ohio Class Nuclear Missile Submarine

The Ohio Class Ballistic Missile Submarines, often referred to as "boomers", serve as an undetectable launch platform for intercontinental missiles. They are designed specifically for stealth and the precise delivery of nuclear warheads. For decades, strategic deterrence was their sole mission. Recently, four of these submarines were converted into guided missile submarines, which provide the Navy with unprecedented strike and special operation mission capabilities from a stealthy, clandestine platform.

Ohio Class Guided Missile Submarine

The Ohio class cruise missile submarine (SSGN) program entailed the refueling and conversion of the four SSBNs to dedicated cruise missile launch submarines to support the Land-Attack/Strike mission. The SSGN also supports Special Operations Forces missions. Two of the large vertical launch tubes were converted to SOF lockout chambers and the submarine will feature dedicated accommodations for SOF personnel and their equipment.
