Guided-Missile Submarines (SSGN)
SSGN CONVERSIONS
SSGN-726 TO SSGN-729
The four oldest Ohio-class boomers, reborn. After the 1994 Nuclear Posture Review determined 14 SSBNs were sufficient for strategic deterrence, these four boats had their 24 Trident missile tubes replaced with 22 tubes carrying 7 Tomahawk cruise missiles each - 154 per boat. Together, the four SSGNs carry more than half the submarine force's entire vertical launch capacity. They also carry 66 special operations forces with dry deck shelters for SEAL delivery. All four expected to retire by 2028, replaced by Virginia-class Block V boats with the Virginia Payload Module.

Ohio-class
Trident II D-5 Boats
TRIDENT II
SSBN-734 TO SSBN-743
The backbone of America's sea-based nuclear deterrent. Ten boats commissioned with the Trident II D-5 - the most accurate and lethal submarine-launched ballistic missile ever deployed. Each boat carries 20 D-5 missiles (reduced from 24 under New START treaty). At any given time, four to five of these boats are on 'hard alert' in designated patrol areas, ensuring that no adversary can launch a first strike without facing catastrophic retaliation. The Columbia-class will begin replacing these boats starting in 2031.
