Ballistic Missile / Guided Missile Subs
SSBN / SSGN
Strategic deterrence has been the sole mission of the fleet
ballistic missile submarine (SSBN) since its inception in 1960. The SSBN
provides the nation's most survivable and enduring nuclear strike capability.
The Ohio-class submarine replaced aging fleet ballistic missile submarines built
in the 1960s and is far more capable.
Ohio-class / Trident ballistic missile submarines provide the
sea-based "leg" of the triad of US strategic deterrent forces. The first
four Ohio-class submarines are converting to guided missile submarines (SSGN)
with an additional capability to transport and support Navy special operations
forces.
