Which class of submarines is to be converted to SSGNs?

The Ohio-class submarines are designated for conversion to SSGNs, or guided missile submarines. This class originally included ballistic missile submarines, but their conversion allows them to carry and launch cruise missiles, specifically Tomahawk missiles, as well as to serve special operations missions. These modifications enhance their versatility in modern naval operations, enabling them to carry out various missions beyond nuclear deterrence, which was the primary role of the original Ohio-class submarines.

The conversion process involves significant alterations to the submarine's internal structure and systems, allowing them to fulfill dual roles: as platforms for land attack and as silent special operations support vessels. This reconfiguration reflects the Navy's strategic shift towards more flexible, multi-mission platforms that can adapt to changing combat scenarios.

While other classes such as the Virginia-class, Seawolf-class, and Los Angeles-class submarines are capable in their own right, it is the Ohio-class that was specifically chosen for this transformation due to its existing capabilities and the potential for modernization to meet contemporary naval warfare demands.
