SSGNs.
The TRIDENT SWS and support facilities were designed from the beginning to handle the newer and larger missile system with minimal impact and cost. By early 2003, two of the four SSBNs had completed backfit; one was fully operational and making deployments in the Pacific, and the other was finishing its final certification and testing. The second submarine will also be homeported in the Pacific. The last two SSBNs were scheduled to start their backfit in FY 2005 and FY 2006.
In the pacific and ready for action.
