Under the requirements of the Strategic Arms Reduction Treaty, START II, which was agreed in June 1992, the number of strategic missile submarines was limited to 14 from the year 2002. Rather than decommissioning these four submarines, the US Navy is converting them to SSGNs (conventionally armed nuclear-powered) submarines. In September 2002, Electric Boat received a contract for the conversion of USS Ohio, Michigan, Florida and Georgia. The submarines are being refitted with up to 154 Tomahawk TLAM (land attack) missiles and will also be capable of conducting special operations missions with accommodation for Northrop Grumman Advanced SEAL delivery systems (ASDS), mission control centre and 102 special operations troops.
General Dynamics Advanced Information Systems is modifying the Trident fire control system for the Tomahawk weapon control. Northrop Grumman Electronic Systems is adapting the missile launch tubes, developing a Multiple All Up Round Canister (MAC) which will provide storage and launch of up to seven Tomahawk missiles from each of the submarine's 22 missile tubes."
