Todays transformation efforts include advanced sensors and surveillance systems, rapid precision strike, assured access to hostile or denied areas, and a high tooth-to-tail ratio (the ratio of combat power to required support).
Forward Presence - Utilizing the two-crew concept, the four SSGNs will provide a continuous 2.4 submarines in-theater presence.
Strike Capability - Each of the converted submarines will have the capability to launch up to 154 Tomahawk land attack missiles. The SSGNs have 22 missile tubes, which can house seven missiles per tube in Multiple All-Up-Round Canisters (MACs).
Special Operations Capability SSGNs will have separate, interchangeable canisters for Special Operations Forces (SOF) equipment that can be installed in place of the MACs. Clandestine insertion and retrieval of SOF operators (via lockout chambers) will be enhanced by the ability of the SSGN to host dual dry deck shelters with SEAL Delivery Vehicles (SDVs) and/or Advanced SEAL Delivery System (ASDS).
Connectivity - SSGNs will be configured for high data rate connectivity using sail-mounted Universal Modular Masts and the Common Submarine Radio Room (CSRR). The Battle Management Center will also provide the SSGN with the capability to host an embarked joint command element.
