Beginning in 2002 through 2010, 22 of the 24 88-inch (2.2 m) diameter Trident missile tubes will be modified to contain large vertical launch systems (VLS),
one configuration of which may be a cluster of seven Tomahawk cruise missiles. In this configuration, the number of cruise missiles carried could be a maximum of 154, the equivalent of what is typically deployed in a surface battle group. Other payload possibilities include new generations of supersonic and hypersonic cruise missiles, and Submarine Launched Intermediate Range Ballistic Missiles (SLIRBM)[3], unmanned air vehicles (UAVs), the ADM-160 MALD, sensors for anti-submarine warfare or intelligence, surveillance and reconnaissance missions, counter-mine warfare payloads such as the AN/BLQ-11 Long Term Mine Reconnaissance System (LMRS), and the broaching universal buoyant launcher (BUBL) and stealthy affordable capsule system (SACS) specialized payload canisters.
