As articulated in their respective long-term shipbuilding plans, the Navy and the Coast Guard intend to spend more than $47 billion combined over the next 20 years to purchase a total of 83 small combatants. Of that number, the Navy plans to purchase 53 littoral combat ships (LCSs), in addition to the two that were purchased in 2005 and 2006. The LCSs will be built using two different hull designs one, a semiplaning monohull; the other, an aluminum trimaran although the exact mix of hulls has not yet been determined. The ships will carry one of three sets of equipment, or mission packages, depending on which mission they are expected to perform (antiship, antisubmarine, or countermine warfare). The Coast Guard plans to buy five new high-endurance cutters, commonly referred to as national security cutters (NSCs), and 25 new medium-endurance cutters, often called offshore patrol cutters (OPCs). Three other NSCs ordered prior to 2009 have been built or are currently under construction. Although the Coast Guard plans to begin buying the offshore patrol cutter in 2015, it is not yet certain what the OPC will look like or if it will be confined to one class of ship. Together, the NSCs and OPCs, which are designed to operate 50 nautical miles beyond the U.S. coastline, are part of the resources and force structure that make up the Coast Guards Deep-water assets. As the designation small combatant implies, the Navys LCSs and the Coast Guards NSCs and OPCs are designed to be significantly shorter in length, lighter in weight, and shallower in draft than most Navy surface warships (carriers, amphibious ships, cruisers, and destroyers). For instance, the Navys LCSs have a full-load displacement the weight of the ship plus its crew, weapons, fuel, and cargo of about 3,300 tons. The national security cutter displaces about 4,300 tons of seawater, and the most recent notional design of the offshore patrol cutter would have the ship displace 3,700 tons. By contrast, the most modern Arleigh Burke class destroyers, the backbone of the Navys surface combatant force, displace about 9,500 tons; amphibious ships displace from 16,000 to 45,000 tons; and aircraft carriers displace about 100,000 tons.
