LCS, Littoral Combat Ship Vessel

Module changes were envisioned to allow a single LCS to change roles in a matter of hours at any commercial port allowing a group of LCS' to optimize their effectiveness against a developing threat very rapidly. A navy report, the OPNAV (OPerations chief, NAVy report) based on the results of a January 2012 sustainment wargame is reported to state that, possibly for logistics reasons, the mission module changes may take as long as weeks, and that in the future the navy plans to use LCS ships with a single module, with module changes being a rare occurrence.
- Surface warfare
The surface warfare mission module is intended to deal only with small boats and is called "best swarm killer in the surface fleet". It includes two 30mm gun mission modules manufactured by Teledyne Brown Engineering, Inc.
In January 2011, the U.S. Navy recommended that Raytheon's Griffin missile system be selected as the replacement for the NLOS-LS missile. This would lower the missile range of the LCS from 25 miles to 3.5 miles. The packages are to be deployed in sets of three, with 15 per set for a total of 45 missiles. Initial deployment is for 2015, with a longer ranged version to enter service around 2017. The longer range missile will be chosen in a competition for a "beyond the horizon" system.
