LCS, Littoral Combat Ship Vessel

- Mission module changes
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.
