LCS Mk-50 Gun Mission Module (GMM) Integrated Power System

The Surface Warfare (SUW) Mk-50 Gun Mission Module (GMM) that houses the Mk-46 Gun Weapon System (GWS) is one of several key Mission Modules developed by PMS-420 that contribute to the tactical warfighting capability of the Littoral Combatant Ship (LCS). RCT Systems proposes to develop a power conversion system to replace the battery charger that directly converts ships 440VAC to 28VDC so that the GMM weapon system can be fired from Sea Frame power. The ultimate goal is to have a power conversion system that would provide Sea Frame power to be able to fire the GMM, and also charge an Energy Storage Unit (ESU), so that the weapon can be fired under all conditions, including if the LCS were to lose power due to battle damage or other power system casualty.
