Surface Vessel Weapon System
Mk-38 Machine Gun System (MGS)
mk-38 machine gun system mgs model 1 2 manually remote controlled

The Mk-38 was first employed aboard combatant and auxiliary ships conducting Mid-East Force escort operations and during Operations Desert Shield and Desert Storm. Mk-38 Mod.1s are maintained in a rotatable pool for temporary installation aboard deployed ships. Following the October 2000 attack on USS COLE (DDG 67), Task Force Hip Pocket identified an improved Mk-38 MGS as a means to increase shipboard self defense against small boat threats. In 2003, the Chief of Naval Operations documented the requirement and directed the development and fielding of the Mk-38 Mod 2. Installed aboard CG , DDG, FFG , LSD , LPD, LHD, LHA, LCC the Mk-38 Mod.2 MGS is a low cost, stabilized self defense weapon system that dramatically improves shipboard self defense.
