Description: The MK 46 is a Naval derivative of the 30mm gun turret originally designed for the USMC Expeditionary Fighting Vehicle. The MK 46 GWS is a remotely operated naval gun system that uses a 30mm high velocity cannon, a forward looking infrared sensor, a low light television camera, and a laser rangefinder for shipboard self defense against small, high speed surface targets. The gun can be operated locally at the gun turret or remotely at the Remote Operating Console in the Combat Information Center (LPD 17 class)/Mission Control Center (LCS class).
Background: The requirements documents for the LPD 17 and LCS ship programs included the need for weapons systems capable of defeating small, fast, highly maneuverable surface craft. The MK 46 GWS was selected to provide these ships a capability against small surface craft. The MK 46 GWS is permanently installed aboard LPD 17 class ships. It is part of the Surface Warfare (SuW) mission module for LCS class ships.
The MK 46 Mod 2 GWS incorporates new open architecture, fault isolation software and an embedded trainer. The Navy is installing the MK 46 Mod 2 GWS aboard LPD 17 class ships during construction. The Navy designed and developed the SuW mission module for LCS class ships. Two SuW mission modules (each including one MK 46 Mod 2 GWS) will be installed on each LCS class ship
