ARLINGTON, VIRGINIA (BNS): The US Navy has recently awarded $63 million contract to BAE Systems for upgrading seven Mk 45 Gun Systems to the Mod 4 configuration.

"The Mod 4 includes new digital features that provide for enhanced accuracy and reliability," Mark Signorelli, vice president and general manager of Weapon Systems for BAE Systems, was quoted as saying in the company news release.

The Mod 4 is an upgrade to the Mod 2 design, which significantly enhances overall mission performance.

Once produced, the gun systems will join 42 previously delivered Mk 45 Mod 4 systems currently in service with the US Navy.

Five gun systems will be installed on the CG-47 Ticonderoga-Class Cruisers as part of the Cruiser Modernization Program.

Two gun systems will be installed on newly constructed DDG-51 Arleigh Burke-Class Destroyers.

This 5-inch 62-caliber Mk 45 Mod 4 includes strengthened gun and mount subsystems, advanced control system enhancement, a modern touch-screen user interface and a low maintenance gun shield.

The DDG configuration also includes a reduced signature that makes it more difficult to detect via radar.
