BAE Systems Inc. said Wednesday it will work to incorporate into the Mk 45 naval guns several Mod 4 configuration functions, such as new mount subsystems, a 62-caliber barrel, new control tools and a gun shield.
The subsidiary will initially update six Mk 45 platforms and eventually overhaul four additional gun systems if the service branch exercises its option in 2016.
Deliveries will start in October 2017 and continue through January 2020.
