The U.S. Navy has awarded BAE Systems a $46.8 million contract option to deliver four additional Mk 45 Naval Guns.
The contract modification calls for upgrading existing guns to the Mod 4 configuration to increase the firepower and extend the range of the weapons. This modification to the initial 10-gun contract brings the full value of the award to $176.8 million for the 14 guns.
The Mk 45 Mod 4 provides NSFS range of more than 20 nautical miles (36 km) with the Navy’s new 5-inch Cargo projectile and an improved propelling charge.
Work on the Mk 45 Mod 4 conversions will be performed at the BAE Systems’ facility in Louisville, Kentucky, with support from the company’s supplier base, and is expected to be complete by 2021.
