BAE Systems to provide U.S. Navy with modernized Mk 45 guns

The Mk 45 is the lightest, most compact, 5-inch fully automatic naval gun in the world and is the most widely deployed to the U.S. Navy and other allied navies. Updates to the Mod 4 configuration include a structurally strengthened gun mount and more advanced electronics. With its stronger mount, the gun can achieve 50 percent higher firing energy, allowing munitions or projectiles to travel faster and farther. Its new fully digitized control system also provides significantly greater computing power and features a touch-screen user interface.

“The Mk 45 is the industry standard for large caliber naval guns, and the Mod 4 updates make the system easier to integrate onto the ship and more adaptable to advanced munitions,” said Joseph Senftle, vice president and general manager of Weapon Systems at BAE Systems. “As the world leader in developing and manufacturing maritime guns, we are committed to producing reliable and affordable technology that meets the warfighter’s needs today and well into the future.”

The upgraded Mk 45 guns are expected to remain in service for decades to come. The cost-effective Mod 4 conversion helps increase their adaptability for advanced munitions that are under development and are considered an essential component of future surface warfare.
