The 57-mm Mk 110 Naval Gun system from BAE Systems is a multi-mission capable medium-caliber shipboard weapon that has been selected for the U.S. Coast Guard’s National Security Cutter and the Offshore Patrol Cutter and is also baselined by the U.S. Navy for its Littoral Combat Ship Flight 0 and the Close-in Gun System for the DDG 1000 destroyer.
The Mk 110 Naval Gun system delivers high rates of fire with extreme accuracy against surface, airborne and shore-based threats with proven effective 6-mode programmable 57-mm Mk 295 ammunition. Sailors are able to respond quickly and effectively to eliminate all types of threats.
The 57-mm Mk 110 naval gun system is more lethal and has a higher rate-of-fire than any competing system. Linked with a digital fire control system, the 57-mm Mk 110 fires automatic salvos at up to 220 rounds per minute. Servo-controlled electro hydraulic gun laying subsystems provide robust endurance and extreme pointing accuracy, even in high sea-state conditions.
The highly compact and lightweight Mk 110 requires minimal deck penetration and space below deck for ease in integration to a variety of hull types of 150 tons or more. The system requires minimal manpower for operation and maintenance, and affords unparalleled availability through high level redundancy, built-in test functions, ready component access and onboard tools and spares.
The Mk 110 is based on Bofors Defence 57-mm Mk 3 naval gun, and once in full-rate production, will be produced at BAE Systems’ facility in Louisville, Kentucky. The naval gun system builds on successful 57-mm naval gun service in the fleets of 14 naval forces worldwide. For new ship applications calling for reduced-signature characteristics, the 57-mm Mk 110 weather shield design can be tailored to meet specific platform signature requirements.
