Northrop to Develop New Guided Ammo for Mk110 Naval Gun Mount

The U.S. Navy awarded Northrop Grumman a contract to develop 57mm guided ammunition for the Mk110 Naval Gun Mount.

Under the terms of the contract, the company will test and mature the munition for qualification.

The 57mm guided high-explosive ammunition has the ability to continuously maneuver in-flight as it moves toward a designated target. Designed to defend against fast-moving surface threats, drones, and swarming threats, the guided 57mm ammunition features an onboard seeker to acquire moving targets and a fuze with the ability to self-select for either proximity or point-detonation mode to engage and defeat the intended target.

The 57mm round leverages the company's Precision Guidance Kit. Utilizing seekers and an aft-maneuver system, the round provides continuous trajectory guidance. It will give the Navy greater standoff range and a cost-effective solution against small, fast-moving threats, without any weapon system modifications.
