Known internationally as the 57 Mk 3, the Mk 110 is a versatile, multi-mission gun with an effective range in excess of 9 nautical miles.

Paired with BAE Systems’ formidable six-mode programmable, pre-fragmented, and proximity-fused (3P) ammunition, the combination can effectively neutralize air, surface, or shore-based threats, including swarm boats and unmanned aerial systems.

By virtue of its multi-mode design, the 3P round eliminates the need for multiple round types when engaging varied targets.

USCGC Argus (WMSM-915) is the lead ship of the Heritage-class cutters of the United States Coast Guard (USCG), and a part of the OPC (Offshore Patrol Cutter) Ship Type.

The Heritage-class cutter, also known as the Offshore Patrol Cutter and the Maritime Security Cutter, Medium, is a cutter class of the United States Coast Guard (USCG), developed as part of the Integrated Deepwater System Program and built by Eastern Shipbuilding.
