The US Navy's second Independence-class littoral combat ship (LCS) USS Coronado has successfully performed live-fire testing off the coast of California.
During the test, the crew and embarked surface warfare (SUW) mission package (MP) detachment tracked and neutralised both single and multiple fast inshore attack craft.
The test was conducted using the ship's core weapons system, the Mk 110 57mm gun and the embarked SUW MP Mk 46 30mm gun weapon systems (GWS).
USS Coronado commanding officer commander Peter Kim said: "After extensive testing, the Mk 110 serves as a powerful deterrent capability in protection of both the USS Coronado's crew and those of her sister littoral combat ships.
"The Mk 110 paired with the surface warfare mission package expands the ship's ability to defend against threats faced in a global environment and testing further proves these weapons systems are highly-capable and versatile against multiple representative fast (inshore) attack craft."
The live-fire testing was designed to assess the accuracy and capability of USS Coronado's weapons systems against attack craft.
The test is part of the initial operational test and evaluation (IOT&E) of the Independence-variant LCS operating with a surface warfare mission package.
BAE Systems' multi-mission 57mm Mk 110 Mod 0 naval gun system is a medium-calibre shipboard weapon designed to deliver high rates of accurate fire against threats, including surface, airborne and sea-based.
It is capable of firing up to four rounds per second using programmable, proximity-fused smart ammunition, which features six selectable modes of fire.
