The capabilities of the surface warfare mission package on Littoral Combat Ships have been validated in live-fire testing by the USS Coronado.

In testing last month off the California coast, the USS Coronado (LCS 4) tracked and destroyed single and multiple inshore attack craft with its core weapons system -- the Mk 110 57mm gun -- and its embarked SUW MP Mk 46 30mm gun weapon systems, The U.S. Navy 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," said the ship's commanding officer, Cmdr. Peter Kim.

"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 attack craft."

The Mk 110 fires as many as four rounds per second and can use programmable, proximity-fuzed smart ammunition in six different modes.
