U.S. Navy USS Mustin Destroyer Fires Mk 45 Gun Proving Indo-Pacific Combat Readiness

USS Mustin (DDG-89) conducted live-fire exercises with its Mk 45 5-inch naval gun in the Indo-Pacific, demonstrating surface warfare readiness. The exercise validated crew proficiency and weapon system operability following a recent maintenance period. The Mk 45 Mod 4 gun is the primary surface fire support and close-in surface engagement weapon on Arleigh Burke-class destroyers. The exercise is part of routine combat readiness certification for forward-deployed naval forces in the Seventh Fleet area of operations.
