Pacific Ocean (Aug. 15, 2004) - Fire Controlman 2nd Class Albert Callos from Virginia Beach, Va., changes out 20mm "dummy" rounds with live 20mm rounds during a Phalanx Close-in Weapon System (CIWS) test fire. The CIWS combines a 20mm Gatling gun with search-and-tracking radar to provide surface ships a defense against anti-ship missiles. Kitty Hawk is currently underway in the 7th Fleet area of responsibility (AOR), demonstrating power projection and sea control as the world's only permanently forward-deployed aircraft carrier, operating from Yokosuka, Japan.
