Atlantic Ocean (Aug. 02, 2005) Smoke rolls down the barrels of the forward-starboard-mounted Phalanx Close-In weapons System (CIWS) as it tracks and fires at an aerial target drone as it is towed over the bow of the Nimitz-class aircraft carrier USS Harry S. Truman (CVN 75). CIWS is the self-defense system that combines a 20mm gatling gun with search and tracking radar to provide surface ships with terminal defense against anti-ship missiles. Truman is currently conducting carrier qualifications and operations in the Atlantic Ocean. U.S. Navy photo by Photographer's Mate 2nd Class Floyd T. Grimm File# 050802-N-9907G-022
Aircraft carriers are warships that act as airbases for carrier-based aircraft. In the United States Navy, these consist of ships commissioned with hull classification symbols CV (aircraft carrier), CVA (attack aircraft carrier), CVB (large aircraft carrier), CVL (light aircraft carrier), CVN (aircraft carrier (nuclear propulsion) and CVAN (attack aircraft carrier (nuclear propulsion). The first aircraft carrier commissioned into the United States Navy was USS Langley (CV-1) on 20 March 1922.
