USS Arkansas (CGN-41) was a Virginia-class nuclear-propelled guided-missile cruiser of the U.S. Navy. She was in commission (in active service) from October 1980 through July 1998. Her primary missions were in defending aircraft carrier task forces in air defense (AAW) and antisubmarine warfare (ASW) by using her guided missiles, radar systems, and sonar systems.
For her short-range self-defense, especially for defense against enemy anti-ship missiles, Arkansas carried two automated Phalanx radar-directed 20 millimeters (0.79Β in) rapid-fire guns. Also, her two 5-inch rapid-fire naval guns had some capability for anti-aircraft defense.
