The Phalanx close-in weapons system (CIWS) is the U.S. Navy warship’s last line of defense against incoming anti-ship missiles. Phalanx is fully automated and mainly consists of a radar and a 20 mm M61 Vulcan Gatling gun with a firing rate of 4,500 rounds per minute. Yes, that’s forty-five 20 mm rounds each second!
