The CIWS is the affectionate nickname given to a 20mm Vulcan Cannon on board the USS George H.W. Bush aircraft carrier. It fires 4,500 rounds a minute, can hit a target five miles away and has bullets that are twice the normal size.
Aircraft carrier USS George H.W. Bush cruises deep in the Arabian Gulf for a six-month deployment in April 2017 to help ground troops defeat ISIS.
