TheÂ U.S. Navy has tested various defense platforms ofÂ Nimitz-class aircraft carrier USS Abraham LincolnÂ over a 13-day period.
The service branchÂ said ThursdayÂ it conducted theÂ Combat Systems Ship Qualification Trials from April 20 to May 2 to determine if Lincoln could operate the Enhanced NATO Sea Sparrow Missile System, rolling airframe missile launchers andÂ close-inÂ weapons systems.
CIWS is aÂ 20-millimeter gatling gun that uses aÂ forward-looking infrared camera designed to detect and attack targets.
The system fired at aÂ towed drone unit during aÂ simulated air defense drill and at aÂ high-speed maneuvering seaborne target during a surface engagement drill.
RAM launchers, which are equipped withÂ built-in sensors,Â fired a RIM-162D Sea Sparrow missile and a RIM-116 test unit during tests.
ENSSMS is aÂ semi-active missile that requires directors to input a feed prior to locating a target.
The carrier re-entered service after it completed a half-life refueling and overhaul maintenance period last year.
