The Javelin System is a man-portable, fire-and-forget, medium-range antitank weapon system consisting of the Command Launch Unit (CLU) and the Round.  The CLU's Imaging infrared system is used to detect targets during conditions of poor visibility and night operations.  The round consists of the fire-and-forget missile and the discardable Launch Tube Assembly (LTA).  The fire-and-forget capability increases the gunners ability to survive and continue fighting.  The Javelin can kill a target in excess of 2000 meters.  In addition, the missile has two gunner-selectable flight modes.  The top attack mode allows the missile to impact on top of the target and the direct attack mode allows the missile to fly more directly at the target.  The Javelin has a "soft launch" for minimized launch signature and fireing from enclosure capability.  An elevated trajectory, combined with tandem, shaped-charge warheads, optimizes the Javelin's lethality against modern tanks.
