Sigma KEE - AGM114
KB Term: 

AGM-114 Hellfire (Helicopter launched fire-and-forget) is a U.S. air-to-ground missile system designed to defeat tanks and other individual targets while minimizing the exposure of the launch vehicle to enemy fire. Hellfire uses laser guidance and is designed to accept other guidance packages. It is used on helicopters against heavily armored vehicles at longer standoff distances than any other U.S. Army missiles now in the inventory. The Hellfire II is the optimized version of the laser family of Hellfire missiles. The Longbow Hellfire Modular Missile System is an air-launched, radar aided, inertially guided missile that utilizes millimeter-wave radar technology. Despite the expanded acronym, most versions of the Hellfire missile are not truly fire-and-forget -- all the laser-guided versions require constant illumination or painting of the target from launch to impact. The AGM-114L is a true fire-and-forget weapon: it requires no further guidance after launch and can hit its target without the launcher being in line of sight of the target. The Hellfire (along with the Maverick and the air-launched TOW) was to be replaced by the Joint Common Missile (JCM) around 2011. The JCM was developed with a tri-mode seeker and a multi-purpose warhead that would combine the capabilities of the several Hellfire variants. In the budget for FY2006, the US Department of Defense canceled a number of projects that they felt no longer warranted continuation based on their cost effectiveness, including the JCM. Due to the U.S. military's continuing need for a proven precision-strike aviation weapon in the interim until a successor to the JCM is fielded, as well as extensive foreign sales, it is likely the Hellfire will be in service for many years.

Parents AGM An air-to-surface missile (also, air-to-ground missile, ASM or AGM) is a missile designed to be launched from military aircraft (bombers, attack aircraft, fighter aircraft or other kinds) and strike ground targets on land, at sea, or both. They are similar to guided glide bombs but to be considered a missile, they usually contain some form of propulsion system. The two most common propulsion systems for air-to-surface missiles are rocket motors and jet engines. These also tend to correspond to the range of the missiles - short and long, respectively. Some Soviet air-to-surface missiles are powered by ramjets, giving them both long range and high speed. (from Wikipedia)
  AntiArmorWeapon A weapon designed to damage the armor of military vehicles or bunkers
  BeamRidingGMissile Beam-riding guidance leads a missile to its target by means of radar or a laser beam. It is one of the simplest forms of radar or laser guidance. The main use of this kind of system is to destroy airplanes or tanks. First, an aiming station (possibly mounted in a vehicle) in the launching area directs a narrow radar or laser beam at the enemy aircraft or tank. Then, the missile is launched and at some point after launch is gathered by the radar or laser beam when it flies into it. From this stage onwards, the missile attempts to keep itself inside the beam, while the aiming station keeps the beam pointing at the target. The missile, controlled by a computer inside it, rides the beam to the target. The aiming station can also use the radar returns of the beam bouncing off the target to track it, or it can be tracked optically or by some other means. (from Wikipedia)
