The AGM-114 Hellfire is an air-to-surface missile (ASM) first developed for anti-armor use, but later models were developed for precision strikes against other target types, and have been used in a number of targeted killings of high-profile individuals.
It has multi-mission, multi-target precision-strike ability, and can be launched from multiple air, sea, and ground platforms, including the Predator drone. The Hellfire missile is the primary 100-pound (45 kg) class air-to-ground precision weapon for the armed forces of the United States and many other nations.
The Hellfire can be fired from rotary- and fixed-wing aircraft, waterborne vessels and land-based systems against a variety of targets.
Most variants are laser guided, with one variant, the AGM-114L "Longbow Hellfire", being radar guided. Laser guidance can be provided either from the launcher, such as the nose-mounted opto-electronics of the AH-64 Apache attack helicopter, other airborne target designators or from ground-based observers, the latter two options allowing the launcher to break line of sight with the target and seek cover.
The Hellfire II, developed in the early 1990s is a modular missile system with several variants. Hellfire II's semi-active laser variants—AGM-114K high-explosive anti-tank (HEAT), AGM-114KII with external blast fragmentation sleeve, AGM-114M (blast fragmentation), and AGM-114N metal augmented charge (MAC)—achieve pinpoint accuracy by homing in on a reflected laser beam aimed at the target. Predator and Reaper UCAVs carry the Hellfire II, but the most common platform is the AH-64 Apache helicopter gunship, which can carry up to 16 of the missiles.
The AGM-114L, or Longbow Hellfire, is a fire-and-forget weapon: equipped with a millimeter wave (MMW) radar seeker, it requires no further guidance after launch—even being able to lock on to its target after launch and can hit its target without the launcher or other friendly unit being in line of sight of the target. It also works in adverse weather and battlefield obscurants, such as smoke and fog which can mask the position of a target or prevent a designating laser from forming a detectable reflection. Each Hellfire weighs 104 pounds (47 kg), including the 20 pounds (9 kg) warhead, and has a range of 4.4–6.8 miles (7.1–11 km) depending on trajectory. More details
