AGM-114 Hellfire - Description

Description

The Hellfire today is a comprehensive weapon system, one that can be deployed from rotary- and fixed-wing aircraft, waterborne vessels and land-based systems against a variety of targets.

The development of the Hellfire Missile System began in 1974 with the U.S. Army requirement for a "tank-buster", launched from helicopters to defeat armored fighting vehicles. Production of the AGM-114A started in 1982. The Development Test and Evaluation (DT&E) launch phase of the AGM-114B took place in 1984. The DT&E on the AGM-114K was completed in Fiscal Year (FY)93 and FY94. AGM-114M did not require a DT&E because it is the same as the AGM-114K except for the warhead. Most variants are laser guided with one, 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 for maximum battlefield flexibility. 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 at once. 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 provides capability in adverse weather and battlefield obscurants (obscurants such as smoke and fog being able to mask the position of the target or to prevent the designating laser from producing a detectable reflection). Each Hellfire weighs 47 kg / 106 pounds, including the 9 kg / 20 pound warhead, and has a range of 8,000 meters. The AGM-114R "Romeo" Hellfire II entered service in late 2012. It uses a semi-active laser homing guidance system and an integrated blast fragmentation sleeve warhead to engage targets that previously needed multiple Hellfire variants. It will replace AGM-114K, M, N, and P variants in U.S. service. In October of 2012, the U.S. ordered 24,000 Hellfire II missiles, for both the U.S. armed forces and foreign customers.

The Joint Common Missile (JCM) was to replace Hellfire II (along with the AGM-65 Maverick) by 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 U.S. Department of Defense canceled a number of projects that they felt no longer warranted continuation based on their cost effectiveness, including the JCM. A possible new JCM successor called the Joint Air to Ground Missile (JAGM) is under consideration.
