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 was originally developed under the name Heliborne, Laser, Fire and Forget Missile, which led to the colloquial name "Hellfire" ultimately becoming the missile's formal name.[3] 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.

Description

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, AGM-114L "Longbow Hellfire", being radar guided.[4][5] 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.[6]

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.[7][8] Production of the AGM-114A started in 1982.

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, Reaper and AH 665 Tiger, 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[9]—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 47 kilograms (104 lb), including the 9 kilograms (20 lb) warhead, and has a range of 8,000 metres (26,000 ft).

The AGM-114R "Romeo" Hellfire II entered service in late 2012. It uses a semi-active laser homing guidance system and a K-charge multipurpose warhead[10][11] to engage targets that previously needed multiple Hellfire variants. It will replace AGM-114K, M, N, and P variants in U.S. service.[12]

In October 2012, the U.S. ordered 24,000 Hellfire II missiles, for both the U.S. armed forces and foreign customers.[13]

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. Due to budget reductions, JAGM development was separated into increments, with Increment 1 focusing on adding a millimeter wave radar to the Hellfire-R to give it a dual-mode seeker, enabling it to track moving targets in bad weather.[14][15]

Operational history

M1A1 Abrams main battle tank destroyed by friendly fire in 1991 Gulf War, hit in rear by Hellfire missile, and penetrated by sabot tank round.

Since being fielded, Hellfire missiles have been used in combat in Operation Just Cause in Panama, Operation Desert Storm in the Persian Gulf War, Operation Allied Force in Yugoslavia, Operation Enduring Freedom in Afghanistan, in Operation Iraqi Freedom, where they have been fired from Apache and Super Cobra attack helicopters, Kiowa scout helicopters, and Predator and Reaper unmanned combat air vehicle (UCAV) drones.

In 2008, the usage of the AGM-114N metal augmented charge (MAC) variant caused controversy in the United Kingdom when it was reported that these thermobaric munitions were added to the British Army arsenal. Thermobaric weapons have been condemned by human rights groups.[16] The UK Ministry of Defence refers to the AGM-114N as an "enhanced blast weapon".[16]

The AGM-114 has been the munition of choice for airborne targeted killings that have included high-profile figures such as Ahmed Yassin (Hamas leader) in 2004 by the Israeli Air Force,[17][18] Anwar al-Awlaki (American-born Islamic cleric and Al Qaeda in the Arabian Peninsula leader) in Yemen in 2011,[19] Abu Yahya al-Libi in Pakistan in 2012 by the United States, and Moktar Ali Zubeyr (also known as Ahmad Abdi Godane, leader of al-Shabaab) in Somalia in September 2014.[20] US officials are almost certain that on 12 November 2015, Jihadi John, real name Mohammed Emwazi, was killed by a drone-fired Hellfire missile, while travelling in a car near Clocktower Square, in Raqqa, Syria, the place where ISIL carried out public executions.[21]

The AGM-114 occasionally saw use as an air-to-air missile. The first operational air-to-air kill with a Hellfire took place on 24 May 2001, after a civilian Cessna 152 aircraft entered Israeli airspace from Lebanon, with unknown intentions and refusing to answer or comply with ATC repeated warnings to turn back. An Israeli Air Force AH-64A Apache helicopter fired on the Cessna, resulting in its complete disintegration.[22] The second operational air-to-air kill with a Hellfire occurred on 10 February 2018, after an Iranian UAV entered Israeli airspace from Syria. An Israeli Air Force AH-64 launched a missile on the UAV, successfully destroying it.[23]

In January 2016 the Wall Street Journal reported that one training missile without a warhead was accidentally shipped to Cuba in 2014 after a training mission in Europe.[24] The dummy missile was later returned.[25] A US official said that this was an inert "dummy" version of the Lockheed system, known as a "Captive Air Training Missile". It is stripped of its warhead, fuse, guidance equipment and motor.[26][27]
