The AGM-114 Hellfire is an air-to-ground missile (AGM) first developed for anti-armor use,[6] later developed for precision[7] drone strikes against other target types, especially high-value targets.[8] 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.[9] It has a 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 (45kg) class air-to-ground precision weapon for the armed forces of the United States and many other nations. It has also been fielded on surface platforms in the surface-to-surface and surface-to-air roles.[10]
Most variants are laser-guided, with one variant, the AGM-114L "Longbow Hellfire", being radar-guided.[11][12] 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.[13]

The development of the Hellfire Missile System began in 1974 with the United States Army requirement for a "tank-buster", launched from helicopters to defeat armored fighting vehicles.[14][15][unreliable source?]
The Hellfire II, developed in the early 1990s is a modular missile system with several variants, and entered service with the U.S. Army in 1996.[16] 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. The General Atomics MQ-1 Predator and MQ-9 Reaper unmanned combat aerial vehicles (UCAVs) carry the HellfireII, but the most common platform is the AH-1Z Viper helicopter gunship, which can carry up to 16 of them. The AGM-114L, or Longbow Hellfire, is a fire-and-forget weapon: equipped with a millimeter-wave (MMW) active radar homing, it requires no further guidance after launch—even being able to lock on to its target after launch[17]—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 (104lb), including the 9 kilograms (20lb) warhead, and has a range of 7.1–11 kilometres (4.4–6.8mi) depending on trajectory.[18]
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[19][20] to engage targets that formerly needed multiple Hellfire variants. It will replace AGM-114K, M, N, and P variants in U.S. service.[21]
In October 2012, the U.S. ordered 24,000 HellfireII missiles, for both the U.S. armed forces and foreign customers.[22]
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 increment1 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.[23][24]
Operational history
M1A1 Abrams main battle tank destroyed by friendly fire in 1991 Gulf War; one Abrams is thought to have been accidentally set on fire by a Hellfire missile fired from an Apache helicopter.[25]
In 2009, the British Ministry of Defence (MoD) acknowledged that Army Air Corps (AAC) AgustaWestland Apaches had used AGM-114 Hellfire missiles against Taliban forces in Afghanistan. The MoD stated that 20 missiles were used in 2008 and a further 20 in 2009. In the British Parliament, Liberal Democrat politician Nick Harvey argued that the "Parliament must be reassured these are a weapon of last resort."[26]
AGM-114 Hellfire missiles were been used to kill Hamas leader Ahmed Yassin by the Israeli Air Force (IAF) in 2004,[27][28] and by the US military to kill American-born Islamic cleric Anwar al-Awlaki in Yemen in 2011,[29] Al-Qaeda operative Abu Yahya al-Libi in Pakistan in 2012, al-Shabaab militant Mukhtar Abu Zubair in Somalia in 2014,[30] and British-born ISIL executioner Mohammed Emwazi (also known as "Jihadi John") in Syria in 2015.[31]
The AGM-114 has occasionally been used as an air-to-air missile. The first operational air-to-air kill with a Hellfire took place on 24May 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.[32][33] The second operational air-to-air kill with a Hellfire occurred on 10February 2018, after an Iranian UAV entered Israeli airspace from Syria. An Israeli Air Force AH-64 launched a Hellfire missile at the UAV, successfully destroying it.[34][third-party source needed]
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;[35] it was later returned.[36] A US official said that this was an inert "dummy" version of the Lockheed system stripped of its warhead, fuse, guidance equipment and motor, known as a "Captive Air Training Missile".[37][38]

AGM-114R9X
The Hellfire R9X is a Hellfire variant with a kinetic warhead with pop-out blades instead of explosives, used against specific human targets. Its lethality is due to 45kg (100lb) of dense material with six blades flying at high speed, to crush and cut the targeted person[47]— the R9X has also been referred to as the 'Ninja Missile'[48] and 'Flying Ginsu'.[47] It is intended to reduce collateral damage when targeting specific people.[49] Deployed in secret in 2017, its existence has been public since 2019. This variant was used in the killing in 2017 of Abu Khayr al-Masri, a member of Al-Qaeda's leadership, and in 2019 of Jamal Ahmad Mohammad Al Badawi, accused mastermind of the 2000 USS Cole bombing.[50][51] The weapon has also been used in Syria,[52] and in Afghanistan against a Taliban commander.[53][54] It was used twice in 2020 against senior al-Qaeda leaders in Syria; in September 2020 US officials estimated that it had been used in combat around six times.[55][56][57][58][59]
Hellfire missiles fired by a Reaper drone[60] were used on 31 July 2022 to kill Ayman al-Zawahiri,[7] the leader of Al-Qaeda, who had formerly been involved in planning the 9/11 and other attacks on US targets. It was reported that the missile hit him on a balcony, causing minimal collateral damage. Reports stress that avoiding other casualties was a priority for the mission, following drone attacks that killed several uninvolved people, attracting much criticism. It is widely thought that the Hellfires were the R9X variant, but a United States Special Operations Command spokesman declined to comment, while confirming that the R9X was "in US Special Operations Command's munitions inventory".[61][62]

The system has been tested for use on the Humvee and the Improved TOW Vehicle (ITV). Test shots have also been fired from a C-130 Hercules. Sweden and Norway use the Hellfire for coastal defense and have conducted tests with Hellfire launchers mounted on the Combat Boat 90 coastal assault boat.[71]
The US Navy was evaluating the missile for use on the Freedom-class littoral combat ship and Independence-class littoral combat ship from 2014.[72] The missile was successfully fired from a LCS in early 2017[73] This system is set to deploy by late 2019.[74]
In 2016 the Longbow Hellfire was tested by the US Army using a 15-tube Multi-Mission Launcher mounted on a Family of Medium Tactical Vehicles (FMTV) truck. The MML is an Army-developed weapon system capable of deploying both surface-to-surface and surface-to-air missiles.[75]
