AGM-114 Hellfire (Helicopter launched fire-and-forget) is a U.S. missile system.

[edit] Overview

Hellfire was initially designed to be primarily used as a "tank-buster", launched from helicopters to defeat armored vehicles. It has since matured to be a comprehensive weapon system which can be deployed from rotary wing aircraft, fixed wing aircraft, naval assets and land based systems against a variety of targets.

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) 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.

[edit] Combat history

Hellfire missiles were successfully used by U.S. Army troops against seven targets during Operation Just Cause in Panama in 1990. Hellfire was used in the opening strikes of Operation Desert Storm on January 17, 1991, when eight AH-64 Apache helicopters used Hellfire missiles as well as Hydra 70 rockets to destroy two Iraqi early warning ground-control radar sites. In early 2002, RQ-1 Predator UAVs were armed with Hellfires and used in combat.

The Hellfire missile has been used extensively in the 2003 invasion of Iraq and ongoing operations in Iraq.

As of January 14, 2006 the CIA reportedly used 10 Hellfire missiles from unmanned MQ-1 Predator combat air vehicles to strike at Ayman al-Zawahiri, Al-Qaeda second in command with many aliases. It later turned out that that the target was not present at the time. See the airstrike on Damadola for more information.

Israel also uses them for assassination operations, euphemistically dubbed "targeted killings", including the founder and spiritual leader of Hamas: Sheikh Ahmed Ismail Yassin. Ahmed Yassin was killed in an Israeli attack on March 22, 2004. While he was being wheeled out of an early morning prayer session, an Israeli helicopter gunship fired Hellfire missiles at Yassin and both of his bodyguards. They were killed instantly, along with eight civilians. In order to minimise casualties, Israel purportedly removed the explosive warhead, while replacing this weight with ballast to keep the weapon stable in flight[citation needed]. Israel claims the weapon allows for accurate attacks that reduce casualties among innocent civilians, though this has been disputed.[citation needed].

The system has been tested for use on the High Mobility Multipurpose Wheeled Vehicle (HMMWV) and the Improved TOW Vehicle (ITV). Test shots have also been fired from a C-130 Hercules (see photos below). Sweden and Norway use the Hellfire for coastal defense, and Norway has conducted tests with Hellfire launchers and aiming stations mounted on the Stridsbåt 90 coastal assault boat[1].
