Pentagon revs up Hellfire missiles to attack ISIS
Ongoing U.S. and allied drone, helicopter and aircraft attacks against ISIS have led the Army to massively rev up its production of air-launched HELLFIRE missiles, a weapon regularly used to destroy Islamic State buildings, bunkers, armored vehicles, fighter positions and equipment.
The war against ISIS has depleted existing inventory of the weapon and generated a fast-growing national and international demand for HELLFIRE missiles, Army officials told Scout Warrior.
"Production of HELLFIRE has increased for quantities ordered in Fiscal Year 14 and Fiscal Year 15," Dan O'Boyle, spokesman for Program Executive Office Missiles and Space, said in a written statement.
As the principle manufacturer of HELLFIRE missiles, the Army provides the weapon to national and international entities to include the Marine Corps, Air Force and Navy arsenals, among others. Overall, there as many as 15 or more international customers using HELLFIRE missiles, many of them partners in the U.S.-led coalition to destroy ISIS.
While Army officials did not provide specific numbers of production increases or plans to provide particular allied nations with HELLFIREs, the Pentagon has requested $1.8 billion in its 2017 budget for munitions, bombs and missiles needed to replenish or maintain stockpiles and sustain the attacks against ISIS.
As part of a separate effort, the Air Force did request and receive $400 million in reprogrammed dollars to address an air-to-ground munitions shortage, particularly with Hellfire missiles.
"The Air Force worked with the Army to re-prioritize HELLFIRE missile deliveries to the Air Force, requested additional funding for HELLFIRE missiles, reduced aircrew training expenditures, and is working a procurement plan to increase production to reconstitute munitions stocks as quickly as possible," an Air Force official told Scout Warrior.
While precision-guided air-to-ground weapons are typically needed during aerial bombing efforts, they are of particular urgent value in the ongoing attacks on ISIS. ISIS fighters regularly hide among civilians and at times use women and children as human shields, making the need for precision all the more pressing.
In service since the 1970s, HELLFIRE missiles originated as 100-pound tank-killing, armor piercing weapons engineered to fire from helicopters to destroy enemy armored vehicles, bunkers and other fortifications.
In more recent years, the emergence of news sensors, platforms and guidance technologies have enabled the missile to launch strikes with greater precision against a wider envelope of potential enemy targets.
HELLFIRE Missile Technologies and Platforms
These days, the weapon is primarily fired from attack drones such as the Air Force Predator and Reaper and the Army's Gray Eagle; naturally, the HELLFIRE is also used by the Army's AH-64 Apache Attack helicopter, OH-58 Kiowa Warriors and AH-1 Marine Corps Super Cobras, among others. Although not much is known about when, where or who -- HELLFIREs are also regularly used in U.S. drone strikes using Air Force Predators and Reapers against terrorist targets around the globe.
The HELLFIRE missile can use radio frequency, RF, guidance – referred to as "fire and forget" – or semi-active laser technology. A ground target can be designated or "painted" by a laser spot from the aircraft firing the weapon, another aircraft or ground spotter illuminating the target for the weapon to destroy.
There are multiple kinds of HELLFIRE warheads to include a High-Explosive Anti-Tank, or HEAT, weapon and a Blast-Fragmentation explosive along with several others. The HEAT round uses what's called a "tandem warhead" with both a smaller and larger shaped charge; the idea is to achieve the initial requisite effect before detonating a larger explosion to maximize damage to the target.
The "Blast-Frag" warhead is a laser-guided penetrator weapon with a hardened steel casing, incendiary pellets designed for enemy ships, bunkers, patrol boats and things like communications infrastructure, Army documents explain.
The "Metal Augmented Charge" warhead improves upon the "Blast-Frag" weapon by adding metal fuel to the missile designed to increase the blast overpressure inside bunkers, ships and multi-room targets, Army information says. The "Metal Augmented Charge" is penetrating, laser-guided and also used for attacks on bridges, air defenses and oil rigs. The missile uses blast effects, fragmentation and overpressure to destroy targets.
The AGM-114L HELLFIRE is designed for the Longbow Apache attack helicopter platform; the weapon uses millimeter-wave technology, radar, digital signal processing and inertial measurement units to "lock-on" to a target before or after launch.
The AGM-114R warhead is described as a "Multi-Purpose" explosive used for anti-armor, anti-personnel and urban targets; the weapon uses a Micro-Electro Mechanical System Inertial Measurement Unit for additional flight guidance along with a delayed fuse in order to penetrate a target before exploding in order to maximize damage inside an area.
The AGM-114R or "Romeo" variant, which is the most modern in the arsenal, integrates a few additional technologies such as all-weather millimeter wave guidance technology and a fragmentation-increasing metal sleeve configured around the outside of the missile.
The "Multi-Purpose" warhead is a dual mode weapon able to use both a shaped charge along with a fragmentation sleeve. The additional casing is designed to further disperse "blast-effects" with greater fragmentation in order to be more effective against small groups of enemy fighters.
"The "Romeo" variant is an example of how these efforts result in a more capable missile that will maintain fire superiority for the foreseeable future," O'Boyle said.
Additional HELLFIRE Uses
Although the HELLFIRE began as an air-to-ground weapon, the missile has been fired in a variety of different respects in recent years. The Navy has fired a Longbow HELLFIRE from a Littoral Combat Ship, or LCS, to increase its lethality; the Navy's 2017 budget request asks for Longbow HELLFIRE missiles, beginning with the LCS surface-to-surface mission module, Navy officials told Scout Warrior. Also, the Army has fired the weapon at drone targets in the air from a truck-mounted Multi-Mission Launcher on the ground and international U.S. allies have fired the HELLFIRE mounted on a ground-stationed tripod.
