The BLU-108/B submunition is currently produced for the SFW (NSN 1325-01-8801), a wide-area munition in the 1000-pound class. The BLU-108/B submunition weighs approximately 60 pounds, contains four warheads, and orientation and stabilization system, a radar altimeter, and a rocket motor. Each warhead fires an explosively-formed projectile triggered by a two-color infrared sensor. At a preset altitude sensed by a radar altimeter, a rocket motor fires to spin the submunition and initiate an ascent. The submunition then releases its four projectiles, which are lofted over the target area. The projectile's sensor detects a vehicle's infrared signature, and an explosively formed penetrator fires at the heat source. If no target is detected after a period of time, the projectiles automatically after a preset time interval, causing damage to material and personnel.
The BLU-108 sensor fuzed submunition was developed by the U.S. Air Force in partnership with Textron Systems as part of the Sensor Fuzed Weapon (SFW) air-to-ground strike munition. The proven efficiency and continued product enhancements have also made BLU-108 the submunition of choice for the U.S. Air Force and U.S. Navy AGM-154B Joint StandOff Weapon (JSOW). The SFW, with its versatility, lethality and redundant self-destruct features, make it the weapon of choice for the 21st century war fighter.
In production since 1992, the original baseline BLU-108, as part of the Sensor Fuzed Weapon, has exceeded U.S. Air Force lethality requirements. More than 200 live tests have demonstrated the effectiveness of the SFW and BLU-108 in defeating a variety of combat vehicles.
The BLU-108 contains 4 smart Skeet warheads. The Skeet's Explosively Formed Penetrator (EFP) is the lethal component of the warhead. The one pound copper EFP, moving at hypersonic speeds, performs a kinetic energy kill of the target, thus minimizing collateral damage.
Today's improved Skeet warhead incorporates a fragmentation ring to defeat soft targets and their ancillary equipment. The Skeet's center core projectile is designed to defeat heavy armored vehicles. Effective against both hard and soft targets, the BLU-108 target set includes:
* Main battle tanks
* Mobile missile launchers
* Air defense sites
* Parked aircraft
* Armored personnel carriers
* Littoral targets
Redundant self-destruct functions designed into each Skeet warhead allow for clean battlefield operation.
Each Skeet has two built-in self-destruct features to help reduce the risk of unexploded ordnance being left on the battlefield. A timeout feature instructs the Skeet to self-destruct within seconds if a valid target has not been detected. An altitude feature causes detonation to happen a short distance above the ground. These important features significantly reduce the potential for unexploded ordnance on the battlefield-an issue for many older submunition products.
Unlike older, traditional "cluster" weapons, each Skeet warhead features built-in, redundant, self-destruct logic. If the Skeet warhead does not detect a valid target over its lofted trajectory, it will self destruct. Each warhead also contains a timed self-deactivation mode which denies explosive activation should the self-destruct feature not occur. These safety features minimize post air strike hazards to non-combatants and civilians.
The BLU-108 is capable of integration into a number of weapon systems:
* BQM-109 Tomahawk, Raytheon Systems
* SM-2 Land Attack STANDARD Missile, Raytheon Systems
* MGM-140 Army Tactical Missile System (ATACMS). Lockheed Martin
* AGM-84H Standoff Land Attack Missile - Expanded Response (SLAMER), Boeing
* AGM-158 Joint Air-to-Surface Standoff Missile (JASSM), Lockheed Martin |
