BLU-119/B Agent Defeat Weapon
Crash PAD

The BLU-119/B Crash PAD (Prompt Agent Defeat) weapon was developed in 2002 and delivered first as a quick reaction capability in support of Operation Iraqi Freedom in 2003. The weapon consists of a Mk 84 2,000 pound class bomb body with a payload of approximately 145 pounds of PBX-109 high explosive and 420 pounds of white phosphorus. The bomb is designed to attack chemical and biological weapon stockpiles, using the PBX-109 blast-fragmentation warhead to penetrate the weapon containers and the white phosphorus warhead to defeat the agents. The warhead is not intended to be used by itself, but instead as a warhead option for the GBU-31(V)5/B Joint Direct Attack Munition (JDAM).

The BLU-119/B was developed as part of the Defense Threat Reduction Agency's Prompt Agent Defeat (PAD) program, which began in FY02. This program responded to the 1994 US Air Force Mission Need Statement for Agent Defeat Weapons and emergent Component Command (COCOM) and Service Initial Capabilities Documents (ICDs) and was subsequently expanded into DTRA's Agent Defeat, Deny, Disrupt (AD3) program. During FY02, PAD started scale tests for agent neutralization, completed four small-scale tests for agent neutralization, and initiated a non-energetic agent defeat program, that was classified at the time. As of February 2003, it was hoped that during FY03 the PAD program would complete small-scale optimization, begin full-scale design for a PAD weapon, complete initial laboratory phase of the non-energetic agent defeat program, and begin a standardized bioassay program. In FY04, it would then provide full-scale demonstration of the PAD weapon, continue non-energetic agent defeat optimization/weaponization, and deliver modeling capability for the PAD weapon.

The weapon developed under PAD was initially known as Crash PAD. Alliant Techsystems (ATK) was awarded a $4 million contract in October 2003 from the US Air Force Research Laboratory (AFRL) at Eglin Air Force Base, Florida to develop a multipurpose "Crash PAD" bomb warhead that could be used to damage biological and chemical agent targets while minimizing environmental effects. The objective of the Crash PAD program was to demonstrate a blast/frag multi-purpose warhead that could be used to damage fixed biological and chemical targets while producing an environment that would mitigate bio-agent collateral damage. The range of applicable targets included soft to moderately hardened. Sled track testing occurred in late January 2003 and flight test occurred in late February 2003. This program was seen as having the potential to be a significant resource for the warfighter in destroying chemical and biological weapons with minimal effects to civilians.

In FY11, the Defense Threat Reduction Agency initiated concept studies for BLU-119/B conversion using a safer, lower lifecycle cost payload fill. At that time it intended to initiate testing for BLU-119/B conversion to safer, lower Life Cycle Cost payload fill during FY12.
