BLU-122/B, A/B Penetrator Warhead

The BLU-122 warhead is a 5000 lb class weapon designed to defeat hard and deeply buried targets. It significantly improves upon the performance of the BLU-113 warhead by incorporating the latest technological advances in warhead designs and explosives. The new warhead also incorporates design improvements to improve its insensitive munition performance. The latest GBU-28 variant delivers the warhead using a Laser / INS / GPS guidance system. It will be employed on both the B-2A and F-15E aircraft.

The Air Force is improving capability to attack hardened and/or deeply buried targets during adverse environmental conditions. The performance of the current 4,700-lb BLU-113, used on the GBU-28 GPS/laser-guided bomb, is being greatly enhanced through the design modification of the BLU-122 warhead, improving its penetration, lethality, and survivability. This modification will increase the number of deeply buried targets held at risk. In addition, some existing targets held at risk will require fewer weapons, therefore reducing the number of missions necessary to defeat a target.

The MIL-STD 1760 conduit will also be extended to connect the guidance system to the fuze to support a future in-flight fuze reprogramming capability. The existing GBU-28 B/B--B-2 interface will be maintained and the GBU-28 will also be integrated onto the F-15E through the Joint Direct Attack Munition (JDAM) Smart Unknown Weapon Interface. This program was a NEW START in FY03. The program is in Budget Activity 04 (BA 04) because the program will develop and demonstrate a hard target munition capability to defeat hard and deeply buried targets not currently held at risk. This program entered initial production during the last two quarters of FY05.

General Dynamics Ordnance and Tactical Systems, Niceville, Fla., was awarded on May 31, 2005 a $5,204,682 firm fixed price contract modification to provide for BLU-122 production warheads, quantity of 71. This is the first production lot for the BLU-122 warhead, which emerged from the BLU-113 Pre-Planned Product Improvement (P3I) program. The BLU-122 provides the Air Force capabilities to hold more targets at risk than the BLU-113 and generally improve the penetrability, survivability, and lethality. This contract modification also obligates funds to support implementation of the Unique Identification and Valuation requirement. The locations of performance are FAXON Machine, Cincinnati, Ohio, and Superior Forge and Steel, Lima, Ohio. Total funds have been obligated. This work was to be completed by March 2006. Solicitation began April 2005 and negotiations were completed May 2005. The Air Armament Center, Eglin Air Force Base, Fla., is the contracting activity (F08635-03-C-0025, P00005).
