BLU-111/B

The BLU-111 General Purpose bomb is identical to the MK82 MOD 2 bomb, with the exception of the PBXN-109 explosive filler. The primary users are the U.S. Air Force and U.S. Navy. This bomb has a slender body made of steel with a well in the nose section for a proximity sensor, mechanical fuze and adapter booster, or a penetrating nose plug; and a well in the aft section for a tail electric fuze. It uses either a conical, non-retard, or retarding fin, or laser/GPS guidance airfoil kit, or a mine kit.

The BLU-111/B penetrator is forged steel casing warheads, which is a more accurately toleranced variant of the MK-82, 500-pound general purpose bomb. The Joint Standoff Weapon AGM-154C (Unitary Variant) will use a combination of an Imaging Infrared (IIR) terminal seeker and a two-way data link to achieve point target accuracy through aimpoint refinement and man-in-the-loop guidance. The AGM-154C will carry the BLU-111/B equipped with the FMU-152 Joint Programmable Fuze (JPF) and is designed to attack point targets.

Some bombs are thermally protected for use on aircraft carriers. The thermally protected MK 80 series bomb was developed to increase the cookoff time and decrease the reaction of bombs when engulfed in a fuel fire.

The BLU-110A/B and BLU-111A/B thermally protected bombs are identical to the MK 83 and MK 84 thermally protected bombs, respectively, with the exception of the explosive filler. The BLU series bomb bodies use PBNX-109 as explosive filler. The MK 82 and MK 83 series LDGP bombs underwent a Product Improvement Initiative (PII) which entailed filling the bomb cases with a less sensitive explosive. When so filled the MK 82 and MK 83 bombs are redesignated BLU-111/B and BLU-110/B, respectively.
