The BLU-110 General Purpose bomb is identical to the MK83 MOD 5 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 or retarding fin, or laser/GPS guidance airfoil kit, or a mine kit.

Hard Target penetrators being changed into low-cost Joint Direct Attack Munition [JDAM] include the 2,000 pound BLU-109 and 1,000 pound BLU-110 forged steel casing warheads, which are more accurately toleranced than the Mk.80 series. JDAM consists of a tail kit that can be attached to 'dumb' free-fall gravity bombs that have been in the Air Force and Navy inventories for decades, turning them into accurate guided 'smart' bombs. The heart of the tail kit is an Inertial Navigation System/Global Position System, or INS/GPS, guidance system that gives JDAM an all-weather capability and high accuracy.

Some 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.
