The Mk 82 is the warhead for the GBU-12 laser-guided bombs and for the GBU-38 JDAM.
Currently the Mk 82 bomb body is manufactured by 17 plants worldwide. Currently only the General Dynamics plant in the Garland, Texas is DoD certified to manufacture bombs for the US Armed Forces.

[edit] Variants
- BLU-111/B- Mk 82 loaded with PBXN-109 (vs H-6); item weighs 480 lbs..[1] PBXN-109 is a less sensitive explosive filler.[2] The BLU-111/B also is the warhead of the A-1 version of the Joint Stand-Off Weapon JSOW.
- BLU-111A/B- Used by the U.S. Navy, [3] this is the BLU-111/B with a thermal-protective coating added[4] to reduce cook-off times in (fuel-related) fires.
- BLU-126/B- Designed following a U.S. Navy request to lower collateral damage in air strikes. Delivery of this type will start no later than March 2007. Also known as the Low Collateral Damage Bomb (LCDB), it is a BLU-111 with a smaller explosive charge. Non-explosive filler is added to retain the weight of the BLU-111 so as to give it the same trajectory when dropped.[5]
