The BLU-117 General Purpose Bomb is identical to the 2000lb class MK 84 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 electronic fuze. It is compatible with proximity sensor and mechanical/electrical/electronic fuzes. It uses a conical fin or laser/GPS guidance airfoil kit or mine kit.
The BLU-117/B is a 2000 lb penetrator Bomb/Warhead similar to Mk84, which is used in the GBU-10 Paveway II. The BLU-117 is the current GP bomb filled with the Insensitive Munition (IM) explosive PBXN-109 currently used by the US Navy.
