The BLU-109/B is a hardened bunker buster penetration bomb used by the United States Air Force (BLU is an acronym for Bomb Live Unit). As with other "bunker busters", it is intended to penetrate concrete shelters and other hardened structures before exploding. In addition to the US, it is part of the armament of the air forces of Australia, Belgium, Canada, Denmark, France, Germany, Greece, Italy, Israel, Netherlands, Norway, Pakistan, Saudi Arabia, United Kingdom, and United Arab Emirates.[1]
Design
The BLU-109/B has a steel casing about Script error: No such module "convert". thick. Its warhead is filled with Script error: No such module "convert". of tritonal.[2] It has a mechanical-electrical delayed-action FMU-143 tail-fuze.[3]
The BLU-109 entered service in 1985. It is also used as the warhead of some marks of the GBU-15 electro-optically guided bomb, the GBU-24 Paveway III and GBU-27 Paveway III laser-guided bombs, as well as the GBU-31 Joint Direct Attack Munition (JDAM)[4] and AGM-130 air-to-surface missile.
Variants
The BLU-118 is reportedly a thermobaric explosive filler variation on the BLU-109 casing and basic bomb design.[5] It contains PBXIH-135, a traditional explosive.[6]
In 2015, General Dynamics started a $7.2 million development of a version called HAMMER, which is intended to destroy chemical and biological substances by spreading dozens of Kinetic Fireballs Incendiaries (KFI) (not explosions) inside a bunker. The KFIs evolved out of the earlier Small Business Innovation Research (SBIR) program by Exquadrum, Inc. of Adelanto, California.[7]
Operators
The BLU-109 has been sold to key US allies including South Korea, Israel, Greece, Saudi Arabia, UAE, Pakistan, and Turkey[8][9]

Operational history
In late 2023, the United States delivered 100 BLU-109 bombs to Israel.[10] Israeli F-15I fighter jets are believed to have used BLU-109s with JDAM guidance kits in the strikes that killed Hezbollah leader Hassan Nasrallah in Beirut on 27 September 2024.[11][12]
