Blu-109 Bomb
The BLU-109/B is a hardened 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.

Design
The BLU-109/B has a steel casing about 1 inch (25 mm) thick, filled with 530 pounds (240 kg) of Tritonal. It has a delayed-action tail-fuze. 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-27 Paveway III laser-guided bomb, and the AGM-130 rocket-boosted weapon. This weapon can penetrate 4–6 feet (1.2–1.8 m) of reinforced concrete, which is greater than the 3 feet (91 cm) capability of the Small Diameter Bomb.
Variants
The BLU-118 is reportedly a thermobaric explosive filler variation on the BLU-109 casing and basic bomb design. It contains PBXIH-135, a traditional explosive.
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 have evolved out of the Small Business Innovation Research (SBIR) program by Exquadrum, Inc. of Adelanto, California.
