Description
The BLU-109 entered service in 1985. Development of a variant designated HAMMER began in 2015.
The BLU-109 is a penetration bomb designed to defeat concrete shelters and hardened structures. The munition features a steel casing and a tritonal explosive filler. It utilizes a mechanical-electrical delayed-action tail-fuze to ensure detonation occurs after target penetration. The BLU-109 serves as the warhead component for several guided weapon systems, including the GBU-15 electro-optically guided bomb, the GBU-24 and GBU-27 Paveway III laser-guided bombs, the GBU-31 Joint Direct Attack Munition (JDAM), and the AGM-130 air-to-surface missile. A variant designated the BLU-118 utilizes the same basic casing and design but incorporates a thermobaric explosive filler.
The system is widely deployed and has been produced in large quantities. It is operated by the United States Air Force and is part of the armament of numerous international air forces. Operators include Australia, Belgium, Canada, Denmark, France, Germany, Greece, Israel, Italy, Morocco, the Netherlands, Norway, Pakistan, Saudi Arabia, Serbia, South Korea, Turkey, the United Arab Emirates, and the United Kingdom.
