The notification covers the proposed transfer of 3,845 KMU-558B/B guidance kits for BLU-109 bombs and 3,280 KMU-572F/B kits for MK 82 bombs. Additionally, the deal comprises engineering, logistical and technical support services from the US government and contractors, as well as related support components.
According to the announcement, the sale “is consistent with U.S. national interests and supports Israel’s ability to maintain a high level of combat readiness.” It also noted that the equipment will “improve interoperability with U.S. forces and reaffirm Washington’s commitment to maintaining Israel’s military edge.”
The deal comes in the aftermath of Israel’s intensive air campaign against Iran conducted between 13 and 24 June, during which several thousand munitions were reportedly dropped. A significant portion of these were JDAM-guided bombs, including bunker-busting variants.
The KMU-558B/B guidance kit is designed for integration with the BLU-109 penetrator bomb, which weighs around 2,000 pounds (approx. 907 kg) and is built to destroy fortified structures such as bunkers, shelters, and command centres. The kit includes an inertial navigation system (INS), GPS receiver, control surfaces (fins and flaps), and bomb mounting components, enabling the BLU-109 to strike targets with metre-level accuracy in all weather conditions.
The KMU-572F/B kit is intended for use with the lighter Mk 82 bomb, which weighs 500 pounds (approx. 227 kg). While it performs similar functions to the KMU-558B/B, it is adapted to the distinct aerodynamic and ballistic properties of the Mk 82, allowing for precise targeting with reduced collateral damage.
