Pentagon officials are pressing Congress to enhance military sales to Israel in the form of an additional $647 million package which would include 6,900 tail kits used to transform free-fall bombs into precise satellite-guided weapons and thousands of 900kg bunker buster bombs. The tail kits would supplement an Israeli arsenal already built with an emphasis on minimizing damage to non-combatants in the densely packed urban environments used for military purposes by groups such as the Iran-backed terror organization Hamas. The package also includes thousands of BLU-109 bunker busters, which are largely suited for targeting hardened command and control facilities, including air defense infrastructure.
