Rumor has it that Azerbaijan has bought four Iron Dome missile defense systems from Israel. If confirmed, the purchase would signal Baku's continuing preparations for a wider conflict with its neighbor, Armenia, down the road. On Oct. 4, an Azerbaijani lawmaker told local media that Israel had sold the weapons systems to Baku, though a delivery date was not specified. The statement appears to confirm previous reports that Azerbaijan had signed a contract with Israel for four Iron Dome batteries. The systems have proved effective in defending Israel against low-caliber rocket artillery and mortars in the past. Their deployment to Azerbaijan would likewise provide it with some defense against similar projectiles — a sought-after capability for Baku, considering that mortar and artillery shelling has become the daily norm on the front lines of its enduring dispute with Armenia over Nagorno-Karabakh. But the Iron Dome system is not without weaknesses.
