Israel learned from Iran's missile attacks that it needs far more interceptors than expected. 'It's a race,' missile chief says.

Multiple rounds of fighting with Iran showed Israel needs far more missile interceptors than it expected, so officials are racing to boost stockpiles.
Israel’s Arrow system (Arrow 2/3) can even knock missiles out in space and has maintained a >90% interception rate in recent conflicts.
Global interceptor supplies are strained as Iran can produce lots of missiles and the US and industry scramble to ramp up Patriot and other interceptor production.
