Problem is the bombers are intercontinental. Which means even if you hit all the bases within 2000km they are not bothered by it. The bombers were design to fly halfway around the world and come back. Especially during the Cold War. Many missions have happened like that.do you knew how many b-2 or f-22 were supposed to be built and how many actually built . and as i said those bomber won't come near iran the release their missiles 2000+ km away . my question is when your radar detect them when your interceptor fly and by what spped they fly , how long it take them to reach the bombers ? can they reavch them at all.
on intercepting those bombers well I believe you cant intercept them in the sky in time , but you can hit them on the ground at their base and that's what you must have plan for
