How many TLAM guarentee a hit per target assuming X% fail in flight, Y% are shot down by the AD system (fighters and SAMs) and Z% fail to detonate?
"Y" is likely to be pretty small against any real AD defense system in the world today, certainly Iran's, that's the point; not necessarily
against any AD system we could think up theoretically, but real situations. One likely gap between theory and reality is going to be 'but they have this
AEW plane' and 'they have that interceptor' without considering the need to continuously cover the defended area 24/7 with AEW and CAP to really
down a lot of cruise missiles, whereas the missile attack is launched on attacker's timing. Another likely gap is again forgetting that against any low
flying target any SAM's effective footprint shrinks to pretty small, essentially point defense even if the SAM has much greater range v a higher altitude
target. Against a manned attack low flying will lead to planes being picked off here and there by exposing themselves to more weapons by such tactics, and the
loss rate may reach the few % Y which is intolerable to *manned* attacks in any realistic case. But a few % for Y against cruise missiles isn't anywhere
near enough. Again on numbers of ground based AD assets there's a naturally disadvantageous tradeoff for the defense: if there are lots of targets
realistic inventories can't cover them all given the short range v low altitude targets. If a few targets, expect a bunch of TLAM's all at once per
target, a quite realistic assumption. In theory or in a weapons sales brochure a modern SAM system might rapidly down a bunch of such 'easy targets',
perfectly coordinating with one another if more than one battery in the area; but in reality, with one chance to get that exactly right, it's not likely.
