Why an interceptor can cost a hundred times the drone it downs
The cost-exchange problem, from a $4 million PAC-3 MSE round to tens-of-thousands-of-dollar drones — and how defenders are re-tiering their magazines.

Surface-to-air systems explained layer by layer: sensors, interceptors, command links, magazine depth and the cost per engagement each design accepts.
Magazine depth is the number that decides an air defense battle before it starts
Every interceptor fired is inventory that cannot be replaced in days, and attackers have learned to count.
Terrain and siting decide what a ground radar can and cannot see
A radar's coverage is a line-of-sight calculation before it is a performance number — hills, horizon, and antenna height cut the published range down to a site-specific shape.
How C-RAM defenses shoot down rockets, artillery and mortar rounds in mid-flight
The hardest target in air defense is not an aircraft but a small, cheap, ballistic lump of steel on a 60-second flight.
Why low-flying cruise missiles vanish from ground radar and how airborne cueing finds them
The Earth itself is the first stealth coating: below the radar horizon, a cruise missile is invisible until seconds matter.
An engagement zone is smaller than the missile: how defenders size it
The advertised range of an interceptor is where its box begins, not where it ends — engagement zones are cut down by geometry, timing, and kill probability.
