The news is outright wrong about that. Yes, as a last ditch measure patriots etc are used to shoot down leaker drones, but the primary weapon systems to take down the slow moving drones are APKWS rockets on fighters, and helicopter gunships using cannon fire.

There is definitely an argument to be made that even APKWS is too expensive due to the cost of flying a F16 per hour, but it’s not at the level of a few million dollar missile.

Obviously the US was in no way prepared for the Iranian response, but it’s not like zero development has happened in the last few years. It’s far too slow, but it’s deployed and in active use in combat. Hopefully this will be a wake up call that military procurement and domestic manufacturing needs to be wholesale reconfigured with breakneck speed. Doubtful though without much more pain felt directly by American citizens.
