I guess it is a good thing then that this isn't something they actually do.
They use cheap weapons to shoot down cheap drones. Their primary anti-drone missile was developed in the 2010s and costs less than a Shahed.
Which is the same reason no level of military power is going to keep the Strait of Hormuz open (or at least, no level beyond a truly absurd one and even then - see the Kerch bridge in Crimea).
But Orange Dementia didn't even think about that.
The US took the old Vietnam-era unguided rocket pods (Hydra 70), of which they produce hundreds of thousands every year, and slapped a dirt-cheap guidance kit to the front of each rocket. Supposedly 90-95% effective. A bunch of countries are developing their own clones of the concept.
A single F-16 can carry 42 missiles. They've been rapidly expanding the number of platforms they can attach these to.
