Destroyers aren't even anti-air. Cruisers are, since Cruisers have two CWIS per ship while Destoyers only have 1x CWIS.

England's https://en.wikipedia.org/wiki/Type_45_destroyer are primarily in an anti-air and anti-missile role, even.
While Modern Cruisers were closer to specializing in the air-defense role.
But yes, Destroyers have lots of anti-air on them for sure.
Additionally, ships are usually not alone. The other vessels in the battlegroup will also provide their anti-air capabilities. If they are with an aircraft carrier, then there are also planes to provide air defense.
So the enemy can always deploy more suicide quadcopter drones than missiles.

Which seems like an insanely bad strategy to me, because of the whole CIWS thing. Sure, you negate the usefulness of missiles by making drones cheaper, but you can't negate the cheapness of a CIWS, or the gatling gun of an F18 Hornet / F35B / F35C.
That's why we still use guns today: because bullets are really, really cheap.
