I have to wonder when it will switch to small, inexpensive drones instead of the larger, jet-type ones. Imagine fighting against a swarm of 10,000 drones (each with a small explosive, EMP, etc). Similar to the Fire Bats[0] in WWII.
There are examples in media!
Many mechas from the Gundam series use funnels, a form of drone, in order to overwhelm a single enemy or attack multiple ones:

Ace Combat 7 features a massive battle against an airborne UAV carrier and its swarm of drones:

Sometimes the entire screen is filled with targets!
