I agree this probably is a lie for propaganda, but its also true that drones are easy to produce for a cheap cost and Iran has underground facilities to produce them that have not been taken out. Destroying Iran’s drone producing capacity is going to be tough. This seems to me to be the biggest challenge of the war right now. Even if we completely destroy their nuclear, missile and naval capacity, Iran could get their drone producing capacity back up and running and start lobbing drones at Israel and Iran’s other neighbors in the short term. And Israel and the neighbors would have to shoot down $30,000 drones with $1 million missiles.
Those drones can be shot down with a short 2 second 20mm auto cannon burst from a jet or attack helo ( for the really slow drones like the ones shown in picture)
How do you get the production workers to show up when they know that they will eventually be targeted?
A lot of those drones are prop driven jobs & not very fast. Attack helicopters could shoot them down fairly easily, I would think. I don’t know how stealthy they are though. They may be difficult to pick up on radar, especially if flying low.
