We have two years of footage from Ukraine, where camera-equipped drones are launched from a several miles away at most, and where there are networks of pilots and support specialists to assemble and launch more drones in case of (frequent) failure.
I don’t think it’s wise to wager the success of a 6-month mission deep in enemy territory on a plan with a single point of failure, especially when the alternative is equipping each drone with < $100 cameras.
We've had two years of footage of drones being flown over tanks, and bombs dropped directly down into them.
