So now the camera is pointed at the target? How is it checking that the other drones are headed in the right direction? And the personnel on the ground? They're just chillin' waiting for those other drones to come intersect with the stationary spotter drone's line of sight?
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.
