I’m sure drones have our war planners lying awake at night.
Sending 100 tanks that cost $15 million each into battle and having them all wiped out by 3-400 drones that cost maybe $200 each tops is going to be a significant tactical consideration.
The times they are a changin’
Most of a Strategic Airlift Wing could be destroyed right now, from a Waffle House parking lot, by 1 guy with a pickup and off-the-shelf engineering.
It's 1 mile. It could be done with 3d printed drones we were playing with in 2009. Nowadays the average racing multirotor drones are 20mph faster than they were then, with world records around 230mph. I had (I killed it) an 80" fixed wing fpv drone with gps, laser altimeter, etc, using a system called Ardupilot that could fly 15 miles away on 433mhz controls + return to home on signal loss that would only need a minor refit for modern electronics to be a pretty good artillery spotter. I have a 100" model called an Anaconda which I'm fairly sure has seen action in Ukraine, it can haul cameras for 2 hours on retrofitted laptop batteries.
Given the size of an RPG-7 round and a swing-arm drone body to accomodate it, you can pack probably 300 of pnuematic launch tubes in the back of a pickup truck, 15 wide x 20 deep. That should be sufficient to make every aircraft their combat ineffective. Even easy to make them talk on wifi at that range and divide up targets using their machine vision.
