You use the word easily so many times here where it becomes more and more apparent that you probably don’t think it means what it means
I’ve worked with drones of various sizes. Bigger and more expensive ones are more capable, but hard to make bullet proof. If you can remote off their sensors and weapons into cheap, more disposable systems, it makes sense.
A big drone, like a predator, drops a package into an area. Mid sized multicopters provide local computing power and coordination. Small planes provide fast loiter surveillance. Small multicopters with cameras give more accurate coverage. For attack, you have what amounts to a hand grenade with props. Protection takes the form of similar disposables. A flying strobe light to mess up optical tracking. Chaff bombs to mess up radar tracking. Smoke to obscure the high value units.
A lot of these I could throw together myself, given a few weeks, and a few grand. What part wouldn’t be easy, for a large and well funded military r&d team?
What part wouldn’t be easy? The hand grenade with props. The strobe light. The chaff. The software. The batteries and power supply. The reliability. The compute requirements. There is so many things that are easy sounding to you because you romanticise the idea but it’s not easily done at all
Easy for a remotely advanced military force.
An explosive drone is easy. Just a small amount of high explosives and an electronic detonator.
Strobe lights could just be an overdriven LED. It just needs to dazzle optical sensors for a few seconds.
Chaff is just lightweight foil. It’s effectively an oversized party popper. It’s job is to help overwhelm radar based tracking.
Software is the hardest bit. At the same time, many computer game ‘AIs’ are good enough at this they need to be dumbed down significantly. It would be more specialised, but only needs to be written once, then rolled out to a fleet.
Batteries would be a swarms limiting factor. Single shot lithium would likely be the bulk. 5-20 minutes of flight, then it’s dead. Disposables would likely need to be moved into position by other means, either a dedicated transport drone, ground transport, or air drop. Your transport doesn’t need to stay in the combat zone however, it can bug out and be reused. Larger more specialist systems would land and loiter to save batteries, and/or be fuel cell powered.
Reliability is handled by numbers, losing 10% is fine, when you have 20% extra.
Computing requires would be met by something like Nvidia’s Jetson range. They are designed for low power, low weight AI processing. Putting a tflop of computing power in the close Comms loop would be simple. The controller would be the most expensive part of the swarm. Not only would it need enough power, both computing and electrical, but also significant Comms capabilities. Radio links, with optical backup would be the workhorse. With a mesh setup, including dummies to help hide it’s location. This is similar to how the display drones work. An expensive hub, serving a cheap swarm.
While none of this is “easy” for a random guy in a shed, or a terrorist in a cave, it’s child’s play compared to a lot of the tech the US can deploy.
