I doubt that there will be more than some technology demonstrators in less than four years.

And everyone is forgetting that with small size comes small range and payload. Small range means your opponent has to get close to you, exposing themselves. The article has some huge assumptions, at least concerning attacking a naval ship (which is far easier than an aircraft that can outperform a drone). The idea that an Aegis cruiser is going to let a fishing boat launch a significant number of drones without getting perforated by its MK-45 is a non-starter.
