His risk management strategy is to have redundant everything, so there's no single point of failure. Lots of small drones. Distributed operators. Many small factories. Varied command and control systems. He makes the point that they use lots of different kinds of drones - some fast with wings, some slow with rotors, some that run on treads on the ground. There's no "best drone". Using multiple types in a coordinated way makes it hard for the enemy to counter attacks. No one defense will stop all the drones.
Ukraine built 4,000,000 drones in 2025. This year, more. The Ukrainian military needs a new generation of drones about every three months, as the opposition changes tactics. They view most US drones as obsolete, because the product development and life cycle is far too long. (See "OODA loop" for the concept.)
This is a big problem for the US military's very slow development process. Development of the F-35 started over 30 years ago.
