Note that there are several drone microcontroller manufacturers based in the U.S. right now - ModalAI, ARK Electronics, Rotor Riot, etc.

The thing about drones is that they actually don't require much computational power compared to modern consumer computing. It's just math - control systems, calculus, trig, waypoints, etc. All of these were solved problems in the days of the Apollo Guidance computer, and will run comfortably on chips from 2 decades ago. The STM32F722 microcontroller that is one of the most common hobbyist drone chips is built on the 90nm process node, runs at 216MHz, has 512K of SRAM, and costs about $5/chip. FWIW, it's made in France and Italy rather than China, and STMicroelectronics owns its own fabs rather than outsourcing to TSMC or Chinese companies.

If you want to do things like computer vision on the drone, the computational requirements are quite a bit higher, but you can still run something like YOLO at orders of magnitude less computational power than what you've got in a Pixel 9 or iPhone 16.

...which makes me wonder if a better strategy for the military would be to fund a wide variety of domestic chip manufacturers operating at decades-old process nodes (eg. the 65nm process node from 2005 seems to be at about the sweet spot), rather than try to prop up the one American company that can compete on cutting edge 7nm process nodes. Particularly since the experience of WW2 was that simple, robust designs that could be easily licensed to other suppliers and mass produced (eg. the Hawker Hurricane, Grumman F6F Hellcat, Grumman/GM TBF Avenger, Liberty ship, escort carrier) were much more effective at turning the tide of battle than designs that were on the cutting edge of technology (eg. the Vought F4U Corsair, Gloster Meteor, Japanese Shinano aircraft carrier). The latter were often better in absolute performance, but arrived late, in small numbers, and with teething troubles that made the former carry the bulk of the battle. The Liberty Ship, for example, used reciprocating steam engines that were 50-year-old technology in WW2, but they were "good enough" and dead simple to make.
