Can I ask if you are working with any established US defense-oriented electronics firms that go further up the supply chain in auditing/documenting sources and chain of custody of components and the whole BOM? Having US made circuit boards is great but if a certain model of microcontroller only comes from one or two sources and they're in mainland CN, that's a known caveat that has to be documented somewhere... Or if the same product is available at a higher price from a different location. That sort of thing.

One example I could offer is APD, the ESC manufacturer in Australia. They sell ESCs used both in the commercial cinema/filming industry (big quads and coaxial octos carrying RED Komodo size cameras), but also for defense...
