We'll just let Boeing build them. They have the know-how.
Plus, if we're talking military drones vs civilian drones, they wouldn't need plastic shells. That'd just be more weight reducing distance. Then again, military industrial complex would probably try to make them stealth capable, be designed by committee from 22 nation states, be micro-USB mandated to comply with EU standards, blah blah. Yeah, you're right, we'd never be able to build them here.
Boeing's expertise will come handy when it comes to designing kamikaze drones.
