Don't think you can make 10,000 UAVs for half a billion, much less nuclear ones. And folks would get VERRRRRY curious when you tried to make 10,000 compact nuke warheads...
Besides, there has been an answer to massed aircraft attacks for decades - nuclear SAMs. And even if the nuke doesn't get all of 'em, the EMP will do wonders for their control systems.

DoD? No way. They have to overengineer it into an F-15 equivalent.
Private companies? Sure. $50,000 a pop sounds like a pretty fair price for a small unmanned plane with a bunch of electronics.
Nuke part? I agree. Putting nukes on an unmanned vehicle sounds ... whacked.
