I don't believe it will be difficult to add passive inertial guidance and optical recognition capability to existing drones. This capability is nearly at the hobbyist level today -- if it's not already.The ones being used now are dependent on chinese GPS satellites for navigation and targeting which apparently did not stand up to the mil spec quality of US equipment and failed to survive US active signal jamming where it was used. As has most chinese supplied electronic military equipment. Made in China has become true disaster in most cases... We kinda gave china a peek at our hand and they are worried about their future endeavors.
Throw in some cheap Chinese solar power, and the range could be indefinite.
Later, throw in some stealth as the tech becomes available to them.
