basically a smaller sized unmanned b2. Again iran cant do shit with it, only russians and chinese, their allies, can. But to be honnest, russians already have the almost equivalent stuff, and chinese arent that far either, considering both are trading their knowledges they stole or developed, constantly. It's the electronics that will be dessicated by chinese and russians engeeners, thus allowing them to make quicker progresses to improve their own unmanned drones.
The us army still is by far the biggest and most advanced army in the world with the better trained soldiers.
It's funny how all these events happen at the same time economies are going down tho.
