American aircraft designers have unveiled a unique unmanned refueling tank.

The night before it became known that the American aircraft manufacturing company Boeing presented to the world its first unmanned aerial vehicle capable of refueling combat fighters and bombers in the air. Initially, there was evidence that we are talking about a unique unmanned bomber, which, incidentally, did not find official confirmation until today, and in fact, the appearance of a UAV refueling in the air did not produce any furore.

At the moment, it is known that the unmanned aircraft Boeing MQ-25 Stringray passes all the necessary tests, and sending it to the troops is scheduled not earlier than at 2020.

It is reported that the drone can carry on board up to 6800 kilogram of fuel, however, the effective range of this UAV is limited to a distance of 900 kilometers.
