A photo recently revealed on the internet shows that a J-20 stealth fighter was flying in the air with a Y-20 refueling tanker for a refueling test, marking research and development for Y-20 refueling tanker is progressing smoothly and has entered its critical final testing stage.
The picture shows the Y-20 tanker is using hose refueling technology, according to analysis, this means that the Chinese air force and naval aviation has adopted the international common hose-cone sleeve air refueling technology as a standard, while hard-tube aerial refueling widely expected by the Chinese military fans will have no chance with China.
