The maker of the J-20, China's most advanced stealth fighter jet, revealed that it recently broke records in terms of aircraft delivery due to high demand, with experts saying on Sunday that the J-20 has entered a mass production phase after it solved the last missing piece of the puzzle, the domestically developed WS-10 engine.
Now that there is no limitation caused by the import of engines, and the homemade WS-10 engine has been tested on other aircraft like the J-10, J-11 and J-16, the J-20 is in a position to start mass production, Fu said.
"In a short time, we will be able to see J-20s operated by all eastern, southern, western, northern and central theater commands, and become the main force to safeguard China's sovereignty and territorial airspace security," Fu predicted.
