Rövid kis összefoglaló a J-20-ról és az J/FC-31-ről.

"Both aircraft show that PRC’s aerospace industry is now capable of emulating the external design forms of stealthy U.S. fighters. What remains to be seen is how advanced the aircraft’s materials are, as well as how capable their on-board systems. “These are the factors in modern fighter design that make all the difference,” said a U.S. defense industry representative. “You cannot copy these or make them appear to be ‘the same as’ those of U.S. aircraft. And they will make the difference in how effective these airplanes are.”
