The NYT is all a-gush about China’s increasing transparency and military prowess:
The J-15 Flying Shark is China’s newest attack jet, a sinuous fighter with the folding wings, shortened tail cone and bulked-up landing gear it needs to serve on China’s first aircraft carrier, which is expected to start sea trials soon. It is indisputable evidence of China’s growing mastery of military technology.
The machine was reverse-engineered from an Su-33 imported from the Ukraine after the Russians refused an export license. It’ll have shorter legs than even the FA-18 (!) because of the ski jump take-off CONOPS. And the Chinese have yet to operate a high performance aircraft off the deck of an aircraft carrier, which trust me, is harder that it looks.
“Mastery,” you keep using that word. I do not think it means what you think it means.
