China may be testing a new, long-range air-to-air missile that could take out early warning aircraft and aerial refueling aircraft, a state-run newspaper said on Thursday, after pictures of the new missile surfaced online.

President Xi Jinping is overseeing an ambitious military modernization program that includes stealth jets and aircraft carriers. The country has also tested anti-satellite missiles.

The official China Daily said the People's Liberation Army had recently posted pictures online of a J-11B fighter carrying a large, unidentified missile during drills last year.
