J-31: The latest Chinese stealth fighter, the J-31 will undoubtedly be the star of this year's Zhuhai Airshow. The J-31 has already arrived in southern China to prepare for the airshow. The J-31, designed and built by Shenyang Aviation Corporation, is a 20-ton, twin-engined stealth fighter, about the same size as the American F-35. Once it enters service, the J-31 would serve as a medium fighter alongside the heavier J-20, as well as on China's future carriers. While the J-31 is currently still in the technology demonstrator phase with minimal avionics and interim engines, China is hoping that its airshow debut could draw interest from Arab nations unable to purchase the F-35, as well as Pakistan and Latin America.
