Summary and Key Points: China's Chengdu J-20 "Mighty Dragon" and the forthcoming Shenyang FC-31 stealth fighters are widely believed to incorporate stolen design elements from American and likely Russian fighter programs.

-In particular, a Chinese national named Su Bin was found guilty of conspiring to steal sensitive military information, including the designs for the F-22 and F-35, for the Chinese military.

-The J-20's development, influenced by this stolen technology, showcases China's efforts to quickly bridge the gap between its military capabilities and those of the United States. Despite the theft, the effectiveness of these aircraft in combat remains to be fully assessed.

It’s not uncommon to hear people say that China’s most advanced stealth fighters, the in-service Chengdu J-20 and forthcoming Shenyang FC-31, incorporate stolen design elements from existing American and Russian fighter programs. Russian allegations of copycat technology are born largely out of overall similarities between the J-20 and Russia’s long-defunct MiG 1.44 program. However, although Russian allegations leave at least some room for debate the same can’t be said for China’s theft of American stealth fighter designs.

In March 2016, a 51-year-old Chinese national named Su Bin pled guilty to charges associated with what the American Justice Department described as a “years-long conspiracy” conducted in concert with high-ranking members of the Chinese military to steal American military secrets – most notably, the designs for advanced stealth fighters like the F-22 and F-35.

“Su admitted that he conspired with two persons in China from October 2008 to March 2014 to gain unauthorized access to protected computer networks in the United States – including computers belonging to the Boeing Company in Orange County, California – to obtain sensitive military information and to export that information illegally from the United States to China,” reads the Justice Department release.

Su Bin, who worked in Canada under the name Stephen Su, was a well-regarded businessman and entrepreneur in the aviation industry, serving as the sole proprietor of a small company that specialized in aircraft cable harnesses. This company, called Lode-Tech, was described by the Air Force Office of Special Investigations as a “small player” in the field, with only a handful of employees and limited access to broader aviation programs.

However, despite the minimal reach of Lode-Tech, Su Bin........
