China 'successfully' tests radar cross section for fighter jets

May 23 (UPI) -- China continues to test stealth technology that could be used on the design of its fifth-generation fighters, according to state media.
The Global Times reported Tuesday Shenyang Aircraft Corp., a subsidiary of the Aviation Industry Corp. of China, had successfully tested a Radar Cross Section.
The report, quoting a military technology magazine, marks the first time the Chinese government has disclosed development of RCS.
China has pledged to develop a military that will surpass that of the United States by 2050.
RCS is the measure of a target's ability to reflect radar signals in the direction of the radar receiver.
Only the United States, Russia and the European Union are proprietors of the technology.
Military analysts said the technology has been applied to China's J-20, a fifth-generation fighter jet.
The J-20 is competitive with the United States' F-22 Raptor, a stealth tactical fighter aircraft, and the F-35 Lightning, a multi-role fighter.
"The J-20 is built by Chengdu Aircraft Industry Group, and Shenyang Aircraft Corp. is also conducting research and development of another China-made stealth fighter, the FC-31, so the technology is very basic and essential," said Song Zhongping, a commentator with Phoenix TV.
"If the RCS test can be used maturely, that means the fourth-generation fighter jets, including the J-11 and J-16 that form the main body of the Chinese air force and are produced by Shenyang Aircraft Corp., can also improve their stealth capabilities."
China has been strengthening its military presence in the South China Sea and also asserting itself diplomatically vis-à-vis the United States.
Beijing foreign ministry spokesman Lu Kang said Wednesday the Chinese government has been playing an active role in North Korea negotiations, South Korean news service Newsis reported.
Lu was responding to questions regarding Trump's criticism of Chinese dealings with North Korea and the second summit between China's Xi Jinping and Kim Jong Un.
