Stokes said Link 16 communications are a "backbone" for advance data links for the military rooted in German Field Marshal Erwin Rommel’s North Africa campaign in World War II when a flexible system of tactical communications connected individual tanks.

Taking away Link 16 makes our defensive challenge far more difficult and makes it far more expensive in terms of casualties" in any future conflict with China. "It is the main linkage between different kind of forces and different services. "Right now Link 16 is a crucial force multiplier that allows the United States to fight jointly," he said. "It’s a fact the Chinese are developing their own JTIDS-like Link 16 system for distributed command and control operations," Fisher said, adding that an early version is probably in use now by Chinese military forces. Richard Fisher, an expert on China’s military with the International Assessment and Strategy Center, said in addition to countermeasures, China likely used the military technology secrets obtained from Bergersen to develop its own jam-proof tactical communications system. The PLA also is investing into R&D on a range of communications technologies, including tactical data links." "Satellite jamming is another area of focus. "The denial of U.S., Japan, South Korea, Taiwan abilities to employ JTIDS is only one goal," Stokes said. Mark Stokes, a former Pentagon official and specialist on Chinese military affairs said the Chinese military for years has invested large sums in electronic countermeasures technology. "So they send spies to steal what they need with the help of traitors like Bergerson who blithely sell it to them." military communications-it is at the heart of their military strategies of information dominance and anti-access/area-denial," Van Cleave said in an email. "China would like nothing better than to be able to disrupt or corrupt sensitive U.S. military communications technology for collection. Bush, said China's military has targeted U.S.

Michelle Van Cleave, national counterintelligence executive under President George W. He was sentenced to four and a half years in prison. He pleaded guilty in 2008 to charges of disclosing national defense secrets to China. The affidavit said the talks involved disclosure of classified information.īergersen was director of command, control, communications, computers, and intelligence programs for the Navy.

The article discussed "broadband barrage jamming" and "partial-band interference" of JTIDS.Īs a result, the researchers "discovered that the only way to obtain a good interference result is to increase the interference power."Ī footnote to the article notes other work has been done on how to interfere with JTIDS communications.Īccording to court papers, Gregg Bergersen, a weapons system analyst with the Pentagon’s Defense Security Cooperation Agency, sold secrets on a JTIDS variant known as Po Sheng that was sold to Taiwan in the early 2000s.Īn FBI affidavit in the case revealed that Bergersen "discussed Po Sheng and communications security" during a dinner meeting on Mawith a Chinese agent identified as Tai Shenkuo. The Chinese article reveals that researchers have extensively studied JTIDS and produced several technical articles on the system. The article states that Chinese researchers have studied the JTIDS anti-jamming capabilities and formulated an "optimal jamming strategy from the point of view of the interferer." The article, "Anti-Jamming Performance of JTIDS-Type Waveform," was published July 10 in the journal Aerospace Electronic Warfare, a publication of Institute 8511, a unit of the China Aerospace Science and Industry Corporation (CASIC). The Chinese article reveals that the People’s Liberation Army is studying this feature and working to defeat it. It is also resistant to electronic warfare attacks by rapidly jumping to different frequencies. JTIDS allows for a nearly unlimited number of military commanders and operators to share information, such as precision location or position data, critical in tracking, monitoring, and targeting. military forces jam-resistant communications, a key strategic advantage used in joint warfighting, a specialty of the American military. JTIDS is part of a group of military communications systems called Link 16 that gives U.S. The disclosure that China has the capability of jamming the Joint Tactical Information Distribution System, or JTIDS, was revealed in a Chinese military technical article published in July. military secrets obtained from a convicted spy to defeat a high-technology communications system used in joint warfighting, combined arms warfare, and missile defenses, according to U.S.
