The United States is concerned about China’s expanding ability to disrupt the most sensitive U.S. military and intelligence satellites, as Beijing pursues its expanded ambitions in space, according to multiple sources in the U.S. government and outside space experts.
A classified U.S. intelligence assessment completed late last year analyzed China’s increasing activities in space and mapped out the growing vulnerability of U.S. satellites that provide secure military communications, warn about enemy missile launches and provide precise targeting coordinates, said the sources, who were not authorized to speak publicly.
“It was a very credible and sobering assessment that is now provoking a lot of activities in different quarters,” said one former government official who is familiar with U.S. national security satellite programs.
The intelligence report raised red flags about Beijing’s ability to disrupt satellites in higher orbits, which could put the most sensitive U.S. spacecraft at risk, according to the sources. China has already conducted several anti-satellite tests at lower orbital levels in recent years.
Given the heightened concerns, Washington is keeping a watchful eye on Chinese activities that could be used to disrupt U.S. satellites. It is also urging Beijing to avoid a repeat of its January 2007 test that created an enormous amount of “space junk,” said one senior defense official.
Details of the latest Chinese moves that have raised U.S. concerns remain classified.
U.S. officials charge that China’s anti-satellite activities are part of a major military modernization that has seen Beijing test two new stealth fighters; step up cyber attacks on foreign computer networks; and launch more commercial and military satellites in 2012 than the United States.
China still lags behind the United States in most military fields.
“What we’re seeing is a heightened sense in the United States that China is a potential threat and that it has the technology to be a threat if it wishes to,” said Jonathan McDowell, with the Harvard-Smithsonian Center for Astrophysics.
