A Chinese spy balloon, which transited the US earlier this year, was able to capture images and collect signals intelligence from several US military sites. According to a source familiar with the matter, the balloon was able to transmit information back to Beijing in real-time. However, it is unclear whether the Chinese government could wipe the balloon's data as it received it.
The incident has raised concerns about the effectiveness of US intelligence gathering methods, particularly when it comes to detecting and tracking Chinese surveillance balloons. The US intelligence community believes that the balloon was not a significant collection hazard beyond what already exists in "actionable technical means" from China.
In February, a senior State Department official stated that the balloon was capable of conducting signals intelligence collection operations while it floated across the US. However, Gen. Glen VanHerck, the commander of US Northern Command and NORAD, said at the time that the US did not assess that the balloon presented a significant collection hazard.
The surveillance program, which includes several similar balloons, is run out of the small Chinese province of Hainan. The US does not know the precise size of the fleet of Chinese surveillance balloons, but sources indicate that the program has conducted at least two dozen missions over at least five continents in recent years.
Roughly half a dozen of those flights have been within US airspace, although not necessarily over US territory, according to one official familiar with the intelligence. China has maintained that the balloon was actually just a weather balloon thrown off course, and the US has been assessing the possibility that it was not deliberately maneuvered into the continental US by the Chinese government.
Despite this, officials believe that China did maintain some ability to maneuver the balloon once it was over Montana. And once the balloon was in position, China appeared to take advantage of its location to loiter over sensitive sites and try to collect intelligence.
