Here’s Why China May Be Using Old-Fashioned Surveillance Technology When Satellites Exist
How unusual are spy balloons these days?
-----------------------------
This isn’t the first time in recent history that a balloon from China has been spotted by foreign security officials.
After the sighting this week, the U.S. Dept of Defense said in a statement: “Instances of this kind of balloon activity have been observed previously over the past several years.”
Last Feb, authorities in Taiwan said they discovered weather balloons deployed by the Chinese People’s Liberation Army floating above the self-governing island that China claims as its territory. While some speculated the balloons could be used for
surveillance, officials in Taipei accepted that they were meant for meteorological observations only.
China has been developing new balloon surveillance technology for years, but it’s not the only country to do so.
Last May, Politico reported that the Pentagon spent around $3.8 million on balloon projects over the past two years and planned to spend more than $27 million on the inflatable tech in fiscal year 2023. The balloons, according to the report, will collect
data and transmit info to aircraft and may eventually be used to scan for hypersonic weapons developed by China and Russia.
Why use balloons when satellites exist?
-----------------------------------
China has an extensive satellite network. In a Nov. 2022 report, the Defense Dept said China’s intel, surveillance, and reconnaissance-capable (ISR) satellite fleet had more than 260 systems, second only to the U.S., as of the end of 2021. A senior
defense official noted on Thursday that, for China, the balloon flying over Montana “has limited additive value from an intelligence collection perspective.”
Yet even with satellite tech surpassing some abilities of balloons, James Char, a research fellow with the China Program at the S. Rajaratnam School of Int'l Studies in Singapore, tells TIME that spy balloons have some operational advantages. For example,
balloons can weather extreme conditions, he says, and are less expensive to deploy and operate compared to satellites. Chinese Academy of Science scholars found in 2020 that, despite harsh environments at more than 68,000 feet above ground, “the high-
altitude balloon has long endurance time, which can achieve sustained and wider coverage for regional observation and detection.”
“It is harder to be spotted by radar as well, given the fact that they’re simpler in terms of technology,” Char adds. U.S. officials admitted the balloon flying over North America this week was first spotted by civilians on a plane.
High-altitude balloons can also be “trucks for any number of platforms, whether it be communication and data link nodes, ISR, tracking air and missile threats — and without the predictable orbits of satellites,” Tom Karako, senior fellow for the
International Security Program and director of the Missile Defense Project at the Center for Strategic and Int'l Studies, told Politico.
And though the technology is old, says Bec Shrimpton, director at the Australian Strategic Policy Inst., balloons can complement surveillance tech in orbit, while they can be built and deployed at a fraction of the cost. According to a 2020 analysis in
defense publication Armada Int'l, the development, launch, operation, and insurance of a single satellite can cost up to $300 million.
Another potential edge for balloons, Shrimpton tells TIME, is how unlikely defense officials may have been prepared for it to be used, especially by China. “It’s probably better because it’s unexpected,” she says. “It’s not that we haven’t
seen this before, but we are expecting far more from Chinese surveillance efforts.”
If it’s caught, what’s the point?
------------------------------
“It is bold, in that it was always likely to be detected, it was always likely to be seen,” says Shrimpton. That’s what military experts like her find most notable about the balloon, especially given the timing of its emergence—just after the U.S.
reinvigorated its military alliance with the Philippines and before Secretary of State Antony Blinken’s scheduled trip to Beijing, which has now been postponed.
“I think it’s another demonstration of the Chinese military’s adherence to operations below the threshold of war, that’s number one,” says Char. “Clearly for reasons that are known to everyone,” he adds, “the U.S. and the Chinese don’t
want to escalate matters above.”
“It is a threat, no doubt,” Char says. “But how serious is it? I think it’s pretty clear: if it’s serious enough, I’m sure something more drastic would have been done by the U.S. establishment.”
