The balloon entered US airspace via Alaska, floated over sensitive military sites, and eventually reached the East Coast
A Chinese spy balloon that drifted across the United States before being shot down off the South Carolina coast in February 2023 was found to contain technology from at least five American companies, according to a recent report.
The findings, first reported by Newsweek, come from a US military analysis of the balloon’s wreckage. The examination revealed that the aircraft was equipped with a satellite communication module, sensors, and advanced surveillance equipment—some of which was stored inside a foam cooler. Despite these revelations, the FBI has not yet made an official statement on the matter.
The balloon entered US airspace via Alaska, floated over sensitive military sites, and eventually reached the East Coast before being shot down over the Atlantic on 4 February 2023. While Beijing initially claimed it was a civilian weather balloon, US intelligence agencies later confirmed that it had been used for espionage purposes. However, reports suggest that while the balloon gathered intelligence, the data never reached China.
Among the American-made components discovered in the balloon was an Iridium 9602 short-burst messaging module, manufactured by Virginia-based Iridium. Addressing the issue, the company’s communications director, Jordan Hassim, told Newsweek that Iridium does not support the misuse of its technology. He explained that their modules are typically used for applications such as wildlife tracking and aiding explorers.
Other US companies whose technology was identified in the balloon include Texas Instruments, Omega Engineering, Amphenol All Sensors Corp, and Onsemi. Additionally, Swiss-based STMicroelectronics was found to have components in the device.
The incident has raised concerns about how US-made technology ended up in a surveillance balloon operated by China. It also highlights the ongoing challenge of preventing advanced technology from being repurposed for military or intelligence activities by foreign entities.
