UK naval drones sent data to China, raising US, European fears over Chinese components -report

The United Kingdom's Ministry of Defense has disconnected its £12 million fleet of K3 Scout surveillance drones from the internet after discovering that camera components transmitted data to an internet address in China. The discovery was made during a routine cyber-vulnerability assessment, which identified "heartbeat communications" – data confirming devices are online and functioning, with the potential to share location.

no evidence was found that any Defense Ministry data or systems were accessed, compromised, or transmitted.

While the Ministry of Defense stated that no defense data or systems were accessed or compromised, the incident has amplified fears shared by the US and European countries regarding the use of Chinese-made components in critical military hardware. The drones' supplier, Kraken Technology Group, had reportedly received security assurances from its third-party camera vendor. A Kraken spokesperson expressed confidence that no sensitive information was shared and that all vulnerabilities have been addressed.

This reliance on Chinese components, including brushless motors, antennas, cameras, and batteries, is largely driven by their significantly lower cost compared to alternatives. For countries like Ukraine, which uses thousands of drones monthly, affordability is a major factor. However, manufacturers like Germany's Arx Robotics are establishing supply chains within Europe and the US to enhance robustness and durability, despite the higher price.

A German electric engine is five to 10 times more expensive than a Chinese one.

Despite US bans on Chinese drone components, the pervasive nature of small parts means they can still infiltrate supply chains. This incident highlights the ongoing challenge of balancing cost-effectiveness with national security concerns in the defense sector.

We pay the price, but we get robustness and durability in return.
