U.K. Naval Drones Found Transmitting Data to China Through Camera Components

Aug 10, 2026

The UK Ministry of Defence has launched an investigation after cameras on the Royal Navy's £12.3 million fleet of K3 Scout drones were found transmitting "heartbeat communications" to an IP address in China. Discovered during a routine cyber assessment, the transmissions only confirmed the cameras' online status, and officials state no sensitive military data was compromised. The incident has intensified scrutiny over defence supply chain vulnerabilities as the Royal Navy expands its autonomous "Hybrid Navy" capabilities.

K3 Scout camera China transmissions

▪The Royal Navy purchased 20 K3 Scout drones for £12.3 million under its Project Beehive surveillance and force protection programme.
▪Cameras on the Royal Navy's K3 Scout surveillance drones were discovered transmitting data to an internet address in China.
▪The K3 Scout drones are manufactured by British firm Kraken Technology Group, using cameras supplied by an assured third-party vendor.

Defence supply chain vulnerabilities

▪Security experts warn that modern military platforms are vulnerable to security risks through minor hardware and software components embedded in supply chains.
▪The discovery of drone cameras transmitting data to China has highlighted the vulnerability of military supply chains to Chinese-sourced components.

MoD investigation findings

▪Kraken Technology Group stated that audits conducted with the Royal Navy identified and closed the potential vulnerabilities in the K3 Scout programme.
▪Following the discovery, the Ministry of Defence disabled internet connectivity for the affected camera equipment and launched a system review.
▪The UK Ministry of Defence identified the K3 Scout drone camera transmissions during a routine cyber vulnerability assessment.
▪A Ministry of Defence investigation found no evidence that any operational, classified, or Ministry of Defence data was compromised.

Royal Navy autonomous systems

▪The Royal Navy's Coastal Forces Squadron and 47 Commando Royal Marines use the K3 Scout vessels for surveillance, training, and operational activities.
▪The Royal Navy is investing in autonomous military technology as part of its "Hybrid Navy" strategy to integrate drones and uncrewed vessels.

Heartbeat communications to Chinese servers

▪The transmissions from the K3 Scout drone cameras consisted of "heartbeat communications" sent to an IP address in China.
▪The heartbeat communications from the drone cameras only confirmed the online status and normal functioning of the camera subsystems.
