The AUKUS security partnership between the U.S., Australia, and the U.K. is developing advanced unmanned undersea vehicles to protect critical global telecommunications cables from potential foreign sabotage.

Key Points

• Approximately 650 existing and planned undersea cables carry up to 99% of global intercontinental telecommunications data.
• The AUKUS initiative aims to deploy cutting-edge sensors and weapons systems on underwater drones to enhance reconnaissance and anti-submarine capabilities.
• Western officials cite an unprecedented increase in attacks on subsea infrastructure, specifically noting concerns regarding Russian, Chinese, and Iranian activities.
• The U.K. recently tracked Russian submarines surveying cable routes in the North Atlantic, highlighting the vulnerability of digital and financial data highways.
• Australia’s Defence Minister Richard Marles described the seabed as a new battlefield, emphasizing the need for increased protection of these essential infrastructure arteries.

Why it Matters

• These undersea cables serve as the backbone of the global economy, facilitating nearly all international financial transactions and cross-border trade. Securing this infrastructure is vital to preventing systemic economic disruption and maintaining national security in an era of increasing geopolitical tension.
