AUKUS to Deploy Undersea Drones to Protect Critical Submarine Cables and Pipelines

The AUKUS security alliance—comprising the United States, the United Kingdom, and Australia—has announced plans to jointly develop and deploy a new generation of unmanned underwater vehicles (UUVs) to safeguard critical undersea infrastructure, including submarine communication cables and energy pipelines.

The initiative was unveiled during a meeting of the three countries' defense ministers on the sidelines of the Shangri-La Dialogue in Singapore. Officials said the autonomous underwater drones are expected to begin deployment next year.

According to reports from CNN, Western nations are increasingly concerned about the vulnerability of submarine cables and pipelines to potential sabotage by Russia and China. There are also growing fears that Iran could exploit or disrupt data networks running through the shallow waters of the Persian Gulf to advance its strategic interests.

Currently, there are approximately 570 active submarine cables worldwide, with around 80 more under development. These fiber-optic networks carry between 95% and 99% of global telecommunications and internet traffic. Compared with satellites, submarine cables offer significantly greater data transmission capacity. In addition, undersea power cables used for transmitting renewable energy are becoming increasingly important.

The importance of these networks has grown further with the rapid expansion of artificial intelligence (AI) infrastructure and data centers. Major data center projects in Saudi Arabia and the United Arab Emirates rely heavily on submarine fiber-optic cables to ensure secure digital connectivity and service delivery.

The Strait of Hormuz alone hosts several major submarine cable routes that carry substantial volumes of global e-commerce, cloud computing, banking, and communications data. Since the outbreak of tensions in the Middle East, Iranian state-affiliated media outlets have repeatedly highlighted the vulnerability of these cable corridors.

Recently, Iran's semi-official Tasnim News Agency published a map of the cables crossing the Strait of Hormuz, describing them as highly vulnerable. Another semi-official Iranian media outlet also argued on Saturday that all fiber-optic cables passing through the strait should be subject to Iranian tolls.

Similarly, the Red Sea serves as a vital route for data traffic between Europe, Asia, and Africa. Any disruption to shipping lanes or submarine cable infrastructure in either the Strait of Hormuz or the Red Sea could trigger significant economic consequences worldwide.

In response to these growing threats, AUKUS members have stepped up efforts to strengthen the protection of critical undersea infrastructure.

Speaking at the conference, Australian Defence Minister Richard Marles described the seabed as a new "battlefield." He called undersea internet cables "the arteries of modern civilization" and warned that incidents involving damaged or severed cables are becoming increasingly common. He noted that island nations such as Australia remain particularly vulnerable to such disruptions and highlighted a series of attacks on critical undersea infrastructure over the past 18 months.

UK Defence Secretary John Healey issued a warning to Russian President Vladimir Putin, stating: "We see what you are doing. We know what you are doing, and we will not tolerate attacks on our cables and pipelines. The consequences will be severe."

Last month, the United Kingdom reportedly tracked three Russian submarines conducting covert surveillance activities near undersea cables in the North Atlantic.

According to AUKUS officials, the new unmanned underwater vehicles will be equipped with advanced sensors and weapons systems. The drones are expected to significantly enhance the three nations' capabilities in maritime surveillance, anti-submarine warfare, and mine countermeasure operations.

US Defense Secretary Pete Hegseth said the autonomous underwater platforms would be highly adaptable and capable of supporting a wide range of military and security missions on the ocean floor.

The announcement reflects increasing concern among Western allies that the protection of undersea infrastructure is becoming a critical element of both national security and global economic stability.
