Press Release, London, 22 September 2026: Babcock International Group (Babcock), the defence company, has demonstrated its systems integration expertise by securely transferring scenario data using advanced encryption technology from Arqit Quantum Inc, a global leader in quantum-safe encryption, helping safeguard sensitive information from future cyber threats.
Data was collected at one site in Millbrook at DVD 2026, encrypted by Arqit software and securely transmitted to Babcock’s Ground Deployed Advanced Mortar System (GDAMS), located at another site at the event. It demonstrated how critical operational information could be exchanged securely in a layered encryption network between a headquarters and a deployed platform in a contested environment, enabling rapid and better-informed decision-making on the battlefield without the use of physical inline encrypters.
The demonstration follows the signing of a Memorandum of Understanding (MoU) between both parties to explore how Babcock’s capabilities in mission systems, systems integration, digital engineering and through-life support can be combined with Arqit’s expertise in cyber security, cryptographic technologies and secure networking. As a systems integration and secure communications expert, Babcock brings together best-in-class technologies to create secure end-to-end communications networks across a variety of Internet Protocol (IP) bearers, including 4G/5G, Wi-Fi and satcom, alongside legacy tactical and new MANET radios. The resulting network can be integrated across a wide range of crewed and uncrewed land, maritime and air platforms.
The demonstration also showcased the role of Babcock’s GDAMS within a digitally connected battlefield. Based on the proven ST Engineering mortar design, GDAMS combines mobile, network-enabled firepower with digital integration, enabling faster target engagement.
Louise Atkinson, Chief Executive, Babcock’s Land and Mission Systems business, said: “Armed forces need confidence their critical data can be transmitted quickly, reliably and securely, keeping sensitive information protected at all times.
“As technology evolves, so do cyber threats, and the emergence of quantum computing will challenge many of today’s encryption methods. We’ve demonstrated how we can integrate best-in-class technologies to create resilient and secure communications networks that help protect operational data against future quantum-enabled threats.”
Paul Feenan, Arqit General Manager for Government & Defence, added: “Modern operations require assured secure networks capable of working across multiple communication bearers. Arqit’s software-defined encryption, partnered with Babcock’s state of the art Advanced Layered System Architecture, can be deployed across networks from core to edge, enabling customers to keep intelligence and battlefield data secure against current and future threats.”
