Babcock International and Arqit Quantum have demonstrated a secure end-to-end data transfer capability during DVD 2026, leveraging quantum-safe encryption to safeguard critical operational data across contested battlefield environments. During the demonstration at Millbrook, scenario data collected at one site was encrypted via Arqit software and transmitted wirelessly to Babcock’s Ground Deployed Advanced Mortar System (GDAMS) at a separate location on the event grounds. The trial showcased a layered encryption network capable of exchanging real-time tactical intelligence between a headquarters element and a deployed weapon system without relying on traditional physical inline encryptors, thereby accelerating command-and-control decision cycles in high-threat electronic warfare settings.
The tactical demonstration follows a Memorandum of Understanding (MoU) signed between the two defense vendors to combine Babcock’s expertise in mission systems, digital engineering, systems integration, and through-life support with Arqit’s advanced cryptographic and secure networking software. By integrating software-defined quantum-safe encryption across multi-domain networks, the partnership aims to harden tactical communications against emerging cyber threats and future quantum-decryption vectors. The architecture is engineered to establish secure IP bearers across diverse tactical radio networks, including legacy combat net radios, modern Mobile Ad-hoc Networks (MANET), 4G/5G cellular nodes, Wi-Fi, and satellite communications (SATCOM) links across crewed and uncrewed land, maritime, and aerial platforms.
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.”
In addition to validating secure data transport, the event highlighted the role of Babcock’s GDAMS as a digital node within a multi-domain connected battlefield. Derived from ST Engineering’s combat-proven automated mortar architecture, the platform pairs mobile, network-enabled indirect fire capabilities with digital fire control integration to achieve rapid sensor-to-shooter engagement times. By embedding Arqit’s encryption software into the GDAMS network architecture, the exercise demonstrated how digitized artillery platforms can securely receive and execute targeting data in highly contested electromagnetic environments without compromising data integrity or operational tempo.
