Babcock International Group and Arqit Quantum Inc recently demonstrated a secure data transfer at DVD 2026, originating at Millbrook and reaching Babcock’s Ground Deployed Advanced Mortar System (GDAMS) at another event site, the company says. The successful transmission utilized Arqit’s encryption software, showcasing a shift away from physical hardware towards software-defined security for battlefield communications. This network integrates 4G/5G, Wi-Fi, satcom, legacy tactical radios, and new MANET systems, enabling secure exchange across diverse communication types.
“Armed forces need confidence their critical data can be transmitted quickly, reliably and securely,” said Louise Atkinson, Chief Executive of Babcock’s Land and Mission Systems business. 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 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.”
Arqit Software Secures Data Transfer at DVD 2026
This successful transfer utilized Arqit’s encryption software without relying on physical inline encryptors, a departure from traditional battlefield communication security methods. The demonstration highlighted a shift towards software-defined encryption capable of operating across diverse communication channels. The integrated network extended beyond dedicated military frequencies, incorporating 4G/5G, Wi-Fi, and satellite communications alongside legacy tactical and modern MANET radio systems.
This broad compatibility suggests a move towards integrating commercial and military infrastructure for enhanced security, allowing data to flow seamlessly between different networks. Arqit, founded in 2017 and now publicly listed as ARQQ on Nasdaq, develops and licenses quantum key distribution (QKD) technology for symmetric encryption, serving both government and commercial clients.
The company’s Encryption Intelligence product, launched fully in January 2026, provides automated cryptographic discovery for post-quantum migration and compliance, identifying vulnerabilities and mapping dependencies, according to the company. As the threat of quantum computing looms, current encryption methods could become obsolete. “As technology evolves, so do cyber threats, and the emergence of quantum computing will challenge many of today’s encryption methods,” Babcock said. Arqit’s recent partnerships with RAD, Northrop Grumman, and nLighten further demonstrate its commitment to providing comprehensive quantum-safe solutions across various sectors.
Babcock’s GDAMS, based on an ST Engineering mortar design, further enhances this capability by combining mobile firepower with digital integration, enabling faster target engagement within the secured network.

The integrated system addresses the escalating threat posed by advancements in quantum computing, which could render many current encryption methods obsolete. This approach, according to Arqit, ensures both data protection and compliance with evolving security standards. Babcock, a FTSE 100 international defence company, combines this technology with its expertise in systems integration and through-life support, creating resilient communication networks.
