Babcock International Group and Arqit demonstrated secure, quantum-safe data transmission at DVD 2026, with data collected at a Millbrook site encrypted by Arqit software and transmitted to Babcock’s Ground Deployed Advanced Mortar System (GDAMS) at a separate location without inline encryptors.

The data was encrypted by Arqit’s software before being securely sent to GDAMS during the event, showcasing end-to-end secure transmission between two sites.

The demonstration highlighted secure scenario data transfer between two sites using Arqit’s quantum-safe encryption technology.

Babcock’s system integrates multi-bearer networks—4G/5G, Wi-Fi, satellite, and tactical radios—to connect crewed and uncrewed land, sea, and air platforms.

Babcock positions itself as a systems integrator delivering end-to-end secure networks across various IP bearers for diverse platforms, including crewed and uncrewed units.

The approach enables seamless integration across 4G/5G, Wi‑Fi, satellite, and radio links to support mission networks across multiple domains.

Arqit’s Paul Feenan stressed that modern operations require secure networks capable of functioning across multiple communication bearers.

Feenan noted that software-defined encryption paired with Babcock’s architecture enables secure networks from core to edge bearers to protect intelligence and battlefield data against current and future threats.

GDAMS—based on the ST Engineering mortar design—highlights mobile firepower paired with digital integration for a digitally connected battlefield asset.

The demonstration showcased GDAMS as a digitally integrated platform designed to speed target engagement through seamless digital links.

Louise Atkinson, CEO of Babcock Land and Mission Systems, emphasized the need for fast, reliable, and secure data transmission in the face of evolving quantum threats.

The event followed a Memorandum of Understanding between Babcock and Arqit to explore collaboration in mission systems, systems integration, digital engineering, cyber security, and cryptographic technologies.
