HENSOLDT develops sovereign defence sensor cloud

Modern armed forces increasingly rely on distributed sensors and cloud processing to coordinate land, air, sea and cyber operations. In this context, HENSOLDT and Schwarz Digits established a partnership to develop integrated, cloud-enabled and data-driven defence systems.

Classified data handling in sovereign infrastructure
The cooperation targets military environments where operational data must remain under national control. Schwarz Digits provides the STACKIT cloud platform as the computing infrastructure, designed to process information up to the German VS-Secret classification level.

Secure communication stacks enable exchange of classified data, while quantum-resistant encryption and cybersecurity mechanisms protect data streams against interception and manipulation. The approach focuses on building a sovereign data environment rather than relying on external hyperscale cloud providers, a requirement increasingly associated with digital sovereignty in defence procurement.

Sensor fusion across operational domains
HENSOLDT contributes the MDOcore (Multi-Domain Operations Core) software suite, a modular platform that aggregates heterogeneous sensor inputs and performs AI-supported data fusion. The software acts as an integration layer between distributed sources such as radar, optronics, electromagnetic signal intelligence and active or passive sensors.

The combined system connects sensor data from multiple operational domains and correlates it in a shared operational picture. Supporting elements include interoperability services, distributed data management and mission-system integration across land, air, sea, cyber and space environments.

Simulation and synthetic environments are also part of the contribution, providing datasets for training artificial intelligence models, validating software behaviour and testing operational workflows before deployment.

From infrastructure to operational capability
The partnership plans prototype systems in 2026, combining the STACKIT infrastructure with HENSOLDT sensor technology and integration software. One demonstrator integrates cloud services directly into a sensor solution, allowing data processing beyond the platform edge while maintaining classified handling requirements.

Operational context
The architecture links sensing hardware, communication networks and cloud analytics into a single operational framework. By combining sensor fusion software with sovereign cloud infrastructure, the partners aim to support networked operations where decisions depend on rapid correlation of distributed battlefield data across domains.
