Communications defence companies in Germany

Designs and integrates SIGINT, COMINT and electronic warfare systems for intelligence, law enforcement and defence customers across land, naval and airborne platforms.

ICAS (Intelligence Control and Analysis System)

Manufacturer-independent software platform that covers the entire radio reconnaissance cycle: sensor control and integration, signal interception, analysis, geolocation and export to higher-level command systems. ICAS is interoperable across different sensor manufacturers and scalable from single tactical deployments to large strategic installations. It includes AI-assisted voice activity detection and speech-to-text capabilities for processing intercepted radio communications. Deployed in land, naval and stationary configurations worldwide.

Designs and integrates open-architecture naval communications systems, secure military messaging and submarine antenna solutions for navies worldwide.

APCOS 4000 – Integrated Communication System

Open-architecture digital communications platform for surface warships and submarines. APCOS 4000 handles tactical voice, internal comms, radio system integration, IP routing, voice over IP and strict separation of classified and unclassified traffic. Network nodes interconnect via a redundant dual fibre-optic ring, ensuring survivability in the event of cable breaks or node faults. Deployed on the German Navy's F125 frigate programme among other vessels.
