Naval & Maritime defence companies in Germany

Builds cloud and on-premises big data platforms for managing, processing and visualising underwater and terrestrial sensor data, serving navies, offshore wind operators and hydrographic agencies.

Designs and manufactures submarine sonar suites, anti-submarine warfare systems and seabed surveillance technology for navies worldwide, with nearly 100 years of hydroacoustic expertise from Kiel, Germany.

Sphere® Passive Surveillance (KaleidoScope 2.0)

An open sonar suite designed for conventional submarines, providing full spatial, spectral and temporal acoustic coverage. It combines narrowband and broadband passive sonar for contact detection, tracking and classification, with acoustic intercept and analysis tools. The system is built on MOTS hardware with fully in-house designed and manufactured hydrophone arrays, and its modular architecture supports upgrades and future capability growth with reduced lifecycle costs. ELAC SONAR's Sphere®-based KaleidoScope 2.0 is the sonar suite selected for Italy's U212 NFS submarine programme.

Builds hoistable mast systems, submarine components and torpedo-tube-launched unmanned surface vessels for naval forces 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.

Designs, manufactures and commissions HF radio communication systems and antenna infrastructure for military and government customers. One of Europe's leading integrators for naval ship-to-shore HF comms covering VLF through UHF bands.

Manufactures rugged MF/HF military and submarine antennas under the DUK brand. Installed on naval fleets worldwide including the German Navy. Founded 1952, all products made in Germany near Hamburg.

Builds the Greyshark family of autonomous underwater vehicles for long-range ISR and subsea infrastructure protection. The hydrogen-powered Foxtrot variant can operate for 16 weeks covering 11,000 nautical miles. Partnered with Rheinmetall for coastal defence integration.

GREYSHARK Autonomous Underwater Vehicle

Long-endurance autonomous underwater vehicle developed with EvoLogics for mine countermeasures, subsea infrastructure monitoring, ISR, coastline defence and patrol missions.

Power Electronics

Rugged pulse power, launcher power supply and naval UPS systems designed for weapon systems, navigation, communications, control and other mission-critical defence platforms.

Day and Night-View Systems

High-precision opto-electronic systems combining electro-optical sensors, thermal imaging and AI-assisted image processing for ground vehicles and naval platforms.

Counter-Drone Technology

AI-driven counter-drone capabilities focused on detection, classification and mission-system integration for defence and critical-infrastructure protection.

Designs biomimetic underwater robots and acoustic communication systems for naval and offshore operations. Products include autonomous underwater vehicles inspired by penguin locomotion and dolphin-based acoustic modems for subsea positioning. Founded in 2000 in Berlin.

Designs and manufactures autonomous uncrewed surface vessels for naval defence including the Q-RECON series and underwater vehicles. Combines AI-powered Q-MIND autonomy software with maritime hardware for coastal surveillance and special forces operations.

Builds military inflatable boats and rigid-hull inflatables for special forces, rescue services and naval operations. Based near Hamburg, the company has designed customized boats for government agencies and security forces since 1987.
