Cognitive Electronic Warfare. Spectrum Dominance.
Defence. Redefined.
Crown Defence provides cognitive electronic warfare systems that learn, adapt, and autonomously dominate the electromagnetic battlespace. We enable allied forces to think faster, see further, and respond at machine speed across strategic, operational, and tactical levels.
Cognitive systems are the only scalable solution for frequency-agile radars, software-defined threats, and adaptive adversaries. Our platforms employ machine learning to detect novel threats, develop optimal countermeasures, and adapt in real time. Microseconds, not minutes. Continuous learning, not pre-programmed libraries.
We deliver a modular, AI-powered airspace security platform that integrates real-time detection, signal intelligence, and autonomous threat response all in one seamless solution. Built to scale, integrate, and adapt, the system provides complete situational control without disrupting authorized operations.
Enhanced with hyperspectral imaging, our platform identifies threats based on unique spectral signatures unlocking a new dimension in aerial surveillance. Backed by ongoing research in smart electronic warfare, we are redefining the boundaries of modern, non-kinetic defence.
We work with both public and private sector clients operating in sensitive, security-driven environments. Onyks™ Platform is designed to adapt to diverse operational needs, from military-grade deployments to civilian security scenarios, without compromise
Crown Cyber Defence is a Finnish technology company shaping the future of defence systems.
Our expertise lies in the development of advanced electromagnetic technologies to meet today’s evolving security demands.
We collaborate with leading international research institutions and technology partners to design systems that are resilient, precise, and built for real-world use.
Machine learning systems that improve human judgment. Operators retain authority while receiving threat assessments and suggested actions at machine speed.
Designed for areas where allied forces operate: spectrum-dense combat zones, high-north operations, coalition task forces, forward operating bases, and strategic installations.
Tested under the harshest conditions. Proven through joint exercises. Prepared for deployment.
Protect friendly systems from hostile electronic warfare. Precise electromagnetic effects that disable threats while maintaining allied communications, navigation, and sensors.
Force Protection and Resilience
Multi-Domain Integration
Electromagnetic Spectrum Superiority
Open architecture enables seamless integration with allied C4ISR, joint fires networks, and coalition force structures. Mission-configurable across air, land, and maritime domains.
Crown Defence systems deliver full-spectrum electronic warfare across attack, protection, and support functions. We provide:
AUTONOMOUS DECISION SUPPORT
Cognitive pattern recognition and real-time threat analysis. Detect new emitters, anticipate adversary actions, and develop capabilities through software, rather than hardware replacement.
Control the Spectrum. Control the Battlefield.
LIMITATIONS OF LEGACY SYSTEMS
Why Traditional Counter-Drone and Electronic Warfare (EW) Tools Fall Short
We see how future of the theater needs smarter tools to counter large fleets of UAVs, UGVs and other human-operated or autonomous systems. Most importantly we believe there is a solid, non-kinetic path and secure way in doing this without disrupting operational control or causing collateral interference.
Until now, counter-UAS systems have compromised their own communications, created operational blind spots, and required manual intervention at every step.
There has been no smart, scalable, and unified solution one that protects your assets, filters only threats, and reacts instantly. Now, there is.

ONYKS™ platform
ONYKS™ is Crown Defence's modular cognitive EW platform covering the entire range of electromagnetic warfare operations.
Multi-spectral sensor fusion enables real-time threat detection and classification. Machine learning models generate optimal countermeasures dynamically, from jamming parameters to deception techniques. Precision targeting neutralises hostile systems while safeguarding friendly operations. Open standards facilitate coalition integration.
Scalable from individual operators to theatre-level systems. Deploy as man-portable units for tactical forces. Integrate into vehicle and platform systems for operational units. Orchestrate across networks as a system-of-systems for strategic command. A common cognitive engine across all levels ensures consistent capability and seamless interoperability.
ONYKS™ continuously learns from operational environments. Each deployment enhances performance. Each engagement broadens capability.
Applications include: Counter-UAS operations. Radar suppression. Communications jamming. SIGINT collection. Force protection. Offensive electromagnetic manoeuvre.
The Unified Approach to Modern Drone Defence
ONYKS™ BY CROWN DEFENCE
In an era where airspace is increasingly contested, maintaining operational control is not optional, it's mission-critical.
ONYKS™ ensures uninterrupted operations through intelligent UAV classification and real-time threat response, all without disrupting authorized systems.
The system reacts autonomously in seconds, escalating responses only when needed. Powered by advanced signal defence, AI decision logic, and hyperspectral imaging, ONYKS™ introduces a new paradigm in non-kinetic defence.
