Crown Defence is a Finnish defence technology company developing cognitive electronic warfare systems for NATO member states and allied forces. Defence. Redefined.

The ONYKS™ platform provides systems that learn, adapt and maintain spectrum superiority across the electromagnetic battlespace. Allied forces can think faster, see further, and respond at machine speed across the strategic, operational, and tactical levels.
Modern electronic warfare is more about learning than hardware. Adversaries continuously change frequencies, alter flight profiles, and adapt tactics. A system based on known threats is already outdated upon deployment. What is needed is a platform that learns, not just a library that gets updated.

ONYKS™ encompasses the entire EW spectrum within a single architecture: Electronic Support, Electronic Attack, and Electronic Protection. The Neural Engine processes RF, acoustic, and hyperspectral data simultaneously, generates threat assessments with confidence levels, and suggests courses of action. The operator approves. The system then executes. Decision speed improves; command authority remains with the operator.

ONYKS™ targets only hostile signals. Coalition partner communications persist. Navigation functions are active. Friendly sensors stay operational, which is essential for deployment in any joint operational environment.
Finnish origin within EU and NATO frameworks ensures full capability transfer, an independent supply chain, and technology controlled by the customer, not licenses.
