Tenna raises $13.5 million to chart invisible battlefields
Defense technology startup Tenna has secured a fresh $13.5 million funding round to expand its work mapping electromagnetic threats for the US military and allied forces. The capital will support the company’s efforts to turn the invisible spectrum of radio waves, radar emissions and electronic interference into actionable intelligence for commanders.
Turning the electromagnetic spectrum into a tactical map
Tenna develops hardware and software that detect, classify and visualize signals across the electromagnetic spectrum. By fusing sensor data, AI algorithms and advanced signal processing, the platform aims to show where hostile emitters are located, how they are behaving and how they might disrupt friendly operations.
Modern militaries increasingly depend on satellite communications, GPS navigation, radar and secure wireless networks. That reliance creates new vulnerabilities: jamming, spoofing and targeted electronic attacks can blind sensors, cut communications and mislead precision weapons. Tenna positions its technology as a way to give forces an up-to-date, map-like picture of these risks in real time.
Supporting US and allied electronic warfare strategies
The new funding underscores growing demand in Washington and among partner nations for tools that improve electronic warfare readiness. Defense planners view control of the spectrum as a core requirement for any future conflict, alongside air, land, sea, space and cyber domains.
According to the company, Tenna is working with both US defense agencies and allied militaries to integrate its mapping capabilities into existing command-and-control systems. The goal is to let commanders see electromagnetic hazards alongside conventional threats such as missile launches, drone activity or troop movements.
Scaling technology and deployments
The $13.5 million injection will be used to refine Tenna’s analytics platform, harden its systems for deployment in contested environments and expand its field testing programs. The company also plans to grow its engineering and data science teams to accelerate product development.
As defense budgets increasingly prioritize situational awareness and multi-domain operations, startups like Tenna are vying to become critical suppliers of spectrum intelligence. The latest round gives the company additional runway to prove that detailed electromagnetic maps can become as indispensable as traditional battlefield charts for US and allied forces.
