Design, development and production
under one roof.
REB Defence is a Slovak engineering company specialising in electronic warfare and counter-unmanned aerial systems. Our radar front end, radio-frequency hardware, effectors and signal-processing software are developed by our own engineers and produced in Slovakia. We hold the design authority for every core component we supply, which is what allows us to modify it on an operational timescale rather than a procurement one.
Reaction time measured in weeks.
Large contractors carry long approval chains and fixed supplier agreements. We carry neither. Requirements reach the engineers who will implement them without passing through a boardroom first, and the products are shaped by the conditions they are used in rather than by a roadmap written two years earlier.
We are not a systems integrator patching together off-the-shelf, third-party components. From signal-processing algorithms to bespoke RF spectrum analysers and rapidly deployable effectors, end-to-end control over the development process is what guarantees our adaptability.
When a new adversary tactic, a frequency-hopping drone or a new electronic threat emerges, our reaction time is measured in days and weeks. Not years.
In the modern battlespace, the only constant is adaptation.
Aerial threats and the radio-frequency landscape change by the day. Legacy defence cycles are no longer fast enough. We were built specifically to outpace that.
Hardware
Radar front end, RF spectrum analysers, effectors, acoustic nodes and the vehicle integration — designed and built by us.
Software
Signal processing, classification, fusion, track management and the operator console. No third-party black box in the critical path.
Services
Site survey, system architecture, installation, integration with customer sensors and communications, and sustainment.
Training
Operator and maintainer training on the delivered configuration, on the customer's own ground and threat picture.

REB Defence systems may be subject to Slovak and European Union export-control law, including Regulation (EU) 2021/821 on dual-use items. Radio-frequency effect systems are supplied to authorised government, defence and law-enforcement end users only, and their employment remains subject to national spectrum authority, rules of engagement and applicable law.
What we build.
C2 Defender
Mobile command post and multi-domain fusion node. Radar, RF, electro-optics, acoustics and UAV feeds converge into one picture.
ADP
Handheld counter-UAS jammer, 400–6000 MHz, extendable to 12 GHz. Directional and spatial effect from one system.
AcuSync
Hears UAS and small-arms fire on eight microphones, names the threat and points at it — without transmitting a detection signal of its own.
C2 Minions
Four rugged pan-tilt-zoom cameras in transport cases. Live feed straight to C2 Defender, no operator at the position.
I2 Defender
Compact unmanned aircraft launched on a sensor cue. Closes the distance, identifies what it finds and stays with it using Lock2Trace.
C4TAK
Puts the fusion picture on the team's devices. Positions, tasks, hazards and sensor alerts, disseminated by role.

Give us the area of operations, the threat picture, the units taking part and the authority you hold. We will come back with a system architecture and a realistic timeline — not a catalogue.
