Pioneering the Future of Aerospace and Defense
Who we are
Kalkan Defense Systems is a next-generation aerospace company based in Romania.
We design and build advanced military UAVs for the modern battlefield — stealth-first, AI-ready, and sovereign by design.
Why It Matters
🇪🇺 European-built, NATO-aligned
No dependency on U.S. or non-NATO tech.
🧠 AI-native by design
Advanced autonomous mission systems & swarm coordination.
📍 Strategic location
Based in Romania, at the NATO frontier with direct access to EU defense programs and industrial base.
Our product line
R1 Corvus
A stealthy tactical recon UAV built for frontline intelligence.
With 10–12 hr endurance, modular EO/IR, LiDAR and SIGINT pods, and GPS-denied navigation, Corvus delivers real-time situational awareness where you need it most—quietly, reliably, and on demand.
C1 STRIGOI
JET Powered Combat UAV
Our jet-powered combat UCAV pushes Mach 0.95, carries up to 1 800 kg in its internal weapons bay, and leverages L3 autonomy for precision strike missions.
Low-RCS shaping, AESA radar integration and encrypted mesh comms make Strigoi the stealthy punch-out platform for contested airspace.
S1 Vultur
A MALE-class surveillance workhorse with a 20 m wingspan and 30 hr loiter capability at 12 500 m.
Vultur’s multi-sensor payloads (SAR, EO/IR, SIGINT) and high-bandwidth SATCOM relay keep your command center seamlessly connected—even across the horizon.
Why Kalkan?
100 % European Sovereignty
We design, build, and support every system right here in Romania—no ITAR choke-points, no outside dependence.
Battle-Proven Innovation
From stealth shaping to AI-native autonomy, our drones pack real combat tech, not PowerPoint concepts.
Modular & Scalable
Swap payloads in minutes. Scale from a single Strigoi UCAV to swarms of Corvus recon birds and Vultur ISR workhorses.
NATO-Ready, Export-Friendly
Fully STANAG-compliant, with secure mesh comms and export pathways already cleared for allied partners.
Rapid R&D to Flight
Lean startup pace meets aerospace rigor: our digital-twin engine slashes prototype time by 40 %, getting drones in the air faster.
