Europe’s True Hardware-Software
Defense Tech Company
Who We Are
Kalkan Defense Systems is a next-generation aerospace company based in Romania.
We design and build advanced military products for the modern battlefield — stealth-first, AI-ready, and sovereign by design.
What we do
We develop a fully integrated UAV ecosystem that combines cutting-edge aerospace engineering with AI-driven command and control.
Our product line — C1 Strigoi (combat UCAV), R1 Corvus (reconnaissance), and S1 Vultur (surveillance) — is unified through Kronos, our secure cloud platform for autonomy, coordination, and mission intelligence.
Our Mission
To deliver sovereign European defense technologies that protect nations, safeguard democratic values, and ensure operational superiority.
By uniting hardware and software innovation, we aim to build systems that are scalable, rapidly deployable, and future-ready for the evolving battlefield.
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 Defense Systems?
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.
