Value proposition
Deliver accurate, low-cost, emission-free GNSS-denied navigation and sovereign autonomous sense-to-strike systems (surveillance towers, maritime effectors) built in Europe and validated in contested environments including Ukraine.
Products and solutions
Osiris: Low-cost, passive GNSS-denied navigation module for UAVs (optical + inertial); <15–20m CEP; proven 3,000+ km in Ukraine under jamming; ITAR-free COTS; primary company focus as of 2026., LAST (Delian Autonomous Surveillance Tower): Solar-powered AI surveillance/C-UAS towers for border monitoring, wildfire detection, and coastal defense; still deployed with Hellenic forces and exercised at Golden Sword-25., Interceptigon-N: Attritable maritime one-way effector USV for coastal A2/AD; ~18 nm range, >40 knots, flexible payload; live-fire testing planned with Hellenic Armed Forces., StrikeWeb / supporting stack: Proprietary C2 and sensor-fusion software connecting sensors to effectors (incl. EW and edge compute).
Unique value
The company employs a vertically integrated model, similar to Tesla and Apple, by developing its own hardware, AI-driven software, and sensor fusion systems in-house. This allows for rapid innovation and cost-effective production compared to traditional defense contractors.
Target customer
NATO, European Union member states, and other allied sovereign nations.
Industries served
Defense, National Security, Civil Protection
Technology advantage
Their key advantage lies in combining advanced AI and robotics with commercially available hardware from allied nations. This dual-use technology approach enables them to develop and deploy mission-critical systems quickly for both defense and civil applications (like wildfire detection) while ensuring sovereign capabilities for their customers.
How they differentiate
Delian Alliance Industries differentiates itself through vertical integration, developing its own hardware, software, and sensor fusion systems. This allows for the creation of low-cost, sovereign systems designed for mass deployment.
