We design, prototype and test unmanned aircraft systems. Our partner companies in Ukraine put each iteration through real operating conditions, so what we learn goes straight back into the next design.
We work on the whole aircraft system, from the airframe to the software that flies it. Projects run as contract R&D for a client or as joint development with a partner.
Multirotor and fixed-wing platforms designed around the job: payload, endurance, and how easily a crew can repair them away from a workshop.
Flight software that keeps an aircraft useful when conditions are poor, including when satellite positioning or the radio link is unreliable.
Counter-drone aircraft for protecting sites and people against hostile unmanned aircraft, developed alongside detection-system partners.
Every project moves through the same five stages. You get a written review at the end of each one before the next begins.
We agree what the system has to do, in what conditions, and how success will be measured.
Concept, simulation and component selection, reviewed with you before anything is built.
We build flying prototypes and bench-test every subsystem.
Partners test the prototype in real operating conditions and report back in detail.
You receive the design files, test data and a plan for moving into production.
No country has more recent, practical experience of building and operating drones at scale. We maintain working relationships with Ukrainian manufacturers, engineering firms and test teams, and that experience shapes what we design.
Partners report what worked and what failed while the prototype is still on the bench, which shortens each design cycle.
Designs are judged against weather, radio interference and rough handling, which a lab can't reproduce.
We co-develop components and software with Ukrainian teams and bring their proven ideas to wider markets.
We take on work from manufacturers, integrators, government bodies and research institutions.
Bring us a requirement and we take it from concept to a tested prototype, with fixed stages and a review at each one.
For manufacturers and integratorsWe share engineering effort, test results and intellectual property on terms agreed before work starts.
For companies with their own engineering teamsSend us an existing aircraft or subsystem for structured trials and an independent written assessment.
For buyers and programme officesWe connect vetted organisations with Ukrainian companies for co-production, licensing or supply, and stay involved while the relationship gets established.
For companies entering or sourcing from Ukraine
Defense Systems is a research and development company focused on unmanned aircraft. We keep the team small, test early, and write down what we find so clients can act on it.
No. We design, prototype and test. When a design is ready we hand it over with the files and test data needed for production, and can introduce manufacturing partners.
Ownership is agreed in writing before work starts. In contract R&D the client normally owns the result. In joint development it is shared on the terms we set together.
We work with Ukrainian manufacturers, engineering firms and test teams on development and trials, and we introduce vetted organisations to them for co-production and supply.
No. That work is for government bodies and authorised organisations only, and it proceeds once the required licences and end-user documents are in place.
Yes. We sign a non-disclosure agreement before technical details are exchanged, and we share nothing with partners without your agreement.
