European UAS developer Quantum Systems and ADV Defense UAB, a Lithuanian defense company part of Teltonika IoT Group, have signed a Memorandum of Understanding (MoU) at the German-Baltic Defence Industry Conference 2025 in Vilnius, creating a framework for closer cooperation on unmanned systems in Lithuania and along NATO’s Eastern Flank. The agreement is designed to deepen German–Lithuanian industrial collaboration in defence technology and innovation, with a focus on market expansion, localization, and joint research and development.
The partnership aims to combine German and Lithuanian expertise to deliver mission-proven unmanned systems while strengthening the region’s defence industrial base. It also supports Quantum Systems’ long-term strategy to build a strong industrial presence on NATO’s Eastern Flank and to back the German combat brigade stationed in Lithuania. By partnering with ADV Defense, Quantum Systems signals continued investment in Lithuanian partnerships that support resilient supply chains, capability development, and European technological sovereignty.
“This partnership embodies what we believe in — cooperation, trust, and local value creation,” said Donatas Sirgedas, Managing Director of Quantum Systems Lithuania. “We are entering the Lithuanian market as a Lithuanian company – one that develops Lithuanian capabilities, and contributes to Europe’s collective security. Germany’s commitment to Lithuania’s defense is our foundation, and together we represent the best of both nations.”
“This MoU is about shared purpose and lasting impact,” added Martin Karkour, Chief Revenue Officer of Quantum Systems GmbH. “Our cooperation with ADV Defense will help accelerate the ability of deterrence at NATO’s Eastern Flank and deliver real capability to our partners on the ground. It’s a partnership of equals, rooted in trust and built for the long term.”
The signing underscores both companies’ commitment to contributing to Lithuania’s defence ecosystem and to strengthening European defence cooperation. It also reflects the collaborative spirit of the German-Baltic Defence Industry Conference and aligns with the motto “United for Security.”
