Threod Systems

Threod Systems is an Estonian defence technology company founded in 2012 and headquartered in Viimsi parish, Harju county, Estonia. The company specialises in high-capability systems designed to support tactical effectiveness and operational safety, with a mission to enhance battlefield situational awareness through reliable, combat-proven solutions. Its operations span three core product areas: Eos unmanned aircraft systems (UAS) for long-range surveillance and target acquisition, eOpic electro-optical systems (lightweight payloads with high-performance sensors and image stabilisation), and Cata aircraft launcher systems (pneumatic launchers for one-way effectors and target drones). Threod Systems' products are actively used in 32 countries, including 18 NATO member states and Ukraine. The company reports that its systems have been proven through thousands of hours in real combat, and that its products are designed in-house by a team of over 200 professionals. It holds certifications including ISO 9001:2015, AQAP 2110, ISO 14001:2015, and ISO/IEC 27001, reflecting its focus on quality, security, and environmental management. The company's UAS development focuses on fixed-wing aircraft with integrated vertical take-off and landing (VTOL) capability, as well as conventional quadcopters and aircraft-like unmanned aerial vehicles such as the Stream C VTOL. Threod Systems collaborates with several Estonian entities, including Milrem Robotics, the Estonian Aviation Academy, and Tallinn University of Technology, as well as the Estonian Ministry of Defence and the Estonian Defence Forces. It also works with the US-based military company Momentum Aerospace Group. In cooperation with the Estonian government, Threod Systems' drones have performed various operations, such as monitoring the Estonian-Latvian border. Its unmanned aircraft have also assisted medical workers, for example by transporting a COVID-19 patient sample from Hiiumaa to the mainland, a flight lasting about 27 minutes compared to over an hour by ferry. The company exhibits at international defence events, including the Estonian Defence Week in Tallinn and AFRIDEX in Lagos, Nigeria.

Threod Systems was founded in 2012 in Estonia as a defence technology company. From its base in Viimsi parish, Harju county, it grew into a developer and manufacturer of unmanned aircraft systems (UAS), electro-optical ISR and target acquisition solutions, and launcher systems for one-way effectors. The company's early focus was on fixed-wing unmanned aerial vehicles with integrated vertical take-off and landing (VTOL) capability, alongside conventional quadcopters and aircraft-like drones such as the Stream C VTOL. Over the years, Threod Systems expanded its product portfolio into three core areas: Eos UAS for long-range surveillance and target acquisition, eOpic electro-optical payloads with high-performance sensors and image stabilisation, and Cata pneumatic launcher systems for rapid deployment of one-way effectors and target drones. The company reports that its systems are actively used in 32 countries, including 18 NATO member states and Ukraine, and have been proven through thousands of hours in real combat. Its products are designed in-house by a team of over 200 professionals. Threod Systems has established partnerships with several Estonian entities, including Milrem Robotics, the Estonian Aviation Academy, and Tallinn University of Technology, as well as the Estonian Ministry of Defence and the Estonian Defence Forces. It also collaborates with the US-based military company Momentum Aerospace Group.
