Background

The Fourth Law partnered with RSI Europe at Eurosatory on 18 June 2026, signing a memorandum of understanding to establish joint drone production in Lithuania under the Build with Ukraine framework. Under the arrangement, The Fourth Law contributes AI software, computer-vision algorithms, and manufacturing expertise; Ukrainian citizens receive priority for production jobs. The agreement extends an existing pattern: the company already collaborates with Vilnius-based manufacturer Vyriy on volume production of its autonomous drone systems.

Founded in 2023 in Kyiv by entrepreneur Yaroslav Azhnyuk, The Fourth Law develops AI-driven autonomy modules for FPV drones. Its flagship product, the TFL-1, is an onboard computer running machine-vision algorithms that takes control during the final 500 metres of flight. The system operates on a fire-and-forget principle: once the target is visually acquired, it guides the drone to impact regardless of electronic-warfare jamming or signal loss. The TFL-1 module has received NATO codification. A follow-on bombing module, the TFL-2, launched in 2025. The company is backed by Axon and has received an initial funding round.

The Fourth Law represents a new class of Ukrainian dual-use technology exporter: rather than shipping finished hardware, it transfers autonomy software and production knowledge into allied-country facilities. This model sidesteps the legal and logistical constraints on exporting finished weapons from an active conflict zone, and positions Ukrainian AI expertise as a durable asset within NATO's defence-industrial base long after the war ends.

Common Questions
What does The Fourth Law's TFL-1 module do?
The TFL-1 is an onboard computer that takes control of an FPV drone during its final 500 metres of flight. Using machine-vision algorithms, it tracks and intercepts targets autonomously even when electronic-warfare jamming breaks the operator's radio link, operating on a fire-and-forget principle.Source: TechUkraine; The Fourth Law blog
Is The Fourth Law a Ukrainian company?
Yes. The Fourth Law was founded in Kyiv in 2023 by Yaroslav Azhnyuk. It develops AI autonomy modules for FPV drones and has received NATO codification for its TFL-1 module. It is backed by investor Axon.Source: TechUkraine; Ukraine's Arms Monitor
What is the Build with Ukraine drone framework?
Build with Ukraine is a model that transfers Ukrainian drone manufacturing know-how into allied countries. The Fourth Law and RSI Europe used it to establish a joint production facility in Lithuania in June 2026, keeping manufacturing inside the EU while using Ukrainian AI expertise.Source: defence-industry.eu, June 2026
