The Fourth Law has codified its key products: the TFL-1 module and the autonomous drone

Ukraine has officially codified the first Ukrainian FPV drone with the first level of autonomy, Lupynis-10-TFL-1, and the TFL-1 autonomy module.

This was announced on social media by Yaroslav Azhnyuk, founder and CEO of The Fourth Law.

Both are key products of The Fourth Law (TFL). 

Azhnyuk noted that prior to codification, the drone and modules underwent joint testing by the National Guard of Ukraine, which confirmed their effectiveness and reliability.

According to him, the codification process for autonomous systems was more complex and time-consuming than for conventional FPV drones or fiber optic-controlled drones.

Preparation and testing took more than a week at the training ground, and the paperwork required a significant amount of time.

What preceded this?

In July 2025, Ukrainian defense technology company The Fourth Law (TFL) raised funding from a number of venture capital funds and private investors from the US, Canada, and the EU.

The amount of the deal and the names of the investors were not disclosed.

At the same time, Finnish-Ukrainian investment company Double Tap Investments announced its participation in The Fourth Law’s investment round.

“TFL is a team that has managed to combine deep engineering, advanced autonomy, and the harsh realities of the battlefield. They have developed not just another autopilot, but an adaptive system that works where there is no connection and every second counts,” said Oles Khudoba, co-founder of Double Tap Investments, at the time.

What is codification?

Codification of drones is the process of assigning them unique nomenclature numbers in a general classification system.

This allows the type of drone, its origin, manufacturer, and availability for purchase in the context of military procurement or civilian circulation to be identified.

TFL-1 Autonomy Module

A guidance system for FPV drones with AI that tracks the target’s outline and automatically guides the drone to its center. It has the highest hit rate among its counterparts and is compatible with most popular platforms.

Among the advantages:

  • Virtually invulnerable to electronic warfare, independent of radio horizon;

  • Increases pilot accuracy and efficiency;

  • Cruise mode helps to pass through areas of active interference (“curtain”);

  • Supports integration with MilBeta and CrashDetect.

Such systems cost from €162 to €702 (from 6 to 26 thousand hryvnias).
