The Fourth Law (TFL), a defense technology company headquartered in Kyiv, founded by entrepreneur Yaroslav Azhnyuk, has announced its first round of funding from a group of venture capital funds and angel investors from the EU, the US, and Canada.
In addition, TFL has publicly revealed its products for the first time. One of them is the TFL-1 autonomy module. It gives drones the ability to fly autonomously on the last leg of the journey and cruise. The company claims that the module is designed so that it can be produced in volumes of hundreds of thousands of units per month, and the price allows it to be installed on every FPV drone.
The developer also supplies Lupinis-10-TFL-1 – both a UAV (standalone drone) and an UAV (unmanned aerial vehicle complex), which consists of one hundred 10-inch FPV drones with TFL-1 autonomy, a ground control station, and auxiliary equipment.
"These drones are capable of reaching targets within 30 kilometers with a payload of 1 kg, and a maximum payload of 3.5 kg at shorter distances. Aside from the Lupynis platform, TFL-1 is integrated in over a dozen major FPV manufacturers’ drones. The company offers Lupynis-10-TFL-1 UAS to the Government and Defense Forces while the TFL-1 module, through licensing, is available to other FPV manufacturers," the developer noted.
TFL products have undergone the codification procedure and are used by units in the Armed Forces of Ukraine.
The company says these first products significantly increase the success rate of FPV drone missions while increasing their cost by only 10-20%. This is made possible by transferring control of the drone for the last 500 m of flight to an on-board computer that works with artificial intelligence algorithms.
TFL explained that this "last mile" autonomy approach overcomes electronic warfare, radio horizon interference, and improves pilot efficiency. The product is already being successfully used by the Ukrainian Defense Forces.
The "Fourth Law" also emphasized that over several years of development and testing by the Armed Forces, the developer managed to create a multi-level artificial intelligence system that is capable of determining the type of stationary or moving target and flying precisely to the center, despite various obstacles.
Now, the company has shown a video of its autonomous system in action for the first time. In a Facebook post, Yaroslav Azhnyuk writes that this is perhaps "the first public video in the world of the mass application of AI for FPV guidance."
"Since March 2025, pilots of the 58th Separate Motorized Infantry Brigade have been utilizing aircraft equipped with the TFL-1 system, which has demonstrated its effectiveness on the battlefield during this period. It helps us overcome electronic warfare, jamming, acquire, and strike targets in challenging conditions. Its capabilities are most notably demonstrated during special missions. Our operational experience confirms it as a truly effective system," said Colonel Ruslan Shevchuk, commander of the 58th Separate Motorized Infantry Brigade of the Armed Forces of Ukraine.
The "Fourth Law" assumes that in the next decade, autonomous robots will transform industries, including defense, transportation, agriculture, construction, and more.
