TheFourthLaw product offering
Product offeringCore offering
TheFourthLaw develops and sells AI-powered autonomous terminal guidance systems for FPV drones and UAVs. Its core offerings include the TFL-1 autonomy module (an add-on providing fire-and-forget guidance in the final 500 meters of flight), the Lupynis-10-TFL-1 integrated autonomous FPV drone, and the Zerov-8 autonomous interceptor for counter-UAV missions. The technology stack is sold as standalone hardware modules and complete drones to military units, government procurement agencies, and licensed to third-party drone manufacturers for OEM integration.
Product overview
The Fourth Law (TFL) is a defense technology company offering a modular autonomy platform for FPV drones and robotic systems. The core portfolio consists of the TFL-1 autonomy module (add-on for existing FPV drones), the Lupynis-10-TFL-1 integrated autonomous drone, and the Zerov-8 autonomous interceptor. The TFL-1 module provides terminal guidance (first-level autonomy) while the company is developing TFL-2 through TFL-5 for progressively higher autonomy levels. Software infrastructure includes simulation, analytics, and fleet management systems. All core products have received NATO codification and Ukrainian Ministry of Defense approval. The company follows a mass-deployment strategy, targeting production volumes of hundreds of thousands of units monthly.

Products and services
- TFL-1 Autonomy Module AI-powered autonomous terminal guidance and cruise module that transfers control to an onboard AI computer in the final 500 meters of flight, tracking the target outline and guiding the drone to its center. Designed as an add-on for FPV drones from major manufacturers; increases mission success rates by 2-4x while adding only 10% to unit cost. Available with twilight ($150), night 256 ($340), and night 640 ($620) camera configurations. Invulnerable to electronic warfare, ignores the radio horizon, supports 10-second pilot training, and includes cryptographic protection and over-the-air software updates.
- Lupynis-10-TFL-1 Autonomous FPV Drone First-level autonomy 10-inch FPV drone with integrated TFL-1 module. Strong carbon frame drone with 30+ km range carrying a 1 kg payload (up to 4 kg at shorter distances), 6s3p 20,000 mAh battery, and customizable connectivity. Codified by NATO and the Ukrainian Ministry of Defense. Priced $480-$960 depending on camera configuration. Available as singular units or as UAS packages of 100 units with ground control station and support equipment.
- Zerov-8 Autonomous Interceptor Autonomous aerial interceptor drone for counter-UAV missions. Features AI-based detection in thermal imagery at 2-3x greater distances than comparable systems, maximum speed of 326 km/h, target interception speed up to 270 km/h, combat radius up to 20 km, flight time up to 20 minutes, warhead capacity up to 0.5 kg, and detection range up to 1 km (300 m in difficult conditions). Uses TFL-AntiShahed detection module to identify hostile drones like Shahed and Geran faster than a human eye can see.
- TFL-AntiShahed Detection Module Standalone on-edge AI module for interceptor drones that detects and identifies hostile UAVs (Shahed, Geran types) faster than a human eye. Analyzes object movement, thermal signatures, and other parameters to highlight and stably track targets for pilots. Operates independently of flight path and integrates with the Zerov-8 interceptor platform.
Quantifiable outcome
- 2-4x increase in mission success rate with TFL-1 autonomy at only 10% cost increase

TheFourthLaw partnerships and signals
Strategic signalPartnerships
Ten partnerships are on record, tiered core and minor.
- RSI EuropecoreAt Eurosatory (world's largest defence technology exhibition in France), TFL signed MoU with Lithuanian RSI Europe to develop joint drone manufacturing in Lithuania under 'Build with Ukraine' framework. RSI Europe will prepare manufacturing facilities and produce thousands of drones using TFL technologies. Priority hiring for production will be given to Ukrainian citizens.
- IRONminorCo-organized 'Drone Autonomy 2026' event in Lviv with IRON, bringing together engineers, military personnel, manufacturers, investors, and government officials to discuss scaling autonomous solutions on frontlines.
- Odd Systems (Autonomy and Sovereignty Event)minorJointly hosted 'Autonomy and Sovereignty' closed-door event in Kyiv bringing together over 200 participants from Security and Defense Forces, government, Ukrainian and international industry leaders, defense innovators, and investors.
- VyriycoreVyriy, one of Ukraine's largest drone manufacturers, and The Fourth Law announced mass production of drones with TFL-1 terminal guidance. Vyriy-10 drone (one of the most successful FPV drones on the frontline) will be equipped with TFL-1 modules. The Vyriy-10-TFL-1 costs approximately UAH 18,500 (~$448 USD).

TheFourthLaw competitors and assessment
Company assessmentBroad incumbents
- Shield AI: US-based defense AI company building autonomous flight stacks (Hivemind) for drones and aircraft. Directly comparable to TheFourthLaw's autonomy software/module strategy but operating at much larger scale with US defense funding.
- Anduril Industries: US defense-tech prime building autonomous systems including the Lattice software platform and various UAS/UUV. Overlaps with TheFourthLaw's autonomy software roadmap and competes for allied defense AI procurement.
- Skydio: US autonomous drone manufacturer with strong on-device AI computer vision capabilities (Skydio Autonomy). Overlaps in GNSS-denied visual autonomy but focused on small commercial/enterprise UAS rather than FPV munitions.
Direct peers
- Auterion: Open-source drone operating system and autonomy stack vendor serving military and commercial UAVs. Closest direct competitor to TFL-1 module: both sell autonomy software that integrates across third-party airframes.
- DroneShield: Counter-UAS detection and defeat provider. Most directly comparable to TheFourthLaw's Zerov-8 autonomous interceptor and TFL-AntiShahed detection module targeting Shahed-type threats.
- Saker Robotics: Ukrainian drone autonomy startup also developing AI targeting/terminal guidance for FPV platforms; competing for the same Ukrainian military procurement budgets and BRAVE1 cluster support.
- D-Fend Solutions: Israeli counter-UAS and drone takeover vendor offering autonomous detection-and-defeat capabilities. Comparable to TheFourthLaw's Zerov-8 interceptor and counter-drone ambitions in allied markets.
Others
- Odd Systems: Ukrainian sister company co-founded by TheFourthLaw's CEO Yaroslav Azhnyuk; manufactures Kurbas thermal cameras and FPV drones and co-developed Lupynis-10-TFL-1. Strategic supplier and development partner rather than competitor.
- Vyriy: One of Ukraine's largest FPV drone manufacturers and a strategic licensing partner of TheFourthLaw. Comparable as a customer/integrator (Vyriy-10-TFL-1) rather than a competitor of the autonomy module.
Emerging players
- Swarmer: Ukrainian startup developing autonomous swarm coordination and target engagement software for drones. Comparable to higher-level ambitions in TheFourthLaw's TFL-4/TFL-5 roadmap (swarms, GPS-denied navigation).
