Kolibri 10 Advance: Ukraine's Certified FPV Now Locks On and Finishes Strikes Alone

Main Story

The Ukrainian drone industry has reached a notable engineering threshold: a mass-produced FPV airframe and an AI guidance module, developed by two separate companies, have been co-certified as a single orderable system. The Kolibri 10 Advance — produced by TAF Industries and fitted with The Fourth Law's TFL-1 autonomy module — is now available to Ukrainian defence forces through the DOT-Chain system, the Brave1 Market platform, and the eBall procurement programme.

The partnership began this spring. TAF Industries, a Kyiv-based manufacturer whose Kolibri FPV lineup has been codified to Ukrainian Ministry of Defence standards and assigned NATO Stock Numbers, supplied the airframe. The Fourth Law, a defence-tech startup that has been licensing the TFL-1 module to over a dozen Ukrainian FPV producers since at least mid-2025, supplied the guidance stack. According to TAF Industries' FPV product owner Andrii Atamanenko, frontline pilots had repeatedly requested drones equipped with TFL-1 modules, citing the module's battlefield-validated performance as the primary driver of the partnership.

The engineering distinction of the Kolibri 10 Advance matters more than the headline. This is not an autonomous hunter: a human operator must find, designate, and commit to a target before the machine takes over. What the TFL-1 adds is persistence through the most vulnerable phase of an FPV mission — the terminal dash. Once the operator locks onto a target from up to 1,000 metres away, the drone switches to autonomous mode and can complete the strike even if communications are completely severed. That capability directly addresses a critical limitation of conventional FPV drones operating under dense electronic warfare, where signal loss in the final approach typically causes the platform to fall inert.

The drone also includes a cruise mode in which it autonomously holds a set course, altitude, and airspeed without continuous operator input, allowing it to traverse jamming-dense corridors before the terminal engagement phase begins. The Fourth Law describes this combination as Level 1 autonomy — the first rung of a publicly documented five-stage roadmap that ultimately envisions GPS-denied navigation, autonomous target detection and engagement, and autonomous take-off and landing capability.

There is a noteworthy discrepancy in the reported range figures that warrants transparency. Militarnyi, citing The Fourth Law directly, reports a maximum reach of over 40 km, attributed to dual-band communications and a high-capacity battery. Specifications shared by the two companies with The Defender list a strike range of 15–30 km, with the figure varying by warhead weight. Both numbers are potentially consistent: the 40 km figure likely reflects a lightly loaded or optimised configuration, while the 15–30 km band represents the operational envelope across the full payload spectrum as specified on TAF Industries' product page.

The scale at which TFL-1 is already being deployed is significant context. The Fourth Law had already announced mass-production partnerships with Vyriy, one of Ukraine's largest FPV manufacturers, in September 2025, and the module has since been integrated by more than a dozen Ukrainian FPV producers. The Kolibri 10 Advance represents the module's most recent — and most publicly certified — integration.

Technical Breakdown

• Platform / UAV class: Quad-rotor FPV strike drone (kamikaze/loitering munition configuration), 10-inch propeller class
• Airframe: TAF Industries Kolibri 10 Advance — reinforced frame, codified to Ukrainian MoD standards, assigned a NATO Stock Number
• Payload: 1–4 kg, configurable by mission; range scales inversely with payload weight
• Strike range: 15–30 km (manufacturer spec via The Defender, payload-dependent); up to 40+ km reported by Militarnyi in a lighter-load configuration
• Altitude ceiling: Up to 2,000 m
• Propulsion: Electric multi-rotor; high-capacity battery enabling extended range
• Communications: Dual-band; MilELRS firmware for EW-resistant, encrypted signal transmission; support for non-standard video frequencies
• Sensors / optics: Configurable for daytime, night-vision, or digital camera payloads
• Autonomy module: The Fourth Law TFL-1 — AI-based terminal guidance and cruise mode
• Autonomy level: Level 1 (The Fourth Law classification) — operator designates targets moving at up to 80 km/h from up to 1,000 m; drone then executes terminal phase autonomously, including under complete communications loss
• Procurement: Available via DOT-Chain, Brave1 Market, and eBall programme

Industry Impact

For manufacturers: The Kolibri 10 Advance is a template for a new product architecture in the Ukrainian FPV market: airframe manufacturers pair with AI module vendors through licensing agreements rather than building proprietary guidance stacks. The Fourth Law's module is already licensed to over a dozen producers, meaning the pattern is repeatable and scalable. TAF Industries gains a product that directly addresses the most common frontline request — EW resilience in the terminal phase — without redesigning its core platform.

For operators and integrators: The cruise mode and terminal lock mean FPV teams can now prosecute targets at ranges and under jamming conditions that would have required fibre-optic tethers or GPS-reliant systems. The system's availability on standard procurement platforms (DOT-Chain, eBall) lowers acquisition friction and puts it within reach of units without specialist procurement relationships.

For regulators and standards bodies: The co-certification of an airframe and a third-party AI guidance module as a single procurable unit is a regulatory model with implications beyond Ukraine. It demonstrates that a modular AI-plus-airframe certification pathway is operationally viable, raising questions for certification frameworks in NATO member states about how to evaluate composite systems where the autonomy stack is developed and updated independently of the airframe.

For investors: The Fourth Law has already secured an investment round with participation from Axon, the American public safety technology company, and has articulated a five-stage autonomy roadmap extending to GPS-denied navigation and full autonomous launch-and-recovery. The Kolibri integration validates the licensing model commercially, with the TFL-1 designed for mass production at volumes of hundreds of thousands of units per month, while adding only 10–20% to platform cost — a margin profile that supports broad adoption across high-volume FPV supply chains.
