Thales FZ275 Laser-Guided 70 mm Rocket Heads for Ukrainian Production as a Mass Counter-Drone Effector

Technical Summary

Ukraine is to begin co-production of the Thales Belgium FZ275 Laser-Guided Rocket (LGR), a 70 mm (2.75 inch) precision rocket configured specifically as a low-cost counter-Uncrewed Aerial System (counter-UAS) effector against Shahed-type one-way attack munitions. Reporting by Militarnyi on 5 June 2026, drawing on Swedish public broadcaster SVT and on Thales material, states that part of a planned annual run of 100,000 rounds from 2028 will be assembled at Ukrainian facilities under a full technology transfer arrangement. The cooperation rests on a 2024 memorandum between Ukraine and Thales Belgium and a 2025 joint venture between Thales and the Ukrainian state holding Ukroboronprom.

The FZ275 LGR is the guided member of the long-established Forges de Zeebrugge (FZ) 70 mm rocket family. It adds a semi-active laser (SAL) homing seeker to the airframe of the unguided FZ90 rocket, converting a free-flight area weapon into a guided round capable of engaging point targets out to a stated range of about 3 km. The counter-drone variant pairs that guidance package with the FZ123 warhead, a pre-formed fragmentation design holding between 6,500 and 7,000 small steel pellets around an explosive charge of approximately one kilogram. Thales states the weapon was matured from development to first battlefield use in roughly twelve months with European Union financial support.

The FZ123 warhead contains between 6,500 and 7,000 steel pellets; when its charge of roughly one kilogram detonates near the target, the fragments scatter across the engagement cone to defeat the incoming drone. Militarnyi, citing Thales Belgium, 5 June 2026

Analysis of Effects

The terminal mechanism is fragmentation rather than blast. A pre-formed fragment matrix of 6,500 to 7,000 steel pellets, accelerated by an explosive charge in the order of one kilogram, generates a dense fragment cone intended to perforate the airframe, control surfaces or propulsion of a slow, non-manoeuvring target. The wording that the warhead detonates "near the target" indicates a proximity or command-airburst function rather than point-detonating impact fuzing, which is the expected solution for a counter-UAS round, because a direct hit on a small uncrewed target with an unfuzed-for-airburst warhead would waste most of the lethal pattern. Confirmation of the fuze type is a data gap.

The operational logic is cost-exchange. Engaging a one-way attack munition costing in the low tens of thousands of US dollars with a surface-to-air interceptor costing several hundred thousand to over one million US dollars is an unsustainable exchange ratio at scale. A 70 mm guided rocket sits far lower on that curve, and the FZ275 retains the magazine depth of an unguided rocket pod while adding the precision needed against a small target. The semi-active laser approach does, however, tie each engagement to a designating laser, which constrains the number of simultaneous shots to the number of available designation channels and demands an integrated fire-control and sensor chain on the Vampire launcher or host aircraft.

Personnel and Safety Considerations

The complete round combines a solid-propellant rocket motor with an explosive-filled fragmentation warhead, so storage and transport classification will be governed by the more hazardous of the two energetic fillings. Pending manufacturer data, the assessed Hazard Division is HD 1.1 if the warhead high-explosive fill governs, with HD 1.3 a possibility if the motor propellant governs and the warhead is shown not to mass-detonate; the Compatibility Group and Net Explosive Quantity (NEQ) per packaging configuration are not yet published. A technology-transfer and co-production arrangement also raises configuration-control, lot-acceptance and quality-assurance questions, since rounds assembled on a second production line must meet the same proof and surveillance standards as the parent line to remain interoperable and safe to store under AASTP-1 Edition C and the DSA 03.OME regulatory regime. The laser designation function additionally introduces an eye-safety control requirement during training and live firing.

Data Gaps

Outstanding items for any finished assessment: exact warhead explosive fill type and mass; rocket motor propellant type and mass, and the resulting NEQ; confirmation of the fuze type (proximity, command airburst or pre-set); Hazard Division and Compatibility Group per packaging configuration; insensitive-munition compliance status; the unit cost at scale; and the maturity and proof status of the Ukrainian assembly line relative to the Belgian parent line. The 100,000-rounds-per-year figure and the 2028 date are manufacturer plans, not contracted deliveries, and should be treated as forecasts.
