Thales Launches the LGR275 Proxy, a Proximity-Fuzed 70mm Laser-Guided Rocket for Low-Cost Counter-Drone Engagements

Technical Summary

At Eurosatory 2026 in Paris, Thales has launched the LGR275 Proxy, a 70mm (2.75-inch) laser-guided rocket configured specifically for the counter-Unmanned-Aircraft-System (counter-UAS) role. The munition builds on Thales Belgium's established FZ275 Laser-Guided Rocket (LGR) family, pairing the proven semi-active laser homing seeker with a proximity sensor and a military-grade warhead optimised for aerial targets, and is offered for both air-to-air and surface-to-air employment. Thales Belgium describes itself as the lead European producer of NATO-standard 70mm rockets and states it plans to triple laser-guided-rocket production between 2026 and 2028.

The design rationale is economic as much as technical. Thales frames the LGR275 Proxy as a response to the cost imbalance between cheap Class 1 and Class 2 drones and the expensive interceptors used against them, a mismatch that depletes stockpiles and strains air-defence budgets in high-intensity drone warfare. A guided 70mm rocket sits between unguided rockets and full surface-to-air missiles on the cost curve, offering far lower unit cost than a missile while retaining semi-active laser homing accuracy. The Proxy designation reflects the central change from earlier LGR variants: a proximity-fuzed warhead in place of point-detonation, which is the key enabler against small aerial targets.

Building on our already proven laser-guided rocket solutions, Thales provides a solution to strengthen nations defence readiness against the drone threat, one of the key challenges of our times. Thales Belgium is the leader in NATO standard rockets and our solid production ramp-up allows us to meet the needs of the armed forces. Alain Quevrin, Country Director, Thales Belgium and Luxembourg

Analysis of Effects

Against a small drone the limiting factor is miss distance. An unguided or point-detonating 70mm rocket must achieve a near-direct hit to defeat a target a few tens of centimetres across, which is difficult given the closing geometries and the small radar and optical cross-sections involved. A proximity sensor changes the kill mechanism from impact to fragmentation at an optimised stand-off, so the warhead need only pass within its lethal radius rather than strike the airframe. Combined with semi-active laser homing, which holds the rocket on a designated aim point through flight, this is what converts a legacy ground-attack rocket into a credible air-target weapon.

The LGR275 Proxy enters a fast-filling field. The Advanced Precision Kill Weapon System (APKWS), BAE Systems' laser-guided 70mm rocket, was highlighted by the Royal Air Force this month for Typhoon counter-drone use, and several NATO states are converting Hydra 70 stocks to guided counter-air roles. Thales Belgium's claimed production tripling to 2028 is the more strategic signal than the round itself: the European bottleneck in this segment is guided-rocket throughput, not concept. Whoever can build laser-guided 70mm rockets at volume and low unit cost will shape how the alliance absorbs the drone threat over the next several years.

Personnel and Safety Considerations

As a complete guided rocket with a rocket motor and an explosive warhead, the LGR275 Proxy is an all-up round subject to the full ordnance regime, unlike the inert small-arms natures sometimes grouped under counter-UAS. Hazard classification will depend on the warhead fill and motor, with complete 70mm rockets typically falling in Hazard Division 1.1 or 1.3 depending on configuration; Thales has not published the figure. A proximity-fuzed air-target warhead raises specific safety considerations of its own: fuze arming distance, fallback or self-destruct behaviour for rounds that do not acquire a target, and the ground-fall footprint of fragments and unexpended rockets in the surface-to-air mode. These must be defined in the safety case before any employment near populated areas.

Data Gaps

Key parameters remain undisclosed: warhead type, fill and Net Explosive Quantity (NEQ); the proximity-sensor technology, whether radio-frequency or optical, and its trigger radius; effective range and engagement envelope against Class 1 and Class 2 drones; guidance accuracy or circular error probable; whether the airframe reuses the FZ275 LGR body or is a new build; the launcher and platform set cleared for the air-to-air and surface-to-air modes; and unit cost and any launch-customer order. The production-tripling figure should be read as a target rather than confirmed capacity until order backlog is visible.
