The rapid spread of small drones has created a growing challenge for air-defense forces. Many of the drones now used for reconnaissance, targeting, and attack missions cost only a fraction of the missiles often required to intercept them. This imbalance has forced militaries to search for lower-cost defensive options that can be deployed at scale without exhausting stockpiles or budgets.
A newly introduced guided rocket (LGR275 Proxy developed by Thales) was designed specifically to address that problem. The system combines laser guidance with a proximity-sensing capability intended to improve effectiveness against small, fast-moving aerial targets while maintaining a lower cost profile than traditional air-defense interceptors.
The weapon is based on a 70 mm laser-guided rocket architecture but incorporates a proximity sensor optimized for counter-drone missions. Conventional guided rockets often depend on a direct hit to destroy a target. In contrast, the new system can detect when it is close enough to a drone and trigger its warhead at the most effective moment, increasing the probability of a successful interception.
This capability is particularly important when engaging small, unmanned aircraft, which can be difficult to strike directly due to their size, speed, and maneuverability. According to Interesting Engineering, by combining precision laser guidance with proximity-based detonation, the rocket is designed to improve engagement effectiveness against Class 1 and Class 2 drones.
Another notable feature is operational flexibility. The rocket supports both surface-to-air and air-to-air engagements, allowing it to be integrated into different defense architectures. Rather than replacing high-end interceptors, it is intended to complement them as part of a layered approach in which lower-cost threats can be engaged with more economical weapons.
From a defense perspective, the system reflects a broader trend toward sustainable counter-drone strategies. Recent conflicts have highlighted how large numbers of inexpensive drones can place significant pressure on traditional air-defense networks. Matching every drone with a costly missile is often neither practical nor economically sustainable.
The rocket is also expected to become part of a larger integrated air and missile defense architecture, providing an additional interception layer between electronic warfare systems and more advanced missile defenses.
As drone threats continue to evolve, defense planners are increasingly focused not only on whether a target can be intercepted, but also on whether it can be intercepted at a cost that remains sustainable during prolonged operations. The new guided rocket is designed with that balance in mind.
