Despite extensive promotion, laser weapons’ effective range still falls short of missile systems and is mainly designed for point defense.
The British DragonFire system has no official range; estimates suggest 3–5 km for destroying drones, rockets, and mortar rounds, potentially up to 10 km in ideal conditions.
US systems such as HELIOS and DE MSHORAD have ranges of 3–8 km, primarily targeting drones, fast boats, and some unguided munitions.
The main limitation is dependence on environmental conditions—fog, rain, dust, and smoke can significantly reduce power and range. Lasers must remain on a target for several seconds to destroy it.
Despite these constraints, the low cost per shot, high engagement speed, and virtually unlimited “ammunition” as long as power is available make lasers attractive for countering mass drone and cheap munition attacks.
