DR-L3 is an AI-powered 3 kW laser system engineered for rapid deployment and precision neutralization of low-altitude drone threats. This integrated platform combines an indigenous high-power single-mode fiber laser with multi-spectral (visible/IR) sensors and AI-driven autonomy. It delivers swift target neutralization (≤15 s) with pinpoint accuracy (beam deviation ≤3 cm at 500 m), effectively engaging even high-speed, maneuverable targets at ranges up to ≥800 m acquisition / ≤500 m strike. Designed for exceptional operational efficiency, it boasts an extremely low cost-per-intercept (~1 kWh electricity) and near-infinite "magazine depth" under sustained power and cooling. It offers superior stealth (silent, invisible strikes) and resilience in complex electromagnetic environments. With 4 hours standby, 15 s continuous lasing bursts, and 200 total engagement capacity.
