Epirus Leonidas (HPM)

Leonidas is a High-Power Microwave weapon — a short EM pulse that disables electronics in a 90° cone out to 1+ km. Especially effective against drone swarms, where a single pulse takes down dozens of quadcopters at once. US Army contracts (~USD 66 million 2023) for Phase III prototyping. Distinguishing capability versus laser: no per-target line-of-sight precision needed; one pulse for an entire swarm.
