Harpya / Erevos Drone Killer System

HARPYA is a “fire and forget" type semi-autonomous system designed to destroy hostile UAVs within a certain volume of air space.

The system comprises of two elements:
[1] the unmanned, high speed aircraft- missile HARPYA and
[2] the ground based EREVOS station.

The EREVOS is a portable field deployable detector, operational even squad and above tactical level, equipped with an array of sensors which assist an operator to locate an incoming threat target.

The HARPYA is a semi-autonomous high-speed ground-to-air unmanned aircraft missile which uses advanced AI and image processing technology to home-in to target UAV and destroy it by means of either proximity sensor activated explosion or by direct impact and explosion.
