Elbit's Hermes 900 Kochav is an Israeli medium-altitude long-endurance UAV family with 36-hour endurance, a 350 kg baseline payload, and modular ISR, electronic-intelligence, communications-relay, maritime-patrol, and wide-area surveillance payload options. First flown in 2009, it entered Israeli combat use during the 2014 Gaza War and has since appeared in Azerbaijani and Israeli conflict documentation, while the StarLiner branch adds civil-airspace certification and heavier payload capacity for non-segregated airspace missions.

Mission Configuration

The Hermes 900 record splits between a military MALE UAV baseline and StarLiner civil-airspace derivatives. Elbit's baseline page emphasizes persistent multi-payload operation, while its StarLiner material adds certification and safety features for non-segregated airspace.

Baseline mission set

ISR, target acquisition, maritime patrol, communications relay, electronic intelligence, electronic warfare, and wide-area surveillance payloads.
