Drones are playing a big role in the Nagorno-Karabakh conflict between Armenia and Azerbaijan. Israeli, Turkish, Russian and locally produced drones and loitering munitions figure in the conflict and account for most losses especially by Armenia, which has lost armored vehicles, multiple rocket launchers and air defense platforms.
Azerbaijan says it also has taken out an Armenian S-300 surface to air missile system, using an Israeli Harop. Armenia denies the claim.
The Harop is a "suicide drone" manufactured by Israel Aerospace Industries (formerly Israel Aircraft Industries) and is classified as a loitering munition. Harop is an anti-radiation drone that can autonomously home in on radio emissions and is optimized to go after air defense systems.
Sometimes also called Harpy 2, Harop features a stealthy airframe design making its detection and interception by enemy air defenses difficult. It also has a low thermal signature, meaning that IR weapons can't effectively track Harop, and its sleek body makes visual location and identification difficult.
