HESA Shahed 136 (Persian: ???? ???) also known in Russian designation as the Geran-2, is an Iranian loitering munition autonomous swarm pusher-prop aerial drone in service since 2021, developed by Iran Aircraft Manufacturing Industries (HESA). At its core, it is designed to neutralize ground targets from a distance. The drone is fired in multiples from a ready launch rack (in batches of five upwards) and is designed to evade air defenses and overwhelm ground targets, consuming systems during the attack. The drone was revealed in December 2021 through published footage. The system is believed to first have been actively deployed to Houthi-controlled areas in Yemen, before being actively used by the Russian army during their invasion of Ukraine, from September 2022
