Russian forces only deployed a few Shahed kamikaze drones at a time, but now there are up to 700 per night. In addition to terrorizing Ukraine's population, these drone swarms are pummeling its crucial arms industry.

The facility reportedly manufactures batteries for missile guidance and glider modules, including for the Iskander system and cruise missiles, which Russia has been increasingly using to target Ukrainian cities.

Russia fired a record 728 Shahed and decoy drones at Ukraine overnight, as well as 13 cruise and ballistic missiles, the Ukrainian air force said, in the latest escalation after weeks of mounting Russian aerial and ground attacks in the more than three-year war.
