Among the 1,300 new models of weapons and military equipment developed and codified since the start of Russia's full-scale invasion of Ukraine, the largest category consists of UAVs and their ammunition.

Russia launched 112 Shahed attack drones and decoy UAVs of various types against Ukraine on the night of 6-7 February. Ukrainian air defence managed to down 81 drones, while 31 failed to reach their targets.

Officials say a Russian drone has blasted a hole in an apartment building in northeastern Ukraine during a nighttime attack that killed at least six people and wounded nine others.
