Loud noises were reported over Kursk, Russia, between 7:16 PM and 8:15 PM UTC on February 8, 2026, according to an X post by Typical Kursk received in the 59-minute window. Separately, Russian Armed Forces announced mass production of the 'Kaplya' (Drop) payload for FPV drones, capable of penetrating over 100 mm of armor, per Btvt.info. The Typical Kursk post stated 'Loud noises over Kursk!' with a note for maximum distribution, indicating potential explosions or military activity in the city during this period. No further details on the source or nature of the noises were provided in the post. Btvt.info reported the 'Kaplya' payload as a multi-purpose explosive formed penetrator (EFP) with an estimated 150 mm warhead, designed to punch through cage armor ('barbecues') and ERA without triggering it, while producing fragments for anti-infantry effects against AFVs and pickup trucks. The payload maintains effectiveness at distance and allows target changes mid-flight, with units already sent to troops.
