A Ukrainian underwater drone struck and critically disabled a Russian Project 636.3 Kilo-class submarine inside the Novorossiysk naval base. Ukrainian analysts say the strike effectively removes the submarine from service due to Russia’s inability to repair submarines in the Black Sea, while blast fragments from the explosion may have also damaged a second submarine moored nearby.

Ukrainian President Volodymyr Zelenskyy said Ukraine has moved significantly closer to securing NATO -style security guarantees and a reparations-based funding mechanism following two days of intensive talks with US and European partners in Berlin, describing the discussions as difficult but forward-moving.

Russia is trying to keep one of its most anachronistic battlefield platforms alive by adding artificial intelligence. According to  Defense Express , Moscow plans to equip its armored trains—relics of 20th-century warfare—with AI-powered camera systems designed to automatically detect and track Ukrainian drones, a move that underscores how vulnerable these rail-bound assets have become in the age of precision UAV strikes.
