According to an Ukrinform correspondent, the video of the July attack shows the pilot's screen in the moments before the drone, called a "Sea Baby," delivered up to 850 kilograms of explosives to one of the bridge's concrete support pillars.
Other surveillance videos also show the moment of impact of one drone on the road section of the bridge, and then another drone blast hitting the railway section.
According to the head of the SBU, Vasyl Maliuk, the Sea Baby was the result of months of development that began just after the invasion. "Sea surface drones are a unique invention of the Security Service of Ukraine," he said. "None of the private companies are involved. Using these drones we have recently conducted a successful hit of the Crimean bridge, the big assault ship Olenegorsky Gornyak and SIG tanker."
