Ukraine doesn't have much of a navy, but it's found a way to hunt down the 'weakest links' in Russia's critical sea supply lanes, UK intel says

• Ukrainian drones are attacking Russian ships and tankers, wrecking critical sea supply lanes. 
• The latest incident involved a drone hitting a Russian tanker near the Kerch Strait, UK intel said.
• Without a navy, Kyiv has increasingly relied on uncrewed surface vessels for its naval warfare. 

Ukraine doesn't have a naval fleet, but it's filling the gap with dangerous drones that terrorize Russian ships and disrupt critical sea supply lanes, especially in the Black Sea.
