The Ukrainians and Russians had a hectic weekend, so let’s get caught up.
On Friday, the Ukrainians used a naval drone (a motorboat loaded with a crap ton of explosives) to hit a Russian vessel in the port of Novorossiysk. These naval drones have been successful so far; just look at the Kerch Strait Bridge. However, a naval drone hitting Novorossiysk would signal a considerable range increase OR that a third party is involved.
