It's unclear what military use the Mistral would add to the war in Ukraine, even with the planned Ka-52K helicopters. Dubbed the "Alligator," this chopper is primarily an anti-tank weapon, and is limited to less than 300 miles of range. If Russia were to escalate its involvement in Ukraine's war from supporting separatists to formal participation, Ka-52Ks could strike targets in Odessa and beyond. Or perhaps Russia would use them instead on the other side of the Black Sea, should tensions like the 2008 Russia-Georgia war flare up again. Presently, the Mistral-class ships wouldn't let Russia do all that much more in the wars it's most likely to fight, as Russia shares land borders with the neighbors they're most prone to invade.
