Additional: Just seen the news about Berdyansk air base.
This is big for 2 reasons.
A: if it really was ATACMS then they’ve been deployed incredibly quickly, the US only agreed to send them on Sept 24th. I guess they’re pretty ‘plug and play’ with the HIMARS / M270 platforms which helps.
B: Russia’s fleet of KA-52 attack choppers has been a major factor in slowing Ukraine’s advance, especially by attacking armored columns, something they excel at. Russia started the war with 133 of them and at least 43 of them have already lost in action.
If Ukraine just took out another 5-10 with that strike that’s still a massive chunk of Russia’s entire remaining fleet. Berdyansk would also have been the main base where they’d be supporting the Zaporizhia/Tokmak front from.
Russian telegram channels are reporting that this is the most serious single loss of Russian aviation so far in the war, obviously we don’t have the details yet but this could turn out to be a huge deal.
