Fighterbomber is saying it could be one of the most serious strikes during the entire war. The previous record is held by Novofedorivka in 2022 with at least 7 military aircraft destroyed and 3–4 damaged. The helicopters have been key to Russia combating Ukraine's counter offensive and slowing it down. Russia has already lost around 40 Ka-52's during this war, visually confirmed losses, they're estimated to have around 133 so Ukraine could inflict a serious blow here.
The ATACMS is likely the cluster munition version as America didn't send the main version, if confirmed then it has already inflicted a serious blow within weeks (?) of it being sent! Storm Shadow blows up a submarine, ATACMS (may) have inflicted a serious blow to Russia's air-force, all shortly after being sent. Send Ukraine More Missiles! Taurus next.
