Russia launched a widespread series of missile and drone attacks across Ukraine on August 21st, prompting Poland to scramble fighter jets. Multiple Ukrainian regions, including Zhytomyr, Vinnytsia, Cherkasy, Chernihiv, Sumy, and Dnipro, reported incoming cruise missiles and drones, according to Ukrainian Air Force and other local reports. The attacks involved multiple waves of cruise missiles targeting various locations, with reports of missiles detected in Zhytomyr, Vinnytsia, Cherkasy, and Chernihiv regions, and moving towards Khmelnytskyi and Lutsk. Russian strategic aviation, including Tu-95MS and Tu-160 aircraft, were involved in the strikes, with some landing back in Engels. The attacks also included Shahed drones targeting Chernihiv, Kyiv, Zhytomyr, and Volyn regions, as stated by Ukrainian Air Force. In response to the long-range aviation activity and missile strikes on Ukrainian territory, Poland's Air Force aircraft operated alongside allied aviation, launching all available forces and funds. Air defense systems and radar diagnostics were brought to the highest state of readiness to ensure the security of Polish territory and citizens, particularly in border areas, according to the Polish Armed Forces Operational Command. In Russia, energy block No. 7 of the Novovoronezh NPP was temporarily disconnected from the network due to an attack, though Rosenergoatom stated there were no security threats. Reports also indicated an impact on the traction substation of Zhuravka in the Voronezh region. Meanwhile, the crew of the frigate "Marshal Shaposhnikov" of the Pacific Fleet reportedly performed firing of Kaliber and Uranus cruise missiles. ATESH agents surveyed key logistics sites for the Russian Black Sea Fleet in Sevastopol, including the 810th Brigade’s fuel depot and the "Khersones" airfield.
