In recent stage, Russia launched intensive air strikes on many regions of Ukraine. Russia has projected a large number of cruise missiles, tactical surface-to-surface missiles and suicide drones, and launched attacks on important Ukraine targets. Because Ukraine's air defense system is limited and is a major protection target, Ukraine suffered huge losses under Russia's saturation attack. The Ukrainian Kiev authorities have complained that the West has not provided enough air defense systems. At the critical moment, the United States has transferred the drone counter-system that was originally intended to be provided to Ukraine to the Middle East. For this reason, Ukraine is "injuring": The Russian-Ukrainian conflict has entered its fourth year. Judging from the strategic base of Ukraine's proactive attack on Russia, the conflict will not end in the short term.

The reason why Russia launched intensive air strikes was because of Ukrainian agents' sabotage activities in Russia, which had caused Russia to lose several Tu-95MS strategic nuclear bombs. After Ukrainian agents' sneak attacks, Russia has transferred some of its strategic nuclear bombs to the Far East, which is only 600 kilometers away from the United States. Obviously, the provocations of the Ukrainian Kiev authorities also made the United States feel huge pressure. Just when Russia was intensively storming air strikes in many areas of Ukraine, according to information released by Ukraine, the Ukrainian army shot down a Su-35 fighter jet of the Russian Air Force in the early morning of June 7. According to public information, since the outbreak of the Russian-Ukrainian conflict, Ukraine has shot down eight Su-35 fighters from Russia.

Su-35 is Russia's most powerful fourth-generation fighter. It is the ultimate improved model based on the Su-27 fighter. Because it has the performance of multiple fifth-generation fighter jets, it is called a 4++ fighter jet by Russia. Currently, Russia is promoting Su-35 fighter jets to the outside world. The Russian Warriors Flight Show Team has used Su-35 fighter jets for flight display, reflecting Russia's trust in Su-35 fighter jets. The Su-35 fighter jet is a single-seat model, with a very similar appearance to the Su-27 fighter jet, but the electronic equipment has undergone a lot of improvements, and it has strong comprehensive combat capabilities.

At present, the Ukrainian Air Force has equipped the F-16MLU fighter jets obtained from Europe. For this reason, the outside world has speculated that it is very likely that the F-16MLU fighter jets shot down Russia's Su-35 fighter jets. The Ukrainian Air Force's F-16MLU fighter jets have the ability to carry AIM-120 medium-range air-to-air missiles, and theoretically has the combat capability to intercept the Su-35. During the Russian-Ukrainian conflict, Western European countries provided Ukraine with a large number of F-16MLU fighters, thereby improving the comprehensive combat capability of the Ukrainian Air Force. Europe's F-16MLU fighter jets were introduced from the United States, representing the technical level of the 1980s. In terms of comprehensive strength, it is actually a big gap with the Su-35 fighter jets.

The Russian side has not yet responded to Ukraine's announcement of shooting down Russian Su-35 fighter jets again. Ukraine claimed that it was shooting down Russian Su-35 fighter jets while fighting against Russia's Kursk region. In fact, it is also possible that Ukraine's air defense missiles shot down Su-35 fighter jets. As early as 2022, Russia's Su-35 fighter jets were shot down by Ukraine's air defense system. At that time, Su-35 fighter jets and Su-30SM fighter jets were performing strike missions against Ukraine's air defense system, but unexpectedly they were counterattacked by Ukraine.
