 Su-34 mass crash. Russia has problems with smart bombs. Russia produces about one aircraft per month. The Ukrainian military needs to destroy two of three Russian fighter jets at a time so that Moscow cannot recover losses. According to verified data, during the entire time of the full-scale war in Ukraine, the Russian armed forces lost 25 Su-34 front-line underfighter bombers. At that, the last verification of losses is dated December 22, 2023. According to unverified data, the Russian air force has lost more than 50 Su-34s destroyed and damaged in two years, Ukrainian military analyst Oleksandr Kovalenko said. At the same time, he pointed out that as of the beginning of the full-scale invasion of Ukraine, the Russian air force had 110 Su-34s in service of which less than 100 were combat ready. Meanwhile, Russia continues to produce Su-34s and its potential is a squadron per year. That is 10 to 12 aircraft or one aircraft per month. In other words, if Su-34 losses are brought to the level of 2 to 3 aircraft per month, it will be impossible to compensate for their losses with their production and the total number will go into minus the expert explained. According to him, during the fall of the Su-34, there is a high probability of the pilot's death as well and his training takes 5 to 10 years of constant drills and practice. It is also interesting that even if the pilot manages to eject, it is not yet a fact that he will survive after landing. The fact is that Russian pilot's pilot seats are made as for people and when landing on the sinful earth, pilots often broke their necks, some broke their spine or limbs. All of the above suggests that with the stable firing off of Su-34s, at some point, the Russian AFU may have a problem with the main working bird used for strikes with smart bombs. Kovalenko concluded, Ukrainian army shut down 7 Russian fighters on the eastern front over the week.
