The Kremlin is well aware of the capabilities of Ukrainian long-range weapons but is unable to defend the entire territory of the country. Most of the air defense systems are concentrated around Moscow.I would like to remind you that Ukrainian drones struck oil refineries in Ukhta and Tyumen. The distance to the targets in these cases was about 2,000 km.The Russian dictator perfectly understands that not only the range of target engagement has increased, but also the tactical and technical characteristics. Successful strikes by Ukrainian drones on air defense systems in Crimea and on Russian territory indicate the complete helplessness of Russian air defense. Moreover, Russia's radar systems are being destroyed.In the last two weeks alone, the Ghosts special unit of Ukraine's Main Intelligence Directorate has been striking Russian air defense systems in Donbas."According to the Main Intelligence Directorate, during these operations, intelligence officers hit two 48Ya6-K1 Podlyot radar stations and a 9A82 launcher from the S-300V anti-aircraft missile system."As a bonus, the intelligence officers sent a group of Russian servicemen and the KamAZ they were traveling in "to Kobzon" (a euphemism for killing them . ed.).Strikes are also being carried out on Russian air defense systems, which then allows for hitting important targets, both on the territory of the Russian Federation and in the temporarily occupied territories of Ukraine.A clear confirmation of the results of drone strikes on oil refineries in Russia, according to the Russian side itself, is that 38% of Russian oil refineries have partially or completely stopped operations.Thus, on the night of October 16, units of the Special Operations Forces struck the Saratov Oil Refinery in the Saratov region of the Russian Federation. The Saratov Oil Refinery is one of the oldest Russian oil refining enterprises, formerly known as the Cracking plant, and is part of the Rosneft oil company structure. The volume of oil refining as of 2020 was 7.2 million tons, and in 2023, it was 4.8 million tons.In addition, on the night of October 17, units of the Special Operations Forces used attack drones to strike a number of enemy targets in the temporarily occupied territory of the Autonomous Republic of Crimea. The successful actions of the Ukrainian forces resulted in damage to the oil depot in Gvardeyskoye and the Federal State Institution Gvardeysky combine in Karyernoye, Saky district.And on the night of October 27, units of the Special Operations Forces successfully struck supply facilities of the Russian army in the temporarily occupied territory of the Luhansk region of Ukraine. According to the press service of the Special Operations Forces, special forces hit a fuel and lubricants depot in Starobilsk and an oil depot in Luhansk with drones. It is worth noting that the Ukrainian drones struck the depot at the moment when the tanks were full, which amplified the "front strike" effect. "I would like to point out that amid successful Ukrainian UAV attacks, even from the north of Russia, air defense systems are being pulled towards the Moscow region."Arctic Tors have been noticed being transferred to the Moscow region to create the appearance of an echeloned defense. A map of the deployment of air defense systems in Moscow and the Moscow region was recently published. It includes S-300, S-400, Pantsirs, and Tors. That is, everything that the Russian Federation could gather from the vast country's reserves.The fact is that the Russian military-industrial complex currently has very limited capabilities for producing new air defense systems.This is evidenced by the statement of the Russian side that they are ready to buy back their own S-400 systems from Turkey, which were sold earlier. And a second very telling point: that the Russian Federation once again extended the agreement with India for the supply of S-400 air defense systems until 2027. The agreement initially provided for the supply of five S-400 installations by 2023. That is, all the statements of the Russian dictator that the Russian military-industrial complex is working in four shifts, and the production of the latest means of destruction and their air defense systems has increased, are nothing more than political statements that have no real basis.Specifically for EspresoAbout the author.
