 Russia hunting for weapons system that downed three Su-34 strike aircraft. Russian forces are using drones to hunt for the Ukrainian weapons system that downed three Russian supersonic Su-34 strike aircraft. Speaking to national TV, Ukrainian Air Force spokesperson Yuri Inat said the Kremlin wanted to find the equipment from which their planes were sent into eternal flight. He added, Now the enemy using drones is trying to gather the maximum amount of intelligence in southern areas where the Russian fighter jets were brought down. Ukraine announced it had downed four Russian Su-34s, though the weapon system used has not been disclosed. Some military-themed telegram channels suggested the possible use of the Patriot anti-aircraft missile system. They are employed as launch platforms of guided aerial bombs and Kh-59 missiles which the Russians use to attack the Kursan region and other areas of Ukraine. The commander of the Ukrainian Air Force, Mikhail Oleshchuk, said the operation was payback for an earlier Russian drone attack on which one of the drones was written, Die, bitch, in Russian. In a telegram post, he wrote, Great idea, here's our answer. He added, Eternal flight, brothers. Inat added that since the downing of the aircraft, there had been fewer guided bomb attacks in the Kursan region but said more anti-aircraft weapons were still needed by Ukraine. The Air Force can conduct such operations in different sectors. He said, The only question is that there should be more of these systems and this issue is being discussed as part of our recently created Air Defense Coalition.
