DIU spotted an unknown stealth drone twice
This week, Russian propagandists published a video of a Su-30 attack on boats carrying Ukrainian military. It claimed that the fighter jet had successfully hit the boat. The day before, the DIU issued a denial.
The video shown by military intelligence was filmed with an unknown stealth drone. The Su-30 pilot never spotted him. The video shows an attempt by a Russian fighter jet to hit one of the four boats with a missile. Fortunately, the Russian pilot did not hit the boat. In response, the Ukrainian military launched an anti-aircraft missile. The DIU claims that the enemy fighter was damaged and was forced to quickly return to the airfield.
A few hours earlier, the GUR published a video showing the destruction of the S-400 system in the western part of the Crimean peninsula. The strike was objectively monitored by a mysterious drone. The Russian SAM did not respond. As with the Su-30 pilot, he simply did not notice it.
Apparently, in both cases, military intelligence used a low-visibility drone that cannot be detected by regular radar.
