Defense Express editor-in-chief Oleh Katkov stated this on Espreso TV."The RT-70 radio telescope was destroyed by aircraft‑type FPV drones. These have long been used by the Ukrainian Defense Intelligence special unit Phantoms. It is this unit that regularly and methodically destroys radar stations and surface‑to‑air missile systems in occupied Crimea.Recently, in the Sea of Azov, the same aircraft‑type FPV drones struck the Buyan‑M — a small missile ship. And this weekend a video was published showing another batch of radar stations hit, including radars for the S‑400. And even the intelligence did not emphasize this: among the targets a radio telescope was struck — a real radio telescope that, in Soviet times, helped study Venus and Mars," Katkov said.According to the military expert, if the Russian forces had not annexed Crimea in 2014, the radio telescope would have continued to carry out exclusively scientific missions. But the Russians turned the space observatory near Yevpatoria into a research center for the so‑called Russian Aerospace Forces."The RT-70 radio telescope, built in Soviet times, was used to control and communicate with GLONASS satellite systems — the Russian analogue of GPS. Moreover, the Russians boasted that thanks to the use of the RT-70, GLONASS accuracy increased by 30%. That is an extremely high figure when it comes to a satellite navigation system.Ukrainian drones have attacked this facility more than once. But this time it was the RT-70 radio telescope that was struck. The diameter of its parabolic antenna is 70 meters.Only two such devices were created in Soviet times: one for the observatory near Yevpatoria, the other for the observatory near Ussuriysk. So only one remains in the Russian Federation," Katkov emphasized.On Monday, September 1, Ukrainian fighters launched a drone strike on a Russian airbase in the temporarily annexed Crimea, hitting two Mi-8 helicopters and a vessel.
