Russian publications, citing their sources, stated that the ship “Dupuy de Lome” of the French Navy attacked the radar stations of S-400 SAM system deployed in the Crimea by creating interference.
Certain frequencies were chosen for the attack. The authors of the material believe that this became possible due to obtaining by the Western military information about the frequencies used by the Russian radars. Journalists believe that the data was obtained by NATO during reconnaissance flights previously conducted by the U.S.
The article states that the French reconnaissance vessel sailed through the Bosporus Strait and then sailed to the central area of the Black Sea. The ship has no weapons but is equipped with various radio transmitting equipment that can interfere and collect various data.
