The US Air Force carried out a risky operation against the Russian Crimea.
American experts say this is the first time in a long time that America has sent such a force to the Russian border.
Two long-range bombers with a range of 8,800 miles without refueling flew from an airbase in the UK towards Russia.
In flight, they were joined by British fighters, and Ukrainian Su-27s were nearby over Ukraine.
It was an extremely intense reconnaissance operation. Bombers, flying up to the Crimea, began to circle on the coast of the Azov Sea. And there were at least two RC-135V / W reconnaissance aircraft nearby, they recorded the radiation of Russian radars and other components of air defense systems.
As noted by American observers, intelligence was most interested in the parameters of the operation of the Russian S-400 and S-300, deployed at nine points in the region. However, American aviation did not dare to approach their potential enemy.
Russian aviation was raised into the air.
US aircraft flew 100 kilometers from the border of the DPR.
