Major-General Igor Konashenkov, spokesman for the Russian Ministry of Defense, said that the American destroyer McCampbell proceeded at least 100 kilometers from Russian territorial waters.
The Russian Defense Ministry also noted that the movement of the American destroyer was under the constant control of Russian warships and aircraft of the Pacific Fleet.
According to Konashenkov, as soon as the McCampbell crew realized that he was being “patronized”, he gained momentum and now prefers to “demonstrate” his courage at a distance of more than 400 kilometers from Russian territorial waters.
Thus, as a result of the actions of the Russian fleet, it was experimentally established that the "immediate proximity" with which the Americans decide to "challenge the excessive sea claims of Russia" is somewhere in the range from 100 to 500 kilometers to Russian territorial waters.
In this situation, it is not surprising that Russia often does not even suspect that the US Navy is challenging it.
