A Ukrainian national has been sentenced to a 10-year jail term for an attempt to smuggle parts of a Russian S-300 anti-aircraft missile system into Ukraine, the press office of Russia’s Federal Security Service (FSB) told TASS on Monday.
In May 2018, Marchenko was assigned a task by Ukrainian Foreign Intelligence Service staffer Pyotr Khomenko to acquire klystrons in Russia - spare parts for S-300 anti-aircraft missile systems and received $163,000 for implementing the criminal intent, the statement says.
