Special Report: U.S. firm supplied networking tech to maker of Russian missiles
WASHINGTON, Oct 12 (Reuters) - Since Russia annexed Crimea in 2014, American companies have been prohibited from dealing with MMZ Avangard, a state-owned firm that makes missiles for one of Russia's most sophisticated weapons, the S-400 air-defense system.
In a measure of Western concern about the S-400, the United States ejected Turkey, a NATO member, from a joint fighter jet program in 2019 after Ankara took delivery of the Russian system.
