According to several Russian media outlets, Russian Navy Su-24 Fencer jets “forced” a U.S. Navy destroyer to head towards neutral waters after it was noticed by Russian Black Sea monitoring stations heading into Russia’s territorial waters.
Reportedly, the U.S. Navy destroyer USS Ross was heading directly towards Russian waters after leaving the Romanian port of Costanta. Russian Su-24s were scrambled towards the warship.
After the close encounter with the Su-24 jets, the destroyer “then turned around and left for neutral waters,” says RT, suggesting an unlikely violation of the Russian territorial waters by the U.S. warship.
“It seems that the Americans did not forget the April 2014 incident when one Su-24 actually shut down all equipment on the new USS Donald Cook American destroyer with anti-missile system elements,” an unnamed source said to Sputnik News.
