Russia has deployed aircraft armed with hypersonic missiles along the Baltic Sea, a move that inches the country's forces closer to its NATO border, The Associated Press reported. In a Thursday announcement, the Russian Defense Ministry revealed that it moved three MiG-31 fighters brandishing Kinzhal missiles to Chkalovsk air base in Kaliningrad — a Russian enclave north of Poland and south of Lithuania. Moscow asserts that the Kinzhal missiles, which have already been used in its ongoing invasion of Ukraine, have a range of up to roughly 1,250 miles (2,000 kilometers) and fly at ten times the speed of sound.
