Russia tests S-400 missiles in Crimea amid tensions with Ukraine

A day after NATO and Ukraine began Black Sea military exercises, Moscow announces it has tested Crimean air defence systems.

Russia has reportedly tested the readiness of its air defence systems in Crimea, an apparent show of force as Ukraine and NATO countries hold military drills in the Black Sea as part of their Sea Breeze 2021 exercise. Russia deployed about 20 warplanes and helicopters, including Su-24M bombers, as well as S-400 and Pantsir surface-to-air missile systems in the tests, Interfax reported on Tuesday, citing Russia’s Black Sea fleet. It was not clear when the tests took place.
