Explanation

Russia said Monday it had carried out another successful test of its Zircon hypersonic cruise missile, as world powers race to develop the advanced weaponry. Russia, the United States, France and China have all been experimenting with so-called hypersonic glide vehicles — defined as reaching speeds of at least Mach 5. As part of “the completion of tests” of Russia’s hypersonic missile weapons, the Admiral Gorshkov warship launched a Zircon missile at a target in the Barents Sea at a range of 400 kilometers, the defense ministry said.
