The Russian Ministry of Defense reported on Monday that one of its warships, the Admiral Gorshkov, has conducted the successful test-fire of a high-tech missile, ahead of the rockets being rolled out to submarines and naval ships.

In a statement issued by Moscow, military chiefs said that “the Zircon missile successfully struck the target in the White Sea with a direct hit at a distance of over 350 kilometers. The test confirmed the tactical and technical performance of the missile, and its flight speed was around Mach 7.” This means that the projectile flew at hypersonic velocity, seven times faster than the speed of sound.

There are now plans to kit out a range of other naval vessels, including both submarines and surface ships, with the Zircon system. In April, Russian President Vladimir Putin said that next-generation “hypersonic and laser” weapons were an essential part of the country’s future arsenal to deter aggression from overseas. “We have patience, self-confidence, and righteousness on our side,” Putin added. “I hope no one will think of crossing red lines in their relations with Russia. Where that line sits is ours to determine.”
