In what appears to be a world-first, Russia on Monday successfully launched a hypersonic cruise missile from a submarine. Russia's defense ministry subsequently published video of the nighttime launch from the far northern Barents Sea, saying the test was successful and that the missile hit its target.
"The test firing of the Tsirkon missile from a nuclear submarine was deemed successful," the ministry stated. And Reuters detailed that "Low-quality video footage released by the ministry showed the missile shooting upwards from a submarine, its glare lighting up the night sky and illuminating the water's surface."
