Russia equipping its most potent attack submarines with hypersonic missiles, official says

Russia is outfitting its new nuclear submarines with hypersonic Zircon missiles, the head of the country’s largest shipbuilder said in an interview published Monday. ... “In a sense, the challenge for NATO remains the same,” Sidharth Kaushal, a research fellow at the Royal United Services Institute, said in response to the news. That challenge is countering Russia’s nuclear-powered attack submarines and cruise missile submarines, he said. The speed of the new missiles and the relative quietness of the launch platform will complicate NATO’s efforts, Kaushal added.
