As we enter the 2020s, China, Russia and the United States are spending billions to develop hypersonic weapons in a bid to outpace ever-improving missile defenses.
While strategic-range cruise or ballistic missile strikes may be detected between 15 minutes to an hour before impact, hypersonic weapons capable of exceeding five times the speed of sound threaten to decrease that margin to just a few minutes. Such a fast tempo of destruction could destabilize the current balance of power by making first strikes more effective and unpredictable.
China and Russia have taken a lead in this new arms race. In October, China paraded launchers for land-attack DF-17 and anti-ship DF-100 hypersonic missiles. Meanwhile, Russia supposedly is deploying nuclear-capable hypersonic Kinzhal air-launched missiles and Avangard glide vehicles released by RS-28 intercontinental-range missiles.
