WASHINGTON — In March 2018, Russian President Vladimir Putin touted his nation's budding arsenal by unveiling a slew of new hypersonic weapons.

Of the six new weapons Putin unveiled, CNBC learned that two of them, a hypersonic glide vehicle and an air-launched cruise missile, will be ready for war by 2020.

What's more, China announced in 2018 that it had conducted the first successful testing of a hypersonic aircraft, a feat the United States has yet to accomplish.

The paces made by Russia and China have triggered a three-way arms race in developing this new breed of weapon.

The U.S. does not have a defense against hypersonic weapons, which can travel at least five times the speed of sound, or a little more than a mile per second. Combined with blistering speed, maneuverability and long-range flight, these weapons are difficult to track, target and defeat.
