Russia is the world’s leader in hyper-sonic weapons, fielding the only existing weapons in active army use, such as the Avangard Hypersonic Glide Vehicle, The Kinzhal Aero-Balistic hypersonic missile, and the Zircon submarine launched missile.
The US is expected to field such weapons in 7 – 10 years.
Here, a test on defense against incoming hyper-sonic weapons is being perfected as well.
