The US Department of Defense (the Pentagon) said that the three tests were successful, and were conducted on weapons components, as they demonstrated advanced hypersonic technologies, capabilities and initial systems in a realistic operating environment.
Supersonic missiles are advanced weapons that can move at more than five times the speed of sound, or 3,853 miles per hour. Their phenomenal speed poses a challenge to current missile warning systems.
The tests were conducted on the same day that US President Joe Biden said he was concerned about Chinese hypersonic weapons.
The Ministry of Defense said in a statement that the Sandia National Laboratory conducted the tests from the "Wallops" flight facility of the US Aeronautics and Space Administration (NASA) in Virginia, which will help "guid the development of the (conventional rapid strike) program. Navy and the Army's Long-Range Hypersonic Weapon" program aimed at developing supersonic offensive weapons.
The Navy and the Army will test-fire a conventional supersonic missile in the 2022 fiscal year, which began on October 1, 2021.
Hypersonic weapons travel in the upper atmosphere at more than five times the speed of sound, or about 6,200 kilometers per hour.
