The US Department of Defense had an unsuccessful test related to the development of its hypersonic weapon after a missile booster failed to work, a Pentagon spokesperson told, APA reports citing Sputnik.
"On Oct. 21, the Department of Defense conducted a data collection experiment from the Pacific Spaceport Complex-Alaska, Kodiak, AK [Alaska], to inform the department’s hypersonic technology development," the spokesperson said in a statement on Thursday night.
"The test did not occur as planned due to a failure of the booster stack."
The spokesperson said the booster stack used in the test was not part of the hypersonic program and is not related to the Navy-designed Common Hypersonic Glide Body, which the Defense Department successfully tested on March 20, 2020.
