Fox News reports the U.S. Air Force announced this week that it tested a hypersonic missile over the Pacific Ocean.

The military reportedly conducted the weapons test via a B-52H Stratofortress taking off from a base in Guam.

“This test launched a full prototype operational hypersonic missile and focused on the ARRW’s end-to-end performance,” an Air Force spokesperson said in a statement, according to Axios. “The Air Force gained valuable insights into the capabilities of this new, cutting-edge technology.”

Communications about the weapon test’s objective remain somewhat vague, stating that the test provided “valuable, unique data” to assist “a range of hypersonic programs.”

“While we won’t discuss specific test objectives, this test acquired valuable, unique data and was intended to further a range of hypersonic programs,” the Air Force spokesman’s statement continues. “We also validated and improved our test and evaluation capabilities for continued development of advanced hypersonic systems.”

An Air Force spokesperson told the outlet The War Zone that the test was conducted at the Andersen Air Force Base, one of three military bases in Guam.

“A B-52H Stratofortress conducted a test of the All-Up-Round AGM-183A Air-launched Rapid Response Weapon,” the spokesperson said in the statement. “This test launched a full prototype operational hypersonic missile and focused on the ARRW’s end-to-end performance. The test took place at the Reagan Test Site with the B-52 taking off from Andersen Air Force Base, Guam.

The announcement comes amid an international scramble for hypersonic weapons – China, Russia, and North Korea have all claimed to make advances in developing the technology.
