The United States (US) Department of Defense, along with the Australian Department of Defence and the United Kingdom (UK) Ministry of Defence, on Monday announced the signing of an agreement to enhance testing of hypersonic vehicles and accelerate implementation of related technologies, the Pentagon informed in a statement.

“Under AUKUS Pillar II, the three nations have entered the Hypersonic Flight Test and Experimentation (HyFliTE) Project Arrangement (PA) to use each other’s testing facilities and share technical information to develop, test, and evaluate hypersonic systems,” the statement adds.

"We are increasing our collective ability to develop and deliver offensive and defensive hypersonic technologies through a robust series of trilateral tests and experiments that will accelerate the development of hypersonic concepts and critical enabling technologies," said Heidi Shyu, Under Secretary of Defense for Research and Engineering.
