The US Air Force (USAF) requested just shy of USD517 million to continue development of Raytheon's Hypersonic Attack Cruise Missile (HACM) hypersonic air-breathing missile in its fiscal year (FY) 2025 presidential budget request, but zeroed out the procurement of the Lockheed Martin AGM-183 Air-launched Rapid Response Weapon (ARRW) hypersonic boost-glide weapon.
The FY 2025 funding request is a change from that of FY 2024, which requested USD350 million for HACM and USD150 million for ARRW.
ARRW was for years considered the frontrunner in the US's race to field an air-launched hypersonic weapon, but the system has seen mixed results in all-up round flight-testing, notching both successes and failures. The final all-up round test is thought to be upcoming, following the USAF's publication of a photograph depicting the munition in Guam, hanging from the wing of its B-52 launch platform.
Nevertheless, USAF officials have repeatedly stated their intent to assess ARRW test results before making a production decision, a process that remains ongoing.
“The [US] Air Force remains committed to fully analysing and understanding all test data gathered while conducting the ARRW rapid prototyping test series,” said a USAF spokesperson on 10 March. “This data will inform subsequent development and fielding decisions with ARRW.”
