“The crews focused on the fundamentals of hypersonics, operational and logistics considerations, and in-depth tactical discussions,” the service added.

During a similarly-described hypersonic weapons training event at Edwards Air Force Base in California in 2023, another live ARRW bearing the serial number AR-AUR-004, along with a glimpse of a secretive air-breathing hypersonic cruise missile under development by the Air Force, were also observed in pictures.

Meanwhile, the latest appearance of the missile at Guam raises eyebrows, given the US Air Force’s earlier announcement of its intention to discontinue the troubled AGM-183 Air-launched Rapid Response Weapon (ARRW) hypersonic weapon program.

The decision to abandon the AGM-183 ARRW stems from its multiple failures, prompting the Air Force to forego further procurement of the ARRW post-prototyping program and instead concentrate on the Hypersonic Attack Cruise Missile.

Presence Of US Hypersonic Missile Near China

The release of these photos is significant, given Guam’s strategic location in the Indo-Pacific region. Some reports suggest that this marks the first instance of a US hypersonic weapon being observed in such proximity to China.

The purpose behind the AGM-183’s presence in Guam remains a mystery, especially considering the Air Force’s prior announcement of its intention to discontinue the ARRW program.

Currently, no definitive signs indicate the Air Force’s intentions to conduct a live-fire ARRW test from Guam, although the possibility remains under consideration.

If such a test were to occur, it would serve not only as a display of power in the Pacific area but also communicate strategic signals to potential rivals, notably China and Russia.

Initially slated to be the United States’ first operational hypersonic weapon, the trajectory of the ARRW has become increasingly uncertain over time, with years of flight testing producing mixed results.

Despite the program’s interruption, the Air Force asserts that completing the test flights will provide invaluable learning and test data for future hypersonic endeavors.

ARRW consists of an unpowered hypersonic boost-glide vehicle and a large rocket booster, accelerating the missile to optimum speed and altitude before releasing the glide vehicle. It glides at hypersonic speeds along a shallow path, offering maneuverability.

While the US lags behind China in hypersonic technology, the US government is actively striving to rapidly deploy operational hypersonic systems.

Between April 2021 and May 2022, the Air Force initiated the initial five live-fire tests of AGM-183. These tests showcased a spectrum of outcomes, ranging from two failures to two complete successes and one partial success.

On December 9, 2022, the successful execution of the first comprehensive end-to-end test took place. Since March 2023, the momentum of live-fire testing for ARRW has persisted, witnessing at least three additional end-to-end tests.

The initial test in March 2023 concluded in failure, and the subsequent launches in August and October 2023 saw few details being released.

Despite previous plans to terminate the program, the ARRW program, in Fiscal Year 2024, is slated to undertake further testing initiatives.

These flights aim to validate the launch conditions envelope and assess the flight characteristics of the ARRW. Specifically, AUR test flights will target land-based objectives.
