The US Air Force has detonated the warhead on its Air-Launched Rapid Response Weapon (ARRW) hypersonic missile for the first time during a test.
The AGM-183 Air-Launched Rapid Response Weapon (ARRW) was successfully detonated by the 780th Test Squadron, which is based at US Air Force Base Eglin in Florida, the US Air Force said in a statement.
ARRW (pronounced “arrow”) is an air-to-ground prototype missile that is launched from the B-52 Stratofortress aircraft. The missile is based on the Defense Advanced Research Projects Agency’s Tactical Boost Glide system, work on which began in 2015.
ARRW is a hypersonic glide vehicle, meaning it is launched from a rocket and glides to its target at hypersonic speeds, as opposed to hypersonic cruise missiles, which are powered by air-breathing engines, also known as scramjets.
AARW will be capable of travelling at average speeds of between Mach 6.5 and Mach 8 at a range of approximately 1,000 miles (1,600km).
The prototype missile successfully completed a series of captive carry test flights using a B-52 aircraft between June 2019 and August 2020. However, ARRW’s first free-flight test failed in April 2021, at Point Mugu Sea Range, off the coast of Southern California.
The recent test was the first time engineers have tested the AARW hypersonic missile’s warhead to collect data on its lethality.
According to the test’s manager, David Spiker from the 780th Test Squadron, the nature and shape of the warhead required “a lot of firsts for everyone involved”, including a “new and unorthodox design and construction for the test arena, the test procedures and equipment, the warhead’s fragmentation data collecting and the post-test data processing to ensure the warhead’s effects have been accurately characterized”.
The 780th Test Squadron successfully designed and conducted the test to ensure the customer’s data requirements were met using new and improved test tools, technologies, and techniques.
