AGM-183 ARRW
Overview
AGM-183 ARRW (Air-Launched Rapid Response Weapon) is an air-launched hypersonic missile developed by the U.S. Air Force together with Lockheed Martin. It was intended to rapidly strike key enemy facilities at speeds above Mach 5 using a boost-glide approach, and development was pursued from the late 2010s. It experienced repeated successes and failures across multiple tests, and after 2024 its status was adjusted amid changes in the U.S. Air Force's hypersonic weapons acquisition strategy.
Key Details
Development Background
From the mid-2010s, the United States sought to secure rapid strike capabilities in response to Chinese and Russian hypersonic weapons development. ARRW, as the name "rapid response weapon" suggests, was conceived as a concept to eliminate high-value enemy targets early in a conflict in a short time. In particular, it aimed to strengthen deterrence in the Indo-Pacific region, and sought to provide faster response times and greater survivability than existing conventional missiles.
Technical Characteristics
ARRW consists of a solid rocket booster and a hypersonic glide vehicle. After the booster lifts the missile to altitude, the glide vehicle separates and glides through the upper atmosphere, maneuvering at speeds above Mach 5. Its range is estimated at about 1,600 km or more, and it can be launched from B-52H bombers or F-15E fighters, among others. Its precision guidance and terminal maneuvering capability give it the advantage of being able to evade enemy air defenses. This is a representative example of a boost-glide system, distinct from cruise-type hypersonic missiles (HACM) that use scramjet engines.
Development and Testing Process
After Lockheed Martin won the development contract in 2018, multiple tests were conducted across 2021 and 2022. In December 2022, it achieved success in the first all-up round test, demonstrating its potential. However, a failure occurred in the March 2023 test, increasing uncertainty about the program. In its FY2024 budget request, the U.S. Air Force significantly removed ARRW's production budget and retained only some research, development, test, and evaluation funding.
Significance and Limitations
ARRW is one of the first air-launched hypersonic weapons developed by the United States and contributed to accumulating related technology and test infrastructure. However, due to high unit cost, complex technology, and repeated test failures, it did not reach operational deployment. It also fell behind in strategic priority with the rise of alternative programs such as HACM, which offers more flexible employment.
Latest Trends
Since 2024, the U.S. Air Force has effectively halted further acquisition of ARRW and is focusing on alternatives such as the Hypersonic Attack Cruise Missile (HACM). ARRW accumulated data through multiple flight tests up to late 2023, but with the production plan canceled in the 2024 budget proposal, the program effectively entered a wind-down process. Nevertheless, some test infrastructure and technology are being devoted to the development of next-generation hypersonic weapons. As of 2025, the United States is pursuing various hypersonic programs in parallel to respond to Chinese and Russian hypersonic threats, and ARRW is evaluated as a case of "technology demonstration." It is also having an indirect influence on discussions of hypersonic technology cooperation with allies, including South Korea.
