US Air Force Launches First Operational Hypersonic Missile

The United States Air Force (USAF) has successfully tested its first prototype hypersonic missile. Space.com reports: The service's new AGM-183A Air-launched Rapid Response Weapon, or ARRW ("Arrow") is expected to be the United States military's first hypersonic weapon to reach operational status. The exact speed of the AGM-183A isn't known, although the Lockheed Martin-designed weapon is said to be based on previous test vehicles built by DARPA that have an alleged maximum speed of Mach 20, or 15,000 mph (24,000 kph). The successful ARRW test was conducted on Friday (Dec. 9) in a training range off the coast of California, according to a USAF statement released Monday (Dec. 12). "This test was the first launch of a full prototype operational missile," officials wrote in the statement. "Following the ARRW's separation from the aircraft, it reached hypersonic speeds greater than five times the speed of sound, completed its flight path and detonated in the terminal area. Indications show that all objectives were met." According to the U.S. Air Force, the missile is designed to "hold fixed, high-value, time-sensitive targets at risk in contested environments," meaning it will be used to target pre-determined assets on the ground such as fixed missile sites, radar stations, air defense installations, infrastructure facilities or even adversary headquarters buildings -- basically anything important in a battlefield environment that can't be moved and needs to be destroyed quickly. [...] Now that the ARRW has successfully flown, it's likely the service could reevaluate its plans to scrap planned purchases of the AGM-183A. The AGM-183A is what is known as a boost-glide vehicle, which refers to warheads or projectiles that glide toward their targets after being lofted by a rocket booster.
