08/09/2020 September 8, 2020: Two variants of the Hypersonic Air-breathing Weapon Concept (HAWC) are ready to proceed to first free-flight testing within the calendar year. DARPA and the U.S. Air Force (USAF) announced successful completion of captive carry tests, as the joint Agency and Service effort seeks to develop and demonstrate critical technologies to enable an effective and affordable air-launched hypersonic cruise missile. ..HAWC performers Lockheed Martin and Raytheon Technologies have each tested advanced air vehicle configurations that promise to achieve and sustain efficient hypersonic flight. Their upcoming flight tests will focus on hydrocarbon scramjet-powered propulsion and thermal management techniques to enable prolonged hypersonic cruise, in addition to affordable system designs and manufacturing approaches. .."Completing the captive carry series of tests demonstrates both HAWC designs are ready for free flight," said Andrew "Tippy" Knoedler, HAWC program manager in DARPA's Tactical Technology Office. "These tests provide us a large measure of confidence â?" already well informed by years of simulation and wind tunnel work â?" that gives us faith the unique design path we embarked on will provide unmatched capability to U.S. forces." ..The HAWC program, since inception, has been executed as a joint program between DARPA and the USAF. In addition, DARPA is working in cooperation with military services and agencies, including the Missile Defense Agency, U.S. Navy, and National Aeronautics and Space Administration (NASA) to validate, and eventually transition key technologies. The extensive flight data collected is intended to increase the confidence in air-breathing hypersonic systems and reduce the risks to potential future acquisition programs across the U.S. government...When: 08 Sep 2020.Credit: DARPACover Images..**Editorial use only* POLITICA Europa Press/Contacto/Cover Images

EE.UU. y Japón planean crear un misil para contrarrestar armas hipersónicas

EE.UU. y Japón han decidido crear conjuntamente un nuevo tipo de misil capaz de interceptar armas hipersónicas creadas por China, Rusia y Corea del Norte y que no pueden contrarrestar con las defensas antimisiles existentes, informó The Japan News.

Con este objetivo, el primer ministro japonés, Fumio Kishida, y el presidente de estadounidense, Joe Biden, abordarán la cuestión de su desarrollo en la cumbre de EE.UU, Japón y Corea del Sur planeada para este viernes en Washington.

Cabe recordar que las armas hipersónicas vuelan a una velocidad que supera en cinco veces la velocidad del sonido y se desplazan a baja altura, lo que dificulta su interceptación con los sistemas de radar existentes.
