The test occurred in early July, and the agency said in a July 18 statement it expanded its understanding of the weapon\u2019s engine capability and met all of its test parameters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis most recent test allowed exploration of more of the flight and scramjet engine operating envelopes,\u201d program manager Andrew Knoedler said. \u201cDARPA demonstrations are always about learning, whether it\u2019s in the interest of feasibility or practicality, and this time we certainly got new information that will further improve performance.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Raytheon and Lockheed Martin are both developing HAWC prototypes through a joint effort between DARPA and the U.S. Air Force. Lockheed\u2019s missile had <a href=\"https:\/\/www.defensenews.com\/air\/2022\/04\/05\/pentagon-kept-hypersonic-test-quiet-amid-russia-tensions\/\" target=\"_blank\">its first test in March<\/a>, but the program has not yet confirmed a second flight. Northrop Grumman developed the engine for Raytheon\u2019s missile, while Aerojet Rocketdyne developed Lockheed\u2019s.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Raytheon\u2019s President of Air Power Paul Ferraro told C4ISRNET in a July 19 interview at the Farnborough Airshow the company\u2019s approach to HAWC development relies heavily on digital engineering and high-fidelity models to better understand its missile\u2019s response to the environment before it takes flight.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s especially important for hypersonic missiles because the extreme environments in which they operate can cause them to deform or change shape during flight, which affects their performance. Ferraro said Raytheon has advanced its modeling to the point that it can use testing history to create a more comprehensive understanding of the missile\u2019s attributes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That degree of foreknowledge about the system\u2019s performance is a paradigm shift, Ferraro said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWhat we used to do is test to learn about the design,\u201d he said. \u201cNow, we more or less test to validate our models, and that\u2019s where our real learning and design information comes from.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Having better models also means the government can shift more of its validation work into the digital environment, helping alleviate constraints on flight-test infrastructure, Ferraro said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As DARPA collects data from the early July HAWC test, the agency is making plans for the program\u2019s next phase, which it <a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/2022\/05\/09\/darpa-maturing-scramjet-powered-hypersonic-weapon-concept-through-follow-on-program\/\" target=\"_blank\">announced in its fiscal 2023 budget request<\/a>. DARPA requested $60 million for the new-start effort, called MoHAWC, to support continued technology development, pay for long-lead component procurement for four more flight-test systems and fund risk reduction for assembly, integration and ground testing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cThis most recent test allowed exploration of more of the flight and scramjet
