  Northrop to build 3D-printed scramjet engine for Raytheon hypersonic weapon

  By: Valerie Insinna LE BOURGET, France — Raytheon has partnered with Northrop Grumman on its air-breathing hypersonic weapon, which will be powered by a Northrop-made scramjet made entirely of 3D-printed parts, the company announced Tuesday. Raytheon and Northrop's weapon is one of the competitors in the U.S. Defense Advanced Research Projects Agency's HAWC project, short for Hypersonic Air-Breathing Weapon Concept. The companies' offering — which comprises Northrop's scramjet engine and Raytheon's air vehicle — is ready to make its first flight, said Tom Bussing, vice president of Raytheon's advanced missile system segment. “We have a flight test planned for the near future where we will begin flying this particular class of weapon system,” he said during a briefing at Paris Air Show. While the exact schedule is classified, Bussing noted that the companies have already conducted “significant” ground tests “The combustor, everything that we do now is done by additive manufacturing, so its driving affordability into the hypersonic boost missile's scramjet engine. We are also looking at ways to reduce the weight so we can have more fuel, more payload,” he said. The entirety of Northrop's scramjet is 3D printed using advanced materials, said John Wilcox, the company's vice president of advanced programs and technology. “There gets to be points where you have to weld additive manufactured parts, but right now even the full combustor [is printed],” he said. “We think we're the first to ever 3D print a full combuster for an air-breathing scramjet engine. That's what's going to drive the affordability for air-breathing scramjet missiles.” According to Raytheon, scramjet engines use high vehicle speeds to then compress air moving into its inlets before combusting it. The process allows a vehicle to maintain hypersonic speeds — more than five times the speed of sound — over longer periods of time. The Raytheon-Northrop team is competing against Lockheed Martin for the final HAWC contact. https://www.defensenews.com/digital-show-dailies/paris-air-show/2019/06/18/northrop-to-build-3d-printed-scramjet-engine-for-raytheon-hypersonic-weapon/

  New Model Standardizes Measurement Of Cybersecurity In Critical DoD Assets

  ARLINGTON, Va., Aug. 13, 2019 /PRNewswire/ -- Cyber experts from Lockheed Martin [NYSE: LMT] developed and piloted a first-of-its-kind model that standardizes how to measure the cyber resiliency maturity of a weapon, mission, and/or training system anywhere in its lifecycle – the Cyber Resiliency Level™ model (CRL®). The U.S. government defines "cyber resiliency" as the ability to anticipate, withstand, recover from, and adapt to changing conditions in order to maintain the functions necessary for mission effective capability. Until now, the aerospace and defense industry lacked a simple, common method to discuss cyber resiliency of a military system. "Today's software-based military systems and a global supply chain make securing military systems a complex problem to solve," said Jim Keffer, director of Cyber, Lockheed Martin Government Affairs. "With the CRL, we can now leverage existing risk management frameworks to effectively measure and communicate resiliency across six categories we know are important to our customers. The release of this model builds on Lockheed Martin's enduring commitment to mission assurance and will ultimately help the warfighter operate in cyber-contested environments." To use the model, engineers work with U.S. and allied military program stakeholders to conduct a series of risk and engineering assessments. The process provides increased visibility into the current state of risk and produces a customized, risk-mitigation roadmap that shows how to increase a system's CRL to a more desirable level. "In an era of scarce resources, the CRL model can help stakeholders make informed decisions and prioritize cyber spending on the most impactful solutions," said Keffer. To date, Lockheed Martin has used model-based assessments on several of its own systems across multiple domains and plans to conduct at least 10 CRL assessments by the end of 2019.
