  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/

  Defense authorization bill delayed until after election

  By: Joe Gould WASHINGTON — A bipartisan compromise and vote on the 2021 defense policy bill isn't likely before the Nov. 3 elections, but it should come “quickly” thereafter, the House Armed Services Committee's top Republican said Wednesday. The vote would delay a decision from Congress about whether the Defense Department to rename military bases honoring Confederate leaders. It's defining issue for the $740.5 billion defense authorization bill, which includes must-pass provisions like military pay hikes, defense equipment purchase plans and strategic posturing of forces in coming years. “There are more negotiations that have to occur, and part of that negotiation is talking with the White House about the shape of that provision,” Rep. Mac Thornberry, of Texas, said at the Defense News Conference. “Is there a way to get everybody to ‘good?' Of course there is. Is it likely to happen before the election? No, it's not.” Republicans and Democrats in the House and Senate voted overwhelmingly to back language requiring the changes, though the House requires the names changed within one year and the Senate bill requires them within three years. President Donald Trump has threatened to veto the 2021 National Defense Authorization Act over the Confederate name changes among other issues. Trump has said Senate Armed Services Chairman Jim Inhofe, R-Okla., personally assured him that Congress will not force the Pentagon to change the names. That's fueled speculation that bipartisan negotiations to reconcile the bills could drag on. The summer's sustained protests over racial injustice have buoyed the provision, while Trump has argued that changing the names would dishonor troops who have served at the sites and that Confederate symbols aren't racist. “We can't cancel our whole history,” he told Fox News last month. Thornberry, who had offered a softer alternative as a House amendment, said Wednesday that both sides have political incentives not to compromise on the base renaming provision, among other issues. “I don't know how that will come out in conference, but I do think we are in a time when neither party is rewarded for compromise, and coming together and getting things done,” he said. “On the other hand, I think we should be able to get a conference report pretty quickly after the election.” https://www.defensenews.com/congress/2020/09/09/no-defense-authorization-bill-before-election-says-thornberry/
