  Saab prepares GlobalEye bid for South Korea

  by Jon Grevatt Saab has reaffirmed its intention to offer its GlobalEye platform for South Korea's recently announced programme to acquire additional airborne early warning and control (AEW&C) aircraft for the Republic of Korea Air Force (RoKAF). Saab told Janes that it expects the procurement to feature an initial two aircraft acquired through either an open tender or a direct acquisition. South Korea's Defense Acquisition Program Administration (DAPA) is expected to confirm the procurement method later this year. A Saab spokesperson said that the company's offer will also include “both technology and collaboration projects” that match South Korea's future aerospace requirements and involve “multiple stakeholders from the military, government, industry, and other partners”. While detail on these projects will be expanded as the programme enters future phases, the spokesperson said Saab has already developed “clear principles and ideas for collaboration” as well as highlighted its own capabilities to local stakeholders, and “gathered information on Korean industry”. The spokesperson said, “Korea is a country with a highly skilled and developed industry opening several interesting areas for co-operation which we hope to explore further in the coming stages of the programme.” Although not confirmed by the company, this is likely to draw on Saab's existing industry ties in the country, which include strong links with LIG Nex1, one of South Korea's leading military electronics and missile manufacturers. Saab and LIG Nex1 have previously collaborated on supplying the Swedish group's Arthur Weapon Locating System to the Republic of Korea Armed Forces and on developing radar technologies. https://www.janes.com/defence-news/news-detail/saab-prepares-globaleye-bid-for-south-korea

  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/
