By: Sebastian Sprenger COLOGNE, Germany — German tank-maker Krauss-Maffei Wegmann is developing a tactical bridge-launching capability for its Boxer vehicle that the company hopes to sell to its growing customer base. Executives still consider the module an internal prototype, with more testing planned in the coming months. But the premise of a bridge-launching capability in forces lighter than the heavy, tracked vehicles mostly used for that job today could garner interest, they said. The German military, Lithuania, the Netherlands, the U.K. and Australia are current or soon-to-be operators of Boxer fleets. The vehicles were developed in a joint venture with Germany's Rheinmetall. The rides are modular by design, consisting of base chassis that can be combined with payloads for troop transport, command and control, combat, or medical evacuation, for example. The new module will be able to deploy two types of bridges: a heavy variant that spans 14 meters and can carry 80 tons, and a longer version of 22 meters certified for 50 tons. Those weight limits are sufficient for heavy battle tanks and the slightly lighter infantry fighting vehicles, respectively. KMW officials had planned to debut the new development at the Eurosatory expo in Paris, France, last month before organizers canceled the event due to the coronavirus pandemic. The next chance to display the bridging module for would-be clients will be the U.K.-based DVD2020 conference, sponsored by the British Ministry of Defence, in November, according to the company. Modifications needed to operate the bridging module with the base version of the Boxer include a new drive output for siphoning power from the main engine to the hydraulic arms used to push the bridge from the vehicle to the ground, officials explained. https://www.defensenews.com/land/2020/07/23/germanys-kmw-pitches-bridge-launching-boxer-to-its-customer-base/

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/
