    Who Will Build 651 Parachuting Trucks For The Army?

    By SYDNEY J. FREEDBERG JR. WASHINGTON: Three very different teams are vying to build the Army's Infantry Squad Vehicle, a truck tough enough to parachute out of an airplane and then drive away cross-country with nine heavily armed infantrymen. By Nov. 13th, each team owes the Army two vehicles for testing, with the winner getting a contract for 651 ISVs next year. Let's meet the players. The Oshkosh-Flyer team is the closest thing to an incumbent in the competition. The Army had earlier picked the Flyer-72 as an interim air-droppable transport, the A-GMV, and Flyer is offering an upgraded version for the follow-on program, ISV. Actual mass production will be done by Oshkosh, which makes a host of Army trucks — most prominently, the beefed-up successor to the Humvee, the Joint Light Tactical Vehicle (JLTV), which the Army and Marine Corps plan to buy over 50,000 of in the coming decades. What's more, Oshkosh plans to build the 5,000-pound ISV on the same assembly line as all its other vehicles, from the 14,000-lb JLTV to 10-ton FMTV dump trucks. (The earlier version of the Flyer-72 was mass-produced by General Dynamics). The ISV will be the lightest vehicle on the Oshkosh line, VP George Mansfield told me, but the company is confident it can build the air-droppable trucks more affordably than Flyer could — and at least as well. In fact, Mansfield said, he expects the Oshkosh-built version to be more reliable. That's in part because of Oshkosh's manufacturing expertise — it won the JLTV contract in large part because its offering broke down less than half as often as uparmored Humvees — and in part because of Flyer's extensive field experience with the earlier versions built for the Army and Special Operation Command. As a team, Mansfield told me, “we've learned a lot about reliability, we've learned a lot about life-cycle cost, that now we can take here at Oshkosh with our extensive knowledge of all the other product lines we sell to the Army.” Polaris and SAIC both have plenty of defense experience. Polaris's DAGOR did lose the earlier A-GMV contest to Flyer, but numerous DAGOR variants are in widespread service with Special Operations Command, the 82nd Airborne Division (shown in the video above), Canada, and other foreign customers the company can't disclose. “The DAGOR is already certified” — by the Army itself — “for all of the transport requirements that the Army is looking for, whether that's internal air transport, sling-load transport, or air-drop,” Polaris VP Jed Leonard told me. And each of those prior customers required tweaks to the platform or special mission equipment — heavy weapons, sensors, radios — that the DAGOR could easily accommodate. Integrating such high-tech kit is SAIC's core competency. While not a manufacturer itself, SAIC has done decades of integration work for the military, most extensively on the MRAP program, fitting other companies' vehicles with the sophisticated electronics that turn a truck into a weapons system. It also provides extensive maintenance and other support worldwide. The two companies have worked together on and off, on small projects, for years, as various customers bought Polaris vehicles and then asked SAIC to equip them for specific military missions. But the current partnership is a big step up for both. The odd man out is GM Defense, which giant General Motors created — in a sense, re-created — not quite two years ago after selling off most of its defense programs back in 2003. GM Defense president David Albritton just came aboard a year ago and has spent much of his time working with “Mother GM” on potential joint projects and spin-offs, from self-driving car technology to hydrogen fuel cells, he told me in an interview. “I'm not reporting any revenues at this point,” he said, although GM Defense does already have some contracts he can't disclose. GM's offering is the only contender without a prior track record in the military. But their ISV is derived from the Chevrolet Colorado, of which US customers have bought more than 100,000 a year of since 2016, giving GM staggering efficiencies of scale no competitor can match. Specifically, the GM ISV a beefed-up, militarized version of the Colorado's offroad racing variant, the ZR2, with which it shares 70 percent of the same parts — parts that are available from Chevy dealers worldwide. GM builds over 10,000 ZR2s a year: a rounding error for General Motors but a megaprogram for the Army. GM's scale advantage is not just in production and parts. It's also in engineering. The company spends over $7 billion a year on R&D, Albritton told me, and its ISV offering includes advanced suspension systems like jounce shocks and dynamic spooling. GM's challenge is overcoming its inexperience in the defense sector — especially, proving it can integrate military electronics onto its civilian-derived vehicle. LRPF: Long-Range Precision Fires. NGCV: Next-Generation Combat Vehicle. FVL: Future Vertical Lift. AMD: Air & Missile Defense. SL: Soldier Lethality. SOURCE: US Army. (Click to expand) The Big Picture Overall, ISV is an especially interesting competition because none of the contenders is a classic defense prime: Oshkosh and Polaris both have lots of civilian customers alongside their extensive military business. Flyer is a subunit of a modest aerospace and defense components-builder called Marvin Group. SAIC is a systems engineering and service firm rather than a traditional Original Equipment Manufacturer. And GM of course is one of the biggest civilian manufacturers in the country. “We make upwards of nine million cars a year,” Albritton told me, each put together out of roughly 30,000 different parts. Compare and contrast the Army's Optionally Manned Fighting Vehicle program, which is de facto down to a single competitor — defense industry stalwart General Dynamics (which bought GM's previous defense business back in 2003). ISV shows the kind of variety that the Army wants to encourage and needs to infuse innovation and competition into its programs. Yes, at 651 trucks — at least, in the initial 2020 contract — this is a modest program in both size and technological ambition. It's easily overshadowed by the hypersonic missiles, high-speed aircraft, and robotic tanks of the Army's Big Six priorities. By contrast, for the predecessor competition (the one Flyer won) back in 2015, we ran eight stories in three months because there was so little else the cash-strapped and acquisition challenged Army was buying at the time. But the Infantry Squad Vehicle is still an important piece of the larger Army puzzle. The Army's infantry brigades — especially its 82nd Airborne parachutists — are its most strategically deployable units, easily packed into aircraft and flown around the world overnight, while heavy armored forces cram two tanks into one C-17 or, more often, go by ship. But once the infantry arrives, it moves on foot. (Although we bet everyone in the 82nd remembers being called a “speed bump” in this Defense Science Board study.) The idea of ISV is a troop transport light enough to be air-dropped or, more often, delivered by helicopter. That way, the troops can land a long distance from their target — specifically, far enough their transport planes or helicopters aren't shot down by anti-aircraft missiles — and then advance quickly overnight before attacking on foot at dawn. We expect to see all three competing vehicles on the show floor at the Association of the US Army megaconference next week. https://breakingdefense.com/2019/10/who-will-build-651-of-the-armys-parachuting-truck/

    Lockheed Martin Wins $933 Million U.S./Saudi THAAD Mod

    Lee Hudson The U.S. Air Force has upgraded an existing deficiency for the KC-46A Pegasus fuel system to Category 1. The service's program office first identified “excessive fuel leaks” in July after an air refueling test. The Air Force and Boeing are working together to determine the root cause and implement corrective actions. A Category 1 deficiency means the government has identified a risk that jeopardizes lives or critical assets. “The KC-46 Program Office continues to monitor the entire KC-46 fleet and is enhancing acceptance testing of the fuel system to identify potential leaks at the factory where they can be repaired prior to delivery,” according to an Air Force statement. Boeing is contractually obligated to rectify this deficiency at no additional cost to the Air Force. “We are disappointed to learn of this development and are already implementing assembly and installation improvements to correct the issue,” Boeing spokesman Larry Chambers said in a statement to Aerospace DAILY. “We have repaired several of the airplanes and will continue to implement repairs as needed. Boeing is working with urgency to address this issue.” The Air Force discovered several required fuel-system repairs, Chambers said. The fuel system is equipped with redundant protection for fuel containment. “In some cases with this issue, aircraft maintenance crews are finding fuel between the primary and secondary fuel barriers within the system,” Chambers said. The KC-46A program still faces other unresolved Category 1 deficiencies that involve the Remote Vision System (RVS) and the boom telescope actuator. The problem with the RVS is what the Air Force calls a “rubber sheet” effect that distorts the image on the visual display used by the boom operator during refueling operations. The actuator on the boom needs to be more sensitive to smaller receiver aircraft, such as A-10s and F-16s. Boeing has agreed to pay for the RVS design fix, while the Air Force will finance the design change to the actuator. “There's profound problems with the system,” Air Force Chief of Staff Gen. David Goldfein said March 3 during a Senate Armed Services Committee hearing. The service is certifying the aircraft to conduct airlift and medical evacuation missions. The plan is for the Air Force to employ the KC-46 in those roles while a long-term fix is being developed, Goldfein said. Goldfein told new Boeing CEO Dave Calhoun to focus on the KC-46 program, even as it is fixing the 737 MAX. Calhoun said the KC-46 is his top military priority. “I have seen a change in the behavior of that company since he took over, and so that's why we're more confident sitting here today that we have a serious fix on the table,” Goldfein said. “We're in final negotiations, so we can't go into any more detail than that. But I will say that it's looking better today than it was even six months ago.” https://aviationweek.com/defense-space/aircraft-propulsion/usaf-announces-new-major-deficiency-kc-46

    Les 4 projets militaires et spatiaux de Boeing à suivre en 2019

    RÉMI AMALVY Drone MQ-25, Boeing MH-139 ou T-X, programme Starliner... Boeing dresse le bilan de son actualité militaire et spatiale de 2018 par le biais de deux courtes vidéos. L'occasion pour l'Usine Nouvelle de revenir plus en détails sur les principaux projets du géant aéronautique américain. 1 - Boeing MH-139 : A destination de l'US Air Force, les Boeing MH-139 permettront à l'armée américaine de remplacer ses célèbres UH-1N "Huey", en service depuis plus de 40 ans. Les petits nouveaux serviront pour la protection des bases hébergeant des missiles balistiques intercontinentaux ainsi que pour le transports des militaires et des membres du gouvernement américain. Les premières livraisons sont prévues pour 2021. 2 - Boeing MQ-25 : En début d'année, Boeing a présenté un prototype de son nouveau drone, le MQ-25. Cet appareil sans pilote aura pour mission de ravitailler en carburant et en plein vol les différents engins Boeing de l'armée américaine, comme les F/A-18 Super Hornet, les EA-18G Growler et les Lockheed Martin F-35C fighters. Le drone est désormais prêt, et devrait être mis en service pour l'US Navy "dès que possible". 3 - Boeing T-X : Boeing fournit également à l'armée américaine son nouveau système de formation pour pilotes. Constitué d'un modèle spécial d'avion, d'une base au sol et de divers supports, il devrait permettre à l'US Air Force d'entraîner au mieux ses équipes. Un vol test avait déjà eu lieu en mai dernier. Autre source de fierté outre-Atlantique, 90% de l'appareil T-X est conçu aux États-Unis, et le programme devrait fournir plus de 17 000 emplois dans 34 Etats. 4 - Boeing Starliner : 2018 aura été une année bien remplie pour les équipes du programme spatial de Boeing. Elles développent leur nouveau véhicule spatial CST-100 Starliner en collaboration avec la NASA, pour le transports des équipages vers la station spatiale internationale. Le Starliner a été conçu pour accueillir jusqu'à sept passagers pour des missions en orbite basse. Dans le cadre des prochains voyages jusqu'à l'ISS, quatre membres de l'agence américaine accompagnés de matériels et de données scientifiques feront le trajet. Chaque Starliner est utilisable jusqu'à dix fois, avec une période de six mois entre chaque voyage. Il est également équipé du wi-fi et d'une interface tactile. Pas moins de 3 Starliners sont développés actuellement au sein du célèbre Kennedy Space Center de la NASA, en Floride. En avril dernier, Boeing a publié sur Youtube la vidéo à 360° ci-dessous. Elle permet de voir un court instant ce qu'il se passe entre les murs de l'usine, pour la conception de l'une des navettes. Enfin, pour les plus passionnés, Boeing propose une interview (en anglais) de Chris Ferguson. Ancien capitaine de la Navy, il est surtout connu pour avoir été pilote et commandant de 3 missions spatiales de la NASA, STS-115 en 2006, STS-126 en 2008 et STS-135 en 2011. Il travaille depuis avec Boeing dans le cadre du programme Starliner, et devrait être le premier astronaute que la société enverra dans l'espace. https://www.usinenouvelle.com/article/video-les-4-projets-militaires-et-spatiaux-de-boeing-a-suivre-en-2019.N787934
