  General Dynamics Griffin Takes Lead To Replace M2 Bradley

  By SYDNEY J. FREEDBERG JR. BAE System's CV90 Mark IV is the latest upgrade of a 25-year-old vehicle widely used in Europe; the Rheinmetall-Raytheon Lynx is an all-new design, although individual components have a good track record; but the General Dynamics Griffin III is in the middle, combining a new gun and new electronics with the time-tested chassis from the European ASCOD family. AUSA: General Dynamics looks like the early favorite to replace the Army's 1980s-vintage M2 Bradley troop carrier. That's my personal assessment after talking at length to officers and contractors at last week's Association of the US Army conference, where months of uncertainty finally gave way to some real clarity about both what the Army wants and what industry can offer. In brief, GD's Griffin III demonstrator seems to hit the sweet spot between innovative and proven technologies that the Army wants to start fielding a Next Generation Combat Vehicle (NGCV) as soon as 2026. Of the three vehicles on display at AUSA, BAE System's CV90 Mark IV is the latest upgrade of a 25-year-old vehicle widely used in Europe; the Rheinmetall-Raytheon Lynx is an all-new design, although individual components have a good track record; but the General Dynamics Griffin III is in the middle, combining a new gun and new electronics with the time-tested chassis from the European ASCOD family. The competitors do have a lot in common. All offer tracked vehicles with diesel engines — even BAE, which once touted its hybrid-electric drives as a key selling point. All three boast open-architecture electronics to ease future upgrades, an integrated Active Protection System to shoot down incoming anti-tank warheads, modular armor that can be layered on or stripped down depending on the mission, and a turret capable of mounting a 50 mm gun, the Army's preferred caliber. Only the Griffin actually has a 50mm installed right now, however. The others currently have 35mm cannon. It's also the only vehicle that can point its gun almost straight up, at an 85 degree angle, to hit rooftop targets in urban combat, something the Army has worried about extensively. Details like this suggest that General Dynamics has been listening more closely to the Army than its competitors. In fact, even where the Griffin III underperforms its competitors, most notably by carrying fewer infantry, it does so in areas where the Army is willing to make tradeoffs. The End of the Beginning Now, it's still early in the NGCV race. While we only saw three contenders on the floor at AUSA, it's still entirely possible a fourth player could jump in. My money's on the team of SAIC and Singapore-based STK, which is already offering a modified Singaporean army vehicle for the US Army's Mobile Protected Firepower (MPF) light tank. The other MPF competitors are BAE, with an update of the Armored Gun Systemcancelled in 1996, and GD, offering a version of the Griffin. By November, the Army will award two of the three companies contracts to build prototypes. If either GD or the SAIC-ST team wins, they'll have at least a slight advantage for NGCV, since buying related vehicles for both roles will simplify training, maintenance, and supply. (BAE's AGS is totally unrelated to its CV90, so an MPF win wouldn't help it on NGCV). By contrast to MPF, the competition for NGCV is only at the end of the beginning, not the beginning of the end. The Army's still refining its requirements, in part based on discussions with industry at AUSA. What's the timeline? Col. James Schirmer, the program manager, said at the conference that “we are within weeks of having that requirement finalized.” Brig. Gen. Richard Ross Coffman, the Army's director of armored vehicle modernization, said a formal Request For Proposal (RFP) based on those requirements will come out no later than January. So there'll be time for the competitors to revise their NGCV designs before submitting them. Even after that, more than one company will get a contract to build prototypes for Army testing. What's the objective that drives both this pace and the technological tradeoffs the Army is willing to make? Fielding the first operational unit in 2026 — nine years earlier than the original plan — to help deter Russian aggression. Deadline 2026 “All options are on the table, but the schedule will be the schedule,” Brig. Gen. Coffman told reporters at AUSA. “We would like to field this vehicle by 2026.” “If someone could develop a clean sheet design that could meet that timeline,” he said, “it'd be great, but I don't know that's doable.” (By contrast, the potential replacement for the M1 Abrams tank is coming later, so the service is looking for radical innovation). Schirmer offered more specifics. “We have a pretty challenging test schedule... very similar to MPF, (so) we really can't afford a clean sheet design,” he said. The more mature the component technologies, the better, he said, but what's best is that those individual components have been proven as an integrated system. Specifically, Schirmer said, “for the Bradley replacement, we are going to be buying vehicles that are based on a mature architecture — powertrain, track, suspension — that's already in service somewhere in the world.” While these remarks leave the door open for the Lynx, or at least ajar, they're not particularly encouraging. By contrast, the CV90 series entered service with Sweden in 1993, with variants now serving in Denmark, Estonia, Finland, Holland, Norway, and Switzerland. The Griffin III is the latest member of the ASCOD family — the Spanish Pizzaro, Austrian Ulan, and British Ajax — which debuted in Spain in 2002. While the Army wants a proven hull, however, Schirmer says there is one area where technology is advancing fast enough for it be worth taking some risk: lethality, i.e. the gun and sensors. In particular, while the Bradley has a 25mm chaingun, the Army really wants NGCV to have a 50mm cannon — firing shells about four times as big — that's now in development at the service's Ammunition Research, Development, & Engineering Center (ARDEC). That gun, the XM913, is currently integrated on just one competitor, the Griffin, although both the Lynx and CV90 turrets could accommodate it. All three vehicles, like the Bradley, also have room in the turret to mount anti-tank missiles of various types. The Griffin on the show floor also mounts a launcher for AeroVironment Shrike mini-drones, while the Lynx will have the option to launch Raytheon's Coyote: Both mini-drones can be configured either with sensors to scout or with warheads to destroy. Even on weaponry, however, the Army is willing to make compromises to speed fielding, just as it introduced the original M1 Abrams with a 105 mm gun but with room to upgrade to the desired 120mm when it was ready a few years later. For NGCV, Schirmer said, they want the vehicle to have the 50mm gun eventually but “may settle on the 30 in the near term, just to meet schedule.” Armor & Passengers Besides gun caliber, the other easily measured aspect of an armored vehicle is its weight, which is very much a two-edged sword. There's been no breakthrough in armor materials since the 1980s and none on the horizon, so the only way to get better armor is to make it thicker. So a heavier vehicle is probably better protected, but it also burns more fuel, wears out more spare parts, and has more trouble getting places: Bridges and transport aircraft in particular can only take so much weight.

  SCAF : la phase du démonstrateur est lancée

  Les gouvernements français et allemands ont notifié à Dassault Aviation, Airbus, MTU Aero Engines, Safran, MBDA et Thales le contrat cadre initial de démonstrateur du Système de combat aérien du futur (SCAF) Les gouvernements français et allemands ont notifié ce jeudi 13 février le contrat cadre initial de démonstrateur du Système de combat aérien du futur ou SCAF aux industriels français et allemands associés au programme. En l'occurrence, Dassault Aviation, Airbus et leurs partenaires MTU Aero Engines, Safran, MBDA et Thales. Cette notification était attendue à l'occasion du dernier salon du Bourget en juin 2019, puis avait été repoussée pour l'automne. En parallèle aux discussions serrées entre partenaires industriels sur la répartition du rôle de chacun, les gouvernements français et allemand devaient trouver un accord concernant l'exportation des systèmes, dont le SCAF. Un véritable enjeu pour les industriels impliqués dans ces programmes car leur permettant de trouver des débouchés commerciaux et de pérenniser leurs activités. Et le 16 octobre 2019, Florence Parly, ministre des Armées, pouvait annoncer : « Décision fondamentale qui acte une confiance mutuelle : un accord a été conclu aujourd'hui entre France et Allemagne. Il permet l'exportation d'équipements issus de nos coopérations. Etape essentielle pour construire sereinement une Europe de la défense ambitieuse ». Florence Parly indiquait également que le contrat visant à lancer de démonstration pour le NGF ou "New Generation Fighter" devait être signé "dès janvier 2020" et que "le premier vol devant ensuite être réalisé en 2026". « Cet avion de combat du futur et les drones qui l'accompagneront entreront dans nos forces à l'horizon 2035/2040 », avait précisé Florence Parly. Le contrat cadre notifié aujourd'hui porte sur une première phase (Phase 1A) de 18 mois et lance donc les travaux qui mèneront au développement d'un démonstrateur du NGF avec pour rappel Dassault Aviation associé à Airbus pour le NGF, Airbus et MBDA sur les "remote carriers" à la fois drones et missiles et dont le rôle sera de saturer les défenses ennemies, mener des missions de brouillage, désigner des cibles ou même larguer des missiles; Airbus et Thales sur le "combat cloud" (mise en réseau informationnelle et opérationnelle de tous les éléments du SCAF), et Safran et MTU Aero Engines sur la motorisation du SCAF. "Les entreprises concernées développeront conjointement un environnement de simulation visant à garantir la cohérence des différents démonstrateurs". https://www.air-cosmos.com/article/scaf-la-phase-du-dmonstrateur-est-lance-22559
