Philippe Top-Force Posted January 18, 2010 Share Posted January 18, 2010 Dit moi belle brune, tu m'attaques par les sentiments? En fais, ce que j'aime bien, c'est le Sandcat. Adriana te dirait que l'on n'est pas fichu de commander des Spike ER aux israéliens, alors un Sandcat :lol: , de plus des véhicules blindés et surblindés, on a une petite gamme à faire vendre à l'export et surtout à restructurer les véhiculiers à adosser à un géant industriel.

g4lly Posted January 30, 2010 Share Posted January 30, 2010 http://www.defpro.com/daily/details/495/ 08:32 GMT, January 28, 2010 The Joint Light Tactical Vehicle, or JLTV Technology Development (TD) phase industry teams have begun to build government prototypes, engineering an unprecedented blend of mobility, payload capacity and survivability - building a light tactical vehicle that will withstand improvised explosive device (IED) attacks, drive quickly through diverse terrain and transport beneath a CH-47 or CH-53 helicopter. The three teams awarded contracts for the 27-month TD phase - BAE-Navistar, General Tactical Vehicles, and Lockheed-BAE - have incorporated design revisions from their independent preliminary and Critical Design Reviews (CDR). “The Joint and International JLTV program is one of the first Department of Defense (DoD) acquisition programs to embrace the principles of ‘Competitive Prototyping.’ Through the efforts of three contractors to build JLTV variants we can validate requirements and reduce risk,” said U.S. Army Colonel John Myers, the project manager for Joint Combat Support Systems. “Independent CDRs provide the Army and Marine Corps with the opportunity to assess the technical maturity of each team's design relative to the TD phase requirements. As we progress from Preliminary Design Reviews to CDRs, each team further refined their design - Then we move into the build process. What the Government sees coming out of the CDR is what we should see in hardware when the vehicles are delivered for testing,” said Army Lt. Col. Wolfgang Petermann, product manager for JLTV. Prior to testing, a series of independent test readiness reviews will serve as a checkpoint, ensuring that the vehicles were built as designed; the idea is to make sure that what was delivered on paper is the what is subsequently delivered in hardware, Petermann said. “Shortly after the test readiness reviews we will begin full vehicle testing, beginning with safety certifications. We will then move into performance and RAM [reliability and maintainability] testing. We will conduct user evaluations with soldiers and Marines to verify requirements suitability,” Petermann said. “This is a robust test program not typically seen in a TD [technology development] phase.” The prototypes will undergo 20,000 miles of RAM testing per vehicle, Peterman said. In addition to prototype testing, each of the three JLTV industry teams delivered armor coupons and a number of ballistic hulls for blast-test evaluation at Aberdeen Proving Grounds, Md. Industry partners have also conducted a series of subcomponent tests to include examinations of the adjustable height suspension, power integration capabilities, C4ISR architecture and blast-testing of the ballistic hulls, Petermann said. “We have seen many mature individual technologies. The challenge will be seeing them integrated,” Petermann said. At the end of the rigorous testing schedule, the prototype vehicles will go through extensive prototype live-fire tests where they are attacked in combat-like conditions by weapons most likely to be used by current and future enemies. The TD phase is aimed at informing and refining the requirements for the JLTV family of vehicles through prototyping in order to reduce risks and lower costs of production. Upon completion of the 27-month TD phase, the government will conduct a new, full and open competition for a follow-on Engineering and Manufacturing Development (EMD) phase, leading to the awarding of two contracts. “Our intent is to come out with an RFP for the EMD phase with a low-risk, executable and affordable set of requirements. We anticipate an RFP release for April 2011 - to be followed by a contract award in fourth quarter 2011,” Petermann said. Following a Milestone C decision in 2013, the Army plans to purchase 55,000 JLTVs and the Marines plan to buy 5,500. Full production is slated for 2015, Petermann said. The Army-Marine Corps JLTV program will produce a fleet of tactical vehicles that can support a range of mission sets. “We are developing a family of vehicles and companion trailers that can be used in any operational environment - low intensity conflict to high intensity conflict-Major combat operations to hybrid warfare. We have the SOCOM [special Operations Command] requirements built into the vehicle, meaning no follow-on modifications will be necessary to accommodate their mission profiles - thus increasing commonality with the operating forces,” said Lt. Col. Ben Garza, JLTV program manager, Marine Corps. Other requirements include building a vehicle that can generate 30 kilowatts of exportable power, drive when tires are shot, accommodate scalable armor solutions and extra spall liner and embedded diagnostics. “The unarmored Humvee used to have great payload capacity and off-road mobility, but when you added armor it threw it off balance. We want to regain that off-road mobility we had with increased survivability - all on one transportable platform,” Garza said. Currently, there are three payload categories which cover 10 JLTV configurations. Category A, the smallest category will have a combat transport weight of 14,322 pounds and supports a 3,500-pound payload while armored. Category B is somewhat larger supporting a 4,500-pound payload while armored; Category C supports a 5,100-pound payload while armored. The Category C vehicles will also address shelter and ambulance requirements. The entire family of JLTV is transportable by tactical assets (CH-47, CH-53, C-130), greatly reducing the burden on strategic assets such as the limited quantity of C-17 and C-5 aircraft. Also, JLTV family of vehicles will be able to adjust its suspension to a height of 76 inches or less in order to board Maritime preposition force ships, Garza said.

Vu la pléthore de producteur de véhicule tactique léger nationaux ... Accessoirement le PVP n'est pas dans la catégorie JLTV du tout. Le programme JLTV ne remplace que le gamme Humvee "combat", en gros l'équivalent de notre "VBMR 10t" et donc de notre VAB actuellement. La gamme Humvee utilitaire non blindé se poursuit. Y a eu plusieurs millier de commande récemment encore. Link to comment Share on other sites More sharing options...
alexandreVBCI Posted February 3, 2010 Author Share Posted February 3, 2010 Bye Bye Humvee ! It’s with great sadness that I report to you that Pentagon Comptroller Robert Hale just said at his briefing that 2010 would be the last year that the Pentagon would buy the venerable High Mobility Multipurpose Wheeled Vehicle. Budget documents released today show that the the Pentagon is devoting about $1 million to replace war losses of Humvees, but will buy none over and above the current numbers. The Pentagon budgeted for about 8,000 Humvees in FY 2010 to the tune of $1.3 billion. We’ll likely get more info on how serious the Army is about the JLTV, the Humvee’s replacement, at the Army breakout in a few minutes. But it’s just gigantic that the newest budget zeros out funds for the Humvee. Since about 1985, the Humvee has served very well in a variety of roles both as its originally intended support vehicle role and as a no joke combat vehicle in Iraq and Afghanistan. About 100,000 have been produced in various configurations for the US military. I’ve logged many hours in Humvees of various configurations and I had to good fortune to travel to Mishawaka, Ind., and South Bend, to see the production facility and drive the AM General test track in an uparmored Humvee. I’m psyched about the possibilities of the JLTV and feel that it’s high time we moved away from the Humvee, but I’ll look back with great affection at that cramped, dusty, bumpy, creaky, stinky, hot, bull-dog-tough truck. UPDATE: Army budget officials Lt. Gen. Edgar Stanton said at the breakout that “we reached the end of the line with the Humvee a sooner than we expected.” Fewer losses in Iraq and Afghanistan and the introduction of the M-ATV makes for “fewer uses for the Humvee.” http://defensetech.org/2010/02/01/bye-bye-humvee/ Link to comment Share on other sites More sharing options...

Serge Posted February 26, 2010 Share Posted February 26, 2010 Non, il faut remonter à l'AML.La France maitrisait la pliure de l'acier: À partir d'une plaque, on savait comment faire un "V" pour éviter les soudures et leure faiblesse balistique.En vendant les AML aux sud-africains (baptisée Elan), on leur a donné ce savoir-faire. Ils vont l'employer très tôt avec les premiers véhicules adaptés au minage de harcellement de la SWAPO dans le Sud-Ouest Africain (Namibie maintenant).Ils vont faire murire cette méthode grâce aux blindés de la SADF (Ratel, Buffel...) et du Koefoet (prononcer Koufoute (la pince), unité COIN de la police. Leur blindé fut le Casspir).A la fin de la "Border-War", les sud africains se sont retrouvés avec une grosse expérience dans la guerre des mines. Ils ont travaillé pour les marchés de déminage qui se développent en Yougoslavie, Cambodge... Années 90, une version boostée du Casspir voit le jour: c'est le Lion Mk3. Il a un radar anti-mines et un bras de fouille!!! Force-Protection aux EU en achette les droits. La guerre commence en Afghanistan, Force-Protection présente son Buffalo..

Tango Echo Posted July 1, 2010 Share Posted July 1, 2010 Ben il y en a pleins qui vont faire leur patrouille entièrement a pied pendants un bout de temps O0 T'inquiète pas pour eux Babou je peux te certifier qu'ils ne restent pas longtemps sans véhicules les US! :lol: En effet, le budget de la défense est autrement différent du notre! et pour cause cela se compte en centaines de millions chez eux alors que nous nous peinons avec nos dizaines de millions. Enfin faut comparer ce qui est comparable bien sûr, le pays est beaucoup plus gros que le notre et leur armée je n'en parle pas. Quoi qu'il en soit tu as pu avoir un aperçu de tout ce que j'ai pu voir dernièrement et je peux t'assurer que les livraisons de véhicules type MRAP il y en a tout les jours et pas par 2 mais par plusieurs dizaines. Du coup quand j'étais dans le sud, ils viraient tout leur Humvee pour passer au M-ATV et autre Cougar dont je n'ai pas pu compter le nombre tant ils étaient nombreux. Tout les jours ils finissent de monter les derniers matériels dessus (trans, brouilleurs, armement, etc) et ils livrent aux utilisateurs sur place. Dans le camps ou j'étais ils ont changé tout les Humvee du camp en une seule fois et ont perçu 24 M-ATV d'un seul coup! autant que de VAB dans nos régiments d'infanterie! pour te dire combien ils ne trainent pas longtemps à pieds :lol: Link to comment Share on other sites More sharing options...

g4lly Posted July 23, 2010 Share Posted July 23, 2010 Pas mal pas mal ! La remorque pour un transport de munitions ? Marrant sa me rappel les chenillette genre UE ou Lorraine le système la ! =) On dissertait avec EOD sur le manque de volume de l'Aravis. En effet plus de blindage a masse contrainte implique moins de surface blindé donc moins de volume sous blindage. Et j'avais émis l'hypothese de placer un remorque au cul de l'Aravis pour que les équipes EOD y case le matos qui rentre pas dans le tracteur. Il était pas convaincu de la tenu de route de la remorque en "tout chemin". Visiblement la solution remorque est envisagé dans le programme JLTV. Et c'est assez logique dans le cadre d'un MRAP. Séparer les élément de maniere qu'en cas de blast il sse détache sans exercer de contrainte majeur sur la cellule de survie. C'est exactement l'effet avec une remorque, si elle pete sur un IED ca s'arrachera sans excercer de gros dommage sur le tracteur. Reste a voir le surcout en masse de la remorque rapporté au volume embarquable dedans, et le comparer a un tracteur plus gros qui pourrait emporter la meme chose dedans.

Babou Posted July 23, 2010 Share Posted July 23, 2010 si ta remorque est une bete remorque pas blinder et tout ca doit pas peser des tonnes non plus...après on peut imaginer des remorques avec des moteurs électriques permettant de soulager les effort du tracteur et ca permettrait aux EOD d'avoir des alimentations électriques ;) Link to comment Share on other sites More sharing options...
Kiriyama Posted July 23, 2010 Share Posted July 23, 2010 En tout cas par rapport au Humvee on a une sérieuse augmentation de la taille et de la masse. Il faudra peut-être revoir les modalités de déploiement de l'engin (aérotransport). Link to comment Share on other sites More sharing options...
