Pas encore le remplacant des hummers mais 1625 "mules" pour l'US SOCOM :

UV Country Inc., of Houston, TX received a maximum $28.4 million firm-fixed-price, 5-year indefinite-delivery/ indefinite-quantity contract for 1,625 Light Tactical All-Terrain Vehicles – an average of about $17,500 per vehicle. U.S. Special Operations Command will place orders as needed between April 10/09 – April 9/14 (H92222-09-D-0013).

ATVs have become popular with hunters and outdoor types, for their ability to carry gear into rugged, remote areas. Special Forces troops, who have the same needs, have happily adopted and adapted these small off-road vehicles to their own uses. UV Country carries Kawasaki products. The Mule 4010 4×4 weighs about 1,430 pounds, and can carry up to 1,330 pounds of gear on rear and roof platforms. The firm also carries Kawasaki’s Teryx “Recreational Utility Vehicle,” which has a very similar size and weight, but offers less cargo capacity (500 pounds, no roof rack) in exchange for an uprated engine that improves its mobility and towing capacity (1,300 pounds vs. 1,200).

Je me demande pourquoi il faut que la plupart des appareils electriques soient si moches ..

Ceci dit pour ceux qui parlaient de remplacer les Quads par des vélos ,il ne faut pas oublier que dans certains cas (en plus de porter deux personnes) ,ils tirent une remorque ..

BAE Systems has delivered two different M-ATV (Mine Resistant Ambush Protected All-Terrain Vehicles) prototypes to the U.S. Government for two months of testing and evaluation. Two different segments of the company’s Land & Armaments operating group, produced a version for consideration.

M-ATVs are tactical vehicles designed for U.S. soldiers and Marines in Afghanistan. They are lighter, more mobile versions of the first-generation MRAPs, that can provide comparable protection from roadside bombs, explosively formed projectiles, and rocket propelled grenades when using appliqué armor.

M-ATV

The M-ATV developed by BAE Systems’ U.S. Combat Systems (USCS) line of business is the product of more than 30-months of mine-protected light tactical vehicle development. This M-ATV has completed thousands of test miles and scores of blast and ballistic tests.

“This vehicle has the survivability of an MRAP and the mobility of a HMMWV,” said Matt Riddle, Vice President and General Manager of USCS. “It has the optimum capabilities needed by our troops in Afghanistan.”

The vehicle drew on the developmental experience of the nine RG-33 MRAP variants, providing the same level of armored protection at a reduced vehicle weight. The company quickly designed, developed, produced and fielded over 2,000 RG-33 vehicles from 2007 to 2008 to meet the urgent government need for armored tactical vehicles.

With a curb weight of less than 9 tons and an incredibly high power-to-weight ratio, this

M-ATV offers better dash and slope speeds than any other ground vehicle in the U.S. inventory. The vehicle has a low center of gravity to prevent roll-overs and ensure maximum off-road mobility.

The vehicle features a rugged, commercial turbo-charged diesel V8 engine with a top speed of 80 mph and best-in-class fuel economy. It features a fully independent suspension that ensures superior mobility over rocky and steep terrain when compared to the standard straight axle systems of traditional MRAP vehicles. It also generates 10 kilowatts of vehicle host power and an additional 20 kilowatts of power for export and mission equipment.

The company’s USCS business is a leader in the creation and fielding of combat vehicles, including the Bradley Fighting Vehicle, the M113, the RG-33 series, MRAPs, the Medium Mine Protected Vehicle, and the Amphibious Assault Vehicle, and is the lead developer on several of the ground combat vehicles for the U.S. Army’s Future Combat Systems.

Le pixellisé avec des si gros pixels ça me choque toujours .

La taille absolu des "pixel" dépend de la distance a laquelle l'ennemi est senser observer. Ce qui import c'est le champ occupé par le pixel dans le regard de l'observateur.

Autant un fantassin peu se trouver a 30m de sa cible ... autant un Vehicule va préserver des marge plus conséquente ... et donc avec des pixel plus gros. En gros on doit prendre comme base plusieurs centaine de mettre pour un vehicule ... contre plusieurs dizaine de mettre pour un fantassin ... et de l'ordre de quelques kilometre pour un aeronef ou un bateau.

Brigadier General Michael Brogan, the Marine Corps program officer for MRAP said this afternoon that he expects Oshkosh to deliver all 5,244 MRAP All Terrain Vehicles (M-ATV) by the end of March, 2010.

The $1 billion contract for the tactical vehicle, envisioned as a replacement for the lighter-armored Humvee in Afghanistan, was awarded yesterday to Oshkosh, and Brogan said that the company is slated to deliver the first 10 vehicles by the end of July. After that, the manufacturing process will increase quickly, with the company expected to be able to produce 1,000 vehicles per month by December. The first vehicles should be on the g round in Afghanistan by September or October.

Speaking on a conference call this afternoon, Gen, Brogan said that “survivability was the ascendant criteria” in the competition, and that “the Oshkosh vehicle proved to be the most survivable platform,” and that “at the end of the day, Oshkosh was superior in technical, superior in production [capability], and second in cost.” When asked about the possibility of a protest by one of the losing bidders, the general commented that “I don’t believe that it’s in the best interest of the warfighter, and I don’t believe that a protest will prevail.”

Getting the trucks to Afghanistan promises its share of headaches however. Gen. Brogan said that with the additional soldiers and Marines deploying to theater this summer and fall as part of the additional 17,000 troop commitment that president Obama has mandated, “the air bridge to Afghanistan is full,” so “we’re going to have to shoehorn” the vehicles into the theater, which is a “significant transportation challenge.” The plan calls for the first trucks to be flown in, the Pentagon hopes to transition to surface transport as soon as it can.

C'est une belle bête sacrément tout terrain. Il reprendra toute la gamme d'armement du HUMVEE ? (Stingers, Tow, 12,7 et Mk 19). La version qu'on voit là est avec ou sans blindage comparable à celui des HUMVEE servant actuellement ?

C'est un programme intérimaire de remplacement de l'Humvee pour l'Afghanistan, a priori il sera équipé de 12.7 et peut etre de LGA40. Sinon a vu de nez les vitre fond dans les 12cm d'épaisseur ... donc probablement un stanag niveau 4 ou pas loin.

Le chassis est celui des MTVR, seule la cabine est nouvelle est bénéficie des techno développé pour JLTV, ainsi d'une architecture MRAP. Mais on parle ici d'un engin de 14t ... en gros de la taille d'un Aravis ... mais avec juste 4/5 places :)

n'empêche c'est un sacré bestiau... Un peu comme si on remplaçait nos VBL par des Aravis  :rolleyes:

Ouaip mais avec deux moteur alors les Aravis :lol:

L'objectif du M-ATV est simple ... un vrai gros MRAP ... mais avec des réelle capacité tout terrain et une masse contenu pour les chemins type Afghanistan. D'ou ca super rapidement et en grand volume !

Donc oshkosh - qui s'est fait virer de JLTV - a réchauffé ses plat ... le chassis de camion tactique 4x4 MTVR un grand classique de l'armée US, et dessus une cabine issue de leur défunt projet JLTV. Il on confié le blindage a des spécialiste "plasan US" etc. L'équipement est ultra complet radio, navigation, camera, éclairage 360°, et le plateau arriere dispo pour acceuillir des modules missions plug & pley machin de la mort qui tue.

Le MTVR ... c'est ca ...

Oui et deux réservoirs aussi... on comprend au final pourquoi il n'y a que quatre places assises dans la bête :lol:

Je suppose que si tu leur demandes gentiment ils t'ammenage un fourgon tolé a la place du pickup ... juste que le projet M-ATV réclame un plateau pour des modules a l'arriere, et que visiblement l'armée US souhaite continuer a patrouiller a 5 par vehicule.

Oui, j'avais bien vu, je blaguais juste un peu. Ce qui me fait sourciller c'est le volume de l'engin. Bientôt on fera des patrouilles "légères" à bord d'engins de trente tonnes... on passe d'un HMMWV de quatre tonnes à un monstre qui fait presque quatre fois son poids pour les mêmes missions grosso modo!

La loi du MRAP version sudaf ... 700 fois ... c'est la masse du vehicule capable d'encaisser sans dommage pour les passager la charge d'explosif.

Le Frag kit 6 va quand meme etre déployé sur le parc de Humvee ...

Donc plusieurs chose, une protection contre les EFP, c'est les grosse caisse sur les porte, ca pese 490kg/m2 ... Des charniere de porte avec assistance électrique - en haut - les porte étant tellement lourde que sinon on peut pas les ouvrir, et un pare brise avant escamotable comme sortie de secours.

Accessoirement on retrouve le meme blindage épais sur les dernier MRAP lourd.

The Rock Island Arsenal Joint Manufacturing and Technology Center rolled out the newest armor kit to protect our warfighters May 8. The Fragmentation Kit Six or FRAG Kit 6, is the latest armor protection set for the Army's M1151 HMMWV.

The new kit boasts a number of improvements that are crucial to protecting the Soldier in the battlefield.

"One of the major differences is the boxes on the door," said Mike DeWitte, Production Unit Leader for Armor. "These boxes place more armor between Soldiers and projectiles. "

The new kit also boasts several safety enhancements as well. The kit comes with a Vehicle Emergency Egress Window.

"Adding the VEE window to the kit will allow Soldiers another way to exit the vehicle," Program Manager for the FRAG Kit 6, Phil Snyder said. "This window will help save lives."

RIA-JMTC has an order for more than 1,000 kits. In 2006, the arsenal produced over 6,000 FRAG 5 kits in a six-month time frame. The RIA-JMTC commander expressed his confidence in the workforce to deliver this crucial kit to those at the tip of the spear.

"This is a fine team and I'm very proud to serve with them," said RIA-JMTC Commander Col. Craig S. Cotter. "We all know this is a very serious business and we take it seriously. Our Soldiers are counting on us to do the best here."

The program manager for Tactical Vehicles echoed the importance of the kits that Rock Island was producing.

"The FRAG Kit 6 stretches humvee survivability to a new limit," said Program Manager for Tactical Vehicles, Col. Scott Kidd. "It is a limit that is highly necessary to a threat that we face today."

Also on hand for the roll out ceremony was Master Sgt. Jeffrey Mittman. Mittman was wounded by an improvised explosive device on July 7, 2005, while assisting an Iraqi Public Order Brigade in Central Baghdad as a member of the Special Police Transition Team. Since that day, he has worked to recover from the injuries he sustained. Mittman has seen the soft-skinned HMMWV used in Operation Desert Storm evolve to an armor platform that has saved countless lives and allowed warfighters to carry out critical missions today.

"Right here at Rock Island, you are producing the FRAG Kit 6, which is designed to defeat the specific weapon that hit me," said Mittman. "That FRAG Kit 6 will save lives on the battlefield."

As the first kits roll off the production line, the leaders and workforce know the importance of the mission that lie before them.

"Somewhere on a barren mountain top or filthy back alley somewhere our enemies are lying in wait. I will tell you that FRAG Kit 6 will give our Soldiers an edge. Enabling them to meet and defeat our enemies and come home safely to this land we love so much," said Cotter.

La facturant en carburant doit être énorme pour ces bestiaux. Sur ''De Defensa'', on avait sortit il y a quelques mois des chiffres de la consommation de carburant pour les forces en Irak qui était astronomiques. Et du fait que les raffineries en Irak ne sont pas grandes, ils importent de l'essence par pétroliers entiers. En Afghanistan, vu que les routes pakistanaises ne sont pas sur, c'est un cauchemar logistique...

Et dire que certains écrivent que les USA font la guerre pour le pétrole  :lol:
