Army Taking Another Look At JLTV
Mar 3, 2010
By Paul McLeary
U.S. Army Lt. Gen. Michael Vane, deputy chief of the Army Capabilities Integration Center (ARCIC), says that there is more work to be done in developing the concepts behind the Joint Light Tactical Vehicle (JLTV), hailed as the successor to the iconic Humvee for the U.S. Army and Marine Corps.
Speaking to Aviation Week at last week’s Association of the U.S. Army winter convention in Florida, Vane said the Army is “going to have to make some modifications to that in the requirements document, and both ourselves and the Marine Corps are largely in agreement [that] clearly some adjustments are going to need to be made.” Rickey Smith, ARCIC director, stepped in to add that “some of those are based on opportunities where the industry has done better.”
Vane continued, “I don’t think we challenged ourselves enough. On fuel efficiency on JLTV for example, I think we could do a lot better. We didn’t get any hybrid vehicles, we didn’t get anybody using alternative fuels. Why didn’t we? We set the bar too low.” When reminded that one of the rejected JLTV proposals was, in fact, a hybrid design — the submission by the team of Northrop Grumman and Oshkosh — Vane simply agreed that the design didn’t make the cut.
Smith also said that the Army is looking at a modular approach in all of its new vehicle designs, everything from the armor to the network package. Smith said this means building the vehicle with the ability to be easily upgraded every couple of years as technologies and missions change. The wars in Iraq and Afghanistan have taught the Army that “the ability to grow and change is an operational requirement,” Vane added. “You are going to change it,” the only questions are when, and what.

U.S. Army 'Moving Rapidly' To Add V-Hull to Strykers

Published: 3 Mar 2010 14:40
A double V-shaped hull could be added to the U.S. Army's Stryker vehicle quickly, the service's top uniformed official told lawmakers who voiced concerns about its survivability.
U.S. Army Chief of Staff Gen. George Casey told the Senate Appropriations defense subcommittee that the Army was working to get V-hulled Stykers to deployed forces as quickly as possible. (ROMEO GACAD / AFP) "I can't tell you exactly how long it's going to take, because we're in the early design stages of that, but we are moving rapidly to get it built, tested and into the hands of the forces as quickly as we can," Army Chief of Staff Gen. George Casey told the Senate Appropriations defense subcommittee on March 3.
In January, Stryker manufacturer General Dynamics presented the Army a plan to accelerate the introduction of a double V-shaped hull to the flat-bottomed Stryker, increasing the vehicle's protection against improvised explosive devices.
One source said the Army currently plans to reduce monthly Stryker production from 35 to 20 by January, which could delay the improvements. The source said that if the vehicle's production rate is held steady, the company could deliver 130 vehicles in the infantry carrier configuration in time for the next Stryker brigade's deployment to Afghanistan in July 2011.
In late February, Lt. Gen. Robert Lennox, deputy chief of staff for Army programs, said service officials intended to make a decision soon.
At the March 3 hearing, Army Secretary John McHugh said he's optimistic the Army will be able to field the V-shaped hull quickly.
"I think it's worth noting that the manufacturer recognized this early on and has been working on this and studying it for some time. That's a great compliment to them," said McHugh.
Casey said that the Strykers had received survivability improvements before they were deployed to Afghanistan.
"We are in the process of evaluating whether those are enough to operate in an IED environment," he told lawmakers.
Asked by Sen. Richard Shelby, R-Ala., whether deploying Strykers with a double V-shaped hull was "a probability more than a possibility," Casey responded, "Absolutely."
Subcommittee chairman Sen. Daniel Inouye, D-Hawaii, asked the Army leaders whether the vehicle was too heavy for some operations.
"I'm less concerned about the weight and the decrease in mobility," said Casey.
He said the Strykers in Afghanistan have been shifted "to a mission of road security that actually takes advantage of the mobility they provide."
The hearing was cut short for a memorial for Rep. John Murtha, D-Pa., but Inouye said he would submit further questions to the Army regarding brigade combat team modernization, the future role of the Mine Resistant Ambush Protected Vehicle, the Aerial Scout Helicopter and the Joint Cargo Aircraft.
Army Field Support Battalion Moves MRAPs to Meet Missions
(Source: US Army; issued March 3, 2010)
CAMP ARIFJAN, Kuwait --- The 2nd Battalion, 401st Army Field Support Brigade, commanded by Lt. Col. Michael T. Wright, is partnering with Joint Project Office (JPO) Mine-Resistant, Ambush-Protected (MRAP) to process MRAP vehicles more quickly, efficiently, and cost effectively.
The task is to reissue MRAPs returning from Iraq and deliver them to Afghanistan as fully reconditioned vehicles. The goal is to save time and reduce costs by eliminating unnecessary shipping and handling. To accomplish this goal, the 2/401st AFSB and JPO MRAP are working together to consolidate operations at one location.
Presently, convoys bearing retrograde MRAPs arrive at Camp Arifjan to establish accountability and undergo initial processing. The MRAPs are then transported to an off-site MRAP Sustainment Facility (MSF) operated by JPO MRAP. At the MSF, the vehicles go through an intensive maintenance and upgrade program run by JPO MRAP's prime contractor, Science Applications International Corporation (SAIC).
After maintenance and upgrades are completed, the MRAPs are transported back to Camp Arifjan in preparation for shipment to port. The trip to and from the MSF is both time consuming and costly; it requires loading and off-loading the vehicles twice, and the distance between the facilities requires at least one hour of travel each way. If everything were completed at one location, a significant amount of time and money would be saved. A recently completed storage and processing lot at the MSF opens up that very possibility.
The 2nd Battalion, 401st AFSB initiated a series of meetings with JPO MRAP, SAIC, and a contractor to analyze the problem. The battalion's Supply, Transportation, Contracting, Communications, and Support Operations subject-matter experts were present. These joint meetings brought about a refined definition of the requirement and a mutually agreeable course of action.
Wright decided to take a two-pronged approach: a team would be mobilized to go to the MSF to prepare ready-to-ship MRAPs for transport to the APOE and onward movement to Afghanistan. This no-cost solution required only a letter from the contracting officer, Michael Duncan, and eliminates the return trip to Camp Arifjan.
Step two will allow MRAP convoys to bypass Camp Arifjan and go straight to the MSF. This effort will require teams to receive, process, and account for MRAPs at the MSF on a 24/7 basis and be performed pursuant to a modification to the GMASS contract. A memorandum of agreement between the battalion and JPO MRAP will establish the terms and conditions of the working relationship. The battalion will have a uniformed liaison officer and contracting officer representative present at the MSF to provide oversight and facilitate communication between all parties to the agreement.
When fully implemented, the plan will build velocity, reduce cost, and exemplify how contractors and the military can work together to make the materiel enterprise work more efficiently.
I assume this "double v" means a 'w' shape on the hull yeah? how would that work? wouldn't it focus part of the blast up into the floor of the Stryker rather than deflect it all to the sides?

It depends how the hull shape is channelised. There are boats with ‘w’ shape hulls (called M hulls) that enable water to flow to the sides and rear.

Without changing the drive train and suspension any mine blast deflection hull on the LAV is going to be limited by height. So a full deep V is probably not going to fit. But two side by side Vs shapped to allow the central channel to work could provide enhanced protection.
Interesting that they are persisting with SEP developments...................

ummmm, depends ... maybe it is no coicidence that they annouce this just as the RFP for the GCV is out? Maybe i missed it but among all the teaming announcements for GCV recently, BAE was notably absent - and Kongsberg might have an interest to extend its US business beyond CROWS while iirc, BAE pitches the SEP for MPC in the US already anyways.
