Can they survive an IED?
Another “boneyard” is about to be built and filled-up.
depends on how big the IED is.
That was the primary requirement that initiated the replacement of the HMWWV.
The obvious higher ground clearance is a key characteristic to dissipate blast
In terms of UBB (Under Body Blast) protection, air is a cheap and potent help. As illustrated below, the distance between the source of an explosion and the truck is critical, as pressure decreases rapidly as a function of distance. So every inch that can be afforded to increase the distance of a truck’s underbody from a buried explosive yields a major protection benefit.
Reflected Pressure vs. Distance From Burst Point for 20 lbs of TNT.
The JLTV features large tires and a suspension that gives its hull a high ground clearance, comparable to the approximately 2- to 3-ft ground clearance for MRAPs. By contrast, the HMMWV has a clearance of only about 14 inches from the ground to the bottom of its hull.
I wonder what Track time it will end up with on The Nürburg-Ring.
Oh wait ,the most important thing is are they environmentally friendly , LOL
I realize that vehicle design must keep up with need to protect troops in the ever changing battle field.
But for crying out loud, I’m wondering to what extent the military-industrial complex adds to this “need” just to keep tax dollars flowing in their direction?
This new vehicle will not be the end, there will be more.
Only the military could officially label a 20,000 llb vehicle LIGHT!
Can a Humvee?
How did those clinkers ever get past testing phases?
A Hummer certainly couldn't if that is your standard of reference. An MRAP might if the IED is small enough. An M-1 might not if the IED is big enough.
Were the contractors, designers and builders screen for diversity purposes? Were there the appropriate amount of inclusion of LGBTQIA+ people? Was the management of this project sensitive to affirmative action in their ranks?
The HMWWV has had a 35 year run. It’s not going away any time soon. The many variants will be around for the foreseeable future. The JTLV will go where survivability is most vital.
Scalable for different uses. https://oshkoshdefense.com/vehicles/jltv/
The base vehicle (general purpose model) is only about 10,000 pounds, with significant blast protection - about a ton less than an up armored HMMWV, and in the ballpark with the Ford F-250 pickup truck.
Even in ‘93 I had one of those M1009 Chevy Blazers for a couple months.
“The HMWWV has had a 35 year run. It’s not going away any time soon.”
As front line units get the new stuff, their HMMWV’s will get transferred to Reserve and Guard units, into the Depot system, or go to Foreign Military Sales. We will probably see them somewhere for a good twenty or more years.
“How did those clinkers ever get past testing phases?”
You can’t get a ball bearing through the whole Military testing process without some criticism.
The windows are smaller to better protect from blast effects. It is a trade off.
