I like this approach - test out the technology on an established platform and validate it in a realistic operating environment. I’d imagine the quiet battery only crawl mode could be very useful. Also the vehicle now becomes a giant charging point for all the electronic kit soldiers seem to lug around. Unclear whether there’s any direct connection from ICU to axle or is it a pure generator a la type 45 IEP

I think the stealth aspect is a bit overplayed, but perhaps at low speed a relatively small battery (2-3kWh) would allow you creep the last mile if needed.

A normal car does 2.5-4 miles per kWh at road speeds. And EV batteries are generally 40kWh plus.

RE:
Not sure the rationale behind the 2014 to 2016 gap in the data.

= the time when the UORs were brought back and most went thru the standardisation prgrm, ie. some fleets may have been mainly standing still for those years?

Yes, the best bits right at the beginning:

Designing the Foxhound there were only five requirements:

1. Turning Circle
2. Size/Weight
3. GVA architecture
4. Composite for anti-spall
5. Mine/Blast survivable

3 functional, 2 non-functional. 5 total fits the old management span of attention rule> The sec, the 'self' => 5 to spare :)

Requirements 1 through 1,995: ignore costs & schedule, just remember anyone but Bae.

A new version of Foxhound. That'll get the tongues wagging.

Distribute not just the drive elements, but also the batteries... which can double as structural elements
- a net weight reduction, less fuel consumption
"the battery has an energy density of 24 Wh/kg, which the team notes is around 20 percent of the capacity of today's lithium-ion batteries.

On the other hand, if this battery were integrated into an electric car in place of a typical lithium-ion one, that car would weigh a lot less and therefore require less energy to propel it across the ground. As for its mechanical properties, the team says the material has a stiffness of 25 GPa and can compete with other commonly used construction materials."

How do these batteries react to coming into contact with high velocity metal projectiles? Is there a fire risk?

Is there a photo anywhere showing a Foxhound next to a JLTV?

You don't see this one too often - as I believe none has been ordered. Would basically redo Jackal, which we have plenty of

Never seen one but they have been at the same shows so one may be out there.

Have yet to see the mobile invisible power station that will follow units around to recharge all their batteries. :D

They use the same engine, it's just hybrid drive through electric motors. Effectively replacing the mechanical transmission, and added benefit of brake regeneration into a small battery.

Stop clouding the debate with facts and objectivity! You should know most UKDF contributers don't like that sort of thing.

Rather please select out of context information to reinforce existing biases, and then come out with comments to the effect that no one in FMC, FLC capability areas, DE&S etc. etc. knows what they're talking about and that only UKDF armchair Admirals, Generals and Air Marshals can save the armed forces from themselves. You'll get far less push back that way, especially if you add the occasional frisson like 'civil servants on 7 figure salaries, boo hiss'.

Oh yes, and if you could mention that we really need to up-gun the Batch 2 River class patrol vessels with Trident nukes then that would be the icing on the cake.
