You can’t wage modern war without diesel engines, those trucks won’t drive themselves close to the front-lines (and, no, electric-powered trucks in times of war are a terrible idea, and the ones powered by gasoline are a lot less efficient and don’t provide the same torque numbers).
Valid points you’re making. Let me make a counter point: as a German, I’ve seen tanks on 5/6 occasions in my life, never using their own engines. But at the same time, I’ve seen hundreds of cars every day and breathed their emissions. It’s totally fine if tanks continue using diesel, but cars, trucks etc. not using diesel (or gas) engines anymore will have a measurable effect on my health
I actually would also prefer modern stealth tanks battery or hydrogen/fuel cell powered.
Otherwise good point.
But then you'd also lose the capability of making diesel engines for good, and, again, they're not used only for tanks when it comes to warfare.
Just look at the hole the US has dug for itself when it stopped producing civilian sea-ships, nowadays the cost of producing or even repairing its war-oriented sea-ships is way too high. And not only that, but it doesn't have the people with the knowhow to build those ships anymore, no matter the money thrown at the problem.
That doesn't make much sense as military technology typically comes first before any civilian application. Also, it would imply that we should already have lost the capability of making tank tracks as civilian vehicles don't use them.
> have lost the capability of making tank tracks
Western Europe has certainly lost the capability of making even artillery shells at scale, let alone tank tracks, just look where we're at it now.
> as military technology typically comes first before any civilian application.
Diesel himself wasn't involved in any military thing, as far as I know, so I think you're wrong on that one.
The thing is that without a strong civilian industrial base focused on things adjacent to warfare (like the steel industry when it comes to building ships or artillery shells) any big power is going to come very short-handed in the next big war (assuming the war doesn't get nuclear, which is another discussion). So, if your country can't make diesel engines at scale, for whatever reason, then you can say goodbye to your logistics lines because you need lots and lots of trucks for said logistics as part of a continental war, i.e. forget the tanks.
> Western Europe has certainly lost the capability of making even artillery shells at scale
Must be due to the lack of demand for civilian artillery shells, right?
Why would electric trucks be a terrible idea in war time?
Short version is that you can't rely on the power grid or other centralized generation. Centralized infrastructure may not even be available, but if it is then the enemy can target it.
I'm not a tank expert, but my impression of Wehrmacht tanks vs Soviet tanks is the Wehrmacht tanks used aviation engines. Aviation engines are light and powerful, but don't have much life, were finicky, and require aviation gas. Soviet tanks were simple and used any liquid that would burn.
The US military is starting to use some hybrid vehicles to improve fuel logistics and reduce operating noise. But pure electric ground vehicles are obviously a stupid idea for combat usage due to charging issues.
