Germany always wanted to have strategic bombers like the cool kids, their problem was that their aircraft industry was nascent due to the ban on military aircraft production in Germany and thus the need to start it up from scratch in the 30's (barring a few clumsy attempts at trial building bombers as "mail planes" in Swedish factories). Since 4 engine aircraft are pretty complex Germany wasn't up to the task and it was simply easier to produce single and double engine aircraft, both of which worked well for ground support missions. That being said, it was always envisioned that the He-111 and the Ju-88 in particular would be "dual purpose" bombers, able to perform both ground support and strategic bombings. When the Ju-88 failed to evolve into an aircraft capable of larger bomb loads this idea fell through. The problem was that the actual strategic bomber, the He-177, was repeatedly delayed from deployment due to technical issues. Having been ordered in 1936 and having its first flight in 1939 it was deployed first in 1942, way too late to serve in its intended role or having much of an impact on anything.

It is not that the Luftwaffe didn't want to be able to lay waste to entire cities like the Combined Bomber Offensive did, it is that they didn't manage to get the necessary aircraft to do so until it was too late.
Surely the plan for the war was to quickly conquer and occupy enemy territory while still valuable as the German economy would not survive a lengthy war?

Also, I had read that one of the limitations on 4 engine aircraft was simply a limitation of the number of engines they could build, and 2 engines bombers obviously require less.

As I understand it, that was mostly Hitler's interference. Hitler maintained a fairly irrational belief that strategic bombing would destroy the allies will to fight (which probably derives from his political views on the weakness of liberal democracy) and placed a huge amount of stock in the idea of the vengeance weapon attacks on allied cities.
In a way, I can sort of get why they might want to take the UK out. If the UK did pack it in, the US forces would likely also go home, and then Germany could dream it still had a hope in hell of resisting the Soviets - although presumably part of that fantasy was persuading France and the UK to change sides and pitch in against Communism.

It was also hugely expensive. As in: The V2 project was more expensive then the entirety of the Manhattan Project and the latter had far more of an impact on both the war and the post-war power balance.
The Germans could have used the same resources to build ~3000 Panzer IVs: Enough to equip over 20 Panzer divisions with tanks. Admittedly, they didn't have the manpower for another new 20 Panzer divisions by then, and I suppose if you include all the other stuff (artillery, guns, armoured cars, lorries), you'd get much less than 20 Panzer divisions. But they could have re-equipped their existing ones, most of which were permanently underequipped by 1944.

Blitzkrieg was more about technology of tactics rather than equipment.

Everyone had dive bombers. It's just only the Germans could use them effectively in the early war because dive bombers depended on air superiority. And the famous dive bomber was the Junkers 87 ("Stuka"); Messerschmidts were the classic fighter planes.



Yeah, but they were useless. Sure, one might occasionally land on a target as big as London, but it's just going to kill a few civilians and they really should have learnt after trying to flatten the UK with aircraft bombs that they were not onto a winner that way.

I mean, the UK achieved more than whole German armies by inventing a computer. Or vastly superior radar. These things might not seem so flashy, but they were a damn sight more useful than the expensive, inaccurate, glorified fireworks Werner von Braun came up with.
A lesson all should take away from WW2 is that we should never underestimate how much an unwillingness to fight can level the playing field.

What's funny, is that they probably could have done more with trucks than more tanks; most of the German army (with the exception of Panzer units) throughout the war used horses to move their equipment around such as artillery pieces and other logistics.

I'm rather partial to the Super Heavy Tank T28 (the official term, more properly it's an assault gun, also known as the 105mm Gun Motor Carriage T95). Just because of how fun a concept it is, a tracked fortress built to break the Siegfried Line and/or defenses on the Japanese Home Islands.

36 feet long, 9 feet tall and 14 feet wide, with a loaded weight of 95 tons and a top speed of 8mph. Quadruple tracks to reduce ground pressure, complete with a small crane on the rear superstructure to assist with removing them (so it could fit on a railcar), each double-track set was 23 inches wide, and with a 500hp (5.3hp/ton) engine it wasn't exactly the most mobile vehicle. Instead it was made practically invulnerable from the front with up to 12 inches of solid armor. And a T5E1 105mm/65-calibre gun paired with a tungsten carbide high-velocity armor-piercing (HVAP) shell reaching 3700fps would allow it to punch straight through the armor of a Jagdtiger at 1100m.

Unfortunately for fans of ridiculously huge vehicles, the war ended before the T28 was put into production and it was rendered obsolete by turreted designs with comparable firepower and protection. Though there is a pretty hilarious addendum to its story. Pacific Car and Foundry built two prototypes for the Army in 1945. Both underwent extensive testing for several years after the war, with one eventually being destroyed by an engine fire and scrapped at the Yuma Proving Ground in 1947. The other one...well, that's where it gets funny.

The Army lost it. For twenty-seven years. Where it went after testing wrapped up in 1947 is a complete mystery, but somehow the Army managed to lose track of a 100-ton superheavy siege machine until 1974...when an officer out for a walk at Fort Belvoir, Virginia found it sitting in a patch of bushes. For a while after that it was displayed at Patton Museum of Cavalry and Armor at Fort Knox, until being relocated to Fort Benning in 2011. And while in transit for restoration in 2017, it fell off the M1070 heavy transport truck carrying it and rolled into a ditch...which managed to lightly damage two track bogies. Nowadays it's back at Fort Benning, at the National Army and Cavalry Museum.

Oh yeah also in 1942 the British were kicking around the idea of attempting to commit genocide on the Germans. The plan was called Operation Vegetarian. The idea was that bombers would drop cakes of anthrax onto Germany, which would disperse spores that would infect cattle and therefore the humans that consumed them, killing millions through the disease, and millions more through starvation. To test the viability of this, some sheep were put onto a small Scottish island called Gruinard and Anthrax bombs were dropped on them. The island was thoroughly contaminated, and the researchers involved were satisfied that the island would be lethally contaminated for decades to come. The cakes were prepared and ready to be dropped by 1944, but by 1944 the D-Day landings had happened and the war was thoroughly against Germany, so the annihilation of Germany through biological warfare was avoided. If it had gone ahead and worked as intended (It's uncertain as to whether the cakes could have been distributed widely enough) the death toll would have been catastrophic.

The Germans could have used the same resources to build ~3000 Panzer IVs: Enough to equip over 20 Panzer divisions with tanks. Admittedly, they didn't have the manpower for another new 20 Panzer divisions by then, and I suppose if you include all the other stuff (artillery, guns, armoured cars, lorries), you'd get much less than 20 Panzer divisions. But they could have re-equipped their existing ones, most of which were permanently underequipped by 1944.
This wouldn't have done them much good because they didn't have any oil but then you're getting into the whole territory of how the entire war was unwinnable for Germany unless you completely change the terms of it by making the Nazis not raving fascist antisemites.

So yeah, apparently this ridiculous thing reached the prototype stage, but only one was ever actually built. It's not entirely clear what it was meant to be for, but given that it wouldn't have stood a chance engaging other vehicles it was probably meant for infantry support (already a fairly dubious concept for a specialised armoured vehicle role). But.. just look at it. It's so dumb.

You know you're doing something right when your tank looks more ridiculous than something built by the orks in Warhammer 40k.

It's why Nazi Victory AU scenrios tend to either invovle a masssive change in starting conditions or end up making some assumptions that come across as unrealistic as best.

Case in point, this AU for Paradise Lost where the USSR, UK, USA, Japan and Italy just decide not to do jack shit because reasons so the Nazis can get a Nuke and go full Belka

Uh...I don't think that's a real tank. That looks like an M3 Lee tank with extra cannons stuck on it, which if they were real would leave no room for the crew (and I think that front lowest gun would be sitting in the transmission).

I like the idea of towing the UK onto the French coast so the Nazis can invade without dealing with the channel.

Maybe. The Germans had a perpetual, critical problem with low oil supplies. Arguably, that their army was still relatively backward in its dependency on horse-drawn transport was, in ways, not worth them rectifying. In things like the Battle of the Bulge, you see their strategic planning specifically aiming to capture supply dumps because otherwise the offensive would be hampered by them constantly running out of fuel.

Uh...I don't think that's a real tank. That looks like an M3 Lee tank with extra cannons stuck on it, which if they were real would leave no room for the crew (and I think that front lowest gun would be sitting in the transmission).
No, that really is the sort of stupid stuff they might get to prototype stage. There are several Russian tanks with a similar notion - like one central turret and up to six mini-turrets with lower calibre cannons. A few less absurd got into production like the T-35, but most never got past the drawing board. They're intrinsically failtastic because all that weaponry adds a lot of weight and size, therefore requiring fatal compromises to the armour or too much strain on the engine and drives. I cannot help but think many were not designed by experienced, professional tank designers.

I'm rather partial to the Super Heavy Tank T28 (the official term, more properly it's an assault gun, also known as the 105mm Gun Motor Carriage T95). Just because of how fun a concept it is, a tracked fortress built to break the Siegfried Line and/or defenses on the Japanese Home Islands.
Most nations designed something like this. The British designed the Tortoise, it's mostly what the Soviet mass-produced IS2 / IS3 was designed to do, and the Germans of course created the Elefant and Jagdtiger (although more tank destroyers than "bunker-busters"). They weren't intrinsically stupid, though: it's more just that the situation they were designed for turned out to not really be an issue: fortifications didn't turn out to be the obstacles feared. In terms of antitank warfare, the creation of ammo such as APDS meant there was little benefit in ever-increasing armour either as relatively light guns were far more effective, so heavy tanks rapidly went the way of the dodo after WW2 as well.

That still doesn't work because the Nazis thought nuclear physics was Jewish science so the German nuclear programme didn't really go anywhere.

Partly true. The guys leading the German nuclear physics program mostly knew what they were doing, and in practice managed to hold the line against political interference to get research done. The bigger problems were that nuclear research was low priority in Nazi Germany's R&D and lack of expertise having driven the many Jewish physicists out.

So everyone's heard the term "Flying tank" before. Well, ti turns out some people took it quite literally.


More of a gliding tank, as it was designed that wings would allow it to glide onto the battlefield, shed the wings and do tank things. Interestingly, this wasn't a terrible concept in execution, but the fact it needed specialized gliders and/or towing aircraft ended up killing the projects due to feasibility.

I mean, there are many reasons this doesn't work.

I particularly like how the UK just stands by as the German war machine rampages through Africa(and no doubt numerous colonial holdings) to the Germans can get Uranium so they can give themselves nukes. Italy and Japan don't even exist in this AU, apparently.

This is a particularly lazy WW2 AU, but apparently it's not a great game if the reviews are to be believed.
