Because, as I stated in my sarcastic suuuure line, the final drive is a very small target (and it's only exposed from some angles!). You'll note other armies have a conspicuous lack of 'oops all our final drives were hit by arty what a shame'. So either the man is bullshitting as to why the final drives broke, or the allies are actually putting their very best marksmen on artillery teams - with strict orders to aim only for final drives.
It's rather comparable to exclaiming that the enemy was scoring nothing but headshots on your infantry.
You'd think the Germans would realize that it's a wee bit unlikely that Karl and Ko destroyed *more tanks than they carried ammo combined*. Seriously, each JT carries 40 rounds at 100% stowage. Where did the ~30 extra kills come from, repeatedly limping into them with the JT's famous agility?
Thankfully, we have the soviet combat logs - Körner was ran over in a few hours, and they don't even bother to record meeting the vehicles in their logs. They spend more time whining about Panzerfausts.

Why yes, I do. Lets open it up. Nothing to suggest the incident in October 28th was anything but an above-average batch. Final drive complaints come back when fighting with the 654th picks back up in November.

And for reference, here is Noak's commentary from the later period. Final drive and track failures come back with a vengeance (yes, I'm suuure all of your final drives, the tiny targets that they are were miraculously hit by enemy artillery and that is why they failed).

I know all about the issues of parasitic mass and the like, 35% just seems to be a very high mass fraction for a modern 120mm (obviously, bore size plays a huge role in 'proper' sabot mass fraction) sabot made using a composite material. Old Soviet 125mm metal sabots had a *superior* mass fraction (approx 30-31%), with a wider bore requiring a larger sabot.
For what it is worth, the sabot mass fraction is ~20% of total projectile (Sabot + Rod) mass on 829A3. (Approx 2 kg sabot, calculated from the 4.4kg sabot of 829A1 plus AMPTIAC's numbers of Sabot weight savings generation over generation. 829A2 Sabot was 35% lighter than 829A1's Sabot, and 829A3's Sabot is 30% lighter than A2's.)
The 15% figure has been quoted for the change from L/44 to L/55 barrel retaining the same ammunition. Muzzle energy is 12.8 MJ for DM53 fired with the L/55 gun.
For the L/55A1 gun firing the KE 2020 Neo round, a 20% increase in performance has been projected - leading to 15.36 MJ muzzle energy.
At the current time, this remains speculation. Nexter has not revealed any specific details regarding the ASCALON concept, not even the caliber/bore diameter (Jon Hawkes initially tweeted that it would be a 140 mm gun, but he later corrected this claim).
As stated by Nexter, the 10 MJ muzzle energy are achieved at pressures below the current operational pressures of the 120 mm smoothbore gun family.
Some of the French 40s and 50s prototypes had pneumatic roadwheels, and I wonder if that was influence from the German 'expertise' they agglomerated post war. They did after all, also build some interleaved suspensions at this time - as well as desperately tried to get the HL 230 family to work to spec.
Poongsan produces the domestic K241 APFSDS in 90mm, as well as the licensed M431A2 HEAT and M71 HE (along with M353A2 training) - I assume these are the currently stocked rounds.
The old IHS Jane's ammo handbook quotes 152mm @ 60 degrees @ 1km for its performance. Take that with a grain of salt, although it is a tungsten rod.
It's rarely pointed out because it is an absolute load of bullshit, and most self respecting people have enough of a brain to not embarrass themselves in public by making such inherently absurd claims. Clearly you either have no brain or no sense of self worth if you are willing to put your name behind such an incredibly stupid line of thought.
Let us take, as a starting date, the year 1943, as that is nicely mid-war.
At that point in the war, the Western Allies were largely engaged in the Tunisian campaign, where other than defensive actions the entire battle of the Mareth line was decided via tactical maneuver, outflanking the defenses and thus rendering the line untenable and forcing an Axis retreat.
The final battle of Tunis, in May, featured a classic tactical breakthrough on a narrow front followed by exploitation by armored and infantry forces. Following the taking of the city, roughly 240,000 Axis troops, who had been defeated by maneuver, surrendered to the Allied forces there. They had been quite firmly defeated by being outmaneuvered, cut off, rendered irrelevant to the Allies achieving their objectives, and left with the choice of either dying pointlessly or surrendering. In fact, more surrendered than were killed fighting.
Following the Allied victory in North Africa, the invasion of Sicily was a 6 week affair, in which the Allies continuously advanced and took critical key objectives, forcing the Axis forces there to retire or be cut off, you know, as one does in maneuver warfare. Many times tougher than expected resistance was met, and rather than turn the battles into a slogfest, effort was shifted to where it could give the best results, and the results speak for themselves. The Axis were systematically and quickly evicted from the island.
In Italy, the landscape precluded maneuver warfare to an extent, but even there, after concentrated attacks on defensive positions (which did also feature maneuver on the allied side, but on a generally smaller scale) what happened? yep, exploitation maneuver by infantry and armored units forcing the enemy to retreat or surrender. One would notice that despite being on the offensive throughout all these campaigns, the Allies suffered lower casualties on the whole than the Axis did. How did they achieve such low losses? By utilizing their combat abilities better than the Axis did, and by exploiting successes to force axis retreats and surrenders at all levels.
By mid 1944, Italy had surrendered and was in allied hands, and it wasn't a result of sitting around with thumbs in uncomfortable places.
What else happened in mid '44? The largest amphibious invasion of history. And how was this invasion used to further the Allied goal of cleansing the Continent of the Nazi menace? Though maneuver warfare, primarily. The whole reason we hear so much about the Bocage and the attempts to break out of it was that the Allies didn't want to fight that kind of fight at all. Yes, they were better at it than the Nazis were, and yes their armored vehicles were better for such close range fighting as many big cat apologists like to point out to cover for the really sad showing the Nazi metal boxes gave in Normandy, but as far as the Allies were concerned it was a bad way of conducting war. And what happened when they broke out of the Bocage? again, again, maneuver warfare. The Falaise pocket was a result of highly effective maneuver warfare, and decisively kicked the ass of the Nazis at what they considered their own game. Even the Nazi troops who escaped the pocket did so without their heavy equipment, which was irreplaceable as Nazi production was entirely incapable of keeping up with war losses.
The following high speed chase to the German border was, again, brought about by maneuver warfare of the highest order, capturing several more Nazi units in various pockets, such as the Mons pocket and the Colmar pocket.
In addition to the maneuver battles, there were also some battles, such as Hurtgen, which were not battles of maneuver, but those were A. not as common, B. not preferred, and C. Occasionally unavoidable, as previously discussed. They were, however, followed by an exploitation, as a rule, where at this point in the war the main limits on the Allies rate of advance wasn't the German resistance, as much as it was the logistical hurdles of supplying fast armies across a country where most of the transportation infrastructure had been wrecked.
Following the Nazi winter offensive, which failed to achieve any of its primary goals, the Allies proceeded to, you guessed it, maneuver their way into the low countries and the Rhine. Including taking cutting off pockets of Axis troops at many locations.
To conclude, the idea that the Western Allies didn't use tactical maneuver as a tool is not only wrong, it is farcical, and paints you, personally, the person bringing this up as an idea, as an absolute idiot without a shred of common sense nor the brainpower to think before you open your mouth.
The hilarious thing here is that the Cletrac controlled differential on the Sherman, or the Merrit-Brown gearbox on what really is a wide range of British tanks, were hands down superior to what the Nazis were using in the vast majority of armored vehicles (Pz 3 and 4 and variants) they produced. And they had the reliability to go halfway across the continent on their own power, not break down after a measly few hundred km and need rail transport for any real movement.
Likewise, your other point is wrong on not one but two counts.
The first is that the idea of cruiser tanks and infantry tanks was confined to the British, not all or even most of the Western Allies.
The second is that by the mid war even the British were mostly out of that line of thinking, what with them operating very large numbers of American medium tanks (M3s and M4s in various variants) and effectively abandoning the development of infantry tanks in favor of ever better protected and armed cruiser tanks - with the introduction of the Cromwell, they had a tank which was a medium in all but name, with sufficient armor and firepower to go up against the common Nazi vehicles and win, while also being much more mobile.
dividing up the weight of the vehicle by adding roadwheel stations reduces MMP at the cost of more weight, which is an issue all Nazi vehicles suffered from extensively. As for taking bumps, the greater unsprung mass resulting from having more mass of wheels is a net detriment, and beyond 4 or so roadwheel stations per side there's damn near no extra ride smoothness to be achieved by adding roadwheel stations, the springs, whether torsion or something else, do that work.
Also, as has been previously noted in this thread, words have meanings and you are misusing them.
Faster off road speeds which never seemed to materialize owing to drivetrain unreliability, maneuverability which was forbidden in the manuals for fear of breaking the transmission, a general failure to use these theoretical abilities to do anything much, a repeated set of losses to allied maneuver operations, losing more vehicles than they could afford despite being on the defensive, all the way back to the Rhine. AKA, a piss poor combat record.
There are several good reasons to believe the solution was not the best, for example the entire rest of the world examining it and deciding it wasn't a good idea. The French even went the extra step of building a few of them, before discarding the idea into the dustbin of history, where it rightly belongs.
Everyone else was clearly capable of making tanks which weren't absurdly heavy for their combat ability and which could actually get to the battlefields and do their jobs. The extreme weight of the big cats is a detriment, not a positive. Also, by dint of not being excessively heavy, most Allied tanks had a much better power to weight ratio and could go faster, in addition to being much more reliable.
As did literally everyone else, yes. Shitty German steel would be a reasonable excuse for accepting reduced performance, not for creating horrible monsters which were entirely unsuited for fighting the war they were in the middle of. That anyone can make excuses for a """medium tank""" with the size and weight of a heavy but none of the performance thereof is absurd.
Usually, when one is guessing blindly, one shouldn't brag about being an absolute idiot who doesn't know what he's talking about, and listen to those who do.
This statement is entirely false. The overlapping wheels offer reduced ground pressure, at the cost of a whole host of other deficiencies, which are the reason nobody uses them any more.
Various napkin drawings of for the most part imaginary tanks do not imply they would ever have seen production. Especially not when such a change would require refitting entire factories to produce tanks which are only slightly different to ones already in production, and the need for said vehicles is acute.
In general, the square cube law favors larger tanks, but that doesn't apply when your tanks are made needlessly huge and heavy for no good reason. The overlapped suspensions, especially that of the Panther, came at a net weight penalty compared to other simpler suspension types, which means they come at a detriment to payload capacity, not an improvement.
lol. None of the operational analysis we have from WW2 supports this claim of yours. This is just pure fantasy on your part, which appears to be aimed at convincing yourself the Nazi tanks were superior... for some reason? One does wonder why you'd have such a fanatical devotion to the creations of the regime whose sole truly groundbreaking invention was the industrialization of mass murder.
you really have no clue how torsion bars work, do you?
Here's a hint: double length torsion bars and overlapping roadwheels are entirely independent design choices. Both of them are bad choices.
The 8.8 was quite a good gun as ww2 tank guns go, 100mm vertical is approximately equivalent to the armor of most medium tanks of the time, nothing to write home about when your tank weighs twice as much as a medium and that's all you get for your troubles.
Freezing mud and the like led to many big cats being flat out abandoned and not seeing combat, which means the combat effectiveness of those vehicles was a net negative. Again, hardly anything worth white knighting over.
The Allies, I would remind you, won the war. And they did so, on the whole, with lower casualties than the Axis suffered (in the West at least), and the general consensus among all of them was that there was very little to be learned from the Nazis about tanks. Before you go crying "victors", remember that the Allies were not above Operation Paperclip'ing any and all scientists they thought would be useful, and the Nazi tank designers didn't make the cut. The Allies didn't think they were worth stealing.
With overlapping wheels, you either get horrible track torsion loads or the maintenance nightmare of interleaving wheels. The only alternative is this:
The above also applies, in general, to the entire Nazi war effort.
For a Panther aficionado, you are extremely poorly informed about it. All Panthers had that 4 row interleaved roadwheel setup, with the outer wheels and inner wheels on opposing swing arms. While this layout is slightly better than that of the Tiger, it still requires the removal of an awful lot of roadwheels to get to any inner one, and still allows freezing mud to immobilize the vehicle.
wrong again. Even today, interleaved roadwheels would help reduce ground pressure, which for MBTs is reaching rather extreme values. But unlike then, nowadays everyone has the good sense to not mess around with unworkable ideas like that. Single torsion bars with dampers and bump stops gave a very good accounting for themselves in WW2, so your second point is also wrong.
Or, in other words: The Nazis correctly identified that vertical travel is important for high cross country speed, but instead of being sensible about how much vertical travel they needed they went with a value far in excess of what was actually useful at the time, and paid a horrendous price in design terms in order to achieve it.
There is a reason that even the postwar fast MBTs didn't have a vertical travel as large as that of the Panther, which was only done on the later NATO box tanks with much more powerful engines - below that point, it's just not very relevant.
Improvising by creating the most overcomplicated and resource intensive solution is not a very sensible answer when your problem is lack of resources.
Funny how even with very heavy tanks being used nowadays, many of which exceed 60 tons by a wide margin and have since they were designed, and in a wide range of extremely heavy engineering equipment, not only does nobody use overlapped or interleaved wheels, but literally nobody is even considering it as an option. perhaps, just perhaps, it is because the whole world knows it is a terrible idea?
Fortunately, this forum has an abundance of mechanical engineers, at least some of whom have experience with automotive systems.
Perhaps you should cease being so aggressively wrong when you yourself admit you have no clue what you're talking about.
If you made any, sure. For a start, you must first read the relevant literature, because as of now your arguments from ignorance only serve to accentuate your stupidity.
The T30 heavy tank features the CD-850 crossdrive transmission, which is a triple differential unit capable of both pivot turns and neutral turns. It also features a fuckoff huge torque converter, which allows a much easier driving experience as one only needs 2 gears forwards and one reverse to cover the entire range, and is in fact still in service today on a variety of vehicles. Which is more than I can say for any Nazi WW2 equipment.
I would like my million bucks, along with a punitive extra 1 mil for you shifting the goalposts from suspensions to transmissions yet still being horribly wrong.
and yes longer vehicles are harder to steer, but the magic number for tread-to-length is 1.5-1.8, and all Allied tanks of the late war period were perfectly fine in that regard. As Beer rightly notes.
You've gone straight into denialism. Tell me, do you also not believe the Allied reports on what they found in certain camps in Poland?
Regardless of what you choose or do not choose to believe, the Allies pretty much plowed through the Nazis in Europe, with the Nazis not achieving any great successes for all the divisions of brand spanking new tanks they threw into the grinder.
In conclusion, you are a total idiot blindly "defending" the products of a tyrannical regime despite lacking some very basic knowledge on the subject in general and of your specific favorites in particular. I diagnose you with a extremely bad case of Dunning-Kruger, the only known cure to which is this:
Your SNR is a net negative and the only reason you haven't yet been kicked off the forum for being a waste of electrons is that some people here still find your brand of idiocy amusing.
As far as I understand it, the rather key reason that the Luchs won over the n.A. (and the Luchs actually *failed* to meet requirements, the program required a 50mm gun and the best MAN could weasel out was they would have a new 50mm turret 'sometime' in the future for it) - was quite simple. MAN was both German and had lots of friends in the brass making decisions. The great irony is that they would basically have to beg for something to replace the nonexistent Luchs (as MAN was so overloaded with higher priority work, they never made more than the LRIP 100 tanks, and it was an epic feat for them to do that - more than a year at WW2 build pace!)... which resulted in the Sd.Kfz 140/1 being churned out for a few months before all Czech production was ordered to change to JgPz 38(t).
Always recommend the translated Pasholok piece here: https://www.tankarchives.ca/2018/07/reconnaissance-cats.html
It covers the sordid tale of Luchs and Leopard, and ends up discussing the 140/1 (Aufklärungspanzer 38(t)) at the end.
I just find it very amusing that MAN was able to submit a vehicle that did not meet the hard requirements (the 5cm gun), and still managed to win. That is some grade A favoritism.
I know I am late here, but the loon wouldn't happen to be Ernst Kniepkamp would it? I know with the half-tracks and Panzer III he was directly the guy responsible for those elements - and the Tiger I work at Henschel was also his pet project of the time.
And wait, I have Forcyk's book.... and yep it is Kneipkamp. Head of all tank projects at the Wehrmacht, and had been the chief army engineer even before the Nazi takeover when it was the "Military Automotive Department". Even the tiny Kettenkrad has the interleaved wheels, and yep the patent on that is "E. Kneipkamp".

So Rafael put out this video to celebrate 10 years of Trophy covering the past of the system.
It's pretty standard fare, but at roughly 4:15 through 4:30 - you get what appears to be the first proof of the long-mythical Merkava work with the Singaporean armed forces. That is clearly blurred SAF personnel, and the jungles that the demonstration shot was done there are exactly the flora you see in Singapore. I cannot understand Hebrew, but they flash up an image of a Merkava during that sequence, so it wasn't *just* dev work for Trophy.

I don't have my sources handy, but it's a simple thin plate of HHA spaced out by an inch or so. It mostly works on the same principles as Ye Olde Schurzen, with the high hardness steel tilting the round and forcing it to impact sideways on the base plate. And by 30mm fire, they mean the old 3UBR6 APBC, which is hardly a terrifying round.
