Peter was comparing the IS-2 mostly to the previous KVs in terms of weight savings since that's what he focused on in his book and articles, but other factors he left out is that German big cats had a front transmission and less transmission elements integrated in a single unit, which bloated the weight and hull size further compared to the IS-2. They also carried a greater volume of ammo in total, and if restowed could probably carry more 122mm ammo than the IS-2 could. An acceptable tradeoff for the Soviet tank given his highly specialized employment which limited ammo expenditure and gave more time to restow, compared to German tanks which were used more frequently. In fact all big cats carried an unusually high volume of ammo by WWII standards, they have both big rounds (compared to Allied 75/76 calibers in particular) and a very high quantity of ammo (70-80+). The huge 85/107mm KV projects would be closer to Tigers than the IS series in terms of total ammunition capacity and weight inefficiency.

I also want to add that the V2 had a cast aluminum block while the HL230 did not. How much this can save can be illustrated with the HL210 (little bit smaller bore, cast aluminum block, 650hp) which weights only about 1050 kg while the HL 230 (little bit bigger bore, cast grey iron block, 700hp, basically a bored out HL 210) weights at about 1300kg. Why did they switch from cast aluminum to cast grey iron blocks? Because aluminum is scarce and expensive while grey iron is readily available and cheap (from the perspective of the German armament industry). Weight saving is not just a matter of smart design, it is also important to consider situation one is in and what is actually affordable.

Exactly. Resource allocation is an important part of planning and conducting a war. Some historians even say, that had the Germans and Soviets had the same philosophy on quality/quantity in their war material. Instead of the "Trope" of Germans over engineering, and the Russians making minimum viable products, with improper quality control. The war might have had a different conclusion. Resource allocation is even an important thing in a capitalistic society, during peace time. The big difference though is, that it's mostly a question of, how much are we willing to pay for resources, rather then not being able to source them at all. Can we make a profit.

The HL230 was to become the HL234 by adding direct fuel injection thereby achieving 850-900hp. With a supercharger some 1100-1200hp was expected. These would have found themselves on the Tiger II first however it was only a matter of time they would be integrated into the Panther. That would require the replacement of the final sprocket drives with a planetary unit as on the Tiger II. (not point in adding more power if the transmission can't take it, this was planned on the slightly heavier Panther II anyway) . -The Panther Ausf F with the Tiger II like Schmalturm (narrow turret) turret allowed not only a 30% increase in Armour thickness but the fitting of the 8.8cm L71 gun. -I suspect that a panther with the Schmalturn Turret, 8.8cm L71, HL234 900hp engine, new transmission, the stabilized optics and stereoscopic range finder planed would be formidable and eventually I think might see the upper front glass increased by cm from 8cm Armour to 10cm.

Even if they switched solely to lowest quality to ensure highest possible quantity, German industry would absolutely *never* reach levels of US or Soviet output in sheer numbers, while also losing the only strength they had over adversaries, the technological one: higher protection, higher firepower, higher survivability. The biggest problems of Germans was also manpower shortage, and survivability of crews was of absolute highest priority. Not to mention that production and designing of heavy tanks, like IS-2, on side of Soviets also very distinctly shows that battles can't always be won by sheer numbers alone.

Aluminium is abundant in Russia but it’s processing was not. Germany was short of all raw materials except magnesium. Oil, tungsten in particular. Germany tried very hard to substitute (eg coal to oil) but such substitutes are very expensive. The additional iron and steel required to make synthetic fuel in Germany was equal to 25% of the tonnage of the USN.

Another factor I have seen noted is that the Red Army quickly dropped the pretense that anything made for the Great Patriotic War had to last after the war. This allowed under-building of systems with much shorter lifespans and smaller safety factors to save weight. Simple things like thinning cylinder walls in engines, replacing steel with aluminum, and such made for engines that would break down sooner, but they just planned to only run the tank less time than that. Germany, conversely, maintained full service-life requirements on most everything. A Panther made in 1943 was expected to serve the same time a Panzer IV of 1938 was intended to, so they built everything to do that even as the war went sour.

11:33 While German tanks had too many ball bearings, the design of DB605 was switched from ball bearings to plain bearings which, when combined with increasingly poor grades of lubricants, led to serious problems in service, including engine fires. (wiki) Is it just inefficient resource distribution, or just another WWII myth?
@williamzk90839 ай бұрын
The DB605 was based on the DB601 but was a new engine so trouble was to be expected. Apart from bearings, lubricants the new high pressure lube system froth the lubricants and needed to have an de-aerator added. There were also issues with alloying elements such as lack of iridium for spark plugs and lower octane fuels.. The original spark plug on the DB605A was the Bosch DW250ET 7 and this sometimes caused pre-ignition at 1.42ata MAP for the DB605A meaning the Me 109G frequently had to be restricted to 1.3 ata (atmospheres or Barr of pressure) as fuel quality was also a problem. New spark-plugs were needed to the end of the war for each increase in manifold pressure. 1.42ata - Bosch DW250ET 7/1. 1.80ata - Bosch DW250ET 7/1A and 10/1. 1.98ata - Beru F280 E43. (Driving the DB605DCM and ASCM to 2000hp) The 1.42ata capable DW250ET 7/1 sparkplug came in on the the summer of 1943 and helped to restore the original boost from 1.3 ata to 1.42 ata (10%) and also Me 109G6 speed from 387mph to 397mph (almost catching up with the 1942 Me 109G2 which did 401mph)

The engine block of the Panther and Tiger the HL 230 with 23 Liters of Displacement was over 30cm shorter compared to the giant 38 Liter W2/V2 engine. The engine compartment was significantly shorter in both german cats. By placing the transmission between Driver and Radio operator, they fruther reduced the length of the tank and gained more room in the fighting compartment. The Tigers hull was 6.31m long ( with gun 8.45m) and 3m wide (with tracks 3.54m) The IS 2s hull had a length of 6.77m long (with gun 9.83m) and was 3.07m wide. The Tiger had the bigger and better Transmission, 5 men instead of a 4 men crew. 92 rounds of main gun ammunition and almost 6000 rounds for the mgs, while IS 2 had 28 main gun rounds and just 2800 mg gun rounds, while being 46 cms longer than the Tiger. ALMOST HALF METER WHILE HAVING ONE CREW MEMBER LESS AND ONLY 1/3 OF THE AMMUNITION!!! !! The Tiger was faster, accelerated better (IS needed to stop for switching from the lower ranger to the higher range, 4 speed transmission split in low and high range) and the Tiger could endure fire fights much longer. Bernhard and Chieftain discussed the number of rounds needed on average for a successful engagement of a target during WWII. They said depending on the range bewteen 5 to 10 rounds were needed. So German, US and British Tanks both carried between 70 and 90 Shells in general. The outliner were the soviets in this case with 28 shells. Just look at m26 or Centurion. Given that the accuracy of the 122mm gun was similar to the short 88, the number of targets witch could be enganged with just 28 shells is rather low. At to that the massive gun overhang of 122mm, because the turret is sifted forward while the transmission was put in in the back. A center mounted turret was not possible because of taht. It further reduced the IS2 to safely clear steep crests, ditches, trenches and hills aswell as towns and trees. Add to that the poor gun depression of just - 3°, which is just 1/3 of what tanks should have. The hull mg gunner is also essential for suppressing enemy infantry and At-teams on the move, because the main gun and the coax MG did not had a stabilizer. The IS2 did not had that ability. One of the biggest issues of the T64 were its light weight and small roadwheels. All other Russian T tanks had big roadwheels, just like the German cats or the Centurion, Comets or pretty much every modern tank. But now I should buy the fact, that the small roadwheels of the IS2 were a great idea? When every physical aspect, like rolling resistance, clearing gaps, climbing obsticals and ground contact area are in favor of big wheels. Or even better big and many wheels. Small and fewer wheels is the exact opposite I you should aim for. T64 being the bad example! T72 the good example! Furthermore the rate of fire 2 Additionally the rate of fire. IS2: 2 to 3 rounds a minute, Tiger 8 rounds a minute. The IS2 only had better armor protection for a given weight and a lower profile by few centimeters going for it. Every other important aspect of making a tank effective in combat, was put to a disadvantage by the two advantages it offered. And all that is sold to me as a great and superior design compared to western tanks. Sorry I don't buy that. Even IS3 performed miserable against Israel using western tanks, for the exact same reasons. M48 was also 2 tons heavier while offering less armor protection. Peters approach is confusing and wrong on so many levels...

Technically, M3 was not the starting point for M4. Rather, M3 and M4 Medium tanks were concurrently developed from the Medium Tank M2 and other armored vehicles of the US Army. M3 Medium was developed because it was identified that it would take around two years to properly develop the turret to mount a 75mm gun, while a hull-mounted 75mm system could done within about a year. Thus, Medium Tanks M3 and M4 were both green-lit for development within a few weeks of each other, but M3 was expected to enter production ideally a year sooner than M4 and to only serve while M4 remained incomplete. This is one reason the original US Army order was only for a few hundred M3s, enough to arm the planned armored divisions of the still-at-peace US Army in 1941, and it is mostly the demand from the British Empire and USSR that saw the production rise to the thousands in the end. Now, experience from M3 was used to inform M4 development, but M4 nonetheless was not a direct result of M3.

The Panther went from drawing board to production in 12 months and first delivery in 15 months. I suspect any extra 3-6 months would have removed most of the bugs of the tank. The early engine fires came from a leaky perforus fuel hose and the fact that the engine was placed in a sort of aquarium to allow deep river crossings. This also caused cooling problems. Though quickly fixed the engine fire problems is still used against the Panther to this day. The only other major problem was the weakness of the two final drive reducer gear boxes that drove the sprockets. These were simple straight cut pinion and main gear rather than planetary (as in Tiger and T-34) or Herringbone (as in Sherman) needed in this position.
@no-legjohnny36919 ай бұрын
@@williamzk9083 Regarding the engine fires, it could potentially have something to do with the gasoline fuel they used. The flashpoint for gas is very low, so fumes could build up and leak, potentially catching fire from a spark of the exhaust. Although I think the more likely culprit was the engine itself, because such a large engine typically requires strong cooling, but as you mentioned, they don't get adequate amounts and tend to overheat. Since engines can get hot enough to cook an egg even with proper cooling, it's possible that the rubber fuel lines could melt and cause a fuel leak in the engine compartment. Because as far as I'm aware, engine fires were rather prevalent on not just panthers, but all of the big cats in general.

The Tiger 1 actually had better front turret armor than the IS-2. Effective 140-225+ mm (90-150mm mantlet, where all thicknesses 125mm and less were backed up by heavy bars of 100mm turret armor ). There are drawings online. The IS-2 had only 100-115mm front turret armor. There's a picture of one IS-2 that has a clean turret penetration, performed from 2600 meters from a Nashorn, but even a Tiger 1 or Panther could penetrate the front turret at normal combat ranges.

It looked great on paper, but nearly always underperformed in combat. It was blind like the T-34, and the two piece ammo was a disaster in practical terms: The tank was filled with smoke after one round, and the dust kicked up outside blinded it further for minutes on end... The IS-3 looked even better on paper, and was, in theory, world class right up to the 1970s, but it was in fact even worse... In actual combat performance, the IS-2 was little better than the T-34, and far below a Panther or Tiger. The Russian SP guns probably did better against German armour just because of better internal space, lower silhouette and one piece rounds.

My understanding is that this was tested on IS-2 using either the same gun or a derivative of the BS-3 AT gun or D-10 as was used on the SU-100. The tests were considered successful but production of a 100mm IS-2 was not pursued because the big 122mm gun was more effective for the intended use of a breakthrough tank - basically hit something as hard as possible, not necessarily as fast as possible. If IS-2 had been intended for a more strictly anti-tank role they probably would have used that gun on it, but that ended up going to the SU-100.

@@tiagodagostini Read from people with actual first hand experience with the IS-2. It was a serviceable bunker buster, but not very useable versus other tanks. The KT had a superior kill ratio to the Tiger I, at a much lower production cost. At 485 built, it hardly got out of what was the test phase production of other tanks. It did tend to jam one drive sprocket with close range glacis hits, which was a flaw, but those hits would have pulverized all other tanks anyway... As to vision, the German cupola was a perfect design for protected 360 degree vision, and a massive German tank advantage. So much so, the Germans even welded those cuppolas on captured T-34.

I kind of think this sounds like stats-hunting. yes they increase the Armour and decrease the weight. This makes pretty much all the stats much better. Of cause, lower weight is better if they dont sacrifice anything. And of cause just doing good work will help. But it sounds like they actually sacrifices features. Of cause removing the radio operator for instance saves literal tons of weight (due to the hull being narrower). But well, there is a reason why Germans tanks did have radio operators. Stuff like general crew protection, ergonomics, reliability. Now i have not seen a IS-2 in real life, but a T34 is really quite cramped on the inside to the degree that it hampers the work of the crew. This of cause make the tanks smaller, in turn making it lighter. But you then have to ask if you making it lighter or having thicker armor, becasue you making the tank better or because you hunting a stat. Gun depression - 3 for IS-2 -8 for tiger. Lower gun depression allow the roof of the tank to be lower and flatter, decreasing weight or increasing Armour. But again, having gun depression is very useful. This is the diffrance from firing behind a ridge and firing on the ridge. It don´t matter if you have 120mm armor compare to say 60, if you have to expose the whole tank every time you fire. Tiger could carry 80 shells, IS-2 28. Again, that makes it possible to make the tank smaller. Casted Armour allow for more armor flexibility, again allowing for less weight or more armor. But again, its a compromise. Germans didn´t have forged armor because they didn´t know about casted. They had it due to quality and quality control. One could of cause argue that the German panzers was sort of overbuilt in this regards. But the quality over quantity made great sense considering lack of fuel. By the point in mid 1944 when the IS-2 actually engage the Germans, its questionable if it even made a diffrance anymore. And to be really clear, the question is if its ever did. Tank on tank combat is very rare. Outside the battle of kursk there been very few large scale tank on tank engagement. I´m not saying tanks are useless. But my point is, making a tank specifically for taking out other tanks may not be the best aproch. There is a reason why a lot of countries use special tank killers
@czwarty78789 ай бұрын
This is true and it's really annoying how it's almost never brought up. This is approach that stayed like this to this day in modern tanks, and there was a reason why both German, as well as US and British tanks were "too tall" and bigger than Soviet ones. Taking into account only armor, weight and size is video game style of assesment. Amount of carried ammo, fuel, equipment, radio, visibility (visors, periscopes etc) and space and ventilation allowing crew functioning on consistent level for prolonged time were just as important and remain even more important to this day. I can tell you that your prediction on IS-2 is accurate, and in fact it's even worse than T-34 due to the massive gun than this tank was not exactly optimised to handle. I saw inside of IS-2 and had privilege of talking to crewmen of that tank (both during war and in 1950s), what they always recalled was that after firing the gun the inside was filling with toxic smoke due to insufficient ventilation, while outside a huge cloud of gasses raised up creating basically a smoke screen - cutting off visibility of the gunner. So the RoF was further limited not only by mass of shells and increasing fatigue of loader, but also filling the inside with gasses and smoke outside which had to diffuse. Therefore this tank was not able to observe target after firing and make corrections for follow-up shot, observe the damage or even see at all if target was hit, not to mention to carry out prolonged fire, shelling, or participating in longer tank battles. The crew also had to limit RoF further than what speed of reload would allow for so the gasses dissipate. So IS-2 was more of a turreted assault gun, good enough for shelling stationary employments, bunkers and installations, while remaining safe due to it's armor, but it was not able to keep up with normal tanks in armored battles or rapidly changing environment. Therefore it can not be compared to Panther, Tiger or M26 which were much more universal and consistent designs. So yeah, experiencing this issue makes it very clear why western tanks were so much bigger - they were structured to employ actual proper ventilation, observation equipment, high ammo allocation and radio, and were actually spacious enough to not negatively affect crews during ongoing battles. So much more important aspects than what video game "hard stats" set would suggest.

This is great but did you do any investigations on Panther/Tiger/King tiger Vs IS-2 tank engagements? Design is great until it gets into battle.

Germans would try to avoid the thing entirely, so that should mean something.

Well, the if we just look at losses, it can seem that tigers were better. But in fact, in that moment, soviets were attacking, what means much harder job for their tanks. IS-2 and Tiger 2 are close to equal opponents. But IS-2 was much more reliable, was lighter and had bigger gun. Soviets were good at understanding why do they need tanks. IS-2 was effective against infantry and heavy fortifications (in the combined battle, where infantry, tanks and aviation have important roles). German, in opposite, created masterpieces, that suited to their late-ww2 strategy - lone hunter planes and defending the positions

Smaller inside, hauling 122 shells around. I'm betting RoF and crew ergonomics were the tradeoff.

Less shells I think, plus transmission layout wasn't weird. Iirc Germany needed a certain amount of shells in each tank and that didn't go down as shells got bigger

plus less comfort for the crew and harsher requirements for recruitment of tankers. Best tanker was 150 cm tall, anybody taller 170 was prohibited from recruitment as tanker. Thats why Chieftain youtuber always have a troubles stucking in soviet tanks with his enourmous for proper tanker height

And not to mention EXCELLENT situational awareness, it had two 360 periscopes for both the commander and gunner, whereas in German tanks the gunner only had their telescopic sight and thus was blind

They’d learned from harsh experience a tank doesn’t last long in high threat areas. Regiments of tanks get swallowed up and made ineffective from losses so making them good enough to last a few hard hours and days is enough. Your factories make many thousands more. They made the IS-2 hard enough to take it and allow crews to survive, lesson learnt from the T34 and the fire casualties they had. Soviets weren’t that bad at looking after their folks.

As much as i hate the soviets does not mean ill discredit them as the Is 2 was very much better than the Tiger 1 and two with the IS 2 beating the Tiger 1 in hard factors and beating both the Tiger 1 and 2 in hard factors.

I wish computer programmers and also their bosses do really think not once but twice and more deeply on the pros and cons of their designs and their overall decissions. My life as QA would be easier: Leave the job they gave me because I think too much about the work we do and do it myself again as it should be done: Thinking better to do it better. But that will never happen because our profession is getting cheaper and cheaper, so nobody cares about good work, just about selling half cooked systems that will need a lot of manteinance which will have to be sold in the future. This is not the way we will reach the stars. We will instead get bogged in thick mud as the next fossils in the paleontological record.
