  • The Panzer IV 75mm (short) and the T-34s 76mm were quite different in 1941, yet was the general concept so much different? How did the guns develop over the course of the war? Also what were the benefits of the 75L24 gun?
    In this video with Dr. Jens Wehner, we talk about how the Germans and Soviet approached their tank guns. For this we look at some objects from Military History Museum of the Bundeswehr in Dresden permanent exhibition. Additionally, we have some footage from the Panzermuseum Munster.

    the advantage of low velocity guns is that, since you have less pressure in the gun, you dont have to make the projectile casing as thick. Hence you can fit more explosive charge in your round for the same caliber

    • @bezimienny_andzej6425
      @bezimienny_andzej6425 Месяц назад

      Germans pretty much used lower charge for most of their HE throughout the war, with lone exceptions like Tiger's cannon, f.e. Panther's AP went like 900m/s and HE only 700. Kwk 40: AP went 750-740, HE - 550m/s. So it wasn't that much of a problem to make a thinner walled HE for "high velocity cannons", also 7.5cm KwK 37 actually had a smaller filler than the HE round used in kwk 40 or kwk 42.
      Low velocity guns were good because their ammo was way more compact, easier to handle and you could carry more. The cannons themselves were also were smaller and lighter as a general rule.

    Jens is right that there was a small batch of T-34/57 toward the last quarter of 1941. There also was another small batch issued mid 1943. The difference was that the early batch only had AP ammunition available, but the later batch had APBC ammunition, which had better long-range ballistics.

      The 57mm was put in the T34 to have an anti tank gun with proper penetration in the T34. They stopped the production because the effects on the target were not satisfing. It took serval shots to take out a Pz.IV. When the tiger entered the battlefield the 75mm was unable to penetrate on most practical ranges, so they again produced a batch of T34 with 57mm. But at that stage that knew that the T34/85 was coming soon.

      @@KilledMind1985 Doesn't sound very plausible. They abondaned the 57mm against the Pz IV but then bring it back against the Tiger which was a very rare tank to begin with?
      I think the general believe why they didn't produce them in large numbers was because the 76mm was a multi-purpose gun and more effective vs soft targets than the uncommon tank targets.
      The article from Peters tankarchives might also have information about that. I remember vaguely something about not having scopes for the 57mm gun to mount in the tank.

      @@KilledMind1985 Innitially 57mm ZiS-2 anti-tank gun entered production in 1941, but production was put on hold after 370 guns, because their production lines could be used for 76mm ZiS-3 which could kill tanks just as well, while being superior in every other way. ZiS-2 was also much more expensive than lighter 45mm ATs, that could still do their jobs adequately. Production of gun restarted in June 1943, when 45mm became clearly obsolete, but was still rather limited compared to 76mm universal guns. When second attempt at fitting 57mm on T-34s was made, it wasn't as much battlefield requirements, as sudden availability of guns so they can be put to test.
      57mm also had short barrel life, which is acceptable for anti-tank gun, but pretty damning for any other job.

    • @Sapoman2211
      @Sapoman2211 2 года назад +2

      The 57 was desired only because a smaller, very fast projectile would have better penetration, even though the explosive inside would be smaller. With a 76.2, you're generally killing the crew or crippling the tank with a single penetration. With the 57, a shot through the front might leave enough of the turret crew alive to continue firing, and the extra penetration was unneeded. When tigers and panthers came out, the 76.2 was insufficient. It doesn't matter how much damage your shell does on penetration if it can't get through, and you can't just say "well, the enemy doesn't have many of those tanks" and leave your divisions helpless.

      Only in terms of subcaliber munitions relying on tungsten. Their general AP projectiles actually improved all the way till the end, as they didn't lack any materials to make these, and also came up with better metallurgical compositions and heat treatment processes here than the Allies did. Comparative testing of German and Allied AP projectiles at the Aberdeen Proving Grounds immediately postwar would reveal this. The problem the Germans had with armour production in the end was a periodic lack of key resources to make the armour sufficiently ductile, which resulted in brittle plates susceptible to cracking upon being hit. That said it was a problem plaguing certain batches of tanks produced, i.e. not all tanks, some were still being produced with sufficiently ductile armour even at the end. For instance US conducted tests on captured Panthers found that on the late war vehicles it was basically a 50/50 on wether the armour was up to usual German specs or not.

    • @KilledMind1985
      @KilledMind1985 2 года назад +2

      Shortages in materials effect tanks guns a lot. Tungsten core ammunition is only one of the examples. The penetration of went down from Panzergranate 39 to Panzergranate 41. The 5cm KwK was not capable anymore keeping up because without tungsten core ammo there was not enough penetration.
      Than there is the weight of the gun. Stronger metals in guns usually ment that a bigger gun could be placed in a smaller turret, best example there is the 75mm in the m24 chaffee.

    13:30 Well, the German Sturmartillerie did take the Sturmhaubitze 42 in service with the 105mm howitzer. A vehicle that fired a large HE round and in a greater arc than the long 75. So that version could definitely cover the original role of the StuG.
    The high muzzle velocity of for example the long 50mm L/60 creates a better armour penetration but makes it also easier to hit moving targets.
    The short 75mm has decent armour penetration, especially with HEAT, but hitting targets at a longer distance is more difficult due to the longer flight time of the projectile and the greater arc. Early StuG's and Panzer IV's did fight tanks succesfully but usually at very short ranges, less than 200 - 300 meters.

    There's one thing that always impressed me: the Soviets always managed to put in bigger guns than the Germans.
    Panther: 75mm; T34: 85mm
    Jagdtpanther: 88mm; Su: 100mm; 122mm; 152mm
    Tiger: 88mm; IS2: 122mm
    Also, if you think of how frigging big the turret of the Maus was to carry the 128mm and how comparatively small modern tank turrets are despite even higher power. Especially the Soviet tank turrets are so frigging tiny that I have no idea how they manage the recoil dampening (both in space available for recoil, but also where to put the recoil dampener system in such a small turret)

      Recoil eh. Well there are two ways to do it. Put strong pneumatic/hydraulic recuperaters on the gun to absorb the shock. Or strap the gun directly to the chassis and let the vehicle suspension absorb the shock. The Soviets would use a little of both.

    • @graemes813
      @graemes813 2 года назад +44

      Hmmm - yes - the Soviets had some bigger calibre guns but these were not necessarily more powerful than the German guns. The Panther's long 75mm was an exceptionally potent and accurate anti-tank gun. It was, if I'm not mistaken, a more powerful gun in that role than the Soviet 85mm. Both the longer and shorter versions of the 88mm in the two Tigers were also formidable anti-tank guns until the end of the war, and the long 88mm on the Tiger B was a particularly huge gun that used a massive cartridge case. The larger calibre gunned Soviet vehicles, on the other hand, were not always ideal to use against other armoured vehicles, although they could do that too if required, but they sure could demolish buildings and fortifications. Even the 122mm of the IS 2 had problems in the anti-tank role. It's separate loading rounds were slow to reload and not much ammunition could be carried. If I'm not mistaken, the German 88mm were also more accurate at range. But those big Soviet 122mm and 155mm guns were very suited to destroying fortifications with direct fire and that's what they were apparently mostly called on to do.
      So it's not necessarily all about gun calibre.

      The figure I remember from his earlier book -- The Design and Development of Armored Fighting Vehicles 1939--1965 -- gave a ballpark figure for a 'generic' shaped charge as being 4.5x the diameter of the charge, but this was dependent on the charge detonating at a sufficient standoff distance to allow the metal jet to form properly, which none of the WWII shaped-charge warheads had. One of the best examples of design changes for improved standoff is comparing the TOW missile variants, from the original BGM-71 to the BGM-71B with its extending probe to detonate the warhead at a proper standoff distance.

      The length in proportion to the diameter gives a better information about the ballistic characteristics of a gun.
      Nowerdays it gets confused a lot with the way it's used in handguns. In handguns .cal 45 is of course 0.45 inches.
      In artillery it's 45*diameter.
      Caliber is always defined by the diameter of the bore of a gun. 6"/50 for example is a naval cannon of 6 inches in diameter, that is 50 calibers long. So 50*6" = 300" = 7.62 meters.

    One consideration for selection of barrel length is ammunition commonality with other artillery in service. Once the Soviets decided on 76.2 mm cannon (for mass of shell) there was a choice of the 76.2 mm M1902 (& upgrades), the 76.2 mm 1927 Regt'l gun or some "mountain" of 76.2 mm caliber. Once the choice fell on the standard 76.2x385R mm of the field artillery a barrel length of less than the 1902's L/30 could lead to undesirable effects such as excessive muzzle flash. The US Army chose a L/28.4 barrel length for it's first 75 mn tank cannon (the M2) which chambered the same basic ammunition as the 75 mm field gun L/28.4 M1917. Pity the Nazi logisticians who had to supply different 7.5 cm ammunition for a variety of 7.5 cm weapons - 7.5 cm mountain gun, the field guns lFK 16 & N/A, lFK 18 and the 7.5 cm KwK 37 which all used similar sized (length & rim/base diameters) plus a plethora of "Beute" guns looted from occupied countries (albeit many were similar pre-WW I Krupp 75 mm or French M1897s). At least there was some compelling reason for the75 mm KwK 40 & KwK 42 fir having different ammunition.

      The question is not how far can it shoot with HEAT but what is the effective range to hit a tank sized target under combat conditions. The answer to that is: itdepends.
      Most likely the effective range is in the 500 m ballpark. Concidering the v0 is ~450 m/s. The HEAT rounds also where not know for accuracy and they had rather erratic performance.
      "The 45mm gun of the Soviets was also quite good and similar to the 76mm in philosophy."
      Actually the 45 mm guns where quite bad in reality. They usually where of rather poor quality. With poor optics and laying equipment. In addion the poor ammo. Its ballistic performance is only slightly better than that of the 37 mm guns. The small HE shell is very poor and this is very important for AFV use. The 45 mm guns where basically the same as the German 37 mm weapons performance wise. Only the German guns where much more accurate and the munition was reliable. The 45 mm guns are a good example of a paper tiger. The stats look good on paper but in reality the difference to their smaller kin is to little to matter.
      The 75 cm KwK 37 and the Soviet 76 mm where much better all round weapons. With adequate performance against armored targets and very good perfornance with HE. It made as little sense to use the 45 mm for the Soviet as it made for the Germans to use the 37 mm on their tanks.
      "It seems to have helped a lot during the Khalkhin Gol battles against the Japanese."

    That was a really good point, a low-velocity gun is better at shooting over friendly infantry. But I wonder why they didn't just use HE-shells with less propellant for that, similar to how modern artillery uses shells with varying amounts of propellant based on the range of their target

      I think there is a limit.
      If your gun is made to fire high velocity AP shells then you can’t lower the muzzle velocity of HE too much or the gun won’t operate with the reduced recoil.
      At least that’s what I feel like might be the reason.

      Low velocity HE shells have two advantages.
      1. They have bigger fragment dispersion.

      The higher the impact angle and the lower the velocity is, the more fragments will be send around the shell instead of just hitting the ground.

    There are definitely times when plunging fire is more useful than direct. I may be mistaken, but I think that is what hurt the Hood in the battle with Bismarck, engaging at extreme range where the shells have a higher arch. Like tanks, early pillboxes and other fortified positions might have thicker walls than roofs. This would also be good with air-burst rounds, but I have no idea if those were available.

      The Hood issue has a lot of debate around it but the range when she was hit was not extremely high for battleship guns (18,210 yards) and the angle of fall at this range would be around 13°. I think the most likely cause is simply that Bismarck shot straight through Hoods armor belt. This would have been possible at this range if Hood was at least half way through her port turn and the wreck of Hood has the rudder in position to be making this turn. It's also possible a shell passed below the water line and missed the belt entirely.

    Ha! Another naval counterpart, this time to the lesser muzzle velocity leading to better indirect fire because shells could be directed over friendly troops easier. Battleship ammunition was separate shells and charges, with the Iowa class using six 50 kg bags (memory nay be off). For shore bombardment, they used fewer bags to reduce barrel erosion, but I don't remember how many or whether they ever used just one bag. Tank ammunition is small enough to be a complete round of charge + shell. I wonder if any land artillery ever uses reduced charges, whether to prolong barrel life or to get higher trajectories for better indirect fire. (I am a raw rookie as far as armies go)

      It's fairly common for mortars to have augmentation charges -- a bagged split ring of propellant that fits around the shaft of the mortar round to add to the weapon's range. For example, the British 81mm L16 mortar with just the base charge has a range of 170-520m, but with the maximum of six augmentation charges has a range of 1700-5680m. Some field artillery is similarly configured to use varying numbers of propellant charges -- the US 155mm howitzer uses four-part ammunition, with separate fuze, projectile, propellant, and primer, with different quantities of propellant (either different-size single bags or different numbers of 'modular' propellant charges.

    Yes I know they do briefly mention this but i'll be a little more exact. At the end of 1941 the Soviets had the longer barrel 76mm gun shown here but before that they went thru some very short barrels. I believe the original T-34 gun barrel, probably the one the first Wehrmacht units would have encountered would have been in 30..5 calibers long or 76.2 mm x 30.5 mm = 2324 mm or 91.5 inches long ( about 7-1/2 feet) so it wasn't actually much longer than the short stubby german 75mm 24 caliber gun. The real difference was that the early war 75mm guns were meant for high explosive work and had very very slow velocities while the russian gun was already more of a anti armor weapon but of course it too had an effective high explosive charge.

      There’s only so much a few tanks can do but, if you overrun the enemy with a great number of tanks and cut off their supply of fuel and ammo, even the best tanks turns into worthless piles of junk.

    Very good, thank you. I have read that the HEAT ammunition for the German 75mm L/24 kurz was subject to improvement during the war. So it got to the point that that the Germans figured that they should use the gun to replace the 50mm L/60 gun on the Panzer III, which had acceptable anti-tank capability but a poor HE round. Hence the Panzer III Ausf N, the last of the Panzer III models, being equipped with 75mm kurz. Interesting that some of these Panzer IIIs were integrated into some of the heavy tank battalions, which had no integrated infantry, at Kursk and in Tunisia. I am not sure how well that arrangement between Panzer III N and Tiger worked, but it doesn't seem that it lasted very long. Maybe an interesting subject for a future video? 🙂 From pictures, it would seem that the German army in Norway ended up with quite a few Panzer III Ausf Ns and, if I'm not mistaken, some were used for training purposes.

    It is often forgotten that the Panzer IV was originally made as an assault-support tank for the Panzer Grenadier units. Seeing that it would be demanded by normal infantry to support their troops. Seeing this demand brought about the development of the STuG series of assault tank for the infantry divisions. However as history unfolded all this became very blurred. Finally leading to the Panzer IV swapping roles with the Panzer III with the P4 model F2.
    Barrel length impacts on round velocity. Basically the longer the barrel the faster the round as it leaves the barrel. This impacts on high explosive rounds. Again basically the faster the HE round is the thicker its casing must be to prevent the casing from breaking up mid flight. This means you lose more of the internal space for explosive. An example can be found with the Sherman tank. The preferred version was the 75mm gun over the 76.2mm gun in the armoured divisions by the troops.
    The high velocity 76.2mm tank gun when firing its HE round had to have a much thicker outer casing to the point where it was less than half effective as the round fired by the lower velocity 75mm gun. On the other side of the argument the longer the barrel generally an increase in armour penetration of an armour piecing round.
    So I propose your comparing apples and oranges. Both guns were developed and optimise for two different purposes. The German 75mm is optimise for high explosive rounds for devastating exposed infantry, light bunkers and or light AFVs. The Russian 76.2mm on the other hand had higher velocity and optimised for main AFVs while being less effective in HE work that the German 75mm was optimise for.
    It was quite an interesting video providing much thought. Perhaps a comparison between this model of 76.2mm with the long 5cm of the Panzer III. However the types of rounds fired by these guns must be considered for a more complete and better comparison.

And also developments in face-hardening armor, etc.). But, and this is a very big but, just because it is possible to build a "thin shelled" high capacity HE shell, this doesn't mean it is practical to do so at the large scale. Speciality steels also tend to be very very expensive steels, and consequently in short supply. And the one thing you absolutely do not want to be in short supply in a land war is HE shells for you most common artillery pieces... So in general, thinner shell casings do indeed mean lower muzzle velocities, and vice versa. Yes, there are exceptions to this as you note - but that is the general trend.

This is all to say good weapons come after politicians fail to keep the arguments in the halls of the UN or League of Nations then. Dont take this as support of detante, deescalation, or appeasement. To reign in an opponent create alliances that would make conflict suicide only for the opponent. So not support of MAD either. I believe politicians need to be dynamic, bold, and productive.

    I'm surprised ,with everyone being cash-strapped in the 30s, that they kept making different guns for special purposes instead of a gun and different shells for all the special purposes. Even then the rounds you hunt wolves with was different than what you hunted deer with. So the same rifle would do both and your bullet weights were simply different. I could definitely see for infantry support a vehicle with a true high angle howitzer mounted to get indirect fire. You could even adjust the velocity by adjusting the powder charge and burn rate so the AP is faster and the HE is slower and lobbed more.
    I know the history and they didn't , it just seems odd to me.

      In 30's (and in WWII, and even today - if we count IFVs as light tanks) you could kill a tank with a rifle, so giving an anti-tank gun crew a 76 mm cannon would not be only an overkill but also would harm their mobility (45 mm cannon is twice as light as 76 mm one - 540 kilos vs 1200).
      And, of course, you can't make proper artillery with two inches of a caliber and round speeds making indirect fire impossible.

    It got worse in 1944 due to loss of critical ores needed to improve toughness and disruptions due to bombing, but the Germans had issues with brittle armor from day 1.
    I’ve seen tests done by UK, and USSR as early as 1940-42 on Pz1- Pz4, Stugs, and armored cars that revealed significant cracking and spalling due to over-hardened armor on SOME vehicles. It’s clearly evident in many photos with the same ammo and firing conditions that some rounds failed to pen or made clean holes and other hits broke huge chunks of armor out even in vehicles made in the same timeframe. The issue was not consistent and varied a lot from one vehicle to the next. May be partly an issue with some mills using improper quenching or other QC issues while other mills did better. Plates were made in several places even on the same vehicle model. Even at the end some plates were very good quality while others were bad.

    • @kimjanek646
      @kimjanek646 2 года назад

      That’s not really true.
      German plate hardness depended on plate thickness and thickness determined protection against different calibers.
      High hardness has the best protection when the armor is thicker than caliber but the opposite is true when the shell overmatches the armor.
      30mm high hardness plate offered protection against calibers up to 20mm.
      If you shoot does plates with 40 or 45mm guns, they will easily shatter but even the best 30mm armor won’t stop those larger rounds anyway. Soft 30mm armor on the other hand can be easily defeated by 20mm cannons or AT rifles.
      The Polish were able to take out early Pz IVs from the side with 20mm AT rifles, because they only had 15mm of armor on the sides. The Pz. III had 30mm all around, making them practically immune against them.
