3.7cm PAK - Germany's Basic WWII Antitank Gun

/ forgottenweapons
Cool Forgotten Weapons merch! shop.bbtv.com/collections/forg...
Germany developed its first 37mm (or as German designations put it, 3.7cm) antitank gun in the last months of World War One; a very simple design built using barrels from obsolete Hotchkiss revolving cannons. In the mid 1920s, the concept was reinvigorated by Rheinmetall, which developed a much more modern 37mm gun using a much larger and higher-pressure case (37 x 249mm). In its initial pattern, the Tak as it was called (Tankabwerhkanone) has wooden spoke wheels and non suspension, intended for transport by horse. A small number were made for the German military (to avoid aggravating the conditions of the Treaty of Versailles), and the gun was sold commercially by Rheinmetall. The Soviet Union in particular was interested, and used the 3.7cm Tak as the basis for its later 45mm antitank gun.
Between 1934 and 1936, a number of changes were made to the design. The wooden wheels were replace with steel wheels and pneumatic rubber tires, and spring suspension was added to allow the gun to be towed at higher speed by motor vehicles. The designation also changed at the time from tank-abwehrkanone to panzer-abwehrkanone, as the new term "panzer" entered the German military parlance. Under Germany's 1930s rearmament program, the Versailles limitations were ignored, and Pak production took off. By September of 1939, the German military has some 11,200 of the guns in service. They were solid dependable guns at the beginning of World War Two, but became obsolete by 1941 as tank armor began to rapidly increase. A new tungsten-core AP round was introduced in 1940, and a rfile-grenade-like hollow charge munition (the stielgranate 41) added in 1941, but there was stopgaps at best. The last few 3.7mm Paks were built in early 1942, as both it and the 50mm Pak 38 were phased out in favor of the 75mm Pak 40 antitank gun.
There is an excellent article on the development and use of the 3.7cm Pak at Tank Archives: tankarchives.blogspot.com/2016...

9:32 Ian, that cut out is not for tracer material. It is the opening for the explosive filler. The Germans insisted that all their AP rounds had an explosive filler if possible. When you shoot a small steel projectile into a big steel box, it tends to yaw because of the massive deceleration. That will cause the projectile to spin around the tank a bit and combined with spalling, it hopefully either wounds/kills one or more crewmembers, disables critical systems that makes the tank no longer combat capable or at least convinces the tank crew that it is time to leave the tank, thus also knocking it out. This works well enough in most cases. The Germans however clearly where not satisfied with relying on spalling and the solid projectile alone. Therefore they used approximately 13 grams of Hexogen (RDX) for their 37mm PzGr shells. Think of it as shooting a hand grenade into that same steel box, but with a lot more, much larger fragments going around the tank. It isn't pleasant if you are inside the steel box...

[@DanielWW2]

​ Trebonius Flonius I can't really recommend something written down and extensively researched. Everybody who knows about German AT guns can list the 3,7cm, 5cm, 7,5cm, 8,8cm and the 12,8cm guns, but beyond that there is not a lot of information around. For example the explosive fillers I got out of a German WW2 document that is floating around on the internet which lists all the HE fillings of German shells. There also is a post WW2 US version of that. Those two differ a bit so I tend to go for the German one. Further there is the book “WW2 ballistics: Armour and Gunnery”. Long out of print, but it floats around as a PDF online. That book is extremely in depth about penetration mechanics. Finally I can defiantly recommend Military History Visualised on YT. That might actually be the best source out there on a lot of subjects. A lot of what I know is based on scraps you can gather on different forums. It really is a mess for something so crucial in understanding the war. When talking about WW2, just about everybody will quickly revert to the Sherman and T-34 production and how that "won the war". Nobody ever discusses the German perspective. The Germans produced almost 40,000 towed antitank guns during WW2, excluding the self propelled panzerjägers or captured and converted guns. That is a lot considering that AT guns usually have a distinct advantage against tanks in concealment and visibility. You can't exactly see all that well from inside a steel box. Meanwhile you can even hear tanks approaching when manning an antitank gun. If you are even somewhat competent, ranges will also have been pre plotted to allow rapid hits on targets. It extents to tactics as well. It seems that the German army didn't really evolve their defensive doctrine between the world wars. From what I know, they still relied on the WW1 era defence in depth system they tried in 1917 with the Hindenburg Line. It didn't work then against any competent opponent, and it also didn't work in 1941when facing major Soviet attacks. Standing doctrine until that point was a relativity lightly defended front line made up of infantry. The idea was to let tanks pass and pin down the infantry. Then a few hundred meters behind the infantry, the Germans would form a "PAK front". Basically a line of antitank guns to kill the tanks who were without infantry support and thus blind. I suspect that this tactic was part of the "failure" of the 3,7cm model. The Germans where responding to attacks and probably often didn't have the chance to deploy on a flank and had to deploy in front of the path of the Soviet attack. This meant facing the T-34's head on. Now even a 3,7cm PAK can penetrate a T-34's its 45mm turret front out to a few hundred meters, yes really, but the hull front is completely immune. The turret on early T-34 models however is so tiny that it is a hard target to hit reliably. Further from what I know, the Germans engaged from distances far greater than something like 200 meters. Then the 3,7cm PAK is useless. However if you get flanking shots, T-34's are in more trouble. T-34 sides are only 40mm thick and that is doable for the 3,7cm PAK. KV1's however are almost completely immune to the 3,7cm PAK. At 100 meters you might get a shot through the rear hull, but that is about it. That will destroy the engine, but if the tank doesn’t catch fire, well it is immobilised but still combat capable. When the guns fail, well the infantry has to make due. They had plenty of ideas and methods, but all are dangerous and far from ideal. See: kzbin.info/www/bejne/fKmti32cobJ4n9k Second is that I suspect that the Germans in 1941 where suffering from "Tiger panic". Basically soldiers were identifying every tank as a T-34 and mixing up the T-34 with the KV1. That would explain a lot. Even the 5cm PAK, a gun that can kill T-34’s with some ease, would struggle against a KV1. Against the 7,5cm PAK, even an up armoured KV1B stands little chance. Tactics seem to have changed during the winter of 1941 to a chequerboard system of strong points arranged in depth with interlocking fields of fire. Again the idea was to let the tanks pass to separate them from the infantry who had to attack the strong point and shoot them with the antitank guns. Another problem with that seems to be that every single German army developed its own methods with their own terminology, thus making practice anything but uniform. I suspect that might be an additional reason why so little is actually known about German WW2 antitank warfare. Really getting into this must be a nightmare to research.

@@DanielWW2 I recall somebody reviewing a PanzrJaeger memoir where the guy had to use the 3.7 on a T34 and they learned to get somebody to shoot at the tank with an HE round (a lite artillery gun or maybe a 37 mm with HE?) when the explosion would make the front hatch of t he T34 fly open; now before the driver or other crewman could pull that hatch shut the 37mm was supposed to fire into that open hatch & the resulting spalling or explosion would kill off the crew. Naturally this required allowing the T34 to get 'darned close' and head on to you to 'work properly', but somehow the guy survived to work his way up to 50mm and 75mm.

Where i live in The Netherlands the German Blitz used the 3,7cm gun to knock out bunkers our army had build in the Maas-linie and the Peel-raamstelling (2 defence lines) I can go there when i wish and see the hundreds of hits and the damage this gun can do.. Most people will think oooh its only a tiny at-gun BUT Looking in the village of Katwijk on the Maas river(Maas-line) Or the villige of Mill (peel-raamstelling) The bunkers there have 80cm reinforced concrete front walls with 20mm armour plating for a gunport (3 plates with one gunport each) for 1 light machine gun type Schwarzlose M.o8/15 and 2 riflemen with rifles from 1895!!.. The trained German crew just aimed for the small gunports and could hit it from far away out of danger from return fire and hit the gunners position with direct fire or pen the 20mm armour plate with ease..reports say sometimes at the first shot! So in fact you dont always need a 88mm gun if you can aim and are acurate! And if it could not be hit easy then how about just shoot at it 300 times, those rounds are easy to handle and fast to reload! I was amazed how deadly it could be looking at those bunkers almost 80 years later.. Lots of brave soldiers died there fighting something they could not see and a war they could not win.. They all had one order ''Standhouden'' (hold your ground) and it got them killed. I have spoken to a old mister who was part of cleaning it up after the fighting there... He is not with us anymore but i dont think he would agree with saying the 37mm pak was a peashooter. Also a fact is they used a 88mm gun on a truck/halftrack there and it was used only a few times for the most strategic places( bunkers near bridges etc) the other ones all destroyed with the 3,7cm (dozens of bunkers)

@@Keckegenkai Most tactical combat was conducted at company or battalion level, and the Germans didn't even have organic divisional 88s. Most of them belonged Luftwaffe flak units attached to infantry divisions. On the defense they were ocasionally given in small numbers to the infantry. Point is, it was pretty hard and not very common to bring an 88 into battle. The average soviet tanker did not have to worry about 88s shooting at his tank. In fact, most of the Soviet tanks destroyef during Barbarossa were overran and blown up by German infantry or motorised infantry, and were destroyed with 37mm and 50mm cannons or blown up at close range with sattle charges, grenades, mines etc. Some were destroyed by German tanks and others by attack aircraft. 88 flak guns while very effective against enemy armor troughout the war, weren't used that much for that role.

Thanks Ian! Great video. This was a perfectly serviceable weapon and effective for many jobs it was tasked with for its time. IMO this weapon illustrates the idea that reality has a way of not really caring what’s on paper. People commonly bring up armor thickness and categorical performance exclusively, when talking and comparing WW2 weaponry. This what I call the “wargaming effect” and dominates the conversation because of the countless stat comparisons in video games. It’s not a bad thing but can effect perception. In actual combat the most extraordinary things happen and with rounds hitting bolt heads, seams, optics, radiator hoses, wiring, etc. Any of these hits can be a deciding factor to take the day and that’s why, although way outdated, this thing did show up in Stürmpioneer Kompanies until the end of the war. It’s important to remind ourselves that, in each theater’s ground campaigns, as much as 85% of all target acquisitions by tanks and guns in the war were infantry or light defensive positions. These are tasks which the gun is has a practical use for. Was it outdated by 1940, over engineered, and obsolete by 41? It absolutely was, but a Kompanie would assume have it or a couple than no light AT/infantry served guns at all. Nestling these hedges, alleyways, and pulled behind or on soft-skins; It was a nice way of sending high velocity tracers, keeping the enemies heads down to buy time, if nothing else. When the gun comes up, the first thing you’ll hear about is how awful it was, but it’s important to consider the above and keep things in perspective. Thanks again!

[@Tornado15555]

I haven't had a wargame to play for a long while that has had players or is up to standard (probably the World of Tanks monopoly) but it got me into researching historical information where I can find it as a hobby. If I've learned one thing from equipment research, it's to take negative accounts with a grain of salt on just about any piece of equipment, particularly when they are widely repeated. People (myself included, if I don't watch myself) tend to bias imaginary opponent equipment in a negative light regardless of their knowledge of the subject, and that habit is of course not inherent to just equipment research! German and British tanks suffer the most in contemporary accounts, but every country takes a beating when it's time to cite the advantages of a single piece of equipment of their opponents. "Door knocker lolz" is a perfect example of that in practice, here. If all that was left for an industrializing and impressionable alien society was our wargames they would get an odd impression of what is ideal and what is not, and would probably arrive at some pretty funny designs for a while! If they played World of Tanks they'd never used tracked vehicles and would only use armoured cars with autocannons and tungsten rounds. If they played War Thunder they'd only use 150mm SPGs with HEAT and HE rounds because apparently a StPz II can kill a T-72 from the front [on a cynical note this was probably accidentally done by the developers while they were trying to legitimize the "beast killer" ISU-152] If they played WWII Online they probably would only build the Sherman because it's armour is at a uniquely American angle that allows for regular bouncing of 88mm rounds. If they played Combat Mission they probably would go with no tanks because they would be concerned that being in a tank means that training isn't applicable and that they're all death traps anyways. Thanks for the note though it is a good reminder that some are aware of more than just the sensational details that are given to them!

[@MediumRareOpinions]

@@Tornado15555 for my money one of Warthunders biggest inaccuracies is the urban tank duels. I'm not saying tanks never ventured in, but a tank roaming around a town with prepared enemy AT emplacements has a suicidal crew. I guess what I'm saying is that these games portray armor as operating alone, lacking in representation of the infantry forces they historically operated alongside.

[@Tornado15555]

@@MediumRareOpinions Well when you have a game tuned to support the patience of a fruit fly you get shorter games and it's impossible to allow to even allow for the development of additional mechanics that might, god forbid, slow the game down. Not that slow gameplay is a guarantee of realism, either! Here's a TL;DR about people tricking themselves into realism while mismanaging the land/sea/air interaction in a slower game. In Battleground Europe/WWII Online... Any lone tank, which is not modelled to use any vision ports, and has very bad MG control, tends to blow up. They say it's realistic and that all tanks were deathtraps, but ignore the fact that atgs can "beam in" at mobile spawn points, are quiet, have instant setup times, and far outnumber tanks on the strategic map. Most tanks are lost this way. Aircraft can be launched Warthunder style from an airfield 10 km away and deliver a bomb, and there are so many planes and AAA is so ineffective that players will suicide bomb. Then the devs introduce the Ju with cannons and the Hurricane with cannons! Sappers have sticky HEAT charges from the start of the campaign, and while you can avoid them if you listen for them, the game turns the derp to 1000% when dozens of bazookas and schrecks (with 100% functional fuzes) arrive late game. Bushes and foliage are everywhere, often bringing visibility to less than 200m, and bushes and foliage don't move or make noise when infantry are in them, preventing reconnaissance. To top it off, most of the fights are in cities or point blank foliage, so most of your wishes about tanks vulnerabile in urban warfare are more than granted -- tanks that already don't survive in the open are then considered less valuable than a guy sitting in a cap point with an SMG.

completely underserved for the weapon. That name was given to this weapon because it couldn't deal with the front armor of the Char 1B or the Matilda II. No standard issue AT gun in the world at the time could do that - but anything else this gun would deal with quickly and effectively, as the british got the not-so-pleasure to find out when this gun proved to be more than a match for their cruiser tanks, or the american M3s over the sands of North Africa. Not only that, it was a flexible weapon, it's ability to shoot a pretty effective HE round put it leagues ahead of the british equivalent AT gun, the 2pounder, which could not fire anything but AP rounds. That this gun was a "door knocker" against the heaviest armored tanks in 1940 should not detract from a very reliable and effective gun against anything else. Again, no standard issue AT gun at the time could do that, that's why the germans had to turn to their 88mms as "ersatz" AT guns to deal with those heavies and what kickstarted their interest into large caliber high velocity guns (that later produced the excellent 50mm, 75mm and ofc 88mm PaK guns), so that this gun couldn't do it either is hard to leverage against it, because against virtually anything else they'd face in 1939-40, it was an excellent piece.

[@albrechtbaier5239]

Dear Ian, Thanks for video! Just to be more precise - the Stielgranate 41 had two fuses: one nose fuse and one "bottom" fuse (Boden Zünder 5130), the latter was screwed in the bottom of the shell-head between itself and the tail. So it was not necessary to obtain the direct hit of the nose fuse against the armor to get the grenade exploded. According to German records and accounts this grenade was very effective in forest battles which took place during 1942 in middle sector of the Eastern Front

I use to own a PAK-184r. Which is a russian copy of a PAK-36. The story behind it was it was captured in Finland during the Winter War and still had several bullet marks from the inside. It was assumed ski troops or a flanking maneuver caught the Russians off guard and emptied sub guns from the rear into the inside of the gun. It was a de milled gun so I never had to have a DD tax stamp from the ATF for it. It was used first in re-enactments down in TX/LA where I drove to pick it up and trailered back up to me in eastern PA. Sold to fellow reenactors when I retired from the hobby and to my knowledge is still used in events here on the east coast. Use to get a lot of looks driving down the road to events. Good times.

Nope, Canadian government is afraid of small and easily concealed guns plus of course the guns the good guys and especially the bad guys use in movies.

As per usual, it was packed with features and did its specified job very well. As far as 37mm AT guns go, the PAK 37mm was easily the best on a per-unit basis. The problem, as with all German equipment, is making enough to go around and keeping them working.

@@Deilwynna It's debatable that German weapons in general actually had superior quality: poor reliability is a recurring theme.

[@TrangleC]

@@visionist7 That isn't really as much of a mentality thing as people make it out to be. German engineers too can produce simple and cheap stuff. Look at the VW Beetle. Or let me correct myself: It is a mentality thing, but not in the way non-Germans think. The mentality is not that they can't build simple machines, the mentality is that they care more about their soldiers. Germany has been a pretty egalitarian society, even in feudal times, with the elites not treating the regular people quite as shitty as in other cultures. Traditionally German officers were not as removed and not as disdainful towards the regular soldiers as they were in most armies of the time. They simply wanted to give their soldiers the best possible equipment, whenever possible. The fact that even right to the end, the Wehrmacht had surprisingly low casualty numbers, reflects that. Also there is some economic logic to it. When you are short on resources and manpower, building superior tanks and other weapons makes sense. Imagine you had a tank that is good enough to take on and defeat 5 enemy tanks, but only needs 3 times the steel and 2 times the fuel and only 1 crew instead of 5. That is a good deal and makes economic sense. You saved a lot of steel, fuel and men. That is why it is silly when so many people nowadays say the Germans were stupid because they didn't flood the battlefield with huge numbers of cheap, easy to produce tanks, like the Russians and the Americans did. That just wasn't an option for the Germans. They had trouble enough keeping their small fleet of tanks running and getting them to where they were needed. What would they have done with 5 times the number of tanks? Make 5 times longer traffic jams on their way to the front? And with what fuel? Where would the crews have come from?
