Experienced anti-tank gun M-75 107-mm

According to the Decree of the Council of People's Commissars of the USSR and the Central Committee of the CPSU (b) of 172 in May, 14, No. ПХNUMX / 1941, produced a prototype of an anti-tank cannon of caliber 32 mm. In the manufacture of used carriage 116-millimeter howitzer gun model 107 year.

In the spring of 1941, the Perm designers under the leadership of S. Dernova. was designed anti-tank gun M-75. They designed a wedge semi-automatic shutter. The calculated penetrability at a distance of 1000 m at an angle of 30 degrees was 165 mm. At the beginning of the Second World War, plant No. XXUMX produced two prototypes of the M-172, which were then tested at the factory site.







In the period from November 29 1941 to January 12, 1942, the ground testing of the gun and its ammunition was carried out at the Tagil test site.

During the tests, the ballistics specified by the tactical and technical requirements were achieved. The initial velocity of the projectile was 1020 meters per second. However, armor penetration (specified in 160 mm) was not provided due to the fragility of the shell of the shell.

The X-NUMX-millimeter anti-tank gun M-107, according to the conclusion of the Artillery Committee of the KAU, of the ground tests, did not withstand the unsatisfactory performance and durability of the actions of the semiautomatic and the valve, the insufficient pipe durability and the insufficient strength of the cradle.

According to the Deputy People’s Commissar of Defense of the USSR, Colonel-General of Artillery Voronov, since the experience of modern warfare did not confirm the need to use such weapons to combat tanks enemy, the further development of the anti-tank gun "M-75", as well as the ammunition to it in order to eliminate the identified shortcomings was inappropriate.

It was in connection with this that Voronov asked Stalin for permission to stop work on the X-NUMX-millimeter anti-gun M-107. In addition, he requested to stop similar work on the 75- and 85-millimeter cannons "ZIS-107" and "ZIS-23" at the State Order of Lenin Plant No. 24 named after Stalin.

    According to the Deputy People’s Commissar of Defense of the USSR Colonel-General Artillery Voronov, since the experience of modern war did not confirm the need to use such weapons to fight enemy tanks, further refinement of the M-75 anti-tank cannon, as well as ammunition for it, to eliminate the identified deficiencies was inappropriate.

    How wrong you were, Comrade Future Marshal .... I think in '43 you understood this .... Oh, how would such systems be useful both as a fire protection system and for installation on self-propelled guns and tanks ...

      The freed up resources went to the hundreds of tools needed then. So the decision still had a considerable positive role. I think that in the year 41, such decisions largely influenced the current situation, and were the only correct ones. On the other hand, as soon as the situation at the front leveled out, it was necessary to unfreeze high-power gun projects.

    Dododo, it's easy to argue from the couch in 2013 that someone is wrong there.
    and nothing
    -that there are no goals for her and the tiger didn’t even lie on the neutral,
    - that it is worth a lot to load the industry at this time, and invest in it.
    -that after a shot it’s only to be pulled by a Komsomol member (remember who else had it?), and the dimensions nullify the mask
    -You can pump up the caliber and ZIS-2
    Well, cool, spend a lot of money, money and time to have a gun that penetrates 163 mm at 1 km, it looks like a shed, while the armor of 4 is half (if not a third), and this despite the fact that commonplace BBs to F22 crumbled from poor quality of hardening, although like 45 they should have punched up to 1 km, and there were no sub-calibers and godfathers in nature, although they should be stamped according to plans.
    You can still do Kruchevsky’s cannon, the time and money in the country in 42 was in bulk ...
    how such systems would then come in handy as both anti-tank systems and for installation on self-propelled guns and tanks.

    what kind of sau do you offer this fool?
    Which tank? Do you want to steal the mouse from the Germans?
    and what was bad D-5? ZIS-2? D-25T? ML-20?

    Conclusion - no matter how difficult the country is, one should always think for the future ...

    thought otherwise we would not have

      and which one is an adequate response to a tiger cannon?
      d-5 is weak.
      3 from a small thing + short-lived trunk. Do you need to explain that 57mm land mine can never be compared with 88mm in power?
      D25 inferior in rate of fire, although the projectile is more powerful
      ml20 is not anti-tank at all. its pillboxes to destroy and all

      so at the end of the war began experiments with 100mm guns for the t44. I don’t remember there were attempts for the 34-k (there was no place)

        since when has the main criterion for evaluating the anti-tank gun become its comparison with the enemy’s tank gun?
        In general, the armor and iptap were engaged in this.
        well let’s down, let's put them on the self-propelled guns
        Then, why did you decide that the 107-mm gun is suitable?
        if she never hit a tiger from 7 shells? But he won’t wait in life

        ml20 is not anti-tank at all. its pillboxes to destroy and all

        true, but the Pasans didn’t know ...
        HE shells of the ML20 cannon, when hit in the wall, destroys the welds of the frontal part of the tank and destroys the transmission.
        The ML20 VL gun’s BB shell doesn’t penetrate; when hit in an NLL, it makes a hole less than a caliber and breaches the armor

          ogogo. in general, the guns are connected, an example based on the anti-aircraft guns of the tiger guns and t34-85. ml20 put on a self-propelled gun. as well as is2 and isu122 with its source ...

          so directly there seems to be no connection, but ... it is clearly traceable. recall su100 based on a sea cannon ... so that there was no one to fight with the tiger either (pto) and there was also nothing to transmit to the tank — convulsive searches. time delay - spilled blood at the front.
          the automatic machine, too, the sandpiper said unnecessary. and zis3 unnecessary! but in the end?

            Well, what's the connection? I didn’t catch it.
            I understand the divisions, or the concept of universalism, where else it didn’t go.

            but for a gun, it doesn’t matter what’s on the enemy’s tank, 5 cm kwk or 8 cm kwk, the Iptapovets’s defense mother is cheese, his earth, ingenuity and speed of reaction, stealth, rate of fire, the lower the better, and so on.
            It is not for nothing that I remembered Heinz's phrase about "barn gates", look at all the pto, low, light, to change the position, quickly deploy, etc.
            and look at Pak 43, here's an example of what could be with m75

            m75 is a PTO 1-2 shots, and then, "the barrel is thick, life is short" ...

                if you were careful, but noticed that it wasn’t I who suggested,
                Well, let the sau, once again, the question is emptiness, why do not the existing art systems eliminate you, and the same a19? at the same time, the created, debugged production scheme, and successfully inserted into the sau when it was necessary to bung D-25 again.
                there was nothing right there, no shells, no solved problems, no production, nothing, but it had to be dealt with only because you know about the Tiger, and at the same time you are proposing to use not a separately invented weapon on the sau, but a triple alteration from the PTO.
                do you give a guarantee that something would come out efficient from m75?
                do you, a person living in 42 promise by the summer of 43 a super-gun for a tank, with well-established production, with shells, etc.?

            yeah, the above 107 mm gun didn’t hit the tiger from 7 shots ever. Coverage is equal to ML20, only she will have to shoot on a direct fire, well, this is a trifle, right?
            once again, 7 shots-hits = 0.
            But this does not bother you in any way.
            while the manual clearly writes, shoot, from 107 and 152 only a group of 3-4 guns.
            but mlNXX is not a weapon

              it’s not that exactly the M75 and the point are just NEEDED TO WORK. Moreover, the tendency is towards heavy tanks. Before the war, our military were sure that the Nazis would have it. But they didn’t bring the gun to mind. That the results are not so hot, it is treated by eliminating the shortcomings, and not by stopping the tests. as a result, towards the end of the war, they again began to look at 100mm

      I want to remind you that the equipment is being created in the future, we created a square (name the tank equal to it in 1940), the Germans gave the mission to the tiger ... in 1940 or 1941. used near Kursk. occasional break-ins do not count. so it went fine-tuning. and having received the tiger with a trophy near Mgoy, our people understood that there was NOTHING to beat it with Ml20, but 19- not anti-tank guns. It’s 2-weak. How much time did it take to get acquainted with the tiger until the T34-85 and Is2 appeared? parts? because there was no groundwork and there was nothing to set. near Kursk anti-aircraft guns were used as ptos! and remember, you won’t create a technique without testing.

        True, they tested and understood, in the archive, and intensely engaged in the production of not a wunderwaffle, but a deed,
        for example, the production of cumulative shells, and in the end we achieved that the 45ka showed very good results in both the Tigers and CT.
        it’s not always necessary to go with a blunt increase in the mass of the shell and its caliber.
        I don’t understand, why are you all trying to prove that it was a good thing?
        8 tonne, 2 meter crap with a rate of 5 rounds per minute?

        The Germans used anti-aircraft guns to fight HF already in the 41st, although they knew that we had such tanks, is that not a miscalculation? What kind of perspective was this among the Nazis that they did not have effective means of struggle against existing tanks?

            so unpleasant that at least one pair of 88 was introduced into each campho group at the tip of the breakthrough, and the staff etc. introduced 10 cm guns?
            apart from the fact that regular means T34 quite amazed himself.

            near Kursk anti-aircraft guns were used as ptos!

            in Belarus, 41, Under Stalingrad, 85 was used as a tanker! under Tula and near Moscow, so what?

      and think about what to do, how to act, how to spend energy and resources

      So, it was from 1942, from its beginning, ALL test pilots, engineers and designers of defense enterprises responded from the fronts, the USSR ATOMIC project began to gain momentum ... That is, the country began to work for the future, no matter what ... , here it is ...

    In 1941, no one in the world had tanks that even came close to the T-34-76 and KV-1. Let's say they would have adopted the M75. To hit the T-3 and T-4, the 76mm caliber anti-aircraft missile was enough. That's when the Germans appeared tigers and panthers. Here then the country made the corresponding conclusions in this direction. I don’t think that Voronov was so stupid that Stalin assigned him the rank of Marshal of artillery. And we don’t need to discuss marshals and their decisions.

    so, to summarize and sleep)
    So, we mean the project of a powerful cannon, made in six months and tested
    what is-

    - as the PTX M75 was completely nonexistent, heavy, high, slow, with 6 speeds / min, but 163 mm per 1 km (which is not a fact, usually in the series the copies were worse than the experienced ones, and the penetration in the series fell, wartime all the same)
    - from a technological point of view, a crude, unfinished product with a bunch of jambs, such as the survivability of the M-75 barrel, which turned out to be extremely low due to the strong height of the barrel channel (hi armor penetration).
    - from a production point of view - a complete zero, in the spring of 42 it was necessary not only to put on production a new type of gun, fix its jambs, but also to restart the interrupted production of 107 shells (as already noted above are already correctly noted), especially since there weren’t even the necessary gunpowder and phlegmatizers have been created.
    and all this is not only not in the easiest period for the country, when the tiger has not yet arrived at the neutral, and the Germans had no burdens,

    and Voronov sayswhy goat slaughter to the archive,
    How wrong you were, Comrade Future Marshal .... as they say here.

    it would seem yes, of course, people were excited about 163 mm at 1km, the end to ferdinand, but ...
    I think in the 43 year you understood this, remembered, and ....

    According to the documents, the M-75 was pulled out of the naphthalene again in September 1943. The reason is simple - something was needed to fight “Ferdinand”. True, they quickly removed it there, this time forever.
    "4. In view of the fact that the 107 mm M-75 cannon with an initial speed of 1020 m / s is completely unfinished, and there is no production of ammunition for it, it is more profitable to work on a more powerful 122-mm gun with an initial speed
    spine of 1000 m / sec. "

    point

    but time itself confirmed that Voronov was right; they didn’t even get this system anymore.
    Well, what about Has come back with many hundreds of lives. it is not known how jumping from one artillery system to another, fine-tuning the supergun, setting up production "for the future", at a time when the country needs now, today needs what it needs, not crude projects and unclear prospects.
    I note, until the end of the war, more developed weapons systems did not go into the series, if at least they broke or reduced production.

    Thank you all, the report is finished))

    Not only is the projectile discontinued, it is also SEPARATE loading, which is unacceptable for a PT gun. In addition, with a mass of 7500 kg, penetration of 160 mm. Compare with the BS-3 penetration the same ammunition unitar weighing 3650 kg. Do not forget about the dimensions.
    Imagine, in the 41st they put it on a series, the war began, the question immediately arises, What tanks should I shoot from it? If they were going to shorten the barrel of the ZIS-2 due to the excess power and weight of 1050 kg, then what to do with this monster of 7,5 tons? And instead of 107-mm, you can make 12 (!) 41-mm guns arr. 45, which are more necessary in 37. And it would have turned out like the 44-45-tuev Hans have a lot of guns in development, and, apart from 88, there are no other AT guns, and the designers are busy, "working for the future, creating masterpieces." Let's start production in 45 or 46, and Russian tanks are already washing tracks in the Oder.

      ... and SEPARATE guidance by two gunners belay
      It is a pity that neither the article nor the discussion mentioned the place of this system in the troops. Here the fun begins smile

    The devil knows ... On the one hand, they could have received a cannon back in 1941, which for another 30 years could easily herach all tanks in the world. On the other hand - 7,5 tons for 107 mm - an overkill ...
