A major technician handed Koshkin a form, "General, this is an armor-piercing test we did with the German blunt-nosed armor-piercing bullets that we sent together, and due to the limited ammunition, only 6 rounds were tested at each distance. Pen, fun, pavilion www. biquge。 info”

This is a record of the test of the penetration power of the 88 mm tank gun shell for the armored corps - high-quality homogeneous steel armor, 30 degree angle hit angle: 100 meters from a distance of 120 mm, six rounds penetrate 5 rounds, and the other shot causes a large area of the back of the target plate to collapse; 110 mm at 500 meters, five shots penetrate six, another shot has almost the same effect at a distance of 100 meters, 100 mm at 1000 meters, four shots penetrate six, 90 mm target at 1500 meters, five through six, 80 mm target at 2000 meters, all penetrate!

Compared to the thickness of the armor of the T34-85 tank, the thickness of the homogeneous steel armor in the upper front part of the hull is 45 mm/30 degrees, and the thickness of the lower armor is also 45 mm, with a slight change in angle, 45 mm on the sides and 47 mm in the rear. The front of the turret in the armor of the T34-85 is the thickest: 90 mm, but even then it is extremely threatening at a distance of 2000 meters!

The front of the turret of the T34 is still like this, and once the other parts are hit by the blunt-nosed armor-piercing bullets fired by the Tiger at a distance of 2,000 meters, there is only one result - the game is over!

Koshkin knew that the design idea of the blunt-nosed armor-piercing projectile used by Germany was actually the same as that of the blunt-nosed armor-piercing projectile used in the tank gun designed by himself, the blunt head could effectively prevent ricochets, and at the bottom of the armor-piercing projectile there was a bottom fuse, and there was a small chamber containing a small amount of explosives.

Once the armor plate is penetrated, the explosives in the armor-piercing shell will be detonated, which means that once the fighting compartment of the tank is penetrated by the blunt-nosed armor-piercing shell, all the members inside are basically destroyed; If it hits the power compartment, the engine will also be destroyed - its penetration ability is generally not comparable to that of a carbide high-speed armor-piercing projectile, but the after-effect after penetration is much greater than the latter! (Note that the blunt-headed armor-piercing bullets in World War II accounted for a large proportion of the production and use, and the structure is very different from the long-rod tail stabilized deshelling armor-piercing bullets we are familiar with with smoothbore guns, and the structure is similar to the armor-piercing shells used in naval guns, which generally have a chamber, but the charge is much less than that of high-explosive shells, and the fuse is generally a bottom fuse.) ）

"Have you captured the high-velocity armor-piercing shells used by the Germans?"

This table has already worried Koshkin, and it stands to reason that 88-mm tank guns should not only be equipped with blunt-nosed armor-piercing shells, but also high-speed armor-piercing shells.

"Not a single shot, maybe the Germans have not yet produced cemented carbide armor-piercing shells to match this tank gun, or maybe the Germans have a growing problem with the supply of tungsten ore."

Germany itself can be said to have no tungsten ore resources, and the pre-war imports from China were almost a drop in the bucket for the consumption of the war (probably why Germany popularized fluorescent lamps so early and saved tungsten?). - Personal association, hehe. It is not enough to save everywhere, even if you add those from Spain.

"If it has a tungsten core armor-piercing projectile, the penetration thickness will increase by about 40% within 1,500 meters!" Kokin shook his head - that is, at a distance of 1000 meters, he can penetrate about 140 mm/30 degrees of armor, and the power is increased even more at close range!

Compared with the "Stalin-type", the front upper armor plate of the hull is 70 degrees and 120 mm thick, the side armor plate is 90 mm thick, the rear armor is 22-64 mm thick, and the front of the turret is 102 mm.

The "Stalin-type" is currently being used as an invincible and unshakable battering ram, and no German tank can pose a danger to it at normal distances, but it is difficult to say in the future!

"Mikhail Ilyich, look at the accuracy with which our tankmen shoot at targets with German tanks." Kokin jumped out of the hull, and not far away set up a standard target for shelling, a 90-millimeter-thick armor plate.

Koshkin walked in and looked, "So dense!" ”

There are 5 penetrating bullet holes on the top, all of which are almost squeezed together, and two of them are almost the same, and I measured them with my hands: "Forty times fifty centimeters, how much distance?" ”

"1000 meters, five shots in a row."

The accuracy is amazing!

"If our Type 76 T34 encounters it, we can only find a way to use roundabout tactics and get close from the flanks ****! The Type 85 also has to get close to the normal engagement distance as soon as possible to have a chance of winning. ”

"We have sent our preliminary report to the Commission, and within a few days the units will receive a form of tactical advice against it."

Kokin prepared everything he could, and the opinion table not only explained the various characteristics of the Tiger itself and its tank gun, but also attached a drawing, on which was the outline of the Tiger type, drawing the effective killing parts and distances of various anti-tank weapons.

"Hope to give our tank troops some help......"

As Koshkin spoke, an assault gun drove in the distance: from a distance, you could feel that it was solid, well-protected, and powerful!

"This is our latest SU-100 assault gun, the gun uses the Д-34T 100-mm rifled tank gun designed by Comrade Petrov based on the 100-mm B-100 naval gun of the Red Navy, after testing, the armor-piercing projectile can vertically penetrate 125 mm thick high-quality armor at a distance of 2000 meters, and its technical characteristics can ensure that it can penetrate the armor of the German Tiger tank at a distance of 1500 meters, except for the gun shield!"

Kokin is proud of its simplicity and reliability, but there is also the frustration of the designers: the production of the "Stalin" tank was curtailed on a small scale, and the "Stalin" is the proudest product of Kokin's design, and it also represents the future of heavy tank development.

"The front armor is 75 mm thick, 72% of the components are common to the T-34, 4% are taken from the SU-122, 7.5% are common to the SU-85, and only 16.5% are newly designed. At present, BR-412B armor-piercing shells and OF-412 armor-piercing/explosive dual-purpose shells are used, and the standard high-explosive shells of the Red Navy can also be used, but it is estimated that front-line troops will not use them against infantry. ”

"I've got two of them, and I'm going to ask Kharkov to design a medium tank that can use this kind of artillery, and use it as a "high-low match" with your "Stalin-type" in a year or two. However, now the quality of the BR-412B armor-piercing bullet is worrying, and two batches have been sent over before and after, and the quality is much worse! ”

"The committee has instructed the factory to improve the process, otherwise it would have been mass-produced by me." Kokin said, pointing to the assault gun.

The problem with the shells delayed the serial production of the SU-100, otherwise it would have squeezed the SU-85 assault gun out of the production line a few months ago.

Saying that, Koshkin motioned to the technician who accompanied him to bring his bag, and he took out a few fine tank outline drawings from inside: "This year, it will not be able to be mass-produced, just the T34-85 type, the production line cannot be moved." ”

Kokin took a look: an almost half-egg turret, with 30-degree inclination to the front of the hull.

"The sketch of the shape of the drawings was first sent by the deputy commander-in-chief, and the marshal also said that there may be two shortcomings in this design: because of the bulletproof shape, it may cause inconvenience in operation, and the ammunition layout may be poor once the tank is hit, and it is easy to detonate."

Ko said that Kim did not understand why the marshal would say that, according to his own drawings, the current standard tank crew is still feasible to operate, and besides, tanks all over the world store shells like this.

"The advantage is that it will be as cheap and simple as the T34, and it is suitable for large-scale warfare."

After reading the drawings, Kojin said meaningfully: "The talent of the deputy commander is not something we can figure out, think about AK47." Last year, the marshal gave me a design idea for using an ammunition compartment on a tank, which is very different from the way we currently use the ammunition layout, but it says that I want to use it again when I develop the next generation of tanks. ”

"By the way, is there a name for your new design?"

"Like the T34, the deputy commander thought of a model, the T54."

Kokin chuckled in his heart: Koshkin said that he had slipped his mouth, because even the committee had always thought that the naming of T34 was set by the Kharkov side itself.
