Transmigrated as the Crown Prince

"Your Highness, the Soviets are developing an upgraded version of the KV-1 tank, a heavy tank numbered IS-1. Three prototypes rolled off the production line yesterday. Natasha said the design drawings will be delivered in a few days."

"IS-1? So fast?" After hearing Reinhard's report, Yannick couldn't help but raise his eyebrows. Because of his actions, the famous chief designer of the T-34 tank, Mikhail Ilyich Koshkin, died young. Therefore, there was no T-34 tank in this time and space, and the Soviet army naturally had no chance to explode. T-34 tank sea. Unexpectedly, it gave birth to the IS-1 heavy tank. The IS-1 tank in the original time and space only appeared in 43 years, but now it comes out two years ahead of schedule.

Before the implementation of "Operation Barbarossa", German military leaders reduced the number of tanks in existing and new armored divisions to form more armored divisions. For example, the German armored divisions in 1941 had 2-3 armored battalions, and each division had a strength of 150-202 tanks. But in fact, each division only has an average of 125 available tanks, many of which lack firepower and are outdated models.

At that time, most German armored divisions were equipped with light tanks No. 1 and 2, medium tanks No. 3 and No. 4, and command tanks. There were also 38t medium tanks made in the Czech Republic. Many armored divisions used this tank equipped with a 37mm main gun. The tank served as a replacement for the Panzer III tank.

However, the number of light tanks and command tanks accounts for up to one-third of each armored division. These tanks are only equipped with machine guns and 20mm main guns, and their firepower is seriously insufficient. Therefore, they are unable to compete with new tanks such as T-34 and KV. On the other hand, although the reliable second-generation Panzer III and Panzer IV tanks are enough to defeat older Soviet tanks, such as the T-26 light tank, T-8 medium tank and T-35 heavy tank, they are difficult to destroy the opponent's tanks. T-34, KV-1 and KV-2 tanks. In 1941, the Germans were busy replacing all Panzer III tanks with medium-speed 50mm main guns, while the Panzer IV tanks still retained a low-speed 75mm main gun. The muzzle velocity of the main gun was at least as important as the caliber, since effective penetration of armor plating required high-velocity projectiles. What annoyed the Germans was that their tank guns were unable to penetrate the frontal armor of the T-34 medium tanks and KV-1 heavy tanks that had just left the assembly line.

After suffering a lot of losses, the German army had to step up research and development. Finally, the Tiger tank appeared on Soviet soil at the end of 1942, and the Panther tank appeared in the Battle of Kursk the following year. The emergence of these two tanks broke the advantages of the Soviet T-34 and KV series tanks. The Soviet army also urgently needed a new tank that could compete with German tanks, so the IS-1 heavy tank came into being.

Today's German armored forces are a veritable horde of jackals, and the minimum caliber of a tank gun is 50mm. Faced with an 88mm caliber tank gun, the KV-1 and KV-2 tanks that were rampaging on the battlefield in the original time and space can only behave obediently. After being completely abused, not to mention the other light tanks such as T-26, BT-7, BT-5, etc., they became simply appetizers.

However, Yannick knew that the IS-1 tank was just a transitional model, and its final production was only a hundred or ten vehicles. Although the original intention of the design was to deal with German heavy tanks, after entering manufacturing, it was found that there was still a certain gap between it and the needs of the Soviet army, so only a small number were produced. The IS-2 tank later equipped with a 122mm gun became the most formidable opponent of the German army in World War II.

IS-2 and IS-1 are similar in appearance, but IS-2 is equipped with a D-25T 122mm gun. Although it has a long barrel with a diameter of 5 times, it is actually a howitzer. During the battle, more than half of the IS-2 tank's ammunition was reserved for high-explosive bombs. On the one hand, it was needed as a breakthrough tank to use a large-caliber main gun to attack enemy bunker fortifications. On the other hand, it was also because there were no weapons on the battlefield. There are not so many heavily armored targets that require it to use armor-piercing shells to attack - tanks of the No. 3 and No. 4 levels simply cannot withstand its high-explosive shells. At first, IS-2 only had high-explosive (HE) and armor-piercing high-explosive (APHE) shells available. At the end of the war, the Soviet Union developed a special hollow armor-piercing capped shell (APCBC) for it. . When using a 1kg capped armor-piercing projectile, it can penetrate 160 mm thick uniform steel armor plates at a distance of 1,000 meters, and it can penetrate 120 mm thick uniform steel armor plates at a distance of 2,000 meters.

The most common rumor about the IS-2 in later generations is that the D-25T is a modified howitzer. Its ballistic trajectory is like urine, and its accuracy is even worse. However, it can fire BR471 armor-piercing projectiles at a muzzle velocity of 795 meters per second. Regardless of the weight of the projectile, this level is quite satisfactory for mainstream tank guns at the time, neither good nor bad. The most common 75mm tank gun in Germany at that time had a barrel length of only L46-48 and a muzzle velocity of 800, which was not much better than the D-25T. Even the 88mm KWK36 with a diameter of 56 times, which is famous for its accuracy, had the same ballistic performance. IS-2 is similar but has no advantage.

The main disadvantage of the IS-2 is the tank's own backward sights and tank operators (another one is the rate of fire). During World War II, the Soviet army generally had low cultural and academic qualifications. Tank crews rarely systematically learned to preview moving targets or use axis calibration techniques. The tank's optical sight and gun body were also rarely calibrated, which would greatly reduce the accuracy of the main gun. If it is replaced with a German Zeiss sight and controlled by a German tank driver, the IS-2 will definitely be a terrifying weapon across the battlefield.

If there was only the Soviet Union, Yannick wouldn't care too much, but now that the Soviet Union and the United States have united, the Soviet Union can use the sights provided by the United States. Although the performance is still not as good as the German Zeiss, it is still much higher than the sights produced by the Soviet Union. Combat power will also be doubled.

As far as Yannick knows, in the original time and space, it only took half a year from the prototype of the IS-1 heavy tank to roll off the production line to the IS-2 to enter the battlefield. In other words, in up to half a year, the German tank troops will face IS-2 heavy tanks that are more powerful than in the original time and space.

"After getting the design drawings, send them to Krupp and ask them to build a few. Then take Natasha's intelligence agent to visit and ask him to spread the news back to the country." When Stalin learned about the new tank that he had high hopes for, The performance data is clearly understood by Germany. Will it continue to produce IS series tanks?

During the last Soviet-Finnish war, Yannik sent a counterfeit Lager-3 fighter jet. Stalin was furious and ordered Beria to investigate the matter thoroughly. As a result, all personnel related to the Lavochkin Design Bureau, from senior engineers to ordinary workers, were subject to the most stringent scrutiny without exception. The famous Lavochkin Design Bureau in the original time and space was thus It was paralyzed and has not yet recovered, let alone producing La-5, La-7 and other fighter jets with excellent performance.

I don’t know how many people will be unlucky this time.

But since it can't be used by him, the more deaths, the better.
