The development and design of Lin Han's Zoo tank must be forward-looking. The development cycle of a tank is very long, and the development progress of the opponent's tanks must be taken into consideration before designing. Rather than just treating a headache and treating a sore foot, the biggest advantage for time travelers is that they can know the progress of their opponents' technological development in advance and formulate their own corresponding development standards. For World War II, the development speed of tanks and the improvement of aircraft performance were very similar, both were the same every year. The classic two years ago became obsolete two years later after various countries caught up with each other. The situation was most prominent among the Soviet Union and Germany. In this historical dimension shattered by Lin Han, although Lin Han and Hannah formulated a strategic policy to unite the Soviet Union and reden Europe, they could not predict how long the fragile "peace" between the Soviet Union and Germany would last, so in When formulating a tank upgrade plan, everything is based on worst-case scenarios. On the opposite side of the Soviet Union, out of fear of "travelers" and "prophet", Stalin also used a whip to force Soviet designers to continuously develop and upgrade new tanks so that they could gain more "security". Therefore, although the two countries have always been at peace , but the replacement speed of armored troops is extremely fast. For the German armored forces, their biggest problem is that due to the restrictions of the Treaty of Versailles, the development of the entire country's military industry has been suppressed for a long time and has been unable to develop normally, and it has been forced to "herd sheep" for more than ten years. The development and design of tanks must also be carried out step by step and accumulate technology bit by bit. When the German tanks were being developed, Hanna didn't want to go straight to the top and develop a thirty-ton tank, but this was simply impossible. The most important thing in the development of technology is accumulation. If you ignore the reality and directly add tanks of thirty, forty or even fifty tons, you will be in trouble. (P.S., I saw a bunch of novels about World War II. Some ignorant authors gave Germany tigers and leopards weighing 40 to 50 tons in 1939, not to mention whether Germany in this era had this technology. Just It is also unfeasible in terms of tactics. The poor road passability of the Tiger and Leopard is also a disaster on the Western Front. ) The Lin Han family knew this very well, so from the beginning, they developed the technology of "running fast in small steps". development plan. In the process of technological development. The biggest difficulty is that it is difficult to determine the direction of "research and development". When an emerging technology develops to a certain level, it enters a fork. Faced with multiple branches that suddenly appear in front of them, each of which seems to lead to the end, scientists are often at a loss when they reach the intersection. The last thing you can do. Either choose a path like a gamble, or rely on your wealth and not be afraid of burning money, try every path, and use practice as the absolutely correct "means" to test the truth, and "burn" a path by burning money. Way to go. But for Germany, which was still in the abyss of economic crisis in 1932, it was impossible for them to burn their way out like the wealthy Americans. And Germany in the original historical plane was just because it didn¡¯t know the direction and wanted to try everything. It cost countless funds and wasted a lot of time, causing the tank development progress to fall seriously behind. In the end, it directly distorted the technology tree and chose the worst path: the most wrong direction of overlapping road wheels. However, in this dimension of Germany, thanks to the help of time travellers, Lin Han and Hannah from the rear style are very clear about the development direction of tanks in the next ten or even fifty years. From the very beginning, the development of German tanks. The three major development directions were decided: larger diameter road wheels, inclined armor, and torsion bar spring suspension. The long-term plan for tank development is to take a thirty-ton tank, an 88 mm ~ 105 mm tank gun, a diesel engine, and a universal chassis as the ultimate goal. History of the development of the Panzer No. 1 tank As early as 1932, before Hitler was elected German Chancellor half a year earlier than history, the German Army Ordnance Bureau secretly ordered the development of a low-cost transitional tank that could be produced immediately in 1931. Several companies openly bid for the design. The results are very similar. The military finally selected the lka1 chassis designed by Krupp. To keep it confidential, it called it an agricultural tractor. If the original history continues like this, it will take Krupp about a year and a half, that is, until April 1934, to officially finalize this model of tank. That is, the famous 5.5-ton No. I tank in later generations. The Panzer 1 tank developed and designed by Krupp is an out-and-out training tank with a two-person crew. The weapon can only be equipped with two 792mm machine guns. The armor is thin and often has many openings, cracks and welds. The strength of the vehicle body Worse, even if it is an anti-tank gun, even a machine gun or anti-tank gun with a steel core armor-piercing warhead can easily destroy it. ¡°However, after Hitler came to power half a year ahead of schedule in 1932, under the intervention of time travellers, the rudimentary lka1 chassis of Krupp Company that had been developed was directly thrown aside. Know that you are racing against timeHitler had no time to wait for Krupp to perfect his design. He directly asked Krupp to copy the famous British Vickers light tank design and set a hard target: before August 1933. More than five hundred tanks must be produced and delivered to the Army's tank instructors. Prior to this, Germany had secretly obtained a Vicker tank through the Soviet Union, and the Soviet side resold the drawings of this type of tank. (Note: The purpose of the Soviet Union's initial purchase of Vickers MKE was to evaluate this tank. The test results found that MKE was even better than the tanks they developed themselves, so they purchased the production license from Vickers and mass-produced it in the Soviet Union. , the Soviet-made MKE is the T-26 light tank. At first, the T-26 produced by the Soviet Union was in the A configuration (replaced with a Soviet-made DP machine gun), and then the turret was modified into one turret with a 37mm gun and another turret. The hybrid configuration is still equipped with machine guns. These two configurations are not produced in very large quantities. The real mass-produced version is the B configuration modification, which is equipped with a 45mm tank gun and 2 machine guns. The final production T-26. In addition to switching to the welding method, it also adopted a cast turret with a bullet-proof configuration.) Krupp Company directly began to produce the German version of the Vicker Tank based on the Vicker Tank drawings provided by the Soviets. Germany. The Army named it Panzer 1. During this period, Germany also obtained a Soviet improved version of the Vicker tank - the famous T26 light tank. (Note: Historically, during the Soviet-German honeymoon period, military exchanges between the Soviet Union and Germany were very extensive. The early Type 3 tank was even tested in the Soviet Union.) After absorbing the characteristics of the two tank designs, Krupp tank designer, made the following improvements to the Vicker tank at Hanna's request. 1. Strengthen the strength design of load-bearing suspension components and make improvements similar to t25. So that it can meet the design standards of the ten-ton tank proposed by Hannah. 2. Refer to the layout structure of T26 and change the two-person crew to a three-person crew. 3. Expand the turret seat ring and redesign the turret based on the sketch provided by Hannah. Increase the clearance of the rear seat so that a 40 mm/60 caliber anti-tank gun can be installed. Although the impatient Hitler set a hard target of delivery by August 1933, Krupp, which was actually completely unprepared, delayed the start of mass production of tanks until November of that year. Only the production plan of 300 Type I A tanks was completed. The remaining 240 Type A tanks were ordered by Mercedes-Benz and Iristifa during this period. The main reason is still the restrictions of the Treaty of Versailles and Germany¡¯s poor military production system. After knowing that the production of the German industrial system was so delayed, Hitler had to make strategic adjustments to the German domestic military industrial system from the beginning of coming to power, which also affected the production of this type of tank. However, the Type 1A at this time can only be said to be a semi-finished product - the 40/60 caliber anti-tank gun that it supports does not even have a shadow at this time. The 540 Type A tanks received by Guderian's three tank instructors could only be temporarily equipped with a 792 mm machine gun to make up for it. Not only that, in order to speed up production and save costs. Although this batch of No. 1 tanks can fully withstand a weight of ten tons, the Type A armor has been thinned to 8~12 mm. It can only withstand rifle and ordinary machine gun bullets. It can be easily penetrated by a professional anti-tank gun. Frontal armor. Among this batch of No. 1 tanks, only twenty of the ten-ton Type B were built for chassis testing to provide experience for future improvements. Although this type of tank is extremely poor in terms of combat performance, it also has an advanced shining point. Compared with its prototype Vicker tank, the front of the vehicle body is flattened into a complete armor plate tilted at 60 degrees. The model is very similar to the future 1936 model Vicker Tank. It's just that the turret was replaced with a larger turret to facilitate the installation of larger-caliber artillery in the future. In addition, another advanced aspect is that in order to facilitate production, the appearance of the entire tank chassis is designed to be "straight without bending", reducing the folding step structure of corners as much as possible, and "using the entire armor plate" as much as possible. Its appearance has a streamlined "smooth beauty" - early tank designs, even before 1942, tank designs from various countries are very strange in appearance, whether it is the Soviet Union's T26, BT5, or BT7 , or the British fleet of cruise tanks or infantry tanks. Or French tanks, as well as the American M2 and M3 series, as well as the German No. 1 to No. 4 tanks and even the Tiger tanks in history. Their body shapes all look like terraces, with uneven heights, right angles and corners. . Not to mention that this design is useless, it not only increases the manufacturing time, but also seriously affects the defense strength. In terms of aesthetics, it can be described as "horrendously ugly". "This kind of bad tank appearance design, historically, it was not until the war progressed to 1941 that all countries gradually realized that the original appearance design was simply stupid. This??Tanks with "streamlined and smooth" appearance have been developed one after another. The Type 1A tank is equipped with the German Army Instructor. Due to its beautiful streamlined appearance, it quickly became popular among tank soldiers and gave it the nickname "Wedding Car" - which means that you can drive this tank. Go and get a wife. In addition, another advanced point is that although this type of tank is used as a training vehicle to equip troops, it is equipped with the most advanced transistor radio and vehicle communication system early, which is of great significance for collaborative operations. However, when this type of tank participated in the Spanish Civil War, Germany deliberately removed the electronic equipment on the tank in order not to expose the importance of the radio too early. After the Panzer 1 tank was equipped with the German Army Armored Instructor, it was on the verge of debuting in official publicity and became a dazzling star in the media for a time. At that time, the British deliberately compared photos of the Panzer 1 tank with photos of the Vickers 6-ton tank. They pointed at its suspension and mocked the Germans for shamelessly copying the Vickers tank's suspension design, and pretended to be disdainful. Authentic: "Don't think that because you have moved your head (referring to the turret) and put on new clothes (referring to the different appearance of the vehicle), we will not recognize that you have copied our design." After the No. 1A type equipment troops. There were many problems. The first was the problem of insufficient engine horsepower. It originally used a 100-horsepower air-cooled gasoline engine. Its use on the weight-reduced version of the seven-ton Type A tank can only be said to be barely adequate. When used in the ten-ton Type B, the power problem is very obvious. Because the engine horsepower was less than three days, problems occurred every three days, and a new engine had to be selected. That is, the later developed Type C and Type C were replaced with a 120 horsepower water-cooled gasoline engine. However, at this time, because the military's production focus had shifted to the No. 2 tank, the Type C tank only received an order for 200 units, all of which were produced by the Iristifa Company in 1934. At this time, although the German side had developed the pak3640mm/45x tank gun. However, both Lin Han and Hannah knew that on the future Western European front, the 40x/45mm tank gun would not be able to defeat the tanks of the British and French coalition forces, so they were not enthusiastic about the production of this tank gun at all. According to Hannah's suggestion, Hitler requested that the barrel length be increased to 60 times the diameter. Because of this length of barrel, its barrel production tasks overlap with those of the Bofors anti-aircraft gun. Coupled with the outbreak of the war in China at that time, the official request was to give priority to the production of 40mm Bofors anti-aircraft guns. The result was a serious shortage of 40mm tank gun production capacity. The 40mm tank guns produced were also snatched away by the more advanced No. 2 tank. So until the C type, the No. 1 tank was always forced to use machine guns as its main weapon. Model No. 1D was developed in June 1934. A 792 machine gun was replaced with a 20mm machine gun, and this tank was finally equipped with an artillery gun. At this time, the focus of German tank production has completely shifted to the Panzer II tank. The production of the specially produced D-type tanks is very small, with a total output of less than 20 units. Most of the D-types equipped in the army are from the existing A~ Upgraded from Type C. The e-type is a version equipped with a 30mm mk108 cannon. It is similar to the d-type. They are both improved from the old model. There is not even one specially set up for production. This type of tank was mainly exported to Spain to participate in the Spanish Civil War, because the Germans deliberately dismantled the radio in the tank when exporting. Coupled with its poor firepower, its performance on the Spanish battlefield was average. However, after the Spanish Republican Army received the No. 1 tank, it usually installed the 45mm tank gun from the damaged and scrapped T26 tank onto the No. 1 tank. Since the turret of the No. 1 tank is designed and prepared for the 40mm/60 tank gun, it is not a problem at all to install the 45mm/46 caliber gun of the T26. It has achieved a lot of results, but the shortcoming of too thin armor has always been a problem for the Spanish. The Type F appeared before the Battle of Poland. At this time, the No. 1 tank finally ended the embarrassment of having only 8 to 12 mm of armor. The armor protection was upgraded according to the needs of the war, and the total weight was increased to ten tons. The G-type appeared after the end of the French War in 1941. Its artillery was installed with a 47mm/35W tank gun disassembled from the captured French B2 tanks and S35 tanks. After the Battle of France. The German Army captured a large number of tank guns of this type from the French and used them to upgrade the firepower of the domestic No. 1 tank for the purpose of recycling waste. However, at this time in Germany, the medium tanks were dominated by the Panzer III tank, and the light tanks were dominated by the Panzer II tank. The Panzer I tank was used as a training vehicle. Although it was equipped with artillery, it could only retreat to the second line and act as a tank. Used for school training, this is also the ultimate improved version of this model of tank. Until the development was finally stopped, this tank did not use the 40mm/60x tank gun he wanted. No. 1 tanks were exported abroad at very low prices as "war surplus" materials after the war. Finland purchased ten of them, and Yugoslavia, Romania, Hungary and other countries purchased dozens of them. In addition, Germany also used "militaryTwenty and ten Type 1 G-type tanks were donated to Norway and Denmark in the form of "aid". These countries purchased the Type 1 tank mainly because of its simple structure, low cost of use and maintenance, and its suitability to serve as a tank training vehicle for armored forces. The country that received the most number of Panzer-I tanks after the war was German Poland. After 1943, Poland was partitioned under the bayonets of the Germans. After a large amount of territory was cut off from the Soviet Union and Germany, it was once again cut off. The country was "restored". Out of political necessity, the Germans "gifted" one hundred early Type 1 tanks as a gift to the "German Republic of Poland" they supported. In order to disgust the Poles, the Germans are still here. On the territory of the former Poland, a land of 20,000 square kilometers was allocated to establish a Gypsy kingdom. Then, in cooperation with the Soviet Union, the two countries collected Gypsies from all over Europe, and then forced them to use trains one by one. They were transported here and helped them establish a Gypsy republic. In old Europe, Gypsies were more disgusting than Jews. Both Stalin and Hannah hated them. They only liked wandering, stealing, and telling fortunes. A hard-working nation that refused to be quiet. This act of forcing the Gypsies to establish a nation by the two countries has been praised by all of Europe, and has helped everyone solve the problem of Gypsy thieves once and for all. After its establishment, the Germans also gave thirty Panzer No. 1 tanks as gifts. In Asia, China and Lanfang received a total of three early Type No. 1 tanks. The two companies requested these two tanks to fill their respective tanks. Museum inventory. There are two Chinese vehicles. One is an early model A and the other is a model G. The one obtained by Lan Fang is displayed in the Military Museum Tank Park in Shanghai. This tank is placed in the museum in New Kunlun, the capital of Lanfang. It is one of the few E-types exported to Spain. Among the German armored forces, the nickname of the No. 1 tank was "Little Mouse". This nickname was given by Lin Han. Out of a bad taste, he and Hannah gave every tank developed by Germany an animal nickname. As a tank, the total number of tanks specially produced by the German Army was less than 800. Artillery tractors and ammunition transport vehicles were modified from its body. More than 300 six-ton ??armored tractors were produced. The No. 1 tank itself basically did not participate in the French campaign on the Western Front. Vehicles and armored tractors appeared in large numbers on the French battlefield. Their main tasks were to fill artillery tractors and ammunition transport vehicles. Unlike in history, the number of tanks in the hands of the German armored forces was very sufficient during the French campaign, so the protection was weak. The No. 1 tank was not sent to the battlefield. Instead, various deformations of this tank were used. The most famous deformation vehicle was a self-propelled rocket launcher equipped with a 2x4 eight-unit rocket launcher. When it was launched on the French battlefield. The screams left a deep impression on the British and French forces, and they were nicknamed Hitler's Accordion. History of the Development of the Panzer II Tank The Panzer II tank was mass-produced in the second half of 1935 and was produced in total until the production line was completely closed in 1941. With a total of 1,600 vehicles, it was an important main force of the German armored forces in the One Year War. It was one of Hitler¡¯s key development projects after coming to power half a year ahead of schedule in 1932. First of all, people from the German Machinery Institute, based on the three major indicators proposed by Hannah, changed the German tank development plan as the first priority development project. For this reason, they even stopped the development of the original No. 1 tank and directly copied Vickstein. Gram, and focus all manpower on this 13-ton tank development project. The No. 2 tank was established as a light tank project with a four-man crew and a 40 mm/60 caliber tank gun. The design weight is 13 tons, and the improved version with enhanced protection increases to 15 tons. In the German army, it is called the Wildcat tank. Except for the temporary use of a 13mm range-finding machine gun instead of the artillery for tank crew training due to insufficient artillery production in the early days, this tank has always used the 40/60 caliber tank gun. This pak3640/60 tank gun uses the same barrel as the famous Bofors anti-aircraft gun. In the early days, due to insufficient barrel production capacity, production was once limited due to the priority given to the Bofors anti-aircraft gun in the armament plan. They had to spend foreign exchange to import 400 gun barrels of the same type from Sweden to supplement them. The first prototype car was built in April 1934. There were five cars in total, and rigorous and repeated testing was carried out. The production drawings were finalized in May of the next year, the production line was ready to begin mass production in September, and the first batch of 54 No. 2 tanks rolled off the production line in October. Because some time travelers determined the "correct" development direction from the beginning, from Type A to Type D, in addition to the gradual thickening of the armor, minor adjustments to the mechanical structure design, and the addition of anti-aircraft machine guns, this type of tank Basically no big improvements. The e-type is an experimental model, with only three units produced. The weight is increased to between 20 tons and 25 tons. The main purpose is to test a larger weight.??Extent of damage to the suspension system. In order to provide experience for the development of the next generation of Panzer III tanks. As expected, the internal structures of these three tanks were seriously damaged after the overload test and had to be scrapped. However, all three prototypes were sealed and retained after the incident, and many years later they were sent to the German Tank Museum. The F-type was developed after the One Year War. Different from many previous models, this model has a heavy-duty design of the suspension system and a more powerful engine. It is nominally called Type F. In fact, except for the body, it still uses the body of the No. 2 tank. The internal structure of the car is very different from other types of Panzer II tanks. This type of tank was named Lynx. According to the original development idea, this tank is positioned as a reconnaissance tank. However, the F-type production was very small, and it was stopped after only twenty-five units were produced. The main reason is that at this time, Germany had begun a new universal chassis plan for e-tank vehicles, and at the same time, there were changes in the use of tanks. The mission of reconnaissance tanks was replaced by the planned infantry fighting vehicles. Although the F-type production was small, it was fortunate enough to participate in the war - Israel is the only overseas user of the F-type. When Israel was founded, Germany "generously" assisted them with a batch of "surplus" equipment. Twenty No. 2 F Lynx tanks were sent to Israel and participated in the First Middle East War and the Second Middle East War. On the No. 2 tank, we can see the prototype of the German "universal chassis" idea. At the beginning of the design and production of this type of tank, the development of many deformed vehicles was taken into consideration. In the combat thinking of the German armored forces, the Panzer II tank is used as an auxiliary supplement to the Panzer III tank, and its relatively low-cost chassis is widely used to install various types of artillery. There are many types of deformed vehicles. For example, the No. 2 assault gun is equipped with a 75mm/24x howitzer, the Cricket self-propelled howitzer is installed with a 105mm howitzer, the Moxa self-propelled anti-aircraft gun is installed with a 40 Beaufort anti-aircraft gun, and the turret is removed and a flamethrower is installed. fire-breathing tank. In the One Year War. About 1,300 No. 2 chassis tanks participated in the war on the Western Front, of which more than 400 were his various transformations. On the battlefield in Western Europe, the Panzer II tank and its deformed vehicles served as the assistants of the Panzer III tank. After the founding of New China in 1937. The first tank production line introduced from Germany was the No. 2 tank. However, although China began to try to learn to produce the No. 2 tank very early, due to a shortage of skilled workers, insufficient armor steel production capacity, and self-production of engines, the early output was very low. By the end of the war in 1940. Only more than 200 vehicles were produced. After the war, China obtained the production drawings of the more advanced Panzer III and Panzer IV tanks provided by Germany, and the production plan of the Panzer II tank was stopped. In addition, it was already a peaceful era, and the development of Northeast China urgently needed a large number of tractors. Dongfanghong Tank Factory, which introduced the No. 2 tank production line, switched part of its production capacity to tractors, while its main technical strength was transferred to conquering the No. 4 tank and its improved E36. Due to production difficulties, the production of the No. 2 tank ended in China. Although its output in China is not high, its production process has helped New China cultivate a large number of industrial workers. The most successful variant of the Panzer II tank was the 16-ton light tank destroyer developed and improved based on the F-type body in 1941. The shape of this vehicle is similar to that of the famous Stalker tank destroyer in history. The vehicle is very similar, equipped with a 75/42x tank gun that was replaced and eliminated from the Panzer III tank. The design idea of ??this type of tank destroyer is to deal with the "T34" sea that may appear in the future. However, there has always been a state of peace between the Soviet Union and Germany. The German Army had little demand for its equipment. It only produced 20 vehicles for testing and then stopped the order. It was then sealed as a technical reserve. Although no further equipment was obtained, the research department continued to receive development funds to continuously improve it. Its ultimate improved version was the e10 Stalker II tank destroyer. This situation lasted until after 1948. It was not until the development of a light tank destroyer with stronger anti-tank capabilities and a "swinging" turret that the military ordered to stop tapping the potential of this series. Although this type of tank destroyer is not officially equipped in Germany, it has achieved unexpectedly good results in overseas sales. Finland and Sweden in Northern Europe, Switzerland in Central Europe, Hungary in Southern Europe, Yugoslavia and Greece in the Balkan Peninsula, as well as Slovakia and Poland, which were later "unlocked" by Germany, all like this light destroyer with a simple structure and easy maintenance. . And in South America. The Argentines were also users of this lightweight tank destroyer, the Stalker, and its improved and upgraded e10 tank destroyer. Due to continuous overseas production orders, its production line was maintained until 1952 before it was finally closed. Its production life is even longer than that of the No. 4 tank. And located in the Czech Republic's Skoda Arsenal. We have also obtained the production license authorized by Germany.After Germany closed the production line of the E10 tank destroyer, they continued to produce nearly 300 E10s for their own country and foreign countries before discontinuing production. The users of Stalker in Asia are Malaysians who were dismembered by Lin Han. Only a hundred days after the founding of the People's Republic of China, Malaysia was forcibly dismembered by the "Three Kingdoms" between Japan, Lanfang and Thailand. After the war, they tried their best to improve their domestic armed forces by selling everything they could. They were cash-strapped and couldn't afford expensive tanks. They took a fancy to the Stalkers because they were cheap, and placed an order for up to 150 tanks. Because of its simple structure and ease of mass production, its production technology was exported to "allied countries" in large quantities with the intention of Germany. After the car completed all overseas orders and ceased production in 1946, Italy bought a complete production line for its own production. In addition to Italy, Northern France also obtained a production license for this type of tank destroyer. Panzer III (Little Leopard) Panzer III came from the twenty-ton tank development plan. Initially, Guderian proposed that its upper limit should not exceed twenty-five tons to adapt to European bridges. But one request was later rejected by Hannah. Hanna raised the upper limit to 27 tons and directly pointed out to the tank designer that the tank would definitely have thickened armor and strengthened artillery in the future to increase its weight to 27 tons, so sufficient redundancy must be left during the design. From the very beginning, Panzer III was expected to be the main force of Hanna¡¯s planned future French campaign on the Western Front. (Note: Historically, Germany developed the 15-ton Panzer III tank and the 20-ton Panzer IV tank at almost the same time, but here Hanna canceled the development plan for the 15-ton tank, so the number of the 20-ton tank was moved forward. One, becomes No. 3) According to Hannah's "perfect plan": this type of tank is planned to be equipped with a 75mm/55-caliber main gun, five pairs of large-diameter road wheels, and 60-degree frontal slope armor. Five-person crew. But the plan is beautiful, but the reality is cruel. Germany¡¯s poor and chaotic production and organization capabilities are the biggest enemy of the improvement of military industry. In fact, people from the armaments and equipment department clearly told Hannah: because the structure is complicated. The production man-hours were high, and it was impossible for the military factory to provide enough 75mm/55x tank guns before 1940. So in the end I had to settle for the next best thing and install a 75 mm/42 caliber tank gun instead. Although it is called the Twenty-Ton Project, in fact, during development, Hannah required that it must leave more than 30% of the upper limit of load-bearing excess. This type of tank is planned to be equipped with a 75mm/42-caliber main gun, 60-degree frontal slope armor, and a five-man crew. Taking into account the swampy environment of the battlefield in Western Europe. This type of tank uses 40 mm wide tracks. According to Hanna's plan, after the future French campaign, the production progress of the Panzer III tank will gradually stop, and Germany will switch to the production of 30-ton tanks. In order to speed up the development progress of the No. 3 tank, its design and development is completely based on the enlarged improvement of the No. 2 tank, so the appearance of the two tanks is very similar. Panzer III tanks, from type A to type C, were all experimental types, with low production, only 300 units in total. In May 1938, the final version of type D began to be produced. By this time, the total combat weight had risen to 20 Five tons. At this time, after many years of adjustments in the early stage, the German industry has finally completed integration, ending the chaotic and inefficient production situation. The No. 3D model, which started mass production in March, had only twenty units in the first month, and increased to ninety units in the second month. In September, with the start of construction of the new Nibelungen tank factory in the Ruhr area, Production suddenly expanded to 200 vehicles, and by October 1939, the Soviet Union and Germany jointly declared war on Poland. When Poland was divided, the German armored forces had received nearly 2,000 Panzer III tanks. After the Battle of Poland, during the long winter break, most of the Panzer IV tanks were equipped with newly designed 13mm anti-aircraft machine guns. At the same time, many Panzer III tanks were improved according to the French combat environment, and the side armor was thickened to 30 mm, the total weight increased from 25 tons to 26 tons, and this model was upgraded to type e. There is also an improved version of this tank called the D3, which is a fire-breathing tank that replaces a body machine gun with a flamethrower. This type of tank was customized as a rear tank before the start of the French campaign. A total of ninety tanks of this type were sent to the front line. In addition, the tank repair shop also modified a batch of them themselves. The exact total number is unknown. This type of tank took part in the battle to cross the Maas River and attack the Sedan Fortress. In May 1940, when the Battle of France broke out, more than 1,800 Panzer III tanks raged across Western Europe, causing the famous Panzer III Panzer Crisis. Although the Panzer III tank is due to production capacity. It cannot be equipped with a more powerful 75mm/55x tank gun, and can only be replaced by a reduced version of the 42x caliber tank gun with a relatively simple structure. However, the firepower of British and French tanks at that time was very weak. Even the reduced version of the 42 times 75 gun was frightening to them. This type of tank was an important contributor to Germany's victory in the Western Front. Because of the time traveler¡¯s cheating, Germany¡¯s military industryIts capabilities were almost doubled compared to the same period in history. However, due to the need to guard against the Soviet Union's "joking" on Germany on the Eastern Front, nearly a thousand Panzer III tanks were still placed on the Eastern Front during the Battle of France as a precaution. During this period, Germany's biggest problem on the Western Front was not the lack of tanks. But the attack speed is too fast, and the logistics supplies often cannot keep up. The frontline troops clamoring backwards are always due to insufficient supplies, not insufficient numbers of tanks, so it is of little significance to concentrate too many tanks. After the Battle of France, the "idle" Germans finally had the energy to "slowly" upgrade the tank gun to the scheduled 55 times the caliber. This is the final version of the Type F. But at this time, Hannah's eyes had been fixed on the Panzer IV tank with an 88mm tank gun, and Britain soon succumbed to the attack of the Three Kingdoms Alliance of China, the Soviet Union and Germany. With the end of the war, the production of Panzer III tanks for the Army ceased in 1941. The main task of the idle tank factory is to convert the old model Panzer III tanks. Improved according to F-type standards. After the one-year war, the Panzer III tanks were exported to the Middle East in large quantities. The main user was Israel, which participated in all the Middle East wars and competed with T34 tanks and KV tanks there. Even the T44 tank (later T54/55) fought against it and achieved good results. Although the Panzer III tank even beat the T44 on the battlefield, it is not the reason why it is more advanced than the T44. It's the Arabs' way of using tanks and poor armor technology. If any tank falls into their hands, they will only make a fool of themselves. In addition to the Middle East, the Republic of Orissa was established on the Indian peninsula in 1952. It is also an overseas customer of the Panzer III tank. The Republic of Orissa was established in 1952 after peace talks between the famous Ratani guerrillas and the United Kingdom. It's just that this red game under the banner of socialism, after ten years of performing a double act in India to do dirty work for the British, both the socialist Soviet Union and New China are very suspicious of Ratani's origins. , and the United States promoted that this person was a spy of the British Fifth Branch, so the two families became very cautious about military support to this country. On the surface, the British government has been at war with Latani for so many years, and it is not convenient for them to directly support this newly established country. So this task was handed over to Germany, which was not very involved in Indian affairs. After secretly colluding with Artoria, the Germans sold nearly two hundred F-type Panzer III tanks to the Republic of Orissa in 1955 at a very low price. After receiving this batch of tanks, the Republic of Orissa secretly imported hundreds of diesel engines from the United Kingdom in 1958 to upgrade this batch of Panzer III tanks - this kind of transformation also happened in Israel. Due to the replacement of a more powerful diesel engine, the mobility of this type of tank has been greatly improved. After India became official in 1960, the remaining parts of India were divided by the British into the Republic of South India headed by the Bretons and the Republic of India established by Nehru. The former controls territory in nearly nine states in India. In 1962, the Republic of South India declared war on India and seized two Indian states. During this period, the Republic of Orissa also added insult to injury and seized the entire state of West Bengal. At that time, the Panzer III tank was dispatched on the battlefield and had a fierce battle with the Indian Comet tank. Although the performance of the two tanks is comparable, due to the low quality of the Indian soldiers, the Panzer III tank still has the upper hand on the battlefield. China obtained the complete production line and production drawings of the Panzer III tank transferred from the Germans in 1941, and produced approximately 600 Panzer III tanks before and after. However, the No. 3 tanks produced by China are suitable for the rotten paddy fields in southern China. Most of these tanks are deployed in the newly recovered Annan and Dali provinces. In order to adapt to the poor paddy field terrain in the two places, the crawler track and transmission structure were improved accordingly during mass production, and the crawler track width was increased to 45 mm. In addition to being used as tanks, after the end of the one-year war, the German Army dismantled a large number of early-type Panzer III tank turrets that were damaged in the war and returned to the factory for repair. Use the chassis to install artillery and convert it into a self-propelled howitzer. The dismantled turrets were placed on the ground mud guns of the fortifications used to defend the Soviet armored clusters on the Eastern Front and served as rotating turrets. These ground-rotating turrets had an additional thirty millimeter-thick armor plate on top to protect the turret from falling at a steep angle. Panzer IV Panther Tank A thirty-ton Panzer IV tank. It is a project that Hannah focused on after completing the development of the Type III tank. Its goal is to cope with the future T34 crisis. However, due to the emergence of the e-tank program, the improvement of Germany's surrounding strategic environment, and technological advancements. This tank eventually became a transitional product, but in the history of German tank development, it can be regarded as an important symbol of the past and the future. In January 1941, a prototype of the Panzer IV tank with a truncated barrel, 88mm/52x tank gun and a combat weight of 34 tons began testing at the Bavarian tank proving ground. From the beginning, the design idea of ??this tank was completely copied from the later Soviet T54 tank. It can be regarded as a shrunken version of the T54.? Although the three indicators of mobility, firepower, and defense look very good. Due to serious plagiarism of the Soviet tank design concept, it was criticized a lot by armored soldiers after it was equipped with troops. The main reasons are: First, the body is too short and the ergonomics are poor, which is simply a torture for the tall German tank soldiers. Secondly, there are too few shells, only forty-two rounds, which can only be said to be just enough. (Note: Historically, the Tiger tank had 87 shells, and the Panther also had around 80 shells). The Panzer IV tank began small batch production in the second half of 1942. During this period, it was continuously improved, and the model number changed rapidly. The first three models were only in Improve the tank's mechanical structure and power pack and make minor modifications. After 500 Type C tanks were produced, the Panzer IV was produced. Soon the heavily modified d series appeared. After the D-type, major improvements were made. Compared with the C-type, the D-type no longer compresses the vehicle height excessively, and the vehicle height is increased by ten centimeters. Reaching 253 meters (note that the T54 vehicle height is 24 meters), the interior space layout has been readjusted, the human-machine environment has been improved, a gun height stabilizer has been installed, the turret rotates using an advanced electric rotation/manual hybrid, and the number of ammunition reserves has increased Forty-eight rounds, the length of the main gun barrel has also been increased to 56 times. The load-bearing system was also adjusted to accommodate the increased vehicle weight, which by this time had increased to thirty-eight tons. Its biggest improvement is the change in the number of passengers. During World War II, tanks were generally equipped with five people, namely, commander, driver, correspondent, gunner, and loader. This was also the most efficient configuration in combat. The standard configuration of the first-generation main battle tank after World War II was a commander (part-time correspondent), gunner, driver, loader, and a four-person crew. For example, the first post-war main battle tank, the Type 59 tank and its Soviet prototype T54/55, the American-made M48, and the British Centurion, all have four-man crews. The important reason for this situation is the advancement of vehicle radio technology. In this plane, due to the influence of time travellers, transistor radio stations appeared nearly ten years earlier than in history. Compared with the old-fashioned tube radios, transistor radios are small in size, light in weight, and simple and convenient to operate. They no longer need to be equipped with a special correspondent like the old-fashioned tube radios. The commander of the vehicle can do this task part-time. In addition, another reason is that the newly designed electrically rotating turret increases the turret speed, allowing the artillery coaxial machine gun to replace the role of the body machine gun. After the development of the Type IV tank into the D type, the body machine gun was completely cancelled, with The advantage is that the front armor of the car body avoids openings. The protection is greatly improved - of course, the disadvantage is that there is no place to install the machine gun on the body, and the ability against infantry is reduced. Before 1944, this design seemed a bit too radical. But Hanna considered that war between Sud and Germany was unlikely in the coming years. And now it is technological progress and armored forces (To be continued) (To be continued.)
