Although the affairs of Italy are important, China still has a long time to plan. So it's not very urgent. But there is one thing that cannot be delayed, and that is the problem of the new generation of tanks in China. As a traverser from the navy, Xu Jie's understanding of the 2 battle tank is also poor, but no matter how bad it is, he also knows one thing, that is, the design principle of the T34 is still very good, of course, if it is specific to the man-machine efficiency and subsystem, it will be more sad, the problem of man-machine efficiency is that the personnel activity space is too small, especially the loader is particularly tragic, and the subsystem includes the beginning of the V2 engine (V2 was indeed okay at the time, and the potential was good, but the overhaul interval at the beginning was very low. And the lack of radio stations and the shells were too bad.

But in any case, as a layman with historical experience, Xu Jie still put forward some things worth learning from the research and development of tanks, first of all, the first problem is: the weight of the tank must not be too low, and it seems that it is appropriate to be between 30 tons and 34 tons. Like the historical 4 good after changing to the G type, it has no potential, if it were not for a reasonably long 75MM gun, I am afraid that the 4th really has no need to save zài, and the American Sherman and the Russian T34-85, which was popular in the later period, are both 30-ton tanks. As for saying that the tonnage is too high, it is definitely not good, first of all, in terms of the current technical limitations, although this plane has improved a lot compared to the historical technology, it is still far from the kind of technology tree that makes a series of heavy tanks such as the tiger and leopard Pershing. After all, it was a product of the post-40s in history.

And the 30-ton tank is different, the French had almost 2 tons of B1 tanks before the 30th World War. From a technical point of view, if the design is reasonable, then make a 30-ton or so. A more stable tank is still feasible. And from an economic point of view, tanks in their early 30s are also suitable for mass production, and the real mass-produced tank Black Panther in history (Germany is a medium tank, but the Germans call it medium with a weight of more than 40 tons, how can you make IS2 and Pershing embarrassed!) In terms of output, there is also a huge gap with T34 and Sherman, in addition to the national strength, the complexity of its own production is also a very important reason. (Okay.) But even so, the author still thinks that the production of leopards is better than the production of four, well. ）

The second is that the firepower must be enough! After all, the tank is an offensive weapon. If it's defense, leave it to tank destroyers and assault guns. So the firepower must be put in the most important position. HISTORICALLY, TANKS OF THIS TONNAGE HAVE BEEN ABLE TO MOUNT LONG-BARRELED 75MM GUNS OR SHORTER-BARRELED LARGER CALIBER GUNS, SUCH AS THE 75MML60 GUNS MOUNTED ON GERMAN PLANNING TANKS VK3002DB. OR THE 34MM GUNS USED BY THE HISTORICAL T85-85. In terms of armor-piercing ability. Guns with a smaller caliber but a longer barrel have about the same penetration depth as guns with a slightly larger caliber but a shorter barrel. For example, the Leopard's 75MML70 and the Tiger's 88MML56 are basically weapons of the same grade. However, the former is more difficult to manufacture, and the howitzer charge is smaller, and in the face of large inclination armor, artillery with a larger caliber will be more advantageous. THEREFORE, XU JIE WANTED TO EQUIP THIS TANK WITH A SHORTER 88MM CLASS GUN, WHILE LEAVING A LARGER GUN RING TO PREPARE FOR LATER IMPROVEMENTS.

The third is the layout problem, the engine and gearbox are rear-mounted, as is the large-inclination armor. FRONTAL PROTECTION STRIVES TO ACHIEVE A 65MM INCLINATION OF 55 DEGREES IN THE UPPER PART OF THE NOSE AND 80MM INCLINED ARMOR IN THE LOWER PART. The specific degree will be determined at that time. THE STANDARD OF FRONTAL PROTECTION OF THE TURRET IS TEMPORARILY 110MM. If there is any remaining weight, consider installing a gun shield. THE PROTECTION OF THE FRONT IS ALREADY VERY STRONG, AND UNDER THE WEIGHT LIMIT, THE PROTECTION OF THE SIDE CAN BE VERY PROBLEMATIC, UP TO 60MM, BUT IT IS SAID THAT IT SHOULD BE ABLE TO ACHIEVE THE 40MM SIDE BODY PROTECTION LEVEL OF THE PANTHER. However, considering that this tank is not a breakthrough tank, there is no way to reduce the side protection on the premise of ensuring firepower and frontal protection.

The fourth is the power problem, Xu Jie really can't put forward anything to build on the power, after all, he doesn't know anything about tank diesel engines and gasoline engines, considering the current technical level, after researching, the last engine with more than 300 horsepower should not be a big problem. As for the rest of the story, let's take our time.

The fifth is the question of the internal space and number of people in the tank, generally speaking, the tank is 5 people, the driver, gunner, commander, loader and telegraph operator. Would a four-seater car be feasible if the telegraph operator were removed? According to the experience of later generations, it is absolutely possible, but considering the current level of communication equipment, can the crew take care of it? Xu Jie has no idea, this can only be explored by the professionals. Similarly, Xu Jie also has no research on the specific arrangement of the itinerary and ammunition, so he can only let the designers do it themselves.

In addition to tanks, there are various derivatives of the same chassis, such as assault guns, tank destroyers, and self-propelled guns. As the best vehicle for defense, the tank destroyer will definitely have a greater improvement in firepower and protection because of the removal of the turret, which can be seen from the firepower gap between the Cheetah tank destroyer and the Panther tank, 88MML71 and 75MML70 are a grade difference! THEREFORE, ACCORDING TO XU JIE'S ESTIMATE, THE TANK DESTROYER MODIFIED ON THE BASIS OF THIS TANK CAN BE EQUIPPED WITH AT LEAST 88MML55 AND ABOVE ARTILLERY. After all, didn't the Russians install a D30T anti-tank gun on a SU100MML100 tank destroyer weighing more than 100 tons in the later stages of the war. IT IS ESTIMATED THAT THE LEVEL OF PROTECTION CAN ALSO REACH THE STANDARD OF 80MM AND 55 DEGREES OR MORE OF THE FIRST UPPER INCLINATION.

As for self-propelled guns? IN ADDITION TO THE NORMAL SELF-PROPELLED HOWITZER EQUIPPED WITH A 155MM LONG-RANGE GUN ON THIS TANK CHASSIS, XU JIE ALSO WANTS TO MAKE A 240MM HEAVY SELF-PROPELLED MORTAR BASED ON THIS! Because Xu Jie believes that in the future, if the army faces the fortified area, the number of large-caliber heavy artillery (above 8 inches) is too small. And if you rely on the air force, it is difficult to say about the air supremacy on the battlefield, after all, the air force of both the Entente and the Allied countries in this plane is more powerful than in history. Therefore, in order to ensure that the army has sufficient and cheap offensive capabilities, Xu Jie believes that it is necessary to build a heavy mortar to clear all kinds of iron turtles on the way forward for the army.

IF YOU WANT TO TALK ABOUT THE HEAVY MORTAR IN HISTORY, THE MOST FAMOUS IS PROBABLY THE 2S4 TULIP HEAVY MORTAR MADE BY THE FORMER SOVIET UNION, WHICH CAN SHOOT SHELLS WEIGHING UP TO 130KG AND CHARGING UP TO 31KG AT A DISTANCE OF NEARLY 10KM. And because the trajectory is relatively curved, it can attack various surface bunkers with terrain cover, and terrain that can dodge cannons may not be able to block this weapon. And even if it is not attacked, the effect of simply fighting group charges is quite good, and the tracked turf also provides this artillery with a certain degree of mobility, and the survivability will be better.

And if the research and development progress of this tank is relatively smooth, the Huaxia Army is also preparing to develop a heavier heavy tank, this 30-ton tank is just a mass production in the future armored forces of Huaxia, in order to ensure that in the future armored warfare, the Huaxia Army has enough penetration, Huaxia needs a tank that can really be truly finalized. And in this plan, the Chinese Army set the weight of the tank at about 45 tons! "I'm afraid this weight is a nightmare for the current logistics and maintenance department." When he saw the relevant text, Xu Jie said secretly in his heart.

The weight of the Panther tank is this level, but in fact, all kinds of stability problems have not been completely solved from the beginning to the end, at first the engine overheated, and then the engine overheating problem was solved by lowering the engine speed, but then the Germans found that the problem of overheating of the gearbox was not easy to solve. Because this tank was originally added from more than 30 tons all the way to the weight! Many of the subsystems were designed to a standard of more than 30 tons, and in the end, the excessive weight overwhelmed the parts that should not have been in trouble. Therefore, in the end, there are still various problems with the stability of the Panther tank. Relatively speaking, the Tiger is good, the reason is very simple, at the beginning, the Tiger tank was designed according to the standards of the heavy tank, and the test time in the test site was sufficient, even if the problem was modified, so the stability of the Tiger was not bad later.

Although Xu Jie knew that the current heavy tank was limited by technology, Xu Jie still supported the army to conduct some research and technical reserves first, because this kind of tank would be used sooner or later. After all, as a breakthrough weapon, the side protection must also be emphasized, in his plane, many people think that the Tiger tank is more balanced than the Leopard because of its stability and better side protection, compared to the Tiger tank with side armor of 80MM, the Leopard's 45MM side armor is too fragile for the battle defense gun.

The Leopard has such a problem, as a tank whose performance is not as good as the Leopard, the Huaxia 30-ton tank has more problems, the frontal protection is not enough, and the sides are the same slag. If such a tank is used as a spearhead of attack, then the result will naturally not be very good. Therefore, Huaxia needs a heavy tank as the spearhead of the attack, and its requirements are very simple, the frontal protection must be able to withstand the blows of most artillery, and the side protection can resist the blows of ordinary medium-caliber artillery, and at the same time equip a heavy gun that can destroy almost all tanks! ON THE ISSUE OF THE CHOICE OF ARTILLERY, XU JIE PREFERS THE 105MM CANNON, WHICH MAY NOT PENETRATE ENOUGH FOR THE LARGE INCLINATION ANGLE ARMOR IF IT IS TOO SMALL. (For the same level of kinetic energy, at the same technical level of shells, the better the long-range armor of artillery with a larger caliber is on the inclination armor.) And if the caliber is too large, it is necessary to use split ammunition, and the rate of fire of split ammunition will be too low. Of course, this qiē is just a theory, and it will take a long time to realize it.
