Considering that this tank will serve as the pillar of China's armored power before and after the next 2 wars, Xu Jie does not require this tank to be developed at a fast speed, but it must be stable and durable, and has great upgrade potential. It is required to reserve a large enough gun ring when designing to accommodate future 90mml70-level cannons or 105mml52-level cannons. At the same time, it is required to have a certain margin on the load so that additional armor can be added like the Dumbo tanks in history.

However, it is obvious that the performance of such a tank is significantly beyond the current technological level, such as engines, gearboxes and other equipment, need to be redesigned. Considering the experiments and test runs and a large number of equipment, the process will definitely be relatively long. In this case, how to make full use of existing resources to tap potential has become a paper problem for the General Equipment Department of the China Army. As a mass-produced medium tank, the 29 tank is actually very successful. The weight of more than 30 tons is not high or low. If it can be replaced with a new subsystem, the main force of armored warfare will not have any problems in the early stages of the 2nd battle. Therefore, a series of vigorous improvement plans have been opened.

The first improvement is naturally to increase the firepower of the Type 29 tank. A tank with a capacity of more than 30 tons is only a temporary measure. Look at the No. 4 tank of Germany in World War II, which is equipped with a capacity of 75mml48. The Soviet T34 installed the 85mm cannon, and Sherman also had a capacity of 75mml60. So in this firepower upgrade plan, the Type 29 tank will be equipped with a new 75mml60 cannon. Of course, this is just a plan now. This cannon has not been developed yet, and wait until the cannon comes out.

It will take about a year to design the corresponding turret until the final equipment is tested to enter the production stage. In order to balance the weight of the artillery, the rear cabin of the rear of the turret of the 29 tank will be placed in the rear. At the same time, it will also consider replacing a new diesel engine to increase horsepower. As for protection? There is no plan to improve for the time being. After all, with the emergence of the new heavy tank, this tank will be demoted from heavy tanks to medium tanks. There must be some faster tanks in a tank unit. If they are all made into iron turtles, how can they fight in the future?

The second improvement is naturally the various derivative vehicles of the Type 29 tank. Anti-tank destroyers made of the chassis of the Type 29 tank are naturally indispensable. The performance of the chassis that can load more than 30 tons is no longer low. According to historical experience, it doesn’t matter if you are not afraid of tankers protesting. However, considering that the current opponent is not that cruel. At the same time, the 100mm artillery ammunition is too large, and the loading is difficult and the amount of ammunition is relatively small, so Xu Jie believes that it would be better to consider equipping a 75mml70 gun or a 90mml50 gun. In the subsequent bidding, the former was eventually eliminated. 75mmmm

There are several reasons for the defeat of the l70 artillery. First, China has planned to equip the 75mml60 level artillery. Another cannon of the same caliber is not very necessary for logistics supply and military production. The 90mml50 level artillery is a weapon that heavy tanks need to be equipped in the future. So it is also used for tank destroyers, which is easy to save trouble. Another reason is that the grenades of the 90mml60 level artillery are larger and more powerful to deal with bunkers (for example, in history, the grenades of the US m3 type 90mml50 type artillery were 19kg, while the grenades of the m3 type 76mm cannon were only 10kg.)

The artillery problem was solved, and then there was armor. After removing the turret, the weight saved was not only placed with a more powerful cannon, but also strengthening the front armor. After weighing, the thickness of the front armor was increased to 80mm, with an inclination angle of 55 degrees, and the thickness of the lower part was 65mm, with an inclination angle of tilt angle remaining the same as before. In addition to power and weapons, the engine will also be upgraded.

Although the tank destroyer was the earliest type 29 tank derivative vehicle to be launched, it was not the most popular type 29 tank series. It is not that this type of tank has poor performance and is not good on the battlefield. It is because the following tank performs better, has a larger output, and has the widest coverage! According to the response of the grassroots of the troops later, this tank can almost undertake almost all tasks from fighting tanks to anti-infantry and even long-range fire suppression!

This vehicle, which was called the Type 29 assault gun, was equipped with a 122mml35 howitzer. The original intention of its design was to deal with various bunkers and infantry. At that time, when choosing artillery, there were some twists and turns. At the beginning, the 105mm howitzer was the most popular artillery. Especially the 105mm howitzer that used a full-load of ammunition was even more popular. But then a arrogant order from above forced the entire plan to be completely changed! A big man above could not stand a 30-ton chariot that weighed more than 30 tons and was only equipped with a 105mm howitzer! In desperation, the Chinese Army could only study a 122mm cannon. And it was precisely because of this arrogant plan that the 29 assault gun was famous in history.

"The pellets of the 105mm howitzer are too light, only about 10 kilograms. The pellets of the 122mm level are as high as nearly 20kg. The weight of the two sides is twice as different! As a unit supporting infantry, the power of high explosive shells is particularly important. At the same time, it does not require too high firing rate. Therefore, it is not too problematic to use 122mm cannons to load the projectile. Although the 105mm full loading is easy to load, it is difficult to store in a closed combat room because of its large size. Unlike the 122mm cannon shells, the shells can be stored separately from the launching cartridge. Of course, using 122mm cannon shells will eventually lead to a decrease in the amount of ammunition reserves, but overall, this cannon is still better than the 105mm howitzer." Xu Jie explained his decision later.

Therefore, with the powerful grenade, the Type 29 assault gun can deal with almost any non-reinforcement fortifications. The huge artillery can penetrate ordinary medium tanks when equipped with armor-piercing bombs. Later, after the armor-piercing bombs, it will also have a striking effort when encountering heavy tanks. Therefore, it won the title of panacea on the battlefield!
