- For the Chinese Army, the T-88 has a decisive value. Full text first release
The reason is that the T-88 is regarded by the Chinese Army as the pillar of the ZTE plan, that is, the T-88 is a key symbol of the Army's rejuvenation.
To this end, the Army has put a lot of effort into the T-88.
In the entire T-88 project, the most concerned thing is firepower.
The main thing is that all the tanks developed by the Chinese Army before this have a common problem, that is, their firepower is weaker than the German tanks of the same period. For example, the German army used 100 mm and 105 mm tank guns on its first-generation main battle tanks, while the Chinese Army's first-generation main battle tanks only had a 90-mm tank gun, and the German army's second-generation main battle tanks only had 90-mm tank guns. The tank uses a 115mm smoothbore gun, while the Chinese Army uses a 105mm rifled gun. Although the firepower of the Chinese Army's second-generation main battle tanks has caught up with the Germans by improving ammunition performance and even developing some special ammunition, Chinese tanks still do not have an advantage in terms of artillery caliber. Besides, for a long period of time, the Chinese Army's second-generation main battle tanks have faced the German third-generation main battle tanks, and the 105mm rifled gun cannot improve its performance no matter how it is improved. It surpassed the 125mm smoothbore gun of the same era.
??Obviously, the Chinese Army must change this situation.
The result is that when determining the performance of the third-generation main battle tank, the Chinese Army clearly stated that it must target the German fourth-generation main battle tank.
¡°As a result, it is necessary to use a tank gun with a caliber exceeding 125 mm, and it must be a smoothbore gun.
At that time, the Chinese Army obtained intelligence that the German army was preparing to use a 135mm smoothbore gun on the fourth-generation main battle tank.
This information led the Chinese Army to decide to develop a 140mm tank gun.
?Obviously. This is a huge technical challenge, and this problem almost made it difficult to produce the T-88 main battle tank.
The reason is. Not only has China not developed a tank gun with such a large caliber before, it has not even developed a large-caliber smoothbore gun. \\First release\\
In other words, the technological leap in developing a 140mm smoothbore gun is too great.
In fact, this is why the development work of T-88 lasted for fourteen years, from the project establishment in 1975 to 1988 when it was officially finalized.
What¡¯s even more terrible is that even in 1988, China had not developed a 140mm smoothbore gun.
The result is that when T-88 was put into service. It was equipped with the 105mm rifled gun used on the T-69, rather than the planned 140mm smoothbore gun.
This resulted in an extremely embarrassing situation.
This is, T-88 not only pays attention to firepower. Also pay attention to protection.
On the T-88. The Chinese Army clearly requires the use of composite armor to ensure that its frontal protection reaches the level of 600 mm uniformly rolled armor steel.
To this end, the Chinese Army has spent a lot of money to introduce Chobham composite armor production technology from the United Kingdom.
more importantly. The Chinese Army did not directly adopt Chobham armor, but developed composite armor with better performance based on it.
In the protection test, the protection level of the front armor of the T-88 turret reached 800 mm, and the protection level of the front of the car body was 750 mm.
It can be said that the T-88 was the main battle tank with the best protection performance at the time.
only. While improving the protective performance, it also brings about an inevitable problem. That is the huge vehicle weight.
The combat weight of the basic T-69 model reached 48 tons, which was already a huge monster at the time, nearly ten tons heavier than the German second-generation main battle tank.
However, compared with the T-88, the T-69 can only be regarded as a lightweight player.
The basic combat weight of the T-88 is 61 tons, and the later improved version reached 64 tons. Even at the end of the Cold War, it was one of the heaviest tanks in the world.
To put it bluntly, the huge combat weight is directly related to its protective capabilities.
?Obviously, it is very funny to install a 105mm tank gun on a tank that weighs more than 60 tons. \\First release\\
You should know that the three third-generation main battle tanks of the German army all weigh less than 50 tons, and they are all equipped with 125mm smoothbore guns.
According to this ratio, the T-88 should be equipped with at least a 140mm smoothbore cannon.
The problem is that when the T-88 was finalized, the development of the 140mm smoothbore gun was still in the technical stage, that is, the main technical problems were still being solved.
At that time, no one knew when this tank gun, which the Chinese Army had high hopes for, could be successfully developed.
?Perhaps, there is no way to solve the technical problem at all.
You must know that developing artillery is by no means as simple as increasing the caliber. As the caliber increases, many problems will arise that require new technologies to solve. For example, the chamber pressure of a 140mm smoothbore gun is four times that of a 105mm tank gun, and the maximum temperature in the chamber is 50% higher than that of a 105mm tank gun. This requires the use of strength. Materials with higher corrosion resistance and better corrosion resistance are used to make the artillery barrel to ensure that the artillery reaches its designed service life. In addition, new technologies are needed to solve the accuracy problem of artillery barrels.
In fact, it was not realistic to use a 140mm smoothbore gun at the time.
There is an issue that many people ignore, that is, the weight of the 140mm tank gun shells.
When developing the 125mm tank gun, the German army took into account the problems caused by the weight of the shells and developed an automatic loading machine. Even so, in order to ensure that tank crews can still manually load artillery shells after the automatic loading machine fails, the German 125mm artillery shells adopt a split-loading method, that is, the shell body is separated from the propellant, thereby reducing the load during loading. Labor intensity.
With the physique of Chinese tank soldiers, there are problems in loading 125mm artillery shells.
In other words, if a 140mm tank gun is used, an automatic loading machine must be developed, and separate ammunition must be used.
The problem is that this will definitely reduce the power of artillery shells, especially armor-piercing shells.
At that time, Chinese ammunition engineers had discovered that the power of sub-caliber armor-piercing projectiles was directly related to the length-to-diameter ratio of the bullet core. That is, in order to increase the power of sub-caliber armor-piercing projectiles, it was necessary to ensure that the bullet core had sufficient strength. Increase the length of the bullet core.
?Obviously, this requires the use of integral artillery shells.
It can be seen that when the caliber of tank guns is increased, the weight and power of the shells have become a contradiction.
As the T-88 begins mass production, it is urgent to solve the problem of tank gun power. You know, the Chinese Army will definitely not expect the T-88 equipped with a 105mm tank to fight against the German third-generation main battle tank, and overseas users will not accept such a tank.
At this point, the Chinese Army had to settle for the next best thing, which was to reduce the caliber of the tank gun to 120 mm.
The main thing is that the 120mm integral artillery shell is the limit that the loader can bear.
At that time, the Chinese Army had a ready choice, the 120mm rifled gun developed by the United Kingdom for its third-generation main battle tank.
However, after conducting comparative tests, the Chinese Army gave up this option without hesitation.
The main thing is that at that time, the British had not yet developed fin-stabilized sabot armor-piercing projectiles that could be fired from rifled guns. When ordinary armor-piercing projectiles were used, their power was not even as powerful as the German 115mm smoothbore cannon, let alone the 120mm smoothbore cannon. Compared to the fifteen millimeter smoothbore gun.
As a result, the Chinese Army decided to develop its own 120mm smoothbore gun.
Fortunately, through the acquisition of the German-made 125mm smoothbore cannon, China's arsenal has solved many technical problems in developing smoothbore cannons.
In 1993, the 120mm smoothbore gun made in China was officially launched.
That year, the Chinese Army ordered a batch of T-88s equipped with this smoothbore gun and gave them the official number T-88a.
Strictly speaking, the T-88A is the Chinese Army¡¯s first main battle tank that has reached the third-generation standard.
It is also the T-88A that allows the Chinese Army to have a better main battle tank than the German Army.
In terms of firepower, the T-88A's 120mm tank gun uses integral shells, so its power exceeds the German 125mm tank gun. It is the most powerful tank gun developed during the Cold War. The maximum penetration depth when using tungsten alloy armor-piercing bullets reached 650 mm, and the depleted uranium alloy armor-piercing bullets later developed reached an astonishing 850 mm.
In terms of protection, the T-88a won without any doubt. Even without reactive armor, the T-88A's frontal protection level is 30% higher than the German third-generation main battle tank, and it can cope with early attacks by 125mm armor-piercing projectiles.
In terms of maneuverability, the T-88a does not lag behind due to its larger weight. The main thing is that the Chinese Army has equipped it with a gas turbine with an output of up to 1,500 horsepower, and its unit power is as high as 25 horsepower per ton, while the German third-generation main battle tank only has 22 horsepower per ton.
The real advancement of the T-88a lies in its complete night vision capabilities, that is, it is equipped with infrared imaging equipment.
You should know that the German army¡¯s third-generation main battle tanks still use infrared searchlights, that is, active infrared night vision devices.
?According to tests conducted by the Chinese Army, the T-88aThe effective combat distance during the day is more than three thousand meters, and it can reach two thousand meters at night. However, the German third-generation main battle tank's combat distance will not exceed two thousand meters during the day, and it is only a pitiful eight hundred meters at night. .
If the T-88A has any shortcomings, it is the high fuel consumption of the gas turbine, which makes its combat journey a tragedy.
Even on the highway, the driving distance of the T-88a is less than 400 kilometers, and the cross-country march is even less than 200 kilometers. Because it is not equipped with an auxiliary engine, the T-88a must keep the engine running when performing combat missions, which requires it to refuel almost every day, sometimes twice a day.
Of course, these problems are not serious for the Chinese Army, that is, the Chinese Army has an extremely powerful logistics support system.
Obviously, the T-88A established the Chinese Army¡¯s dominant position in main battle tanks in one fell swoop.
