 Ultimate firepower: Germany shows 130mm tank gun, power increases dramatically


According to the pictures shown in the video, the highly anticipated 130 mm musket of Rhein metal defense company is equipped with the third generation improved MBT of Challenger 2, and the overall performance is good. As the most practical fire system of the fourth generation main battle tank in the world, the new generation 130 mm smooth bore gun of German Rhein metal defense company is of pioneering significance.

Pursuit of ultimate firepower

In the history of tank development in the world, the militarys pursuit of Tank Firepower can be described as extreme challenge, always trying to achieve the ultimate level under the existing technical conditions. Therefore, the pursuit of the ultimate firepower of tank main gun has been one of the important factors to promote the development of tank.

Since the development of the first generation MBT after the war, the caliber of the main gun has been increasing continuously: from the 100 mm bore gun of the Soviet Unions t-54 / 55 MBT to the 115 mm SMW gun of the t-62 MBT, the 105mm rifled gun of the M60 MBT, and then to the 120mm SMW of the leopard 2 MBT and the 125mm SMW of the t-64 MBT. Therefore, at present, the development of the worlds main battle tanks is divided into three generations, basically taking the caliber of artillery as one of the main standards.

Of course, there is also a special case. For example, the main gun of M1 Abrams, the third generation main battle tank of the United States, was initially developed as a 120mm smooth bore gun imported from the German Rhein metal defense company. However, the development progress of the m256 type 44 times caliber 120 mm smooth bore gun, which is localized and improved by US military enterprises, lags behind and cannot be loaded on time. Therefore, when M1 basic MBT was put into production and put into service successively in 1978, it was equipped with m68a1 105mm rifled gun improved from the main gun of M60 MBT. It was not until 1985 when the improved m1a1 main battle tank was put into production that the m256 44 times caliber 120 mm smoothbore gun was installed. The case that the third generation MBT still used the main gun of the second generation MBT also became one of the main lessons learned by other countries in developing new generation tanks.

In fact, in the 1980s, powerful military and industrial powers, such as West Germany and the Soviet Union, were already exploring the firepower system of the future fourth generation main battle tanks, and the result was 140 mm or even 152 mm high-pressure smoothbore guns. Later, France also produced 140 mm muskets to improve the leclerian main battle tank. However, due to various reasons, these super large caliber high-pressure smooth bore guns have not been put into practice and can only be kept in the laboratory as technical reserves. The reason is that the caliber of the main gun can not be enlarged unrestricted due to the overall design of the main battle tank and the consideration of all aspects of performance.

Consideration and compromise in many aspects

We know that the main battle tank is not only to use powerful main gun to eliminate all kinds of targets, including enemy main battle tanks, armored vehicles, fortifications and personnel, but also to move. The armored protection should be able to withstand the attack of enemy anti tank fire, and the heavy body will affect cross-country ability and terrain adaptability. Therefore, it is important to enhance the main gun power of main battle tank, but we should also take into account the combat effectiveness, adaptability, mobility, trafficability and other aspects of performance to achieve the optimization of the overall design.

The 140 mm and 152 mm high-pressure smoothbore guns developed by European countries and the Soviet Union / Russia only consider to achieve the leap forward firepower enhancement, and the goal is to achieve more than twice the power of 120mm and 125mm main guns of the third generation MBT. The test results show that these two kinds of super large caliber high pressure smooth bore guns have achieved the expected goal, or even better. However, the following is the overall design of the main battle tank brought about a variety of adverse effects, such as: the gun barrel is too heavy, will lead to the tank turret front heavy and light. Especially, the barrel length of this kind of super large caliber high pressure smooth bore gun is also too long, which makes the torque effect more obvious. Then, in order to maintain balance, the rear of the tank turret should be added with equipment or counterweight. In this way, the weight of the whole tank turret will be doubled, not only directly pushing up the weight of the tank, but also making the electromechanical hydraulic servo mechanism that drives the turret to rotate bear a great load. Moreover, the modern main battle tank fire control system also has very high requirements for turret rotation speed. In order to meet the requirements, it is necessary to further strengthen the driving power of electro-hydraulic servo mechanism. In the end, like the domino, the whole tank design has to be pushed down once again, until the weight and volume of the tank increase to an uncontrollable level.

Type 2a83 152 mm smoothbore gun developed by Russia

Therefore, through the technical exploration of large caliber high-pressure smooth bore gun, Europe and Russia have realized the balance between the firepower and overall performance of the next generation tank. Russia did not use the powerful and terrifying type 2a83 152 mm smoothbore gun on the t-14 Amata main battle tank, but adopted the improved type 2a82-1m 125 mm smooth bore gun. Because the barrel of the gun is longer, reaching 55 times the caliber, the Russian side claims that its armor piercing power is more than 25% higher than that of the 120 mm smooth bore gun in Europe and the United States. The Russian media has always been exaggerating the hobby of its own weapon performance, so the author thinks that this data may also have some moisture. Moreover, even if the armor piercing power of the model 2a82-1m 125mm smoothbore gun reaches this level, it is not enough to form a generation difference with the firepower of the third generation MBT.

In fact, in terms of power, adaptability and other aspects, the 130 mm musket of German Rhein metal defense company is much better than the 2a83 152 mm smooth bore gun.

The 130 mm smooth bore gun was named ng130 by the German Rhein metal defense company, which means the next generation of 130 mm tank gun

German 130 mm smooth bore gun leading the trend

The 130 mm musket is called ng130 by Rhein metal defense company of Germany, where ng is the abbreviation of next generation. It can also be seen from this name that the German Rhein metal defense company hopes that the 130 mm musket will become the standard main gun of the next generation main battle tank in European and American countries and even other countries and regions, just like the classic 120 mm smooth bore gun.

In order to better complete the research and development of ng130 130 mm smooth bore gun, the German Rhein metal defense company and British BAE Systems Company jointly established a new joint venture company named rheinmetal BAE land system (rbsl), which is specially responsible for this work. From the first appearance of the gun at the European Defense Exhibition 2016 to the completion of ground launch test in 2019. Now, the research and development of ng130 130 mm smooth bore gun has been advanced to the stage of real vehicle test. It is also because the British BAE Systems Company participated in the research and development of this gun that the improved model of Challenger 2 main battle tank can take the lead in equipping this powerful tank gun in the world.

So, what is the performance of ng130 130mm smooth bore gun? We analyze them one by one.

First of all, in terms of power, the German Rhein metal defense company said that the ng130 130 type smooth bore gun was 50% higher than the 120 mm smooth bore gun with 55 times caliber. According to the comparison of the firepower performance between the old and the new generation of main battle tank, this improvement has reached the requirement of generation difference. Moreover, if ng130 130mm smooth bore gun really achieves this goal, it means that when it launches the latest type of fin stabilized shelled penetrator, the maximum penetration depth at 2000 m distance will be more than 1200 mm!

Ng130 130 130 mm smoothbore gun adopts a 15 liter super large chamber, which is half as large as that of the 120 mm smooth bore gun with 55 times caliber

For this reason, ng130 130mm smooth bore gun adopts a 15 liter super large chamber, which is half as large as that of the 120mm smooth bore gun with 55 times caliber, and the designed bore pressure is as high as 880 MPa. In addition, the new 130 mm empennage stabilized shelled penetrator developed for the gun by German Rhein metal defense company is much longer than that of 120 mm smooth bore gun, reaching 1.3 m, while the total length of the latter is only 0.95 M. Therefore, any main battle tank which is ready to install this type of gun must be equipped with a tail cabin type automatic loader. Manual loading of 120 mm tank shells is close to the limit, and it is very difficult to load 130 mm tank shells. Therefore, it is necessary to use automatic loader.

Secondly, in terms of adaptability, the design of ng130 130 mm SMW gun should also take into account the operational requirements of the third generation modified MBT. Therefore, the barrel length of the gun is controlled at 51 times of caliber, only 50 mm longer than that of the 120 mm smooth bore gun with 55 times caliber. Therefore, through the video, we can see that the ng130 130 mm smoothbore gun is installed on the turret of challenger-2 improved MBT, and the matching degree is also very high.

Of course, the caliber of ng130 130mm smooth bore gun has been increased after all, and in order to adapt to high bore pressure, the barrel wall thickness should also be increased. Therefore, the total barrel weight of ng130 130 mm smooth bore gun is 3 tons, while the original 120 mm smooth bore gun with 44 times caliber has only 1.2 tons. In order to maintain balance, the Challenger - 2 modified main battle tanks turret tail cabin is further enlarged, and its interior is just used to accommodate the autoloader and waiting ammunition, which can be described as killing two birds with one stone.

From the perspective of the development of new generation MBT in the world, the technical standards of the fourth generation MBT have begun to take shape, such as the lightweight of Japans type 10 MBT and Chinas type 15 MBT; the unmanned turret, integrated crew cabin and comprehensive active and passive defense system of Russias t-14 Amata MBT; and the high network informatization of the US m1a2c MBT The heavy defense of the German Leopard 2a7 +, the vehicle mounted UAV of the French leclere main battle tank, and the powerful firepower represented by the German ng130 130mm smooth bore gun. If any country can integrate these design features and elements, it is likely that the worlds first real fourth generation MBT will be born.
