In the past, it has been talked about more than once, from the lightest individual shoulder-mounted ultra-light air defense missile, to a variety of regular air-to-air missiles and High-end Hippocampus rockets, and then to the more expensive short- and medium-range ballistic missiles, all the way to the most expensive intercontinental missiles; All of these ** are essentially based on solid-propellant rockets of a certain diameter, plus the corresponding warhead and supporting guidance system. Of course, there are still a small number of heavy missiles in service today with liquid engines, or hybrid models of liquid and solid-state engines; However, it is undeniable that the vast majority of main battle missiles are mainly based on fixed thrust that is easier to store and launch quickly. The thrust index and range of each solid rocket have a direct causal relationship with their relative diameter. Therefore, for the sake of standardization and engineering, the corresponding fixed thrust diameter of various missiles is also roughly determined. For example, the diameter of the fixed thrust of the shoulder-fired missile mentioned above will basically not exceed 100 mm, that is, within 10 cm; 
However, most of the fixed thrust diameters of air-to-air missiles are within 200 mm, and only a few ultra-long-range models have a fixed thrust diameter of 300 to 350 mm. Most mid-to-high-end rockets have a fixed thrust diameter between 200 mm and 500 mm. The fixed thrust diameter of short-range ballistic missiles is mostly between 1000 mm and 1200 mm. The fixed thrust of medium and long-range ballistic missiles is generally 1400 to 1600 mm in diameter; The fixed thrust diameter of the ICBM in service is basically between 1800 mm and 2200 mm, that is, between 1.8 and 2.2 meters. The question is, since the basic diameter of the fixed thrust of different types of missiles has been roughly determined, which missiles are equipped with the higher number of fixed thrust production? Which missiles are equipped with fewer quantities of fixed thrust production? In fact, there are some relatively unchanged "unspoken rules" in this regard: that is, the number of large-diameter fixed thrusts for strategic missiles is certainly relatively smaller than that of small and medium-diameter fixed thrusts for tactical missiles. After all, even in the craziest era of the Cold War strategic nuclear competition
The United States and the Soviet Union have never allowed their respective ICBMs to exceed 2,000 at the same time, including submarine-launched ICBMs launched underwater, so neither of the two superpowers in the Cold War era has produced more than 2,000 large-diameter fixed thrusts of more than 1,800 mm; And to this day, it is still not completely consumed, after all, the Minuteman land-based ICBMs and Trident submarine-launched ICBMs produced during the Cold War era are still in service. After 2000, more than 20,000 rounds of medium-range air-to-air missiles of the AIM120 series alone were produced. In this way, it can be seen that the supporting 200 mm diameter fixed push must have produced more than 20,000 pieces at the same time. It can be seen that the total production scale of this small-diameter fixed push is more than an order of magnitude higher than the total production of large-scale fixed push with a diameter of 1800 to 2200 mm! So will the total production of relatively small-diameter fixed push be larger than that of large-diameter fixed push? Not necessarily! For example, the Pershing-2 missile, a sharp weapon in the Cold War era, was adopted
It is a 2-stage fixed thrust with a diameter of 1 meter, that is, 1000 mm, and the maximum equipment of the Pershing-2 missile has never exceeded 500; That is, a total of no more than 500 pieces of 1000 mm fixed thrust have been produced. After 1988, all Pershing-2 missiles were destroyed. Not only was the finished product itself destroyed, but also the mold used to produce the 1000 mm fixed push was also discarded. This has led to zero 1,000 mm of fixed push products that the superpowers have been able to obtain today; As a result, although the slogan of threatening to restore the intermediate-range missile equipment has been shouted for seven or eight years, the actual progress is also zero! It can be seen that any kind of diameter of fixed push, once the production line is discarded, it is more difficult to recover than to ascend to the sky! It is precisely because of this kind of historical lesson that some major countries have paid more and more attention to the serial production of advanced solid pushing. The so-called serialization means that it is not simply equipped with one type of missile, nor is it simply equipped with a special missile of one service or branch, but pursues the generalization of multiple services and multiple missiles with a certain diameter and fixed thrust. 
For example, in the past, the most produced may be the 300-millimeter-level fixed thrust, and the final product is the shell of a certain type of long-range rocket artillery. However, the 300 mm diameter fixed thrust seems to be naturally insufficient: it can only penetrate 2 meters of concrete by relying on its own kinetic energy; It is also difficult for the warhead charge to exceed 200 kg; The firing range is mostly within 200 km. It seems to be acceptable as a land battle, but it is difficult to use it as a sea-based and air-based, and the penetration is obviously insufficient to deal with reinforced targets with a thickness of more than 5 meters. However, although the use of ground-penetrating ballistic missiles can directly destroy high-intensity targets with fortifications of more than 5 meters, the total amount available is insufficient because they must cooperate with gyroscopes. As the 850 mm shipborne vertical launch becomes the mainstream, the 850 mm fixed thrust will obviously become a new generation of standard fixed thrust common to the three armed forces: it can be used as a group of 4 rounds and a super-large diameter "rocket artillery", and it can also be used as a standard shipborne ASBM, and can even achieve rapid air launch; The warhead charge is also able to choose between 500 kg and 2 tons at will; 
The firing range is flexibly adjusted from 500 km to 2500 km. This diameter ** can destroy more than 9 into 9 land-based fortified bunkers, and it can also kill all hostile ships in one hit! Therefore, the 850 mm new fixed push, with an annual output of tens of thousands, is not too much; After all, the lack of firepower syndrome is completely impossible!
