After breaking through the sound barrier, rocket artillery can already be used in actual combat, China can not make rocket artillery like the missiles of later generations, with the speed of Mach 3 and Mach 5, rapid breakthrough, that is the speed of high-speed defense-breaking missiles, rocket artillery can only be used as cheap cover firepower at most, from the initial velocity of 50-80 meters per second, rapid increase, under the premise of determining the relative cheapness, the maximum speed will not exceed 650 meters per second, such a speed, is enough amazing.

For the current China, rocket artillery is just starting, the development of experimental rockets is basically completed, this is only the first step of the long march, but such weapons, basically can not be used in the war, laboratory products, mainly for research needs, and highlight the power, cost is the most important problem to consider, but under the premise of really large-scale installation, cost is very important.

China's economic aggregate is extremely huge, even in terms of education and basic support, it consumes too many resources, but the absolute amount that falls on military spending is also quite huge, but China's military establishment is huge, and the army, navy, and air force add up to more than 10 million, and a weapon for large-scale use, if the price is too expensive, is not enough for large-scale procurement.

As far as the current cost of rockets is concerned, China's wealth is abundant, and it hurts to use it, hundreds of times more expensive than artillery shells, this comparison is still artillery shells of the same caliber, not the shells of the highest-end 16-inch guns, even if it is a 16-inch naval gun, it looks huge, it is only four times the price of this rocket artillery, but the power of the 16-inch caliber naval guns is far greater than that of 207 or even 307 rocket artillery.

This kind of disposable thing must be simplified, otherwise, even if it is powerful, there is no need to use it. If you count that, a rocket is more expensive than a large-caliber shell, and he can buy 50 shells of the same caliber, but a rocket launcher cannot complete the work done by 50 shells of the same caliber, and the price is a bit too expensive and too expensive.

To simplify, to reduce costs, first of all, from the material, rocket artillery due to various reasons, the use of aviation aluminum, and added a lot of precious metals as additives, increase ductility and durability, and as a disposable weapon, every experiment, on the real use of one, in order to maximize the access to experimental data, can use the best materials, use the best materials, can use the most accurate processing methods, use the most accurate processing methods, so down, The cost of a single is also large.

This is a common problem of general laboratory products, fortunately, after large-scale stereotyped production, there will be a considerable reduction, China has a complete set of methods in terms of cost, some experimental rifles and artillery, their prices are high, really large-scale production, it will be reduced a lot, basically to the extent that it can be used. For rocket artillery, the same is true, before the sound barrier, resulting in a sharp rise in the cost of the rocket, mainly in terms of aerodynamics, increasing the speed of the rocket, increasing the power, through Yang Yuanzhao's guidance, when the sound barrier is broken, it is not difficult to achieve it, the aerodynamic structure has been made, and then it is modified according to this, many times, it can be achieved without such high-end materials.

In the course of the development of weapons, many encounters, before breaking through a certain boundary, we have to use the most cutting-edge materials to gradually overcome that difficulty, and after really crossing it, we will find that as long as a certain condition is met, it can also produce results without particularly good materials. For example, the MiG-25 is an aircraft that specializes in dealing with high-altitude and high-speed reconnaissance planes of the United States, and when it first appeared, it set many world records, which shocked a large number of military experts, and some people even thought that this was a smokescreen released by Russia.

However, in actual combat, the Americans discovered that the MiG-25 is really so good, he can closely follow the Blackbird high-altitude reconnaissance plane, warn and even shoot down easily, in the high altitude, the maximum speed exceeds Mach 3, such a speed in the vast majority of fighters, there is no way to achieve it. When they didn't figure out the real performance of the MiG-25, the United States and Britain panicked, and they couldn't figure out what it was anyway, so that the MiG-25 had such a powerful speed, the same as the sound barrier, Mach 2.5 would have a thermal barrier, that was a huge obstacle, and even more difficult to break through than the sound barrier, in history, only three aircraft broke through this field, namely the MiG-25, the MiG-31 and the American SR-71 Blackbird.

The price of the Blackbird is expensive, even the United States can't afford it, more than 93% of the whole is made of titanium alloy, and there is no way to even solve the problem of oil leakage, it has been flying, it has been leaking oil, the Americans were very curious at that time, how is this aircraft made to deal with SR-71, is it titanium alloy, why there is no oil leakage problem, SR-71 can only be used for reconnaissance purposes, but the MiG-25 can attack, high-altitude raids, which makes them puzzled.

Sometimes, the secret is broken at one point, is when a MiG-25 defected, the Americans finally figured out that the solution to this problem is so simple, stainless steel can, MiG-25 is a whole made of stainless steel big iron shell, thermal barrier and sound barrier, there is no problem at all, At an altitude of 24,000 meters, it can fly at a speed of Mach 2.8, which is also thanks to this, but in addition to high altitude and high speed, other performance is very poor, and even the radar can not be installed, this defection also quickly unveiled the mystery of the MiG-25, the MiG-25 fighter has its own advantages in many aspects, but in terms of overall performance, it is only equivalent to the American F-4 "Phantom" fighter, and the new F-15 "Hawk" fighter and F-16 "Fighting Falcon" newly developed by the United States at that time The combat apparatus is not much of a threat.

This is the terrible thing to break through a certain boundary, and the same is true for rocket artillery, under the mention of Yang Yuanzhao, after solving the problem of sound barrier with a better aerodynamic structure, the aerodynamic structure of the entire rocket is also determined, and the simplest aerodynamic structure is used to reduce the material of the rocket itself to a minimum, and more cheap and easy-to-forge materials are used, for example, steel with a certain element added, or cast iron, or ordinary aluminum alloy, and less expensive materials, such as, magnesium, lithium, copper and other metals, This will cause the performance to weaken, but under the adjustment of aerodynamic forces, the weakening of performance is directly proportional to the reduction of price, and it can basically be put into actual combat research.

From cheap to high price, the price of this rocket is immediately highlighted, especially the small caliber, in a deduction, even reduced to the price of the same caliber mortar shell 3 times, you know, the weight of the rocket is generally more than 10 times that of the mortar shell, the power of the rocket of the same caliber is much larger than the mortar shell, the gap in the middle is greater, but also the price of the rocket has increased, to a certain extent, the performance of the small-caliber rocket artillery, more than the mortar, will become the object of flexible use of special forces.

Of course, Yang Yuanzhao knows very well that rocket artillery is cheap, but in the field of rocket artillery in the future, the most important thing is missiles, which represents the direction of the future, missiles are never cheap, a real high-performance missile, even higher than the price of ordinary aircraft, this kind of missile is huge, can greatly improve the performance of fighters.

Therefore, with the support of Yang Yuanzhao, after gradually reducing the price of rocket artillery, the rocket is also divided into two different directions, one is of course to reduce the price and make a very cheap weapon, and the other is to pay attention to precision and control performance, and there is no more reliable chip radar for the time being, but the direction is there, using various kinetic energy without change, controlling the trajectory of the rocket, even a little change, will make the final hit point completely different, this is the transformation and controllability of the rocket.

While determining the accuracy of the weakened rocket and reducing the cost of the rocket as much as possible, it also strengthens the research on precision weapons, especially the use of some vectors, such as some control of the rocket, not to be more accurate, but only to change, which is also to prepare for the future of missiles after the emergence of rocket chips.

Two directions, one towards a larger range, more precise control, and even card control progress, Yang Yuanzhao proposed a three-stage rocket, quickly produced, and put into the experiment, the range from 60 kilometers to, 200 kilometers, the progress is very fast, of course, the investment is also high, a launch range in 200 kilometers of rockets, an experiment, is equivalent to about 60 kilometers about 207 mm more than 5 times, with the range increased by 200 kilometers, the price will rise wildly.

The biggest difference between the rocket and other weapons is that the rocket is a one-time consumable, whether the experiment is successful or not, this time the rocket always has to be consumed, with the increase in the range of the rocket, the cost of the rocket has also increased significantly, especially with the use of vector change engines, through certain controls, the operating attitude of the rocket can be fine-tuned to a certain extent, and the increase in cost is even more terrible, 200 km rocket, the price is even more than 5 times that of the previous 60 km rocket, It's almost comparable to a light aircraft, but the role of such a piece of equipment is not great, after all, the range is huge, the longer the range, the greater the proportion of fuel in the rocket, so that there will not be many combat parts, tens of kilograms, compared to the huge range, the power is not great, which is more or less, which makes the researcher a little disappointed.
