In the history of later generations, after the end of World War II, when the Cold War began, there were little changes to the battleship itself, more modern modifications, the emergence of missile-guided weapons, which completely changed the mode of the warship, a fighter with medium-range guided weapons can easily shoot down several ordinary fighters, numerical superiority, can no longer become an air advantage, the backward side, even outside the line of sight, has been shot down, and even the other side can not be seen.

With Yang Yuanzhao's ability, of course, it is impossible to make any artillery sighting radar, precision guidance and the like, this is too far away from this era, and there are too many faults in technology, and the radar project is also underway, but it is the most rudimentary, and in terms of performance, it is quite unstable and is being explored.

In the naval battle of World War I, battleships and other capital ships are still fundamental, Yang Yuanzhao now has a land-based air force, 1.5 tons of bomb carrying capacity, strengthened protection and solidity, can barely develop a dive bomber, can carry about 1 ton of bombs or torpedoes, but these are too sophisticated things, even in China, are prepared to use only horizontal bombing, with a group of aircraft instead of accuracy, let alone in Germany. However, after thinking about it seriously, especially after understanding the command system of artillery, Yang Yuanzhao really used future technology to come up with something that was a little nondescript.

The three most important points of the battleship, speed, protection and firepower, in fact, to put it bluntly, the most important thing is firepower, 15-inch guns, 48 times the caliber, have reached the current extreme, and it may continue, it will be 16 inches. Even the development of 18 inches, there are a series of technical difficulties. Even if the Northwest goes all out to tackle key problems, it will take time. The only thing that can be improved in a short period of time is the hit rate.

From the birth of the battleship, the hit rate is a problem worth exploring, from the initial feeling and experience of dependence, to the salvo of naval guns, the reason why the dreadnought surpassed the former dreadnought, and even made the former dreadnought unable to keep up with the needs of the war, leaving from above the battle line. His main and secondary guns were unevenly distributed, and the number of guns projected in one direction alone was unequal, and when firing a salvo, the splash caused by the secondary guns could even affect the main guns, so that a problem of probability could not be reached.

But the dreadnought is different, the main guns are unified, and the main attack is the joint projection of 8 to 12 main guns, and the guns are uniform. Unified command will make the shooting of the main gun change from a point to an area, so that the firepower projection ability and probability will be greatly improved. This is also the fundamental reason for much more than ordinary pre-dreadnoughts.

But even so, at the same high speed, non-stop operation of the two camps. It's not easy to hit the other side. There are several jù shows that the largest battle of Jutland in World War I was the largest in later generations. In the world's largest battleship duel, some later statistics show that the British fleet fired a total of 4,480 large-caliber shells, of which the first and second battle cruiser detachments fired about 1,469 shells, the third battle cruiser detachment fired about 373 shells, the fifth battleship detachment fired 1,099 shells, and the Grand Fleet fired a total of 1,539 shells.

In comparison, the German fleet fired a total of 3,597 large-caliber shells, of which about 1,670 were fired by the battle patrol detachments, 1,904 by the dreadnoughts of the battleship group, and 23 by the front dreadnoughts.

So many cannons, so many large-caliber guns were fired, but what about the hit rate, the British fleet was hit with a total of 122 large-caliber shells. In total, the German fleet was hit with 123 large-caliber shells. Hit rate: British fleet hit rate = 123/4480 = 2.75%, German fleet hit rate = 122/3597 = 3.39%. With such a low hit rate, the Germans had many hits brushed out by shooting the Black Prince at close range, and if the Black Prince was excluded, then the Germans fired about 3570 large-caliber shells, with a hit rate of 3.08%.

The average hit rate of 100 large-caliber guns is only about 3 rounds, not to mention compared with the guided weapons of later generations, and the hit rate of artillery aiming radar is also greatly inferior.

How to reduce the level of luck, reduce unnecessary and unnecessary mistakes, doesn't it improve the hit rate, according to mathematical theory, the more parameters, the more accurate the parameters, you can increase the probability of some fuzzy numbers jù, in the battleship IQ, that's the case, if you give a mathematician a few days, or give a few mathematicians a few hours, maybe you can make this probability much higher than 3%.

But this is unrealistic, no mathematician is willing to go to the battleship, brave the fire, this kind of calculation, both sides are high-speed warships, often within a few minutes, will issue a series of orders, when for a long time, you calculate the last direction, maybe the battleship has run several nautical miles away, so there is no timeliness at all, it is also a fantasy.

For others, it is a fantasy, but for Yang Yuanzhao, it may not be a fantasy, the advantage of the computer is that a large number of simple, fixed programs of some kind of calculation calculation, during World War II, the most elementary computer developed by the United States, can reach 5000 times per second of computing speed, at that time, the computing speed of the computer, has exceeded the human brain, can be on the password and other more boring and cumbersome calculation problems, calculation and decipherment.

After World War II, there was tremendous development in a series of aspects such as new materials and electronics, and computers, according to Moore's Law, doubled the computing speed every 18 months, and by the time of the 21st century, the floating-point speed of computers had reached a terrible range of 201.4 billion times per second, which was much stronger than the most primitive computers in the United States.

Before, Yang Yuanzhao took out the electronic computer, and let the railway management system in the northwest reach a height that the United States has never reached, it is just an ordinary electronic calculator, his calculation speed is limited, and he can't afford the battleship artillery second system, but what followed Yang Yuanzhao through not only has a calculator, but also a mobile phone, even if it is a copycat mobile phone, it is also a copycat Apple, The main frequency has also reached 1.2G hertz so-so, which is not as good as 201.4 billion times, but it is also better than the primary products of the United States, I don't know how many heels.

It's a pity that such a CPU can't be applied, the computing speed of the computer is just a foundation, in order to complete the actual operation, the system is needed, and when it crosses, it is impossible to foresee the crossing, and get a simulated cannon second software, the advantage of fast calculation speed, but it can't be brought into play.

However, fortunately, the Northwest has made extensive use of computers in railways and various technical fields, and for many scientists, although they do not know what the principle of computers is, they have carried out some control designs through peripherals, used some simple languages and commands, and compiled some applications, which can greatly increase the computing speed in specialized fields, and thus cultivate a group of junior software talents.

Because this is a completely new field, coupled with Yang Yuanzhao's intentional or unintentional promotion, this part of the software personnel, more than 9 into 9, are Chinese and Chinese, which makes this calculation system more secret, after thinking of the cannon second calculation, combined with some professional artillery in Germany, some gunners of the Northwest Army, some mathematicians specializing in mathematics, and probability experts, a research group was formed.

With the help of a special formula, the guns on the battleship are controlled in a unified manner, and a series of calculations are made for the target by means of optical aiming and ranging, and then a method of shooting with the greatest probability is derived, and then the ship's radio and telephone system is used to conduct command operations.

At first, they were in the research institute, and when Yang Yuanzhao left Baotou, they only completed a prototype, but fortunately, all they needed was a computer and some command input machines, moved into the train to continue, and strive to be able to complete the compilation of all calculations and formulas before the battleship was put into use, and then took this rudimentary thing, went up to the battleship, and with the help of the sighting system and command system on the battleship, made a series of adjustments, and strived to achieve a satisfactory process.

At present, the basic interface program has been compiled, and even some parameters and performance of the optical sighting system and ranging system of the new warship as a whole have basically entered this system, with the help of a special input method, you can directly enter the number jù at the lookout point and aiming point, and then transmit the signal to the core computing system, and automatically run the number jù to calculate, if the number jù is complete, the hit probability of a battleship's salvo can even reach about 70%.

Don't overestimate this probability, this is just the hit probability of a battleship, divided by the battleship's 10 naval guns, it only reached about 7%, which seems to be only about double the hit rate of the battleships on the British and German sides during the Battle of Jutland. However, this kind of calculation and number jù reduces a lot of unnecessary mistakes, and reduces factors such as luck to the extreme, this is only a range, if it is with the help of radio, the measurement number jù of 3 or even 5 ships is superimposed together, and if you aim together with this command system, this hit rate will be higher, and the blow to a ship is greater, and the occasional hit, or scrape, and the continuous hit of intensive fire, for the damage of a ship, this is definitely different.

Even in some assumptions, using this system, for some distances beyond the standard range, can also achieve a good hit rate, which has basically achieved Yang Yuanzhao's improvement in firepower, with this, even the future nascent Chinese Navy, in artillery technology, can already catch up with the world's naval powers without gradual exploration.
