This cabin embodies the greatest achievements of the Northwest in material science, but this material is more than twice as high as the strongest armor, and wear-resistant, corrosion-resistant, even if it is directly hit by the current largest caliber naval gun, it can also be safe and sound, and the middle filling material is enough to ensure safety under the violent impact.

In fact, these are set up to ensure the safety of the inside, the closed cabin, just like a giant bank safe, the space inside is only less than 10 square meters, can only accommodate one person, and the door can only be opened from the inside, under the cabin, cleverly set up a double door, the outside people through the inside to open the first door, there is a layer of almost half a meter thick alloy door, in the interior of the cabin, set up a special periscope, you can see the outside of the door and the inside of the double door.

The reason why it is so secret, the reason is very simple, the chip of the simple calculator used in the northwest, can not support multi-threaded operations, the function computer after multiple targets, the computing power is significantly reduced, even if there is software to improve, the amount of calculations per second can not go up, since the new generation of aiming devices have been taken out, then the performance must be guaranteed, 28 threads, if you use a calculator to control, Maybe the time of the salvo will be reduced to 1.5 minutes or 2 minutes, which doesn't seem to be much, and the salvo of the battleship is often almost more than a minute, but since the battleships of the Fantasy class and Orion are changed to this level, then the sights are also good.

Yang Yuanzhao is in the performance of the calculator to the extreme, still unable to fully play the role of the sight, so. On the side of the Qingdao shipyard, more advanced computers were used. To put it bluntly, it was once a copycat Apple processor. Although it is not as strong as the genuine Apple, it is still the latest product around 2014, not to mention compared with the calculator, even compared with the computer around 2010, the pure computing power is not much better.

Because of this, he was especially careful not to put such a calculation device until the special cabin was built. Throw on ships other than Chinese ships.

On Cheng Biguang's ship, there is such a huge cabin, only a dozen meters in diameter, but all of them are high-hardness alloys, almost more than 200 tons, which is almost the weight of a battleship's main gun. Installing a 200-ton cabin doesn't matter, but the key is how to convince the other party and get them to agree. On each of their warships, this thing was installed.

The role of a ship is small, only all of them are loaded. The power of 9 battleships will be concentrated together, and it is truly terrifying. Because of Truss's existence. The Northwest's advantage in radio is extremely obvious, and Truss's imagination and the materials of the Northwest are combined into a whole. Let the radio have the style of later generations, not only the performance is quite stable, but the volume has also become very small.

In the special cabin, there are some electrical wiring, which can be combined with the rest of the whole ship, in the special command system in the northwest, 9 battleships are combined together, 82 guns, fired according to the same command, the shells will hit in a rectangular area, in this area, some artillery fire and hits are overlapping, which is even more amazing, although there is a lot of waste, but when at the same point in time, 1 shot and 2, 3 or even 4 or 5 shots, so the result is completely different, under a certain probability, when the 9 is calculated, in the case of a salvo, there is a certain probability that a capital ship will be sent directly to the bottom of the sea.

The most important thing is that the computer's powerful computing power and multi-threading capabilities do not need to be lined up in a neat line, which is a huge advantage, 9 ships together with the help of advanced radio communications, through the powerful role of the computer, do not need to maintain the battle line, can be freely evaded, and even when attacking the fleet, the effect of salvo can be achieved, which is particularly important.

The battle line has appeared since the era of sail battleships, and has gone through ironclad ships, capital ships, all-steel battleships, and dreadnoughts all the way, and the word battleship battleship is derived from the battle line, when a fleet seizes the battle line, it can open the firepower to the maximum, and to this extent, there are extremely strict regulations on the speed, position, and even the number of guns on the ship.

There were submarine experts who even suggested that if there was a super submarine that could catch up with the speed of the capital ship and attack the opponent's capital ship on the battle line, wouldn't the other side be a fish on the chopping block and would not even have the ability to run?

In this way, it is a bit exaggerated, but it represents the old-fashioned and powerful battle line, and now with the combination of the command system and the computer-aided targeting system, a new combat method has been formed, and the combatants are not more rigid than the battle line, and can be free to be anywhere, anyway, when the data of the entire fleet is summarized together, the computer can have leisure to calculate the position of the opponent's ship, and then integrate the artillery of the entire fleet, give a unique launch angle and launch time, and ensure the artillery density per unit area. In some cases, better than the battle line. It can be said unceremoniously that if Scheer knew that it was so powerful, he would definitely change the entire training subject.

Cheng Biguang has the experience of staying abroad, and has also come into contact with some Germans, he knows the old-fashioned style of the Germans very well, fortunately, the navy is an offensive branch, Germany is compared to the United Kingdom, in the navy belongs to the catch-up, Schell is one of the few German navy, a few flexible minds, very strong, want to convince him should not be difficult.

The Wutai Mountain made a turn near Borneo, and without alarming anyone, it entered the exercise area, which concentrated hundreds of warships of different sizes, divided into different exercise areas, and any ships that entered this area would receive their attention, and when they saw the flag belonging to the northwest, and after the code word, the German warship simply handed over and let it go, and on Cheng Biguang's ship, there was an additional flag, a temporary agreement, and it belonged to the flag of safety.

With this flag, the Wutai Mountain entered the exercise area, and no longer worried about being injured by mistake, of course, Cheng Biguang also seriously inquired about the current exercise subjects, and got a relatively safe road from the German captain, hanging the flag, does not mean absolute safety, and really entered the area of the battleship salvo, 15 kilometers to 20 kilometers of range, even if the accuracy is not high, but it is really lucky, and was hit by the main gun of the battleship, less than 3000 tons of Mingshan class, even if it is an excellent all-rounder battleship, But it was still a small battleship, so that the battleship's main gun, with one shot, could sink him.

Fortunately, after touching the German battleship, it is not far from the position of Scheer, and they will generally form a loose, almost 200 nautical mile area, and the area from the Wutaishan to the Scheer is about 120 nautical miles at most, and the speed of the Mingshan class is about 4 hours.

When Cheng Biguang was about to arrive at the sea area of sea trials, Scheer was also observing the new aiming system, Scheer They have been trained for more than half a year, and the artillery second system has also been studied for half a year.

According to the results of the latest experiments, if all indicators are accurate, for a warship with a speed of less than 25 knots and high-speed movement, within 5 kilometers, 90% of the hits can be guaranteed, 10 kilometers reach 75%, and 15 kilometers reach 35%, it seems that the hit rate is declining, but for a high-speed moving ship, this is an amazing hit rate, even if the shell comes out of the barrel at the initial velocity of kilometers per second, and leaps a distance of 10 kilometers, at least 10 seconds. If you add resistance and use heavy ammunition, this time will be a little slower, and a ship running at high speed at 25 knots may go out for hundreds of meters, and it is normal for the shell hit rate to drop.

Compared with the previous hit rate, the overall hit rate has increased tenfold, and the most important thing is that the range can always be maintained at more than 12 kilometers. Take the British battleship as an example, the 13.5-inch naval gun, the ultimate range is 20,000 yards, but no one will be brain-dead to launch at that distance, 20 kilometers distance, whether it is optical or sensory, the error is too large to bear, even if it is a powerful British, at most, it is at a distance of 15,000 yards, that is, a distance of about 13 kilometers to shoot, strictly ordered to exceed this range, not allowed to design, that is a waste of shells.

But now, at a distance of 15 kilometers, the hit rate can reach this level, and if you put it on the battle line, this hit rate can be even higher, which is very amazing. The reason why warships want to seize the battle line is to ensure the hit rate, and replace a single hit rate with the range of group shots, so the navy's preemption of the battle line has entered the bones of the navy and is a skill that must be mastered. A single ship to achieve such a hit rate, or at a distance of 15 kilometers, is simply terrible for the Navy.

This is a great improvement, but the more he understands it, the less interested Scheer is in him as much as before, especially after paying attention to several tests, and even rashly entering the northwest exercise area, looking at the whole process of their entire test, he found that this epoch-making aiming system has a huge loophole, and this loophole is so big that no matter how optimistic Scheer is, he can only give up.
