Different people have different opinions on what drama is meant by fighting.

For submarine officers and soldiers under the sea, there are only two forms of war: one is to seize opportunities, and the other is to miss opportunities.

The "Kill Whale" returned to the cruising depth of 4 meters. Zhang Xuefeng asked his deputy Major Lu Hongtao to issue a combat order, and repeatedly read the combat order received by Caiwang several times.

It's true that the war is about to begin.

Zhang Xuefeng breathed a sigh of relief and threw a betel nut into his mouth.

For the soon-to-be Navy Colonel Feng, the decision to stay in the front-line combat force three years ago was his second major decision in his naval career besides partnering with Liu Haifeng.

It’s not that Zhang Xuefeng doesn’t want to live a stable and peaceful life, but he is unwilling to give up.

When Liu Haifeng left the front line and was promoted to the commander of the naval submarine, he invited Zhang Xuefeng to the submarine headquarters together and continued to be his deputy. The naval commander Lin Xiaolei also meant this. After all, Liu Haifeng and Zhang Xuefeng have been partnering for many years, and the two have a very close relationship. It is natural to let Zhang Xuefeng become the chief of staff of the submarine force.

After thinking twice, Zhang Xue was so arrogant that Liu Haifeng's invitation and decided to stay in the front line.

The two lived together for several years. Although Zhang Xuezheng did not explain the reason for staying, Liu Haifeng knew his partner's idea. Not only did he not force him, he also won the best opportunity for him: to serve as the assembly chief of the "Kill Whale, the hybrid attack submarine.

At the end of the year, Zhang Xuefeng went to Wuhan Shipyard to participate in the assembly and scraping work of the "Kill Whale".

This is a tradition of the navy. Any warship has an assembly commander from the navy during the installation stage to assist the shipyard in completing construction work and train the first batch of crew members. Generally speaking, the assembly commander will be the first ship commander, responsible for finding out the performance of the ship in the first two years of service and training qualified officers and soldiers. For any naval officer, Mu said that being able to serve as assembly commander is a very valuable opportunity. According to the unwritten rules within the navy, if an officer wants to be promoted to a general, he must know the construction work and must have the experience of serving as assembly commander. Lin Xiaolei, Zhang Weichang, Mu Qingyun, Dou Haizhi, Hua Jianfeng, Du Xinghua, Liu Haifeng and others have all served as assembly commanders, and Zhang Xuefeng is no exception.

Liu Haifeng's arrangement is exactly what Zhang Xuefeng likes.

In fact, Zhang Xuefeng is unwilling to be Liu Haifeng's deputy forever. It's not that he doesn't admire Liu Haifeng, nor does he have any conflicts with Liu Haifeng. It's just that he served as the chief of staff of the submarine force as Liu Haifeng's deputy, and he will not have much future in the future, and it will be even more unlikely to get more opportunities.

Only by working alone can Zhang Xuefeng have the chance to win his own general title.

At the beginning of the year of the Cong Dynasty, the "Drud Whale" was completed and put into service. Zhang Xuefeng led the first batch of officers and soldiers to join the battle sequence of the Republic's Navy by driving this attack submarine of the beneficial era.

The "Drut Whale" numbered "Yang Dagger" is the second attack submarine named after this name. It is also the first ship of the "Drut Whale" class, the third-generation hybrid attack submarine of the Republic's Navy. Compared with the previous "Dolphin" class, the "Drut Whale" class has a clear difference.

In terms of boat type, the "Killer Whale" class is the first submarine to adopt the "flat-change-section elongation boat type". Its cross-section is not a standard circular, but an elliptical. Although this design brings a lot of trouble, such as the reduction in the strength of the pressure-resistant shell, the thickness and the strength of the reinforcement ribs must be increased, thereby greatly increasing the structural weight; for example, the wet surface area of ​​the circular cross-section is much larger than that of the circular cross-section, thereby increasing navigation resistance. To achieve the same speed, a propulsion system with greater power must be equipped. However, this change

The benefits of transformation are more obvious. For example, the draft of the submarine is reduced, so that the submarine can operate more flexibly and freely in the shallow water near the sea without affecting the deep-sea performance of the submarine; for example, the wide hull provides more choices for the preparation of sonar, torpedo launch tubes and other equipment, and enhances the detection and attack capabilities of the submarine. Fundamentally, the "Killer Whale" class's first-time use of a circular cross-section hull is not too laughed at from the factors mentioned above. The root cause is only one, that is, its propulsion system.

The full name of the propulsion system used by the "Killer Whale" class is "superconductive magnetofluid spiral propulsion system." It is generally called "magnetic fluid propulsion system" or "superconductive propulsion system. Compared with traditional propulsion systems, the biggest feature of the "superconductive propulsion system" is that there are no moving parts and there will be no mechanical noise and cavitation noise. This alone is enough to make the "superconductive propulsion system" favored by submarines. Whether it is a seven-blade large-side inclined propeller or a mercury jet propulsion system, in essence, they all make the submarine advance by the reaction force generated when the pulp blade rotates and pushes seawater. When the pulp blade rotates, it will not only produce mechanical noise, but also produce more harsh cavitation noise. Among the noise generated by submarines, mechanical noise and cavitation noise account for more than 70%. If these two noise sources can be eliminated, the submarine's mute performance will reach an unimaginable height.

When designing, the noise level of the "killer whale" level was set to be clever decibels.

This is not the noise level when cruising low-speed silent cruise, but the noise level when tracking the target at the speed of the junction.

You should know that when advancing at the speed of the knot, the noise level of the Dolphin class is close to 0 decibels, and the noise level of the first-generation fully electric attack submarine in the United States is around decibels. If the "Druddle Whale" can reduce the noise level to decibels, not only no submarine can match it, but even all existing anti-submarine detection systems will be eliminated.

The length of the "superconducting propulsion system" exceeds the thug's strength meter and is less than 2 meters in diameter. If the traditional layout is adopted and only one propulsion system is equipped, the propulsion system will run through the poison submarine and be set on the central axis of the submarine, which will have a catastrophic impact on the layout of other cabins. More importantly,"

When the construction of the No. 1 was started, the power of the "superconductive propulsion system" was still non-sexual... The maximum is not enough to achieve the maximum submarine speed required by the Navy, and the propulsion power of the thug kilowatts is also required to achieve the maximum submarine speed required by the Navy, while trying to control the displacement as much as possible. In this way, only a Zhen propulsion system can be equipped. The ideal solution is naturally to symmetrically configure the system on both sides of the central axis of the submarine. It is precisely because the "Drowned Whale" had to adopt an elliptical cross-section hull. It also lengthened the length of the straight section hull, and set the water inlet and outlet of the propulsion system at both ends of the straight section respectively.

Because the reliability of the "superconductive propulsion system" belongs to "new things" remains to be verified. Before the construction of the "Killer Whale" class, the Navy has built a thug test submarine, specifically used to test the performance of the "superconductive propulsion system", the "Killer Whale" is also equipped with two sets of backup propulsion systems, one is a shrinkable mercury jet propulsion system with a propulsion power of Tunkou kilowatts, and the other is a two kilowatt directional drive system.

In order to build the best submarine in the world, the construction cycle of the "Druddle Whale" lasted for a long time.

Tests before formal service showed that the silent standard of Yanran "Dragon Whale" did not fully meet the design indicators, and the noise level at the time of the festival was around decibels, but some performances even exceeded the design indicators, such as the noise level during the 8th cruising was only decibels. The Navy required a blade decibel. More importantly, the performance of the "Dragon Whale" was enough to stand out.

It has powerful silent performance, and must also have advanced detection systems and powerful weapon systems.

As the first attack submarine developed by the Republic's Navy in the form of a "horizontal combat platform", the other sexes of the "Druddle Whale" will never be much worse.

After adopting an elliptical cross-sectional hull, the side sonar array of the "Killer Whale" increased from licking to 4, which were located on the upper and lower surfaces of the left and right sides of the hull, so that it has the ability to "cross detection" in one direction, which can greatly improve the lateral performance of the passive sonar array. By integrating the detection units of the two groups of sonar arrays in the same direction, each group of base arrays has a mouth pound. The detection units can more accurately determine the distance and orientation of the target. The biggest trouble caused by this is that it requires a more powerful computer to complete the data analysis work. For this reason, the "Killer Whale" not only adopts

The central intelligent fire control system controlled by neural network computers also adopted high-speed commercial computers for the first time. Although the stability, loss resistance and adaptability of commercial computers are not as good as military computers, their computing power is significantly stronger than that of military computers. It is not uncommon to use commercial computers in weapons and equipment. As early as the beginning of the century, the United States used commercial computers on the Qishi series of fighters. It used commercial computers on submarines and was responsible for the most important fire control computing tasks. This is the first time. After all, submarines have great special characteristics and have higher requirements for stability and safety.

In terms of active attack sonar, the "Drut Whale" still adopts a traditional layout and installs an active and passive multi-purpose attack sonar on the boat. What's better than the "Dolphin" is that because the "Drut Whale" uses an elliptical cross-sectional hull, the sonar cabin of the boat is also rounded, and it cannot use a spherical sonar array, but an oval sonar array. Compared with the traditional spherical sonar array, the oval sonar array has slightly worse detection capabilities in the vertical direction and stronger detection capabilities in the horizontal direction. Thanks to the advanced passive sonar system, the lack of performance in the active attack sonar does not have much impact on the detection performance of the "Drut Whale".

In addition to the two main sonar sets, the "Drut Whale" is also equipped with multiple sonar systems for measuring and mapping the seabed terrain, avoiding mines, and conducting underwater directional short-range communication. If it floats on the Shanghai surface, the "Drut Whale" can also use multi-purpose radars to explore targets. However, hybrid submarines with unlimited endurance are mostly active under the sea surface, and even if they need to exchange information with the outside world, they will remain at the depth of the periscope. Therefore, the radar on the submarine does not have much effect.

In terms of attack weapons, the "Drucian Whale" took the lead in adopting the "modular" design concept.

In addition to the 6 3-millimeter torpedo tubes arranged on both sides of the ribs, there is also a section between the command cabin and the torpedo cabin that is specially used to carry a weapon launch system. When performing different combat missions, different weapon launch systems can be carried in this section. For example, when attacking ground marks, a system carrying a vertically launched hypersonic submarine-launched cruise missile can be equipped in this section; when performing sea control missions, a set of vertical launches for carrying a port.

The hypersonic anti-ship cruise missile and heavy torpedo launch system is launched horizontally, and the angle between the hull and the hull is tens of thousands of degrees when it is discharged; when performing a blockade mission, a water ammunition dispenser carrying a good mine is carried in the cabin. If necessary, the cabin can even be replaced to allow the Ming armed frogmen to enter and exit the "wet cabin" at the same time. If the weapon launch system is carried according to the sea-making mission, the "Druddle Whale" has an ammunition load capacity exceeding the blade strip, and the torpedo's boat is more muddy than the "Dolphin" class.

For a large submarine with long thugs, Wumi, wide thrust, water-draining, submarine displacement, and underwater displacement, while the "Dragon Whale" has strong performance, the cost is also so high that the navy is difficult to absorb. The purchase unit price it previously looked at was about 800 million yuan and pharmacy US$100 million, which is twice the "Dolphin" class. Although the price will drop by about 500 million yuan after large-scale procurement, the price will drop by about 500 million yuan, but when the Navy focuses on building an aircraft carrier battle group, the purchase volume of the "Dragon Whale" class thru will definitely not be too large.

After the first batch was completed, the Navy made an order for the second batch of ships to purchase thugs that year, and paid 4. According to the Navy's plan and the Ministry of Defense's annual military budget, the construction time of the second batch of "Killer Whale" class is likely to be extended to more than a prosperous month, and the high construction costs are shared by extending the construction time.

The reason for the high cost of "Killer Whale" is not its novel design. After all, no matter how novel the design is, it will not have much impact after entering the engineering stage. In addition to the investment in the "superconductive propulsion system, and the cost of advanced fire control systems, the main reason is that the materials used by the "Killer Whale" are too expensive.

In order to achieve the design indicators of the maximum submarine deep milk rice and the maximum submarine speed blade festival, the "Killer Whale" had to give up the high-strength steel that has been used to build submarines and choose high-strength alloys. According to the design indicators, high-strength alloys account for the submarine's structural quality. That is to say, "the "Killer Whale" class needs to be stewed about high-strength alloys. Even if the Navy can buy high-strength alloys at a cost price, it will have to pay approximately 10,000 yuan of market price of B-yuan high-strength alloys per ton.

Later, when the Republic promoted the "improved" submarines of the "killer whale class" to the outside world, it used paper-reducing performance indicators mainly submarine depth indicators, and adopted a simpler fire control system and other methods to use high-strength steel, which reduced its cost to about 100 million yuan. Because of the low cost and the "advertising effect." Therefore, the Republic's Navy canceled the last batch of "killer whale" purchase orders and switched to a batch of such submarines specially used for export.

From a technical point of view, the "Killer Whale Class has achieved great success.

From a business perspective, the "killer whale" class made the most serious mistake, just like the "sea wolf" class in Kai'an at the beginning of the century.

Although in the eyes of the Ministry of National Defense officials, only weapons that can be used are good weapons, in the eyes of naval officers and soldiers like Zhang Xuefeng, only by being able to kill the enemy and preserve their own weapons is good weapons.

There is no doubt that the "Drud Whale" is the ideal submarine in Zhang Xuefeng's mind.

After completing all the test work in the early stages of service, the "Drut Whale" began to carry out combat readiness missions. From June to the previous year, the "Drut Whale" carried out three combat readiness patrol missions, each of which lasted more than the "Dorphin" class that had been in service for many years. In these three missions, 2 times were accompanied by strategic submarines in the first island chain from the Qianwu Islands, passing through the Japanese archipelago, Ryukyu Islands, and Taiwan Island.

The Philippine islands and Indonesian islands finally arrived in the waters west of Singapore to carry out strategic alert patrol missions, with nothing to say. In addition, the thugs performed a "hunting" mission alone, first lurking Wu Tian near Guam, monitoring and tracking several US Navy submarines, and then heading to the Hawaiian Islands. "Participating" the US Navy's "Winter Storm Book and Military Exercise, and discovering the latest attack submarines of the US Navy.

This mission made the "Drud Whale" show its face in the navy.

You should know that according to the noise data brought back by the "Killer Whale", the noise level of the new American submarine at 8 knots is only decibels, and the noise level at 24 knots is better than that of our decibels, and the silent performance has been significantly improved, even better than that of the "Dolphin" class.

When the Orca Whale returned to the submarine base from Hawaii, four other sister boats also joined the naval combat sequence.

According to the Navy's regulations, after performing three months of combat readiness patrol missions, the submarine officers and soldiers will obtain the Litian holiday in the form of a rotation. Here, the thug is Jin and sail again after the month.

Zhang Xuefeng did not apply for leave, and the captain had to follow the submarine at any time.

Fortunately, the Navy fully considered the basic needs of "workaholics" like Zhang Xuefeng. Not only did it arrange welfare housing for him at the submarine base, but its families were also allowed to visit relatives after the submarine returned to the base.

In the late morning, when the "Drudge Whale" is about to complete the maintenance work, Zhang Xuefeng received a new order.

Preparing to thug, he left Hong Kong a few days ago.

There is no doubt that this is a combat order, not a combat readiness patrol order.

Any captain knows that this order means that war is about to break out.

Although the maximum self-sustainment of hybrid submarines such as the "Kill Whale" is all about the thug. After all, the crew's physical strength, endurance and energy are limited. No matter how good the psychological quality is, people will have problems living in a closed environment for a long time. According to the advice of psychologists, the submarine's continuous activity time should be controlled within the sky, and it is best not to exceed the sky. Only when they have to be forced can it be extended to Litian. After several vicious accidents, the Navy attached great importance to the advice of psychologists and made clear regulations in Lilan Year. The normal combat readiness patrol time must not exceed Litian. In fact, any submarine will leave a backup supply of about the old sky.

In other words, follow the thug and Zhuotian.

On the night of June Blade, the "Drud Whale" left the submarine base of the South China Sea Fleet and embarked on a journey of Jiangxi.

But Zhang Xuefeng never thought that this mission would be so troublesome.
Chapter completed!
