## Background

As one of the oldest civilizations, the history of Celestial Navy is also long: as early as 2000 years ago, at the end of  the Spring and Autumn period, there were detailed records of vassal states going north to attack other countries by sea. Although this attack ended in failure, it did not affect the development and progress of ancient Celestial Navy. After all, this "little" failure is not worth mentioning under the urgent need of expandingup the territory; although the boundless and vast ocean can not go deep, the rivers and lakes in inland should not be any obstacle.

Since then, in order to meet the needs of fighting in the south of the Yangtze River where the water network is dense, the southern vassal states have established their own naval forces and caused a series of battles. As the wheel of time roll over, a thousand years later, the compass has been popularized in southern Chu, and a series of new technologies such as watertight compartment, launch with slipway, and pointed bottom have been put into practice. Considering its inherent military and economic demands, the southern Chu navy has become the most powerful water force in the East after a hundred years of development, which can also be said to be the strongest in the world at that time. This fierce and huge sea forces, and for decades invincible.

However, as time goes into modern times, the Celestial Navy is gradually dissatisfied with the stereotyped rules of the old warships: complicated variant names, overlapping task positioning, and disharmony caused by the lack of conciseness in the documents is unbearable to the high-level, because it often means chaotic management and implementation and excessive redundancy in practice. In order to improve this situation, after many discussions and comparisons, Celestial Navy has chosen the standard name of warship type translated from Western words. In this way, while ensuring the conciseness, it can also more accurately compare our warships of the same type with those of potential rivals.

It was during this period that torpedoes, one of the new naval weapons that subverted the tradition, were born. Although these mobile underwater bombs powered by compressed air were simple and primitive, they did enable small ships to attack large enemy warships without carrying out "close combat". The result of this idea was to torpedo boats, whcih attack by carrying and launching torpedo. The cost of this kind of small craft with high speed is low, but under the reasonable command and deployment, it can not only harass the naval battle with its maneuverability and high lethality, but also shuttle through the complex sea area to intercept and kill the high-value large-scale enemy units. Faced with such a small threat, the navies of all countries are trying to find a way to deal with it.

The years before and after the war may not promote the overall progress of human civilization, but it will certainly promote the practical process of basic research in the fields of science, engineering, biochemistry and so on. Within a few years, the United Kingdom navy and the Celestialnavy have designed and built their own "torpedo boat hunter". Their common characteristics are steam power, displacement of hundreds of tons, and low cost. The difference is that, unlike the Celestial navy, which only equiped with two 96 mm naval guns, the United Kingdom navy provided one 76mm naval gun and three 40mm rapid-firing  guns for this type of warship. At the same time, a 457mm torpedo launcher is also equipped, which makes it have the ability to hunt and kill torpedo boats efficiently, and also has the ability to threaten large enemy ships. In order to  "learn from foreigners to counter foreigners" , this design idea was also adopted by Celestial navy soon. For quite a long time, this type of warship was called "torpedo bast chaser" by Celestial navy, both in documents and in daily life.

From an objective point of view, this should be regarded as the renewal of surface ships that use torpedo weapons; and the emergence of torpedoes also makes another naval ship officially enter the stage of history: submarine. The combination of mature submarines and torpedoes expanded the scope and form of naval warfare from shell flying on the sea level to explosive delivery on water and underwater. In the period before missile technology, even submarine launched missile technology, torpedo was the only common weapon that could be used normally in "submerge" state.

After the European war, the report submitted by the general officers of the general staff office made clear the terrible part of the submarine weapon: during the war, the merchant ships of the Triple Entente suffered a lot of losses, and even some Celestial ships were hit by mistake. Therefore, both the weaponary department and the Ministry of military agreed to develop special ships for counter submarines, and at the same time, refit the ships that can also perform such tasks. The development of professional submarine chaser  began at this time. With the long-term naval armament competition going on, the result of the latest generation is the finished product of 1C642 project, which is named "wupeng submarine chaser" as mentioned in the previous profile.

However, this is not enough: one of the advantages of submarines is that they only need underwater space. Although they have to travel thousands of miles along the current and tide, and be careful of the undercurrent during navigation, the confined space which is design to resist pressure does not need to pay attention to the violent violent storm and the huge waves on the surface. The design requirement of the submarine for thousands of miles can also minimize the dependence on logistics. For this reason, conventional attack submarines using torpedoes or missiles do not have to care about the wide area combat environment. As for Wupeng, or submarine chaser, is a small vessel after all, and its design and use environment is shallow water or at most continental shelf area. Even if there are many subgrade and offshore support, most of the time they are only responsible for the boundary and internal affairs of the defense system of the southeast island chain; in this range, the advantages brought by the small boat type dominate. However, in ocean operations, the requirements for seaworthiness and high firepower are beyond the capacity of the small Wupeng. As mentioned in the previous profile, even the latest Wupeng needs to be mounted on large vessels in both physical and informational aspects before it can be used in the ocean. Naturally, those small boats before this can not even achieve such "feats".

Therefore, the research and development of large-scale anti submarine vessel started. It is worth mentioning that even though the Celestial Navy, which always takes the lead in the annual military expenditure, seldom haggles over open project and building factory, it does not mean that they like to spend unjust money. Excpet fort the national investigation department, the Ministry of discipline inspection and supervision, and the ethics committee, which will make the relevant people concerned.The military department and the weaponary department naturally know what they are here for and why they are here. Moreover, considering the preferential treatment given to the navy by the other major services, the navy can't let them be laughed at by their "brothers".

Because of the huge amount of resources needed to redesign a large-scale anti-sub only ship and put it into mass production or even formal service, Celestial navy hopes to find a suitable way of improvement in existing ships, so as to make it have anti-sub capability, without having to push back the existing construction and service process of such ships. There is no doubt that torpedo boat chaser is the most suitable base for anti-sub. The balanced cost, volume and navigability make them the most suitable choice. Compared with the torpedo boat chaser, the first batch of submarine chaser only replaced two triple torpedo launchers and a mechan gun in the tail with four depth charge launchers and two depth charge slide rails. This method of refitting existing ships is really convenient and fast, but it can only be said to solve the problem of whether there is one. After all, the common problem of torpedo boat chaser and submarine chaser is that their combat purposes are too limited. If a fleet is to be allocated to both torpedo boat chasers and submarine chasers, it will inevitably lead to the increase of fleet size and redundancy.

As a result, everything that followed became reasonable. The Celestial navy put forward the design requirements of the new multi-purpose warship: it could not only have enough anti-sub capability, but also be competent for the work of torpedo boat chaser. Of course, this can not be achieved on a light warship with a displacement of only 1000 tons. The corresponding system components and resources used on the ship are over 1000 ton.

Among the several drafts put forward by the science and technology industry of naval vessel, the lightest design also requires a displacement of 2000 tons, and the cost of a single ship is naturally greatly increased. However, considering that this is the result of combining the two combat purposes, the total cost in the navy system after service is reduced, so the Celestial navy is happy to accept it. Moreover, in view of the fact that such warships will no longer be used for single purpose in the future, and the targets they are "chasing" are no longer just torpedo boats or submarines, Celestial navy renamed them "destroyers".

...

As time goes by, many years later, Jimeng class destroyers, which were once placed high hopes, even named after the rain god, are already very old. As the Celestial second generation missile destroyers, they should really return to their hometown with honor, whether the "Hometown" is a museum or a dismantling factory. On the day after "Jimeng", the first old Jimeng class destroyer, retired in Mingzhou port, she crossed thousands of miles and "reincarnated" to another Jimeng II class destroyer that had just been delivered. This was also the first time in the history of the Celestial navy that the name of the retired warship that was removed by the Navy Department on that day was re granted to another warship the next day.

The R & D Progress of Jimeng II class destroyer was quite slow at first. However, with the change of the world situation, some defects of Jimeng I class (i.e., the second generation of Celestial missile destroyer and the old Jimeng class) made it unable to meet the needs of the Celestial navy itself and foreign countries. Therefore, the research and development speed of Jimeng II in the middle and later stages was greatly accelerated under the urging of the navy, trying to speed up as quickly as possible to complete the design and put into mass production. However, even though there was a bit of rush and rush, the engineers and technicians of the 701th science and technology industry of naval vessel, still created a nearly perfect destroyer.

The Jimeng II class destroyer with the design project number of 1D102 follows the unique long stern ship type from the old Jimeng class destroyer, which still maintains good stability under the condition of ensuring more space in the ship; the lower bow reduces the center of gravity of the whole ship, and the overall length width ratio is relatively small, which greatly improves the seaworthiness of the whole ship. The drawback is that such a low bow is easy to be washed clean by the joint efforts of the sea and sky under bad weather conditions, and the mechanical equipment, weapons and even personnel on the bow will be blown to the sea and fly into the sky. Even if the designers add a large extend at the bow for 1D102 to avoid the possibility of the whole ship being splashed by the bow waves when sailing at high speed, and  reinforces or reshapes numerous structures on the bow, it is still difficult to completely eliminate such problems when encountering big waves. In addition, because it is easy to get into the waves. Theoretically, the maintenance period of 1D102 is shorter than that of other warships, especially the corrosion rate of the bow is much higher than normal. But, thanks to tens of thousands of engineers and workers in hundreds of docks and shipyards along the coast and in the north, east and south sea areas, many "rain gods" on the ocean are still intact and complete in equipment an personnel, despite the severe hydrological and meteorological impact that not occur even in a hundred years for dozens of times.

Compared with aircraft carriers and battleships, the overall size of this type of destroyer is not large; however, according to the most basic requirements of warships, the science and technology industry Institute still sets out a part of the displacement of thousands of tons to be used for protection of key parts. For example, the bridge, the combat command office, the power cabin, and the ammunition depot are all arranged with double 64 mm composite armor plates. The thickness is just right: incoming small caliber shells cannot penetrate it, and light anti-ship missiles are easily detonated after penetrating the first armor plate. For one of its opponents, the Allied light destroyer, its double-layer armor plate, which can make it face a dilemma. Under normal combat distance, 127 mm standard SAHPE can't break it down, but switching to APFSDS will lead to overpenetrate, which makes the aftereffect very low.

The overall structure of the destroyer is a traditional hybrid skeleton structure, with a double bottom. There are 36 watertight or oiltight partition bulkheads in total. Among them, 24 watertight bulkheads divide the whole ship into 25 watertight compartments. In addition, the additional fuel cabin and other reserved empty cabins at the bottom of the ship ensure that 1D102 has considerable survivability. On this basis, 701th science and technology industry institute has arranged quite balanced weaponry and other layout construction for it, among which the most prominent is the "lanterns" set on both sides. As one of the painstaking efforts of numerous research institutes and enterprises in Celestial Empire to put them into practical use, these lantern like devices are actually remote microwave power transmission equipment units; by the way, the one before this that can get this honor and is put into the lantern by all levels of institutes in Celestial Empire is still the aerial automatic remote maintenance unit that has been used so far.

The lantern of these ships is designed as the port of power supply network of fleet. It can not only meet the energy support and dispatching problems between large warships and small ships, front and back edge of battlefield, but also connect local wireless transmission network when the ship is parked at its own port, and meet the daily maintenance work of the ship without consuming energy in the ship. However, as one of the research and development units of wireless power transmission, the Husu electromechanical group did not stop. After several attempts, they successfully added laser communication function to the latest batch of "lanterns" to meet the silent communication needs in complex sea conditions. Of course, like the Prism Tanks of the allies, these "lanterns" can also emit visible light, and the Celestial navy often uses these lanterns to create a festive atmosphere at night on holiday days. But of course, once the fleet sets sail or the ship is in combat condition, the adjustment options for the visible light band will lock itself after double encryption.

In terms of power and energy equipment, a complete set of integrated electric propulsion equipment is carried in the 1D102 , which is powered by four gas turbine generators and two diesel generators produced by Husu electromechanical group which drives the motor to rotate the propeller and propels the ship to a maximum speed of 31 knots. The advantage of integrated electric propulsion is that it reduces a set of power equipment and variable speed equipment, and saves a lot of valuable space on the ship. Besides, due to the existence of microwave power transmission terminal, even if the whole ship loses power, as long as there is a motor and a "lantern" still not invalid, then the whole ship can still withdraw from the combat zone at low speed, or even continue to fight.

The electronic equipment of the 1D102 project is also provided by Husu electromechanical group. However, in addition to the military projects such as phased array radar, the mass production of other electronic equipment also includes several private enterprises. Compared with the old Jimeng, which was designed and finalized earlier and only passive phased array radar can be used, the 1D102 project carries the dual band phased array radar system with the best comprehensive performance in the equipment sequence of the Celestial navy. The Celestial navy even granted the code of "natural moat" for the shipborne air defense and antimissile system based on this as an exception. However, considering the assembly cost and ship specifications, the project actually carries a simplified version with only two large and two small "shields" in total. In the system, there are two "γ" band channels responsible for long-range wide area alert, and four "ε" band channels responsible for short-range tracking (each big shield has one γ band channel and one ε channel, and each small shield has only γ band channel). Thanks to the good structural design of high bridge and low chimney, the two small "shields" in the rear are not covered by any shelter, and also have a considerable search range. In the actual evaluation, under the common sea conditions in the Pacific Ocean, the "natural moat" system has an air search range of 550 km. It can track 256 air targets at the same time, lock in 48 of them, and guide 18 ship to air missiles from itself or friendly ships to attack the six most threatening targets at the same time. In addition, the ship is also equipped with a three-dimensional air surveillance radar, which is nicknamed "thousand layer cake" by navy soldiers due to its shape, and a "citrus" sea search radar which get this nickname also by the shape: the former works in the "δ" band and has an air detection range of 310,mainly responsible for the usual air alert tasks .After all, the phased array radar has a limited service life, and it is impossible to continuously start up for a long time. In combat condition, the task of "thousand layer cake" has become to find out and make up for deficiencies, and assist the "natural moat" system to carry out combat tasks. As for the "citrus" as a sea radar, it works in the "ε" band, with a sea detection range of 82.5 km. It is responsible for guiding the main gun fire, and taking on the navigation and guidance task in the complex sea area.

When it comes to attack guidance, the warship's weapons and equipment are naturally worthy of great attention. The main gun of 1d102 project is a 112 mm plasma cannon, which is provided with technical basis by the 2nd Academy of Aerospace Research in Capital. And  the mass production is responsible by the south Mo second heavy machinery workshop of Fenghou group. The special loading system and plasma reactor of this kind of gun are manufactured by the south Mo second heavy machinery workshop and the special reactor workshop of Hudong respectively. Here, we have to mention one of Celestial scientific crystallizations- "plasma reactor". The Seventh Research Institute of the Celestial Academy of Sciences is responsible for technical research and theoretical support, and Hudong special reactor workshop is responsible for design verification and industrial manufacturing.

As the only reactor that can be compared with Celestial mini fusion reactor which is widely equipped in Fusion Gloriette and large warships, the plasma reactor, which is also the product of Hudong special reactor workshop, is the necessary supporting facilities for most of the common plasma weapon in Celestial arsenal. The reactor can inject the energy input from the active system into a special medium confined by magnetic field, which can generate high-energy plasma with high efficiency and continue to charge it to the energy density close to the quark-gluon plasma. In addition, the reactor can maintain stable plasma ammunition output with the help of special "loading" system. Most of the plasma cannons, including Zhuque and Jimeng's main weapons, obtain ammunition from the adaptive reactor. As an exception, Zhurong adopted the separation scheme between vehicle and reactor because the space and resources on the vehicle could not afford even the modified plasma reactor. In the factory, the output of plasma ammunition was packaged into sufficient quantity in advance, and then like other ammunition supplies, transported by the logistics line which is invisible in the field command system; Baihu use the new technology of atomic suppression field to create a powerful siege plasma bomb, but the resources that suppression field needs and the results, which makes the action principle and killing efficiency of Baihu main weapon different from most plasma weapons, and does not need the support of plasma reactor.

The 701th science and technology industry of naval vessel has many considerations in selecting plasma gun: In addition to its rich technical foundation and completed technical system, what is more important is that it can cause considerable damage no matter whether it penetrates the opponent or not. The existence of "reactor" greatly reduces the energy consumption of plasma cannon. In contrast, although the railgun has excellent penetration depth, it is easy to cause over penetration and poor aftereffect. Even if a new type of railgun shell which is still in experimental stage is used, the active system on the destroyer is not enough to effectively drive the corresponding high-power railgun.

However, the subsequent problem is that even though the south Mo second heavy machinery workshop is fully powered, it still lacks many production resources to complete so many orders at the same time. Compared with the limited number of navy orders, the orders for 128 mm plasma tank guns from the army have exceeded the production limit. Such a situation even forced the third and fourth launched 1D102 project ships to use old gunpowder guns temporarily during outfitting, so as not to fall into the embarrassing situation that no guns were available. Therefore, a general of the navy also sent a special telegram to question. Under the pressure of many parties, south Mo second heavy machinery Workshop had to hand over part of the production tasks of 128mm plasma tank guns to its brother enterprises, while it was making full efforts to produce naval guns needed by the navy. It was not necessary for the brother enterprises to see that they could obtain the most benefits. Unfortunately, the production capacity and license certificate of naval gun and its supporting equipment were not possessed by every factory.

Then there is the embodiment of the core combat effectiveness of the 1D102 project, the "Xingtian" vertical launch system. As a new upgraded version of the old vertical launching system, the most important feature of the "Xingtian" system is its slide type reload design, which enables it to reload the launch box at a very high speed in combat. But this is only limited to light missiles. The reloading speed of medium missiles is still relatively slow, while that of heavy missiles is like most destroyers, this type of ship does not have the capability of self loading heavy missiles, and needs to dock or be supported by a supply ship. There are four sets of 20 unit vertical launching system in 1D102 project. However, even if it has a high generality, the designers still suggest that the two groups of ten unit vertical launching system in the bow should be used for anti-air and the two groups of stern to be used as anti-sub missile launcher.

4D-6 light ship-to-air missile is a new generation of short-range ship to air missile developed by Celestial 2nd Academy of Aviation Research. Although the short-range ship-to-air missile is often neglected because it is in the awkward position of "making up the firepower gap between the close-in weapon system and the medium range ship-to-air missile", the Celestial navy insists on upgrading this kind of missile at a normal speed. The total weight of 4D-6 is only 85 kg, with a maximum range of 21.5 km. The 4D-6 adopts the radio and terminal infrared-ultraviolet composite guidance mode. With its excellent comprehensive performance, it has become the absolute pillar of Celestial navy's medium and short-range air defense. In actual combat, 4D-6 light ship-to-air missile, which is endowed with the name of "Cloud Piercer", has an extremely ideal damage effect on small air units. Even though it is relatively weak against heavy air targets due to size limitation, thanks to the rapid loading system, Celestial navy can often fire a large number of light missiles at the target, so as to submerge them in quantity or take other countermeasures to target these large aircraft.

In the aspect of anti submarine task, due to the strength of the red navy's unfathomable submarine force, the 701th science and technology industry of naval vessel spared no effort to strengthen the anti-sub capability of this type of ship in accordance with the nearly morbid anti-sub requirements of the Celestial navy, and equiped the "Shark Vanquisher" medium-sized anti submarine missile from 2nd Academy of Aviation Research for it. The reason why 4C-7 is given such a loud name is because of the great pressure brought by the "Akula": they are worthy of deep-sea hunters with double-layer titanium alloy hull, and the Celestial navy is almost racking its brains to find any way to counter them. Like the Allies, the Celestial navy also found that the small torpedoes carried by light anti-sub missiles could not effectively kill these deep-sea sharks. Compared with the Allies who used the simple and crude way of hitting the face with depth charges, the Celestial navy chose to continue to develop the next generation anti-sub missiles. "Shark Vanquisher" is much larger than its predecessors: compared with its "father", which carries 320 mm small anti-sub torpedo, the "Shark Vanquisher"'s warhead is a 448 mm medium-sized torpedo. After all, only in this way can it have enough power to deal with the thick skinned dark red "sharks". In addition, in front of the bridge, the warship is also equipped with a 128 mm depth charge launcher of 16 unit anti-sub rocket with archive number of 4C-5. The rocket depth charge named "Whirlpool Creater" seems to be out of date with low operational efficiency. However, considering its extremely low operating cost and wide operational task, the equipment can be used for both anti-sub and deal with surface targets, so the equipment is finally retained.

In the bow of the warship, the designer also installed five decoy torpedoes to launch the "Chirping Cicada" decoy torpedoes developed by the 716th Naval Weapons Research Institute. These decoy torpedoes, which simulate the water waves, magnetism and audio characteristics of friendly warships to attract the enemy's lethal underwater attack objects, perform well in the actual test, which can be described as this type of decoy torpedoes another magic weapon of destroyer.

As mentioned above, the Celestial navy still named this ships after the rain god Jimeng. Although compared with their predecessors, the new generation of "Jimeng" almost surpasses in all aspects; however, everything in the world is not immutable. With the world situation becoming more complicated, Celestial navy thinks that the threat of "Akula" class submarines and other imaginary enemies has been underestimated in the past several discussions After repeated consideration and analysis by the high-level personnel and fierce discussions between the weaponary department and the general staff office, they finally decided to adjust the procurement plan: most of the follow-up procurement of Jimeng II was adjusted to anti submarine variant. These Jimeng II, which have been adjusted by the focus of combat mission and equipment system, are also known as type B or anti-sub variant. They have cancelled the equipment of "thousand layer cake" air surveillance radar and "natural moat" phased array radar, and only reserved the "citrus" sea search radar, but still reserved the configuration space of phased array radar in case of emergency. The "Whirlpool Creator" rocket depth charge launcher behind the bow was replaced by a twin 40 mm auto cannon. This is because the operational efficiency of the anti-sub depth charge is too low, and the ammunition takes up a lot of space. Bseides, in order to better carry out the anti submarine combat task, an additional synthetic aperture sonar is deployed in the bulbous bow of anti-sub Jimeng, and a towed line array active-passive composite sonar is added at the stern of the ship.

Benefit from the wide application of multi-stage modular construction technology, the construction speed of Jimeng II was amazing; and their first appearance was in a conflict in the "high seas" somewhere in the South Pacific Ocean. Facing of the incoming Allied fighters, the standard Jimeng II with the board number ██ almost emptied the ammunition reserve of the whole ship within an hour. Even though it was hit by three laser guided bombs and led to the power failure of the whole ship for more than 10 minutes, it still achieved the glorious record of shooting down seven fighters, which provided a "sunshade" for the second torpedo squadron of Empire of the Rising Sun, and finally achieved a good output environment assist the fleet it belongs to and eventually held out until a Celestial task fleet arrived in the combat zone.

After the end of "the battle", the supreme Defense Council of the Allied forces agreed with the assessment of the United States Navy report that a single Jimeng II can open at least 20 anti-air fire channels under the extreme state. Therefore, it is not recommended that any air force attack these warship and its fleet without numerical superiority or electronic suppression.

## Notes from the Field

Battlefield reconnaissance has revealed at least these facts about the Jimeng Destroyer:

**Reincarnation** - The present Jimeng destroyer is a completely upgraded version of the old one. The comprehensive combat capability of the new Jimeng is far better than that of her predecessors.

**Furious Storm** - It is said that the wind and rain will inevitably blow wherever Jimeng goes, and so do some standard Jimeng destroyers. They are equipped with a variety of weapons and can "call on the wind and rain" to achieve a comprehensive attack on surface, underwater and air targets.

**Depth Hunter** - Most of the subsequent batch of mass-produced Jimeng are focus on anti-sub. The "Shark Vanquisher" anti-sub missiles carried by them can effectively attack all types of submarines. No matter what the opponent relies on - solid hull or small size, they can not survive from Jimeng's hunting.

**Mantis and the Cicadas** - The Jimeng destroyer is equipped with a set of decoy torpedo launcher, which can induce the incoming torpedo to change course and create more tactical opportunities while ensuring the safety of the ship.

**Wave Strike** - The higher maneuverability allows the Jimeng Destroyers to choose to avoid some sudden hostile main ships, so that the fleet will not suffer meaningless losses.
