March 28, 2782 (1941), Guangxi Province, Haiphong Shipbuilding Industry Company.

After the establishment of the new China, Qinzhou and Lianzhou in the former Qing Dynasty were not assigned to Guangxi, but the two places were merged to set up Lianzhou City, which still belongs to Guangdong Province. In fact, in the early days of the Datu Dynasty of the original time and space, this land was also from Guangdong, and later it was assigned to Guangxi for the needs of the form of aiding Vietnam.

If this is the case, then the original plane of Guangxi is the same as the Ming and Qing dynasties, there is no access to the sea, what can be done?

It doesn't matter! Not on China's side, but outside China!

After the Sino-French Annam War, China seized half of Indochina, so our beloved President Boon Duc Si waved his pen and assigned seven counties of Vietnam, including Haiphong and Quang Ninh (Vietnam's province is equivalent to a county), to Guangxi Province, so Guangxi also had an outlet to the sea, and Haiphong Port, an important port, also became Guangxi's maritime transportation hub.

Haiphong Shipbuilding Industry Company, commonly known as Haiphong Shipyard, is the largest shipbuilding base on the Indochina Peninsula and one of the five largest submarine manufacturing bases in China. This shipyard was completed and put into operation in September 1918, and after 20 years of development, it has become a large-scale shipbuilding enterprise, with the ability to build merchant ships below 150,000 tons and warships under 50,000 tons. However, their most well-known and mainstream product is the submarine.

Today, at the pier of Hai Phong Shipbuilding Industry Company, a modest handover ceremony is underway. Two new submarines have completed final sea trials and are about to be delivered to the Navy.

The two submarines, No. 9527 and No. 9528, have been replaced with the Chinese Navy's submarine-type marine camouflage livery, and the two submarines are docked side by side on the pier in red and color, like a team of sisters about to be married.

The two young naval lieutenants looked at the submarine in front of them with joy on their faces, as if they were looking at their own brides. True, they are about to become the official captains of these two submarines.

A representative of the manufacturer came over with a smile and said to them: "Major Tantai, Major Ram, please come and sign...... He jokingly wiped his eyes and pretended to be sad and said: "Oh, our daughter will be handed over to you in the future......"

"Hahaha, don't worry, uncle. I will take good care of your daughter in the future......" Ram Feizhu echoed with a smile.

Coincidentally, the two captains this time have rare double surnames. Tantai and Ram are both very rare surnames, and it just so happens that they are classmates, so it is natural for them to become friends.

After the two signed, they took a group photo with representatives of the Navy and the manufacturer. Then, according to the usual practice, all the officers and men were brought together and took a few group photos with the submarine as the background.

"Tantai, ram ......" the naval representative was a colonel, and after taking a group photo, he smiled and said to the two captains: "This is our most advanced 'big herring'." You work hard and strive to open a 'big black fish' in the future......" Herring and black fish are the black words of the navy, the former refers to conventional submarines, and the latter refers to nuclear-powered submarines.

"The big black fish is going to be a colonel, if you can go up in eight years, you can burn high incense. Ram Feizhu sighed.

The current People's Liberation Army has long been regularized, and there is no shortage of officers at all; in this kind of peacetime, if it is not for the kind of academic hegemonic genius or military demon, it is not easy to be promoted from major to colonel, and it is usually easier to become a lieutenant colonel. But it's a bit more difficult to get to the colonel, and on average, one of the five majors can be promoted. Ram Feizhu thinks that he is not a scholar genius or a demon, so he doesn't have much confidence.

Taiming also shook his head: "If you don't fight, you can only stay qualified......" If the ram has no bottom in his heart, he is even more bottomless in his heart.

He was in the "Navy Espionage Case", although he was not implicated in the end, but he was also hung out for a few months. By the time the review was completed, the original nuclear submarine in service could not be re-launched, and his position had already been filled. However, he also did a good job in the submarine force, and he happened to be promoted this year, so after discussion, he was appointed as the captain of the new submarine.

Although he himself has no problems, he has no bottom in his heart when he thinks of his father.

"Hahaha, don't worry, it's a world war now, and you don't have to worry about ......not fighting," the colonel smiled and said meaningfully. "Alright, you are all ready to set sail and drive the submarine back to Coconut City (Jakarta) to ......"

Submarines No. 9527 and No. 9528 were assigned to the Nanyang Fleet, and now that they have been handed over, they will return to the home port of the Nanyang Fleet, Coconut City, to register and report for duty.

..................................................................

The two submarines in this batch are the latest conventional submarines of the Chinese Navy -- the Type 914 "Great White Shark-class" all-electric ocean-going attack submarine.

Submarines for civilian and scientific purposes are not counted, and so far, China has produced a total of 18 types of military submarines, namely Type 901 to Type 918. Thereinto:

The three types of 901, 906 and 907 are all foreign trade types, and they are the main export submarines from before World War I to the 30s, especially. At present, the 901 and 906 models have been discontinued, and the 907 models have also been authorized to a few younger brothers to play by themselves, and China itself has not produced them.

The Type 902 "Sea Seal Class", the Type 903 "Seal Class", and the Type 904 "Sea Lion Class" are attack submarines used by the Chinese Navy during World War I and interwar periods, and they have all been retired from active service.

The Type 905 "Manatee" and Type 908 "Walrus" are two ocean-going transport submarines that are still active on the front lines of humanitarian aid and carry out special missions.

The Type 909 "Bottlenose Dolphin-class" submarine is a treaty-type submarine developed by the "Navy Holiday", and is now the most equipped submarine in the Chinese Navy, and after the latest model of the Type 914 "Great White Shark" electric submarine is built one after another, they will also complete their historical mission, retire from active service, or disassemble or dismantle sensitive equipment, and sell it to other countries.

The Type 910 is a ballistic missile technology verification model, and the Type 911 is a nuclear power technology verification model. There are not many of these two, the former has only one, and the latter has only two, and neither of them is officially in the army.

The Project 912 "Moby Dick class" and the Project 916 "Seawolf class" are nuclear-powered attack submarines. The Type 913 "Sperm Whale Class" and the Type 917 "Canglong Class" are nuclear-powered strategic missile submarines.

The Type 915 "Blue Whale class" is a nuclear-powered giant special submarine, which is currently the largest submarine in the world, with a displacement of up to 26,000 tons on the surface, 48,000 tons under the water, and a payload of up to 15,000 tons. It is mainly used to replace the aging "Manatee" and "Walrus classes", and its main task is also for transportation and special purposes, and is usually not used for direct combat.

Then there are the two latest conventional submarines, the Type 914 "Great White Shark" electric ocean-going attack submarine and the Type 918 "Finless Porpoise" small electric offshore attack submarine.

The "Great White Shark" submarine is a large ocean-going attack submarine, its appearance is relatively close to the German Type 216 submarine of the original time and space, with X-type tail rudder, cigar-shaped hull, and "artificial shark skin" laid on the shell, which has the dual role of silencing and reducing drag. It has a total length of 88 meters, a total width of 9.5 meters, and a draft of 8.5 meters on the water. The water displacement is 3,150 tons, the submersible displacement is 4,600 tons, and the maximum diving depth is 700 meters.

The biggest difference between it and its predecessors in appearance is the use of X-shaped tail rudder, this design has higher maneuverability than the traditional cruciform tail rudder submarine, which can make the rudder surface obtain the maximum wing area under the premise of not exceeding the middle contour of the hull, which can not only increase the effective rudder area and improve the movement, but also is not easy to cause damage when sitting at the bottom and berthing, and is more suitable for operation in hydrologically complex sea areas and shallow sea environments than cross rudders.

In addition, the traditional cruciform tail is divided between horizontal and vertical control, so in the event that the rudder surface in one axial direction fails completely, only the control ability of the other axis remains. However, the four rudder faces of the X tail are involved in both horizontal and vertical control, so the tolerance for partial wing failures is high, and the failure of either two rudder faces still retains complete directional control. However, the movement of the X tail is more complex and needs to be controlled by a computer, which is the biggest difficulty of this technology.

At present, this is also the most advanced computer technology that China can afford, and other countries can only play with the cruciform rudder.

Unlike later generations of new submarines equipped with "air-independent power plant" (AIP), the Jaws class is also equipped with a fuel cell power system, but this is only auxiliary power. Its main power source is the 300-ton Silver Dragon battery in the battery compartment, which can provide sufficient power. Even if it has a large number of electrical equipment, etc., the energy of these batteries is enough to make it dive underwater for 220 days at a cruising speed of 8 knots, with a range of more than 40,000 nautical miles.

Of course, people can't stand playing like this, and it's actually impossible to do so. In other words, great white sharks are only limited by the physical fitness and food capacity of the crew when they are in low dives. According to the regulations, its endurance is about 20,000 nautical miles, and the support capacity is 50 days, during which it can dive underwater all the way, which is not much worse than a nuclear submarine.

..............................................................................

The Mako Shark submarine.

The Mako Shark is the submarine No. 9527, and the other No. 9528 is called the Thresher Shark. Originally, the Chinese Navy's submarines only had a ship number without a name, and this convention was not broken until the Type 909 "bottlenose dolphin-class" treaty submarine entered service. This is also because China's submarines are getting bigger and bigger, and submarines of several thousand tons do not have their own names, and it is indeed a bit unusual.

The Mako Shark quietly sailed out of the dock of the shipyard and headed for Coconut City (Jakarta) at an underwater speed of 8 knots.

The level of automation of the Jaws class is quite high, and after the route is set, nothing will happen. Sitting in the captain's seat, he seemed to have nothing to do, and he was thinking about whether to play a game for a while when he heard the voice of the chief of communications.

"Captain, there is a mission......

"Oh......" Yu Taiming hurriedly took a look, only to see a task prompt appear on the screen of the command computer.

"Red Envelope...... Urgent mission ......" Taiming was shocked.
