In January 305, the Samanid civil war was raging, and the Fangtian rebellion spread to the areas of the Tang Dynasty that surrounded the Caspian Sea and had a large number of Fangtian sects.

In addition, the independence movements in the Americas have intensified and tended to develop in the direction of rebellion.

At the request of the Prime Minister, the Imperial Admiralty decided to send a battlefleet to the Caribbean Region to strengthen the North Atlantic Fleet, while the South American Task Force, consisting of the Ninth Fleet, set sail for the Falklands to strengthen the South American Fleet.

It's like a deterrent.

Of course, no one knows exactly what the upper echelons of the empire mean by this.

In Saman, with the support of the Tang Empire, the Samanid government army gradually stabilized its position. By the autumn of the Republic 304, an offensive began on Dehran from both sides. As a result of the "arms embargo", the rebels have no supply of weapons, which basically indicates that the civil war is a foregone conclusion.

The submarine cadets at the Imperial Naval Academy in Jiaozhou have one year more than their counterparts in other majors, and then they have to spend a year on an offshore training craft before they are officially assigned to the submarine force.

Li Haiming, the second eldest of Li Changzhou's family, finally became a member of the Imperial Navy's submarine force in early 305 like his father after five years of study at the Naval Academy and a year as a midshipman officer.

It was his boyish dream.

Of course, the enthusiasm of his youth has almost been exhausted by the boring life of the submarine force, and after less than two months of internship on the boat, Li Haiming understood that the main reason why his father had strongly opposed him to enter the submarine major was not because he was afraid that they would encounter danger, but - this is indeed not a ghost place for people to stay.

The Jiaozhou Naval Base is located at the southern end of Jiaozhou Bay.

The natural conditions are outstanding, and the anchorage in the harbor is guarded by forts and fortresses on all sides. The harbor is home to hundreds of warships, large and small, of the Imperial Navy's surface fleet, and the Imperial Navy's submarine force headquarters is also here.

During the last war, the Empire's merchant ships suffered a lot of losses at sea due to submarine attacks. After the war, the development of submarine forces in the Imperial Navy was more important. From 295 years, the Imperial Navy again began the development and construction of new submarines.

With the addition of more and more technical personnel and officers of the submarine force, the submarine technology of the Imperial Navy has always been at the advanced level in the world.

However, the size of the Imperial submarine force after the reorganization in 295 has not been greatly expanded, and the number has remained at about 230 boats, and the old submarines that have been retained have all been decommissioned before 302 years ago and transferred to the Naval Academy for training.

The development of submarine technology in European countries after the war was greatly influenced by the submarine technology of the Kingdom of West Francia, but each country developed its own relatively unique theory according to its own situation. Among them, the submarine and anti-submarine technology of the West Frankish Kingdom has developed the best.

Due to the vast sea territory of the Tang Empire, submarine forces were required to cross the ocean to conduct long-distance maritime operations, and the submarines designed and built by the imperial navy had relatively large displacement and long endurance, especially the surface speed of submarines was the highest among the navies of various countries. However, due to their large size, the submarines built by the Datang Navy were slightly inferior in terms of maximum depth and concealment compared to the West Frankish Kingdom.

Due to the limitation of the area of activity and the depth of water in the Mediterranean Sea, the Byzantine Imperial Navy initially developed several submarines after the war were medium-sized submarines with a surface displacement of about 500 tons, and it was not until recent years that ocean-going submarines with a displacement of more than 700 tons began to be built, and the number of equipment is increasing year by year.

A few days after reporting to the submarine headquarters, Li Haiming was taken to the submarine dock by a blue Geely Seahorse convertible car marked with the logo of the submarine force, which was hundreds of meters long in a row of gray reinforced concrete buildings. In general, submarines are rarely parked in open docks, and they enter the garage when they are in port.

Inside the garage, a submarine is moored on both sides of a concrete pier more than 100 meters long, some rusty and mottled, others shiny painted, apparently fresh into service.

On the side of the main pier, there are piles of all kinds of parts, some new and some replaced. Several marine diesel engines were dismantled to pieces, and the fuselage covered in grease emitted a foul smell of oil. There were blue-blue sparks on several submarines, and maintenance crews were welding something they were cutting or welding to the boat.

Some were busy with their work, while most of the crew who stayed behind were bore, wandering around, or gathering at a table by the wall to brag, play cards, or play chess.

Several captains were gathering to chat about the recent annexation of the three Baltic states of Estonia, Latvia and Lithuania by the Kingdom of West Francia.

The naval officers of the Tang Dynasty did not feel anything about what happened to these Baltic states, but the army in the Urals, especially on the western border, reacted much stronger. In the eyes of most of the young professional officers of the Imperial Navy, the West Franks were not the focus of their consideration, and the Tang Empire was invincible at sea.

Defeating the Datang Navy is the dream of the naval officers and sailors of other European countries.

Just like the famous Imperial Navy battle song called "On the Expedition to the Franks".

Major Huo Yanhao, the captain of the BF51 boat, is very prestigious among these captains. He was transferred from the BF06 boat, graduated from the Naval Academy five years before Li Haiming, and is a veteran captain. Under his command, the BF06 submarine won three excellent projects at the same time: engineering, gunnery and torpedo in the Navy's martial arts exercises. Moreover, under his command, the movements of the BF6 boat are simply like a finger, and the beautiful dock technique is breathtaking, and it has become a classic lesson plan for the submarine force.

Major Huo Yanhao is very famous and highly regarded in the submarine force, and there is no doubt that he will be a rising figure in the future.

The sergeant who sent Li Haiming over stepped on the brakes, and the car stopped in front of the officers.

"Sir, this is Lieutenant Li Haiming, the officer who has just been assigned to you." The sergeant said to Major Huo Yanhao. Li Haiming had no choice but to follow the sergeant, saluted his new superior, and then handed over his military ID card and the letter of appointment issued by the submarine command.

"Oh, Li Haiming, good name, just graduated this year?" After Huo Yanhao read Li Haiming's certificate and letter of appointment, he looked him up and down, and asked lukewarmly.

"It's been a year since I graduated, and I used to intern on DFT11, sir!"

"Uh-oh, you should know what a T in the middle of this boat means, Lieutenant." Huo Yanhao showed a sly smile on his face, "There is a lot of equipment missing on it. Launing, come here! The major turned his head and shouted at a sergeant major standing next to his new submarine.
