After more than a month, Yang Wenbin slowly became familiar with the time and rules of the navy's work and rest, and personally integrated into the navy's training. Pen & Fun & Pavilion www.biquge.info

In particular, there is also a certain understanding of the establishment of the Navy and the performance of the ships.

He learned that the Navy has three major fleets, namely the North Sea Fleet, the East China Sea Fleet, and the South China Sea Fleet.

Among them, the fleet that Yang Wenbin is acting for belongs to the North Sea Fleet, which is at the level of a deputy military region.

The headquarters is located in Jiaozhou Bay, Daoqing City, Dongshan Province.

It consists of the North Sea Fleet Command and the Political Department of the North Sea Fleet.

The main combat units include: the second destroyer detachment, the fourth destroyer detachment, the first submarine detachment, the third submarine detachment, the first aviation division of the North Sea Fleet, and the first nuclear submarine detachment.

It has jurisdiction over Bincheng support base and island green support base.

Yang Wenbin's fourth destroyer detachment is stationed in Bincheng Shunlu East Port, with four destroyers and four frigates.

Including 2 Type 051DT destroyers: 201 Dalian and 202 Kaifeng.

2 Type 051D destroyers: 210 Guilin and 211 Nanchang.

4 Type 053H3 frigates: 5O1 Luoyang Ship, 502 Mianyang Ship, 503 Huludao Ship, and 504 Yichang Ship.

Each missile destroyer is generally 132 meters long, 12.8 meters wide, and has a draft of 4.6 meters. Displacement, 3200 tons in standard case, 3750 tons at full load. The speed is 32 knots. The cruising range is 2970 nautical miles / 18 knots.

Judging by the weapons equipped on the ship, the firepower is still strong.

The stern of an ordinary destroyer is equipped with four double-mounted YJ-8 missile launchers; 1 8-link "Sea Sidewinder" anti-aircraft missile launcher; 2 double-barreled 130-mm guns; 3 double-barreled 37-mm automatic anti-aircraft rapid-fire guns; 3 batteries with 2 324-mm torpedo tubes; 12-tube anti-submarine rocket fixed launcher 2 seats.

There are also destroyers, the main guns and anti-aircraft guns on the rear deck have been removed, helicopter platforms and hangars have been added, and two Z-9 anti-submarine helicopters have been installed. This is the only one of the brigade-class missile destroyers capable of carrying helicopters.

As a matter of fact, the training of the naval forces, like the training of the army units, has a phased training plan, a monthly training plan, and a weekly training plan.

According to the rules and regulations, different arrangements will be made according to their actual situation.

Generally speaking, it takes 100 days for full-training ships to go to sea each year, and 60 days for retraining ships, and other ground service units generally do support training.

The training of naval units is divided into shore and port training and sea training.

Shore port training is to do simulation operations in the training room, carry out theoretical education and learning, maintain machinery and equipment, etc.

There are subjects for sea training, such as day and night sailing or anchor training.

In addition, training in general subjects such as cohort training is also essential.

As for the training of destroyer units, different training contents and methods are adopted according to different specialties.

Therefore, since there are so many specialties on the ship, the most basic training is the training of each specialty.

For example, ships, professional training in piloting. With so much equipment and parts on a ship, how do you drive it? The most basic profession on a ship, of course, is driving.

Only by studying theory, practical operation, and division of labor and coordination can we get the huge destroyer into action, and this is the task to be completed by the piloting profession.

There is also training in the handling of weapons. For example, the operation training of anti-aircraft missiles, the operation of naval guns, the operation of anti-aircraft missiles, the professional training of anti-aircraft artillery, the professional training of torpedoes, and the training of anti-submarine operations.

These trainings are continuous, requiring both certain theoretical knowledge and a certain practical operation foundation, and must be carried out by combining theory and practice.

The third is communication training. When a ship sails on the sea, how to communicate between various battle positions, how to communicate between ships, and how to communicate between ships and bases is also a very professional training process.

So after the first few months of shore and port training, the fleet was going to go to sea for training.

Cadres of the Navy's political organs, like cadres of the Army's political organs, must also receive training in the Navy's relevant specialties.

As a big challenge, Yang Wenbin also boarded the ship and participated in military training.

Of course, due to the limitations of his major, he mainly participated in the training of the communication major. This is a professional skill that a naval officer must master.

As an officer, if you can't even operate communications, how can you command a battle? How to contact the upper and lower contacts?

There is also the training of reading and using pictures.

As an army, Yang Wenbin's map recognition and use skills are still very strong, but now at sea, as a navy, he has to use nautical charts.

Yang Wenbin felt that the nautical charts were much more difficult to learn than the army's military topographic maps.

Because in the vast sea, there are not many prominent terrain features. There are very few conditions for judging the terrain and the basis, which requires solid basic skills.

Fortunately, the instructor invited by the detachment's officer training was named Li Zhuozhuo, and his explanation was still very serious and detailed.

"Nautical charts are maps that take the sea as the main object of description, and focus on the topographical elements and navigational aids related to navigation, maritime warfare and training. It is an important topographic data for sea navigation, operations, organization of landing and anti-landing operations, as well as harbor construction and marine development.

What is the ocean? The vast continuous body of water on the surface of the earth, known as the ocean. Its center and main body, called the ocean, is vast and far from the continent, with a depth of more than two thousand to three thousand meters. Its marginal part, called the sea, borders the continent and is mostly within 2,000 to 3,000 meters deep. There are usually islands, archipelagos, peninsulas or continents between oceans and seas, separated to varying degrees. The area of water that juts out into the land between the sea and the ocean and gradually decreases in width and depth is called a bay. A narrow waterway that connects the two bodies of water, the sea or the ocean, is called a strait. ”

Li Zhuozhuo emphasized: "To learn nautical charts, we must first understand the ocean tides.

The phenomenon of the rise and fall of the sea surface, during the day, is called tide, and at night, it is called tidal, which is collectively known as ocean tides. When the sea level rises to the highest point, it is called high tide, and when it descends to the lowest position, it is called low tide. The process of the sea rising from low tide to high tide is called high tide, and the corresponding time interval is called high tide time. The process of descending from high tide to low tide is called low tide, and the corresponding time interval is called low tide.

Because the moon and the sun have a gravitational attraction to the earth, especially the moon, according to the nearest earth, there are gravitational forces of different magnitudes and directions to points at different positions on the earth's surface, and this gravitational difference makes the seawater flow regularly and form tides.

On the synodic day of the lunar calendar every year, the sun, the earth, and the moon are located in the same cross-sectional direction, and the sun's tidal force is roughly the same as the direction of the moon's tidal force at this time, and the resulting tidal force is the largest, and the sea level rises the highest and falls the most, so there is a high tide, and people often say, 'the first and fifteenth high tides', 'the eighth and twenty-third days of the first month, see beaches everywhere', this is the reason. ”

"Nautical charts, according to the content and purpose of the representation, are divided into ordinary nautical charts and special nautical charts.

Common nautical charts include harbor charts, coastal charts, nautical charts, and general sea area maps.

Harbour charts, which focus on harbors, anchorages, and waterways, are called harbour charts. The map shows in detail the nature of the coast and the topography of the seabed, the water depth, the bottom quality, the navigation aids, the obstacles, the anchorage, the harbor facilities, etc. It is mainly used for ships entering and leaving the port, anchoring, laying mines, organizing landing and anti-landing operations, and harbor construction.

Coastal map, a detailed coastal map that depicts the coast in detail, with detailed representations of coastal steps, reefs, rocky beaches, and coastal navigation signs. It can also be used for guarding islands and fortresses, laying and sweeping mine obstacles, studying coastal topography and coastal artillery positions, as well as organizing and landing anti-landing operations and training.

Nautical charts are mainly charts that depict the scope of the sea area and a certain waterway, focusing on the main island and shore targets, navigation equipment, sea depth and seabed landform, etc., mainly for ships to sail in the near sea, in the middle sea and in the open sea.

Special nautical charts include reference charts, special nautical charts, etc. ......"

The teacher of map reading and using the map spoke very carefully, and everyone listened carefully, and Yang Wenbin felt that he had benefited a lot.
