Serial modification of the Type 037 hunting submarine

<>< Type 039 conventionally powered submarine.

Type 039 conventionally powered submarine (known in the West: Song class) is a second-generation conventionally powered submarine designed and built by China. In the process of development, the Type 039 submarine fully absorbed the new concept of conventional submarines in western developed countries, and adopted a large number of new types of forward power, automation equipment, sonar and advanced equipment.

Its combat capability is expected to be on par with the Russian-made "Kilo" class, surpassing the German 209 submarine at the level of the 80s of the twentieth century. The first vessel was completed in 2005 and joined the service of the Chinese Navy.

R&D history: The development time of the Type 039 submarine project began in the mid-to-late 80s of the twentieth century, when China's conventionally powered submarines were mainly the 6633 criminal (referred to as Type 033) after localization and the first generation of conventionally powered submarines Type 035 developed on the basis of Type 033 and independently designed and built.

The technical roots of these two types of submarines are from the former Soviet Union Type 633 R-class, the design age is early, the design ideas are outdated, and the main performance is quite different from the conventionally powered submarines in service in the West in the 80s. In order to meet the operational requirements of the Navy in the new period and to narrow the technical distance between China and the developed countries in the West, China has formally decided to develop a new generation of conventional-powered port boats, and in the mid-to-late 80s, it officially began the development program of the 039 project.

Equipment: The first submarine of this type was completed in 2005. At present, he has joined the Chinese Navy.

R&D history. The development of the Type 039 submarine project began in the mid-to-late 80s of the twentieth century, when China's conventionally powered submarines were mainly the localized Type 6633 (referred to as Type 033) and the first generation of conventionally powered submarines Type 035 developed on the basis of Type 033 and independently designed and built. The technical roots of these two types of submarines are from the former Soviet Union Type 633 R-class, the design is early, the design ideas are outdated, and the main performance is far from the conventionally powered submersible boats in service in the West in the 80s.

In order to meet the operational requirements of the Navy in the new era and narrow the technological gap with the advanced conventional submarines of the developed countries in the West, China officially decided to develop a new generation of conventionally powered submarines, and officially started the development program of the 039 project in the mid-to-late 80s of the world.

The equipment is in good condition.

The first submarine of this type was completed in 2005. At present, he has joined the Chinese Navy.

On May 17, 1971, two 037 small pumpkin hunting submarines of the Chinese Navy's Yulin base in Hainan went to Guangzhou for maintenance. Soon, the tracked submarine had to surface, and it was an American ballistic missile nuclear submarine. China's two submarine hunters followed closely on the left and the right.

The US nuclear submarine urgently called for help at the Subic Bay base in the Philippines, and the US aircraft carrier Midway, which is stationed in Subic Bay, dispatched F-4 fighter jets to deter at an ultra-low altitude in order to attack two Chinese hunting submarines. After the attack order was sent to the Pacific Fleet to no avail, the request was sent to the US Department of Defense and then conveyed to Nixon.

Nixon said that the war against Vietnam was in full swing and China could not be involved. In addition, the United States secretly planned to visit China, so the US military asked for instructions on three attacks, but Nixon vetoed them three times. Subsequently, the U.S. nuclear submarine was escorted by China's armed submarine hunters to China's waters.

From January 15 to 18, 1974, the South Vietnamese Navy successively dispatched the destroyers "Li Changjie", "Tran Thanh Nhuh" and "Tran Binh Chong" and the escort ship "Nu Tao" with a displacement of about 800 tons to invade the sea area of Ganquan Island in the Yongle Islands of Xisha in China. From the 17th to the 27th, two Type 037 boats (port number), together with two Type 6604 hunting submarines (board number) and two minesweepers (board number), carried out a self-defense counterattack against the invading South Vietnamese Navy, which was the first time that the Chinese navy ** boat fought with a foreign navy (called the "Xisha Naval Battle"). The 6 boats of the Chinese Navy are divided into 3 formations, and 2 of the hunting submarines are each equipped with 2 Type 66 twin 57 naval guns.

During the battle, the Type 6604 boat and minesweeper fought fiercely with 4 enemy ships for 1 hour, and 4 South Vietnamese Navy ships were injured. The Type 037 submarine hunting two-boat formation as reinforcements used four Type 66 twin 57 guns to fire three salvos at the wounded South Vietnamese "Angry Waves", causing it to sink immediately and sink 2 hours later, and the other three South Vietnamese destroyers were injured and fled, killing and wounding more than 100 South Vietnamese troops. The Chinese side was seriously injured in one minesweeper, and another minesweeper and a submarine hunter were slightly injured, but they successfully controlled the Xisha sea area, and ensured that the cooperative landing force recovered the three islands of Ganquan, Jinyin, and Coral occupied by South Vietnam, and captured 49 enemy South Vietnamese personnel.

During the battle, the twin 57mm guns of the Type 037 hunting submarine were put into play.

The length of the boat, the width of the meter, the draft of the depth of the meter, the water speed of 20 knots, the underwater speed of 25 knots, the depth of the dive is 400 meters, the loading can be used continuously for 9 years at a time, and the service life is 30 years. The crew of the ship is 133 people, including 16 officers.

The ship-borne "Trident" missiles, each of which contains 7 or 8 sub-guided missiles, have a range of 7,400 kilometers and can attack targets in depth on the enemy's internal and land bases. The boat was also equipped with four 533-mm torpedo tubes and wire-guided torpedoes.

The Type 037 hunting submarine is a small surface combat boat equipped by the Chinese Navy with anti-submarine ** as the main equipment. It is mainly used to search for and attack submarines in the near sea, as well as to perform tasks such as patrolling, escorting and mine-laying. The Type 037 hunting submarine has a displacement of 392 tons when fully loaded, and is mainly equipped with naval guns, rocket-type depth charge launchers, large depth charge launchers, throwing racks and mines.

The USS Ohio submarine is a fourth-generation ballistic missile nuclear submarine designed and manufactured by the United States. Also known as the "Trident" submarine. Construction began in 1976, was launched in 1979, and was put into service in 1981.
