In the past few days in Guangzhou, Fan Heng seemed to be a little preoccupied.

One of the reasons is naturally that Fan Wuzhi made it, and the second reason is that he came to inspect Tongfeng Company for a few days and felt something.

In recent years, state-owned enterprises have been struggling!

Take Fan Heng's Pingyuan Machinery Factory as an example, it is a military industrial enterprise, relatively speaking, it is better, the military's orders can basically maintain the basic operation of the factory, but it is difficult to develop greatly, after all, since a few years ago, the country's main propaganda tone to the outside world is peaceful coexistence, so this armament issue can not be too relaxed, so as not to teach the truth.

The Plains Mechanical Plant is an enterprise that supplies the Navy with shipborne weapons, simply put, specializing in the production of a torpedo.

A torpedo is a weapon used in the water in naval warfare, and after being fired, it can control the direction and depth of navigation by itself, and when it encounters a ship, it can explode as soon as it touches it. It has the characteristics of fast sailing speed, long range, good concealment, high hit rate, and great destruction, and can be said to be an "underwater missile."

Torpedoes were mainly aimed at warships and submarines, and could also be used to block ports and narrow waterways. Its front part is a thunder head, which is equipped with ZHA medicine and a fuse; The middle part is a thunder body, equipped with navigation and control devices; The rear part is a fishtail, which is equipped with power units such as engines and thrusters, and the power system energy sources are gas and electricity, respectively. According to different needs, torpedoes are divided into three types: large, medium and small. large torpedoes with a diameter of 533 mm or more; Medium-sized torpedoes with a diameter between 400~450 mm; Small torpedoes with a diameter of 324 mm or less. Torpedoes are mainly carried by ships, but if necessary, by airplanes.

At the beginning of World War I, torpedoes were already recognized as the main weapon of ships after artillery. During the First World War, 11.53 million tons of transport ships were torpedoed, accounting for 89% of the total tonnage of sunken transport ships; 162 ships, accounting for 49% of the total number of sunken ships. During the Second World War, the total tonnage of transport ships sunk by torpedoes reached 13.66 million tons, accounting for 68% of the total tonnage of sunken transport ships; The number of ships reached 369, accounting for 38.5% of the total number of sunken ships.

Compared with missiles, the role of traditional torpedoes has great limitations, and it is only suitable for attacking sea surface ships or shore-based fortifications, or for the offensive mode of submarines under the sea, unlike missiles, which can be applied on the surface of the sky and the ground, and its combat radius is much smaller than that of missiles.

Domestic torpedo weapons, due to historical reasons, are basically in the same vein as the torpedoes developed by Soviet Russia, and their technical surname can only stay on the thermodynamic torpedo of the early 20th century, that is, the commonly known steam gas torpedo.

In foreign countries, the development of torpedo technology can already be described as changing with each passing day.

In 1938, Germany was the first to equip submarines with electric torpedoes without tracks, which overcame the shortcomings of thermal torpedoes that were easy to detect due to the formation of tracks due to the discharge of gases during navigation. In 1943, Germany developed a single-plane passive acoustic self-guided torpedo, which could receive the noise of water and ships and automatically guided the torpedo, thus improving the hit rate. At the end of World War II, Germany invented wire-guided torpedoes, and the launching ships were guided by wires connected to the tail of the torpedoes, which were not easy to be interfered with.

In the mid-fifties of the twentieth century, the United States made a two-plane active acoustic self-guided torpedo (also known as an anti-submarine torpedo), which can search in three-dimensional space in the water and attack submarines. In 1960, the United States was the first to develop the "Asrock" rocket-assisted torpedo (also known as an antisubmarine missile), which automatically searched, tracked, and attacked submarines from the rocket's flight to a predetermined point of entry into the water. After the 70s of the 20 th century, the torpedo adopted a microcomputer, improved the function of the self-guidance device, and strengthened the ability to resist jamming and identify targets, and its speed has been increased to 90 to 100 km/h, with a range of 46,000 meters. Especially on attack submarines, torpedoes are the main attack weapon.

In the past, Fan Heng was limited to his status level, and the work he did was only responsible for the final assembly of torpedo weapons, but now that his level has been raised, he has seen more internal information correspondingly, and after learning about the huge gap between domestic and foreign, the shock in his heart is indescribable.

How to survive and develop domestic military enterprises is a big question, and it is not something that can be decided by cadres at the level of Fan Heng, but this does not affect him to think about this issue with his own mind.

The torpedo technology of the Plains Machinery Plant naturally originated from the Soviet Union, and later developed part of it independently, because Sino-Soviet relations have been in a hostile state since the sixties, so the technological progress is very limited, and the gap with the developed countries is also getting wider and wider. Since the beginning of this year, Sino-US relations have gradually warmed up, and after obtaining some technical embargos, China is also developing its own electro-powered torpedoes, and the results are not bad, but compared with the latest torpedoes, they are obviously not at the same level.

At the beginning of this year, the self-defense counterattack war against Vietnam broke out, and a month of continuous strikes made Vietnam a lot of peace, and the battle on the sea also achieved certain results, especially the capture of a complete new Soviet-made torpedo. The military immediately pulled the torpedo back to the Tongfeng Company in Guangzhou for dissection and research, in order to obtain the core technology of the key surname.

The delegation headed by Fan Heng mainly came to contact with the Feng Company and absorb advanced experience, and the military enterprises under the Ministry of Machinery Industry naturally have nothing to dwell on on the issue of secrecy, and the key is to see that the technical force in that area is more abundant, and the results obtained will naturally be more abundant.

Although Fan Wu's illness caused some trouble to Fan Heng, he took the lead in his work, and he brought the most top-notch technical strength in the factory, so he couldn't let his colleagues in Tongfeng Company, who was a brother unit, see the jokes.

Therefore, as soon as Fan Heng entered the state, he didn't care about Fan Wu's illness.
