But at this moment, there was only a loud "boom", and the huge hull of the Count Bismarck suddenly trembled, and several officers in the command room were in a hurry to take precautions and fell to the ground one after another.

"Shot!" Heinrich's mind suddenly flashed such a thought, but at this time he was still calm, and immediately said loudly: "Report the bomb part, the loss ......"

Before Heinrich finished speaking, he heard two more "booms", and the Count Bismarck was hit by two more shells, one of which landed on the foredeck of the Count Bismarck, and the two pieces of glass in the command room were shattered by the steam wave, and when I looked out of the porthole, I saw that the guns of the other ships were all firing, and the Brandenburg, the lead ship of the other group of German ships, was also hit by two bullets, and several water columns were raised on the sea surface left and right in front of the two ships.

Heinrich was shocked at this time, if he said that he only received one shot, it can be said that it was accidental, but the Count Bismarck was hit three times in a row, and the Brandenburg on the other side was also hit by two shots, which cannot be explained by luck, it can only be said that the other side is aiming and shooting, not indiscriminately. And the other side was able to maintain such an accurate hit rate at a distance of 10 kilometers, in Heinrich's understanding, even the British probably did not have such an accurate level of shelling, so how did this group of overseas Chinese do it?

But now is not the time to think about these things, after all, the war is critical, Heinrich immediately ordered, ordered the fleet to turn immediately, to the side of the enemy to fire back, although at this distance, the German fleet's artillery can not carry out accurate fire at all, but now there is no other way, originally in Heinrich's plan, it should be closer to six or seven thousand meters before the turn, but the other side can fire ten kilometers away, and there is a fairly high hit rate, so you can only turn in advance, fire back at the opponent from a long distance, it is better than only being beaten and not fighting back。

And just when Heinrich made this decision, the Count Bismarck was hit by three more shots, but fortunately, although the Count Bismarck was only an armored cruiser, the armor was not much thinner than that of ordinary battleships, and it was made of the latest surface carburizing hardened steel plate produced by the Knoob Company, and the part of the cannon was not fatal, so the damage was not great.

After the Count Bismarck turned, the four guns in the bow and stern of the ship also opened fire together, bombarding the other side, and behind the Count Bismarck, the Queen Victoria Louise also began to turn.

After all, the strength of the German fleet is much stronger than that of the Japanese fleet in the last naval battle, and the three Brandenburg-class battleships are equipped with six 280 mm guns, so they must be pulled to more than 10 kilometers apart in order to basically ensure the safety of the crossing fleet, and even if it will be hit, it will give the close defense guns enough reaction time to intercept the shells. Although the hit rate of crossing the fleet dropped to about fifty or sixty percent at a distance of 10 kilometers, it was still a god-like hit rate in this era.

As a result, in just over a minute, the Count Bismarck and the Brandenburg, each of the two German ships, were hit by more than 10 shots, but fortunately, the armor of these two warships was thick, and the shells suffered were mostly 100 mm shells and 76 mm shells, so they could still stand up.

And as the German ships turned one after another, the other ships behind the two ships were also revealed, and the two fleets gradually opened up the distance, the main fleet spread out horizontally, and the crossing fleet launched a confrontation, while the guerrilla fleet went around to the left, trying to attack from the flank of the crossing fleet.

The sea was filled with gunsmoke, the sound of artillery roared, and the water column rose in all directions, and the battle was very fierce for a while.

However, as the battle unfolded, German ships continued to be hit, and at the other end of the battlefield, although near the passing fleet, the water column was undulating, but not a single ship was shot.

In the command room of the Kunming ship, Shang Jinfeng, the commander of the crossing fleet, while watching the fierce battle on the sea in front of him, ordered the water guidance department: "Prepare to launch torpedoes, targeting Bismarck and Brandenburg." ”

In this battle, the use of torpedoes against the German fleet, instead of missiles, was also decided before the war, because in the previous battles, the effect of hitting the warships of this era with missiles had already been tried, so in this battle, the power of torpedoes was to be tested.

The five combat warships that crossed the fleet were equipped with two triple 324mm7424 torpedo launchers, which could launch Yu-7 light torpedoes, and the carrier-based helicopters of the other five combat warships could also carry Yu-7 light torpedoes for airdrop launches. On the Xiangyang and Huaihua ships, each has 12 rounds of Yu-7 light torpedoes, and the Yueyang and Sanya warships are each equipped with 18 rounds of Yu-7 light torpedoes, while the Kunming ship has the largest displacement and is equipped with the most Yu-7 light torpedoes, with a total of 24 rounds, and the five warships combined, a total of 84 Yu-7 light torpedoes, which is another sea weapon for the crossing fleet in addition to missiles.

The origin of the Yu-7 light torpedo is somewhat legendary. In October 1978, a Chinese fishing boat caught an unexploded American MK-46I torpedo in the South China Sea, which was estimated to have been lost during a U.S. military exercise, so the torpedo was sent by the Navy to the 705 Institute for research and testing, codenamed Project 109.

In 1982, the Navy decided to develop the Yu-7 torpedo on the basis of the MK-46I torpedo, and the 705 Institute developed and designed the torpedo shallow water control system, because it was a period of good relations between China and the United States, so in 1985, the United States sold four MK46II torpedoes to China at a price of 8 million US dollars, and one set of intermediate maintenance stations that can complete most of the maintenance work of the MK46II torpedo, as well as a number of technical data. After obtaining this batch of information, the development of the Yu-7 light torpedo proceeded very smoothly, and it was finalized in 1994 and equipped with the troops.

Since the base model of the Fish-7 torpedo was only the MK46II torpedo at the level of the late 70s in the United States, the basic version of the Fish-7 torpedo was completed at the same time, and its improved version was immediately developed. At the end of the 90s, the fully improved Yu-7B torpedo was successfully developed and completely re-equipped, while the Yu-7C torpedo was the latest improvement of the new generation of anti-submarine torpedo technology and developed a helicopter-borne version. The current Yu-7 torpedoes are actually Yu-7 B/C torpedoes, and they are generally equipped with surface ships of the Chinese Navy, as well as various types of carrier-based helicopters.

The basic parameters of the improved Yu-7 torpedo are: a total length of 2.86 m, a weight of 230 kg, a maximum speed of 45, a maximum range of 14 km, and a high-explosive warhead of 45 kg. The search attack depth is 6~400m, and the active/passive sonar guidance is used, and the probability of capturing the target under typical conditions is 90%.

The development of the Yu-7 torpedo is of great significance to the Chinese Navy, the most important of which is the mastery of Otto's thermodynamic technology and advanced active and passive joint sonar guidance mode, which has promoted the improvement of a series of torpedo technologies in China, and shortened the gap between the Chinese Navy's anti-submarine torpedo technology and the United States from scratch to less than 20 years. The development of the Yu-6 heavy torpedo and the more advanced Yu-8 torpedo has played a great role in promoting it, thus laying the foundation for a new era of independent development of China's torpedo industry.

Although the Yu-7 torpedo belongs to the anti-submarine torpedo in the weapon sequence of the Chinese Navy, it is mainly equipped with surface ships and various types of carrier-based helicopters, and at the beginning of the 21st century, it was also equipped with China's early conventional submarines, but with the production of the Yu-6 heavy torpedo, China's new generation of 039 conventional submarines have been reequipped with the Yu-6 heavy torpedo.

However, the Yu-7 torpedo can also be used to attack surface ships, and in this era, torpedo technology has just begun to develop, there is not enough anti-torpedo technology at all, and the Yu-7 torpedo is still equivalent to the technology of the Zenith in this era.

Now the German fleet was lined up in two columns, which became a standard target for the crossing fleet.

The Kunming, Yueyang, and Sanya ships are all equipped with Type 07 medium-frequency bow active/passive sonar below the bow waterline, and at this time, the crew of the torpedo group of the Water Guidance Department has collected all the sonar data of the German fleet, so after Shang Jinfeng gave the order, the sonar data of the Count Bismarck and the Brandenburg were immediately included in the two Yu-7 torpedoes.

Kong Yufang, the female soldier of the leader of the torpedo group of the Water Guidance Department, said: "Report to the captain, the torpedo is ready and can be launched." ”

Shang Jinfeng immediately said, "Launch." ”

Kong Yufang immediately pressed the button of the torpedo launch. In the left rear of the Kunming, two Yu-7 torpedoes were fired from the Type 7424 torpedo launcher. Falling into the sea, it sank quickly and disappeared.

This is the difference between modern smart torpedoes and torpedoes of this era. In this era, the range of torpedoes is extremely close, and they can only be launched within a kilometer, and the torpedo only sails from three or five meters below the sea surface, almost walking close to the sea surface, and a water trail can be seen very clearly from the sea.

After falling into the sea, modern intelligent torpedoes will quickly sink to the sea invisible to the naked eye, and only after approaching the target will they begin to attack the target, so it is impossible to find it with the naked eye. Moreover, modern intelligent torpedoes are either controlled by wire guidance, or guided by active/passive sonar, and can automatically track the predetermined target according to the sonar data input before launch, and they can't run away if they want to, unless there are quite advanced means of jamming, otherwise it is impossible to evade modern intelligent torpedoes.

The Yu-7 torpedo is guided by active/passive sonar, a distance of more than ten kilometers, for a torpedo with a speed of 45 knots, that is, a matter of six or seven minutes, although the torpedo fell into the water, but on the display screen, it still shows the trajectory line of the torpedo and the target, and the data on the side is also constantly showing the distance between the two sides and the remaining time. Shorten it by one minute, and Kong Yufang will report it once.

While waiting, the Yueyang and Sanya ships also fired a torpedo each, targeting the battleship Wools and the ironclad ship Wolfenberg respectively. And the guns of the ships turned to attack several protective cruisers.
