As reports from various combat departments came in, Li Hai held the microphone in his right hand and stared coldly at the target sea area. At this time, the sun was behind him, the light was very good, the weather was very good, and under the calm sea, there was something hidden.
The unidentified advanced submarine was finally exposed.
Song Jianming, Zhang Lei and others were looking at him, and the entire bridge duty crew was looking at him. As long as the captain gave the order and the combat procedure was started, it would be a real work.
This decision is really hard to make.
This is because the Zhuyuan set up this time is heading towards the sinking target, which is completely different from the last time. If the superiors later think that there are problems with the procedure, the captain will undoubtedly be the first person responsible.
No one was disappointed, the young trainee captain's style was consistent.
Li Hai brought the microphone to his mouth and gave the order clearly and decisively, "Deep bomb attack, prepare torpedoes!"
"Depth bomb attack!"
"Depth bomb attack!"
Two depth charge launchers on the bow deck began to fire a salvo, pouring twelve depth charges into the target sea area in a covering manner.
This is a coverage attack.
The depth of the depth bomb fuze is from 30 meters below the signal source upward, with two fuses set for every 10 meters. The ten depth bombs cover the water level 20 meters above the signal source.
In terms of dispersion, we also focus on the signal source, striving to sink the target in the first attack, or at least force it out of the water.
After the first wave of depth charges was launched, the bridge quickly became quiet, for fear of affecting the sonar crew's monitoring and searching.
"Left full rudder." Li Hai ordered.
"Full left rudder!" Song Jianming subconsciously repeated the command. The helmsman quickly turned the steering wheel to the left, and the No. 53 ship began to turn sharply to the left.
Only then did everyone realize that the captain was engaging in tactical evasion.
The target will not fight back even if it is hit, maybe it is already preparing to launch a torpedo.
Strike first to gain strength and strike later to suffer disaster. Ship No. 53 discovered the unknown advanced submarine. It may not have failed to discover Ship No. 53.
If the commander of the unknown advanced submarine is also a ruthless person, he is very likely to attack the No. 53 ship.
Ten depth bombs were laid, and soon, several large waves exploded in the sea area. Water ripples spread out from the center of the explosion, and then collided with other water ripples, forming a localized wave in this sea area.
The image of a stormy sea.
The No. 53 ship turned sharply for tactical evasion. For modern torpedoes, the ship's tactical evasion is basically impossible to escape. To deal with torpedoes, the use of depth bombs is a more effective method. If the torpedo is regarded as a micro submersible
, then the torpedo is within the attack range of the depth bomb.
A large number of active warships of the People's Navy retain rocket-type depth bomb launchers. One of their functions is to counter torpedoes. When necessary, they can even shoot at land to provide fire support for landing troops. In fact, the People's Navy often uses depth bombs to counter mines!
It is cheap, reliable and has a wide range of uses, just like the 107 mm caliber multiple rocket launcher used by ground forces to this day.
After the second reloading of the deep bomb squad, the purpose is to guard against torpedoes that may be launched by the enemy. The monitoring in the sonar room also focuses on the torpedoes launched by the enemy.
The transition between attack and defense is very smooth. This is due to the high degree of tacit understanding formed by the veteran battle team of the old ship. As the commander, Li Hai does not need to pay attention to every detail to give instructions.
Li Hai's actions were too fast. The unknown advanced submarine discovered the No. 53 ship before its position was exposed. Its surface and underwater target detection capabilities were too powerful. However, the commander of the boat focused on
The reason was very simple and reasonable - it was most advantageous to deal with Wu Hai first, and he deeply felt the huge pressure brought by Wu Hai.
The unknown advanced submarine has already analyzed the situation of the No. 53 ship through sonar characteristics. The relevant information of the ship can be obtained from the intelligence database immediately. Knowing that it is an old 053-class frigate, naturally it will not put the No. 53 ship on the
In eyes.
What was never expected was that the No. 53 ship moved so quickly and sharply. What was terrible was that the first wave of the No. 53 ship's attack hit ten rings - covering the sea area where the unknown advanced submarine was located.
An unknown advanced submarine was in the process of launching torpedoes. The commander of the submarine was also a ruthless person. At this critical moment, he actually waited until the torpedo launch was completed before issuing an emergency dive order to avoid deep bombs.
The depth bombs exploded continuously underwater, and the entire sea surface trembled, as if a small earthquake had occurred.
At the same time, a torpedo launched by an unknown advanced submarine rushed toward the No. 53 ship.
The sonar room has been paying close attention to the movements of the unknown advanced submarine, and it was captured by the sonar crew as soon as it launched a torpedo.
"Torpedo incoming! Bearing 035, distance 3 nautical miles, target speed 37 knots!" The sonar operator's voice was almost the only voice in the bridge.
The torpedo is accelerating, and only 3 nautical miles can pass in the blink of an eye.
Song Jianming's adrenaline is soaring. He was only in elementary school during the August 4th naval battle and has been serving in the Navy ever since. Especially on the No. 53 ship, he has a very rich experience, which is richer than his comrades working on other ships.
However, I have never encountered such a situation as a real torpedo attack!
He subconsciously looked at Li Hai, and was surprised to find that the trainee captain, who was fifteen years younger than him, was very calm and clearly enunciated the battle instructions: "Deep bomb coverage, full starboard rudder, sharp turn, bow facing
The direction of the torpedo attack!"
Deep bomb coverage is active defense, and emergency turning with the bow of the ship toward the direction of the torpedo attack reduces the attack area of the torpedo.
However, maneuvering evasion is difficult to achieve, because modern warships no longer use direct-navigation torpedoes. They are all torpedoes with self-guiding capabilities. Some wire-guided torpedoes can even attack any part of any target according to the operator's instructions.
.
The unknown advanced submarine uses the MK-48 heavy-duty torpedo. The guidance system of this torpedo is very advanced. It is wire-guided plus active and passive acoustic homing. It can be controlled by the shooter or can seek independently.
The sound source of Ship No. 53, which is sailing at high speed, is very obvious. At such a close distance, it is almost impossible for Ship No. 53 to escape.
Therefore, Li Hai put the command of maneuvering evasion last, and first carried out a deep bomb anti-torpedo attack.
Just when Song Jianming was about to remind him that deep-bomb anti-torpedoes alone could not ensure safety, and that the entire ship should quickly prepare for damage control and abandonment, Li Hai issued the second combat order: "Lock on the incoming target, torpedo three
Shoot, launch!"
It turns out that he asked the torpedo department to prepare for attack not against the unknown advanced submarine, but against the MK-48 heavy torpedo that the boat might launch!
Attack torpedoes with torpedoes, genius idea.
The No. 53 ship uses a medium-sized torpedo, which is not as good as the MK-48 in terms of performance, but it is superior in terms of high accuracy and can hit wherever you point it. Moreover, it also uses a guidance method of wire guide plus active and passive acoustic homing. As far as the guidance system is concerned,
, on the same level as the MK-48 torpedo.
Song Jianming knew that Li Hai had already made arrangements, and he breathed a sigh of relief.
"Captain, you are responsible for damage control." Li Hai said solemnly.
Song Jianming said solemnly, "Yes!"
Chang Haizhou is responsible for damage control, but now that he is at the war center, a leader above the department head is needed to direct damage control, and Song Jianming is the only one.
After entering the wartime state, there will be at least two people in each position. When the person on the job is unable to perform his duties, the second person will immediately take over as a substitute, and the command team will be the same.
After Song Jianming was in charge of damage control, once he was attacked, Song Jianming would leave his current post. At that time, it would be his deputy who would provide Li Hai with navigation advice.
The torpedo was launched.
Commander Shui Wu is keeping an eye on the torpedo squad.
The previous deep bomb coverage shooting was personally performed by Gunnery Chief Zhang Lei.
Whether the first deep bomb coverage attack can hit the target is not the most important at this time. The problem before us is how to prevent the enemy's torpedo attack.
3 nautical miles, the MK-48 heavy torpedo only takes 4 minutes to complete.
In these 4 minutes, Li Hai only had one chance to actively defend at most.
He picked up the transmitter and ordered continuously, "The main and secondary batteries fire intensively at the incoming torpedoes. Don't worry about the ammunition. Aim at its sailing direction and hit me hard! The torpedo department is preparing for the second salvo!"
The key lies in the second salvo of torpedoes!
Whether it can be loaded and launched in the shortest time is a severe test for the torpedo team, and now is the critical moment!
The 100 mm caliber main gun quickly switched from automatic aiming to manual aiming. Zhang Huo felt no pressure at this time because his attention was all on the incoming torpedoes. He quickly directed the soldiers to operate the main gun and aim at the torpedoes.
The route of attack.
Based on the target navigation parameters provided by the sonar department, the shooting point is quickly calculated, which is no different from shooting at a moving target on the water, except this time it is shot underwater.
Whether it can hit it, or whether it can detonate the torpedo, only God knows.
It was originally loaded with high-explosive bombs, but Zhang Huo did not make any mistakes because of nervousness. He carefully set the fuze parameters of each shell in an effort to cover more water layers.
The secondary battery that fires before the main battery is the secondary battery. The No. 53 ship uses four secondary batteries. In the middle between the main gun and the ship building is a Haihongqi-7 eight-unit short-range air defense missile launcher. On the left and right of the launcher.
There is a double-barreled 37mm caliber secondary gun on each side, and a double-barreled 37mm caliber secondary gun is also arranged on both sides of the hangar.
In terms of artillery firepower, the No. 53 ship is very powerful, which is one of the reasons why the ship is frequently assigned the mission of maritime security patrols, anti-piracy and maritime condolences.
Li Hai asked the helmsman to turn 45 degrees to the left. This was to establish a firing range for the main and secondary batteries. Due to the pitch angle, as the torpedo approached, the main and secondary batteries would soon be unable to hit its navigation route.
Moreover, after turning 45 degrees to the left, the secondary guns on the right side of the hangar had a firing range, and a total of three secondary guns began to fire densely towards the torpedo's route.
After the main gun quickly joined the firing, almost all the artillery on the ship started firing.
The torpedo department did not disappoint Li Hai. The second wave of firing started in time, and the loading speed of the torpedo unit broke the previous record!
Using naval gun fire to shoot incoming torpedoes is not a helpless move, but Li Hai is certain that at such a close distance, the depth of the unknown advanced submarine's torpedo calibration will never exceed ten meters, and the depth of the torpedo will never exceed ten meters.
, the main and secondary guns on the ship can pose a threat to targets in this water layer.
Precisely because of the distance, the depth of the attack route calibrated by the unknown advanced submarine for the torpedo is only five meters, which is very conducive to the direct-fire shooting of weapons on the No. 53 ship!
