The power of the 381 mm guns was quite terrifying, and the two Hsiungfeng-class battleships were quickly smashed to pieces. Pen % fun % Pavilion www.biquge.info

After the main gun firing is over, pause for a while.

Naval investigators boarded two target ships to conduct on-site inspections of various parts of the ship's equipment and took photographs for future reference and study.

Through a series of inspections of the location of the wounds on the hull, the naval personnel had a rough judgment on the protection ability of the Hsiungfeng-class battleship and the main gun attack capability of the Thor-class super-dreadnought-class battleship.

The Hsiungfeng-class is an old ship of the Chinese Empire more than ten years ago, and the armor protection performance is far inferior to the armor protection of the current Thor-class battleships.

At the same time, the destructive power of the main guns of the Thor class battleships was judged by the damage on the Hsiungfeng-class battleships.

The main gun fire did not directly sink the target ships of the two Hsiungfeng-class battleships, on the one hand, because there was no ammunition and fuel on the target ships, and the boilers were also flamed, so it was not easy to produce serial explosions and martyrdoms. On the other hand, because it is very extravagant to use a retired battleship as a target ship to sink it, and there are not many opportunities, the military will not allow it to be sunk all at once, but will give full play to the value of the two target ships and let the officers and men of the navy take turns firing live ammunition.

After the main gun is fired, the rapid-fire gun is fired live.

Compared to the devastating main gun firepower, the rapid-fire gun caliber is much smaller, but the rate of fire is very fast, so it is also very valuable to watch.

Li Weiguo had nothing to do, so he kept watching the live-fire training.

Among the accompanying ministers, many were taken aback by the previous battleship's main gun fire, and they were all kinds of embarrassed. It was the first time they saw this kind of shocking scene, and they were used to being pampered on weekdays, and Li Weiguo didn't blame them for being soft.

After the rapid-fire guns were fired, naval observers boarded the target ship again to inspect the damage.

This time, the focus is on the killing and wounding of personnel. The location of those dummies can be determined based on the single piece on their body to determine the severity of the damage.

When the Hsiungfeng-class battleship was originally designed, the personnel protection was optimized, and even if it was attacked by the super dreadnought, one-fifth of the personnel were still preserved, which shows that the Imperial Chinese Navy has done a very good job in the protection of this class of battleships, and after continuous improvement, the most powerful Thor class battleship of the Imperial Chinese Navy, as well as the Fury-class battleship under construction, has a higher level of protection.

After some inspection, the overall effect was good, and it was unanimously approved by the observers of the Navy.

After the main and secondary guns are fired, the last thing is the fish and radium attack.

The main ships of the Imperial Chinese Navy have long since canceled the Fish Radium launch system, which was proposed and enforced by Li Weiguo alone.

Several naval battles in history have proved that the probability of a battleship launching a fish ray hitting an enemy ship is too low, especially in the era of dreadnought and super dreadnought, the speed of the battleship is too fast, and the fish ray attack becomes a chicken rib. On the other hand, the battleship installed the Fish Radium launch system, because the protection of the Fish Radium longitudinal wall was weak, once it was hit, if the Fish Ray was detonated, the result would be catastrophic, so the Imperial Chinese Navy canceled the Fish Ray Launch System of the capital ship and only retained it on the cruiser and destroyer.

As several cruisers and destroyers fired seven Fish Radium at the target ship one after another, the two Hsiungfeng-class battleships exploded one after another, the waterline belt armor was torn, and the sea water poured into it violently, sinking at a speed that could be seen.

After the sinking of the two target ships, the live-fire exercise ended.

Li Weiguo gave a lecture to the officers and men of the whole fleet through the ship's radio loudspeaker, congratulated them on their successful completion of the live-fire exercise, and praised their excellent artillery fighting skills.

Two of the artillery commanders, who were hit on the spot, as well as his comrades-in-arms in the same artillery room, were personally rewarded by Li Weiguo, awarded medals, and given generous bonuses as encouragement.

You must know that in naval warfare, as the navies of various countries have entered the era of dreadnought and the era of super-dreadnought, the range of the main guns of their warships has been expanded from the original 10 kilometers to more than 20 kilometers, and even more than 30 kilometers of ultra-long distance.

The farther the distance, the lower the hit rate of the main gun, and it is necessary to rely on constant adjustment to shoot Zhu Yuan, generally at a distance of 20 kilometers, the average hit rate of the naval guns of the Imperial Chinese Navy is about 20%, that is, five shells hit one shot.

The popular general, after four adjustments to the firing of Zhuyuan, will accurately hit the enemy ship in the fifth shelling.

However, in this live-fire artillery drill, two artillery commanders and their crew members made the first hit.

This means that the first shell hits the enemy ship, then the whole ship has a total of 12 main guns, using a unified caliber, you can achieve a salvo of 12 main guns in the second round, which means that the second round of shelling will cause heavy damage to the enemy ship, and even if you are lucky, you will shoot a fatal through-hit bullet and sink the enemy ship.

This plays a huge role and is of great significance in naval warfare.

Therefore, Li Weiguo made an exception and personally awarded the two gunners and his crew medals, asking them to pass on their experience to other comrades-in-arms to improve the combat effectiveness of the Chinese Imperial Navy.

After the award, Li Weiguo visited the latest submarine of the Imperial Chinese Navy, the Swordfish.

The Swordfish, the first of the Imperial Chinese Navy's newest swordfish-class submarines, was launched two years ago and is still in sea trials.

This is the longest trial submarine in the history of the Imperial Chinese Navy, and two of the Swordfish class are currently being built over a period of five years.

This is because as the armament technology of the Chinese Empire continues to advance, submarines need to install more and more new equipment, and more and more thorny problems are encountered.

In the past, the Chinese Imperial Navy built submarines in a few months for a few hundred tons and a year and a half for a thousand tons.

During the Spanish-American War, in order to quietly transport supplies to Havana to support the Spanish army, the Imperial Chinese Navy developed the Seahorse-class submarine, which was a submarine for the purpose of carrying cargo, with an underwater displacement of 4,000 tons, which also opened the prelude to the construction of 4,000-ton large submarines by the Imperial Chinese Navy.

Due to the Imperial Chinese Navy's lack of attention to submarines, there was no order for submarine construction after the Great White Shark-class submarines, and later, if it were not for Li Weiguo's first hand, the top brass of the Imperial Chinese Navy would still not attach importance to the development of submarines, until Japan and the United States built submarines on a large scale and concentrated their deployment to the Pacific Ocean, which aroused the great attention of the Imperial Chinese Navy and produced a sense of crisis.

Although there have been no submarine orders for a long time, because the research and development of submarine equipment is directly funded from the Imperial Academy of Sciences, and does not need to be funded from the Admiralty, the submarine experts led by Holland are not idle, even if there is no order, they still have enough funds to develop new submarines, so the submarine technology of the Chinese Empire is not only not lagging behind, but still leading European and American countries.

Under the influence of the doctrine of giant ships and artillery, even though the Admiralty was forced to start building submarines, it demanded that submarines have large tonnage, high speed, long range, fierce firepower, and so on.

The Navy did not scare Holland and others by making such a request, but instead used it as a motivation to design and build an underwater giant that basically conforms to the requirements of the Navy on the basis of the Great White Shark-class submarine and the Seahorse-class transport submarine, which is the Swordfish-class submarine.

Swordfish-class submarines, taking the first boat, the Saurfish, as an example. The main dimensions of the submarine are 2,300 tons of light load displacement on the surface, 2,800 tons of normal surface displacement and 4,800 tons of underwater displacement.

This class of submarines is designed and built with the Great White Shark class and Seahorse class as the mother type, and a very prominent feature in the design is that it attaches great importance to its underwater performance.

Of course, this is also forced by the bigwigs of the Admiralty to have no choice, and if it fails to meet the requirements, the Admiralty will have a reason to reduce its investment in submarines.

Under the requirements of the Admiralty's high speed, high firepower, and high endurance, Holland led his team to resolutely withstand the pressure and finally designed the Swordfish-class submarine.

Accompanied by the admirals, Li Weiguo stepped on the submarine Swordfish.

Standing on the shell of the Swordfish submarine is like stepping on the back of a huge whale.

It is obvious that the shape of the Saurfish was designed by Holland to be streamlined, which is to reduce the resistance of underwater navigation, and the shape is very close to the teardrop-shaped submarine of the 21st century, and it looks plump.

Of course, what attracted Li Weiguo's attention the most was the two long antennas, from the bow to the stern, which were supported by the ship island in the middle, forming a huge triangle.

Obviously, this is the radio system, and with this advanced equipment, the Admiralty of the Chinese Empire can know the location of each submarine for the first time, and in wartime, it will play a huge role.

The bow of the Swordfish-class submarine is more rounded and blunt, and the upper deck line from the podium enclosure to the bow is almost parallel to the waterline.

These characteristics not only show the progress of the Imperial Chinese Navy in submarine design, but more importantly, it reflects that the Imperial Chinese Navy has fully absorbed the experience and lessons of submarine warfare since the "dark war", abandoned the traditional design idea of submarines focusing on surface navigation, and adopted the guiding ideology of submarine design focusing on underwater navigation.

Objectively speaking, the design and construction of the Swordfish-class submarines reflected the changes in the perception of submarines in the Imperial Chinese Navy.

In the past, Li Weiguo did not agree to install artillery on submarines, and advocated that submarines only use fish and radium to fight underwater.

However, in the past, the submarine technology of the Chinese Empire was immature, and there was no radio system, no oxygen reserve system, no high-performance battery system, short range of fish and radium, slow submarine speed, etc., which forced the submarine to sail on the surface for a period of time and use deck guns as a means of attack.

Nowadays, the Chinese Empire has made rapid progress in science and technology, and all kinds of epoch-making high-tech equipment have been successfully developed one after another, such as sonar, radio, high-performance battery packs, high-power diesel turbines, high-power air compressors, and so on, which have greatly improved the equipment and performance of submarines, so that the submarines of the Chinese Imperial Navy have finally gotten rid of surface warfare and completely realized underwater warfare.

Li Weiguo and his entourage entered the interior of the submarine, because the tonnage of the submarine is huge, the internal space is very spacious, but the number of combatants has not increased, and the extra space is actually used to reserve more air, because the more air, the longer the underwater diving time, and the higher the safety.

Under the introduction of the captain, Li Weiguo successively visited the bow and radium compartment, the forward battery compartment, the combat command compartment, the rear battery compartment, the main engine compartment, the power plant control cabin, the stern torpedo cabin, the crew rest compartment, the dining compartment, and so on.

In the bow Fish Radium cabin, six 533 mm Fish Ray launch tubes are arranged. These fish radium launch tubes are MK-54 type hydraulic fish radium launch tubes, developed by the Jiangnan Manufacturing Bureau, which can launch MK-14 type, MK-27 type and other 533 mm fish radium, of which MK27 fish radium, is a rocket-boosted extended range fish radium, which is the first in the Chinese Empire.

However, because rockets are a new field, proposed by Li Weiguo, the Imperial Academy of Sciences initiated research, but the miniaturization of rocket engines is a difficult problem, so the rocket-boosted extended-range fish radium is only a test weapon, and its purpose is to sneak attack enemy ships at a longer distance to ensure that their submarines are not discovered by the enemy.

The Saury-class submarines are equipped with a total of eight 533 mm Fish Radium launch tubes, including six in the bow and two in the stern. The bow radium compartment also doubles as a spare torpedo compartment, a crew living and living compartment, and a bow emergency escape compartment.

The reason for setting up the escape pod is because in the past ten years of the Chinese Empire, submarine accidents have continued, a large number of elite submarine officers and men have died in the line of duty, and mankind's fear of the sea has made the navy have to study the escape system.

In fact, the escape system is very primitive, that is, the use of the Fish Radium Launch Tube, at the critical moment, the bed of the personnel is closed, and it can be launched through the Fish Radium Launch Tube.

Li Weiguo saw that the bed in the rest compartment of the submariner crew was like a coffin, but it was as round as a fish radium, and it could be used as a fish radium at a critical moment, and it could be shot out directly to escape for life.

In the front battery room, there is a deck, the space of the second cabin is divided into two floors, the upper floor is the officer's cabin, the officer's dining room, the captain's room, the officer's bedroom, the sergeant's living room, the radio communication room and the sonar room, etc., and the lower layer is arranged with the front battery pack, which is composed of 252 battery cells.

The combat command cabin is located in the middle of the submarine of this class, and the arrangement of the combat command cabin in the boat has been improved, and the control parts and combat command positions of the submarine of this class are arranged on the same deck in the combat command cabin. The periscope is arranged in the combat command cabin to the bow side, the right side of the periscope is the combat command position, the left side is the control command position, and the wheelhouse is arranged in front of the periscope.

In Li Weiguo's view, the arrangement of the combat command cabin of the Swordfish-class submarine in this way can enable the captain to use the periscope to observe while taking into account the operational command inside the boat, thus ensuring that the captain's operational command and action are faster and easier. However, the disadvantage of this arrangement is that due to the limited area of the combat command cabin, when all the personnel in the command and control cabin are in their respective positions, the cabin appears to be a little crowded.

The rear battery compartment is divided into two floors by a deck, the upper floor is the galley, the crew dining room, and the crew living cabin, and the lower floor is arranged with the rear battery pack, which is also composed of 252 battery cells.

There is no deck in the main engine room, and three longitudinally arranged X-type 2-stroke diesel engines and main propulsion motors are arranged.

There is a relatively small space in the power plant control compartment, which is equipped with the control panels of the entire power plant.

The stern torpedo compartment is equipped with two 533 mm stern torpedo tubes, and the stern torpedo compartment functions the same as the bow torpedo compartment, which also doubles as a spare torpedo compartment, crew accommodation compartment and stern emergency escape compartment.

What aroused Li Weiguo's interest the most was the underwater acoustic equipment on the Swordfish-class submarine.

The underwater acoustic equipment of the Swordfish submarine uses the active acoustic system and passive sonar system newly developed by the Chinese Empire, which is more complete than the sonar system used by the Egret-class anti-submarine destroyers five years ago, and its performance has also been greatly improved and improved.

The Saury-class submarine uses a twin-shaft twin-propeller propulsion method, and its maximum surface speed is 18 knots, and because the boat is equipped with two sets of large-capacity battery packs, when the Saury submarine adopts the one-hour discharge system, the maximum underwater speed of the submarine is 18.3 knots.

In order to meet the requirements of the military to become too much, Holland really spent a lot of energy shooting.

Among them, in terms of endurance, the Saury submarine has a cruising range of 10,000 nautical miles when sailing at a speed of 10 knots in the surface state, and a cruising time of 72 hours when sailing at a speed of 3 knots in the underwater state.

These 72 hours, which is three days, shows that the Saury submarine can operate underwater for three days.

This kind of diving time completely broke the doubts of the Admiralty, and made them all shut up, and they could no longer deny the role of submarines on the grounds that they were short of diving time and that they were easy to catch and sink enemy ships when they were forced to surface.

Due to the huge tonnage of the swordfish-class submarine and the use of the hardest and most corrosion-resistant special steel of the Chinese Empire, its safe diving depth exceeded 150 meters for the first time, which is about 90 meters higher than the safe diving depth of the fleet-type submarines built by the navies of Europe and the United States, which will provide huge protection for the Chinese Imperial Navy in battle.

According to the intelligence obtained by Li Weiguo, at present, the Entente group has also begun to learn anti-submarine, but their anti-submarine smashing eggs are still targeting the Great White Shark-class submarines of the Chinese Empire, which can only be counter-50 meters deep.

In this way, if they run into the submarine Saury, there is no way to do it at all.

There are many advantages of the Swordfish-class submarines, for example, the previous submarine design of the Imperial Chinese Navy was to set up both high-pressure and low-pressure air blowing pipes in the main ballast water tanks. When the submarine floats from the submersible state, first use the horizontal rudder, vertical rudder and the speed of the submarine to make the submarine float to the periscope depth, and then blow off the buoyancy tank and the main ballast water tank with high-pressure air, when the superstructure of the submarine is exposed to the water, stop the high-pressure air blowing, and replace it with low-pressure air to continue to blow out the remaining seawater in the water tank.

However, on the Swordfish-class submarines, the main ballast water tanks and other water tanks are not equipped with low-pressure air blowing tubes, but the exhaust gas of the main engine is used to blow out the remaining seawater in the ballast water tanks. During the design of the Swordfish-class submarine, Holland took full advantage of this advantage, thereby simplifying the blowing equipment on the boat.

In fact, the Admiralty is most concerned about the combat effectiveness of the swordfish-class submarines, and even Li Weiguo couldn't help but ask.

Soon, a technician explained to Li Weiguo that the MK-54 hydrostatic radium launch tube used in the swordfish-class submarine was used to launch the fish radium in the underwater state, and when the submarine used the MK-54 hydraulic fish radium launch tube to launch the fish radium in the underwater state, it mainly relied on the water pressure generated by the piston in the hydraulic cylinder when moving at high speed to launch the fish radium, which could ensure that there were no bubbles floating up when the fish and radium were launched, which increased the concealment in the process of launching the torpedo.

In addition, the MK-54 hydrostatic Fish Radium Launch Tube can launch Fish Ray at a large depth, thus increasing the flexibility of the Saury submarine in underwater operations.

It should also be pointed out that the MK-54 hydropressure Fish Ray launch tube adopts a linkage safety device, when the front cover of the launch tube is slightly opened, the back cover cannot be opened; Conversely, if the back cover is slightly opened, the front cover will not open either.

This safety device represents a significant advance in the technology of submarines of the Imperial Chinese Navy, which has previously been involved in such accidents that have led to the sinking of submarines. Submarines in Europe and the United States have repeatedly had such accidents, and there is no solution yet.

In short, the overall performance of the Swordfish-class submarine is very good, but there are also various problems in the sea trials.

Of course, the source of the problem is basically the problem of new equipment. For example, the transistors in radio equipment and sonar equipment are easily affected by the humidity of the weather at sea, which is a problem that is difficult to solve for the time being, and can only be replaced at any time by preparing more accessories.

In the end, Li Weiguo dined with the soldiers in the dining room to enhance the feelings of the monarchs and soldiers until after the evening, and he left satisfied. (To be continued.) )
