Both the destroyer and the cruiser were used as warships for a long time in the future, and their technical content reached the limit of Chen Shao's current time. And in the hull, a lot of space for transformation is reserved to facilitate future transformation work.

Unlike the first generation of destroyers and cruisers, the second generation pays more attention to its outstanding single capabilities. Originally, there were also main guns, but now the cruiser retained only two in front of the bridge, and one in the back was replaced with anti-aircraft fire. The destroyer was more thorough, leaving only one main gun, the other two were dismantled, and all the space was reserved for anti-submarine installations.

Because the main guns on both warships are used defensively, they are basically useless except for land attacks. However, among the battleships designed for Germany, because of the high elevation angle of the battleship's main guns. This gave a wake-up call to the main guns of cruisers and destroyers, which could also be anti-aircraft. This is by no means a utopian dream, Bismarck's main guns can be anti-aircraft, and there is no reason why small-caliber artillery cannot.

Therefore, when designing the cruisers and destroyers of the second generation, the remaining main guns were made to be used for both high and flat purposes, and they could be used as anti-aircraft firepower. The caliber of the main guns has not changed, the cruiser still has 203 guns, and the destroyer has 155 guns. It's just that the triplet has become a double. The main reason is that the high-level dual-use, and the triplet cannot meet the requirements of high-level dual-use.

The anti-aircraft machine guns were all gone, and all were replaced with artificially controlled phalanxes. Even the destroyers are equipped with two phalanxes, which can not only defend the aircraft, but also strike at surface targets.

In the development of the six-barreled Gatling, many models have been made. If it weren't for logistical problems. Now there are a large number of equipped troops, Hummer plus Gatling, that kind of lethality, absolutely terrifying. However, the caliber will be much smaller than the phalanx on the ship, generally 12.7, and there is enough space on the ship, which is 20mm.

The air defense capability of cruisers is the second line of insurance for the safety of aircraft carrier battle groups, and has always been a key construction target of the Navy. Not only in the phalanx, but also in the anti-aircraft artillery, the research has not stopped. The first generation of anti-aircraft guns can hit an altitude of more than 8,000 to 10,000 meters, while the requirements of the second generation are much higher, at least 15,000 meters. And this is only a requirement for small-caliber anti-aircraft guns.

The destroyer is the main weapon of destruction against the enemy submarine, and after the two main guns are removed, in addition to the two phalanxes, the deck is placed with depth charges. However, on the destroyer, there are four 533 torpedo tubes on the left and right sides of the hull.

In order to improve seaworthiness, but also to be able to better cooperate with the aircraft carrier in ocean-going operations. In terms of tonnage, both warships have been greatly improved. The displacement of the first generation destroyers was just over two thousand tons, and by the second generation the displacement had increased to four thousand tons. The tonnage of the cruiser also increased to fifteen thousand tons. The tonnage is larger, the speed has not decreased, but has increased a lot, and the latest steam turbines are used, and the power of the capital ship is the same system. Originally, the speed of the destroyer was 34 knots, but now it has jumped to 40 knots, and the speed of the cruiser has also been greatly improved, and it has also reached 38 knots.

And on each destroyer and cruiser, an early warning radar will be installed. Because the distance of the fleet is one or two hundred nautical miles away when it is exercised, this can also increase the warning range of the radar and ensure the safety of the area as much as possible.

As for the second-generation frigates and landing ships, no new warships have been designed this time. However, after the Shang-class submarine, another type of submarine is under construction. This is a more massive conventionally powered submarine, which belongs to the third generation of submarines in China. This type of submarine is a Zhou-class submarine with the designation Q-3. For the first time, the displacement of the Shang-class submarine exceeded 1,000 tons, while the Zhou-class submarine also exceeded the displacement of 2,000 tons, and the underwater displacement was almost 3,000 tons. This type of submarine is the largest in the history of the future.

The same is the use of water drop streamline, the tail of the X-shape, so that its underwater speed is greatly increased. And a lot of work has been done on the propeller, and the blade surface of the propeller is ultra-precision polished, and any small bumps that may cause air bubbles are ground to be extremely smooth. Submarines are underwater, and the two places where noise occurs are the propellers and the engines. The problem with the propeller requires a very precise lathe grinding, a bump about the size of dust, which causes bubbles when turned. The formation of bubbles is easily detected by enemy sonar.

On the engine, the noise reduction treatment is even more fine. The entire engine was placed on a specific sponge body, so that it did not come into direct contact with the hull of the submarine itself. And in the engine room, a lot of soundproofing devices were made. When the engine is running, the ears can't hear the slightest movement outside. Even the sonar technology of World War II is difficult to detect. Because of the sonar that can be detected, sonar personnel cannot tell whether it is a sonar signal from a whale or a sonar signal from a submarine.

Inside the submarine, a large number of electronic devices have been transplanted, mainly about sonar electronics. In order to strengthen the connection between the submarines, new sonar equipment was installed. However, the submarine itself still has no way to solve underwater radio communication, and it has to drag the radio receiver to use radio contact. However, this also greatly increases the likelihood of exposure. It will not be used in non-safe areas and emergencies.

Chen Shao also had no better way to deal with the problem of submarine communication, and in the new era of later generations, there was no better solution to submarine communication. Even if there is, it is not something that Chen Shao, who is a small citizen of Shengdou, can know.

However, this type of submarine made Chen Shao very satisfied, especially in terms of tonnage. Not only has the combat effectiveness been greatly enhanced, but the submariners' livelihood has also been greatly improved. Large tonnage means an increase in space, and on this type of submarine, the number of torpedoes has reached 36, and there are six torpedo tubes, four in the front and two in the rear. There are 30 bombs in the front tubes and 6 in the back. The specifications of the torpedo have not changed, the same is the 533 torpedo, and the type is also about the same.

And life on submarines has also changed a lot with the increase in tonnage. The most direct place is the living space of the crew, originally each person only had one bed that could not be turned over, or two people shared a bed, and there was no private air force at all. Each crew member now has their own bed and their own cupboard to keep their personal belongings.

The food has also been greatly improved, and the food pantry has an extra cold compartment to store more meat and try to preserve fresh vegetables. The number of canned beverages that can be carried has also increased. Six meals a day are abundant. I can also try to change the taste every day, saving myself from eating and eating.

Chen Shaoke didn't want his submariners to look like savages every time they went ashore. While ensuring combat effectiveness, Chen Shao also instructed the design team to improve the lives of submariners as much as possible. As a whole branch of the military, submariners are the most tiring and boring of the military, and Chen Shao also takes care of their daily life on the boat as much as possible.

As the combat support of the fleet, supply ships have always been the key construction targets of the Chinese Navy. It is not only necessary to meet the requirements in terms of transportation volume, but also to meet the emergency supply operations on the battlefield in terms of supply speed. In order to cope with the new war situation, the latest supply ships were built in a strange shape with four hangers, like a small dock. Moreover, two 50-meter oil pipelines can stretch out on it, which can quickly deliver fuel to warships. The crane is used to lift ammunition and daily necessities for the warship faster, as long as the two ships are 30 meters apart, keep the same speed and parallel, they can quickly complete the replenishment operation.

The transport volume of the supply ship itself is also very powerful, and generally an aircraft carrier battle group with two supply ships can conduct long-term ocean-going operations. It is enough to ensure the safety of the supply ship during this period. Because the supply ships do not have good protection capabilities, they can only rely on the protection of the fleet.

Moreover, the new type of supply ship is also built into an integrated supply ship, as long as the materials needed by the fleet can be found in it. Its pride is that he has a big belly and a load capacity larger than that of an aircraft carrier.

In accordance with the requirements of the complete formation of the Chinese Navy, a single aircraft carrier battle group has the following number of ships: one Imperial-class aircraft carrier, four air defense cruisers, four anti-submarine destroyers, four frigates, two supply ships, and two submarines.

However, the submarine did not meet the requirements of the ocean, and the speed could not keep up with the surface ships, so the submarine was cut. A fully formed single aircraft carrier battle group has a total of fifteen warships. This is a non-wartime alert cruise is a compilation. In wartime, the establishment will be greatly strengthened, the aircraft carrier battle group will be turned into an aircraft carrier fleet, and on the basis of a single aircraft carrier battle group and one Imperial-class aircraft carrier, two more First Emperor-class aircraft carriers will be added, and two other warships will be added each. In this way, an aircraft carrier squadron will have three aircraft carriers, plus other auxiliary ships, for a total of 25 warships.

Battleships will form battleship fleets, and will also be equipped with cruisers and destroyers, as well as supply ships, in the same number of equipment as carrier battle groups. Battleships generally carry out attack missions on land alone, cooperate with aircraft carriers to support landing operations of marines, or form a joint attack fleet with several carrier battle groups.

The Empire-class aircraft carriers, like the First Emperor-class aircraft carriers, will continue to be built, forming a high-low combination. And the general-class battleships will not be built too much, according to Chen Shao's estimate, four is already a lot. And Chen Shao also plans to sell all the Kunlunshan-class battleships, because there are too many battleships, which will increase a lot of logistical burden, not to mention that the navy itself does not need a large number of battleships.

The funds for the construction of the new ships this time were all obtained from the sale of warships, and as for the construction of the home port of the domestic fleet, it was handed over to other departments and appropriated by the Ministry of Finance. Because there are still many warships to be built in the future, relying on the navy itself can no longer pay for the construction of the military port.
