Huang Zhe continued: "The second problem is that our shipyard has limited production capacity. Now we have two shipyards, namely Tianjin Shipyard and Qingdao Shipyard, but only Qingdao Shipyard has the ability to build 10,000 tons of warships. However, Qingdao Shipyard now has only three docks for building 10,000 tons of warships. One of them is a maintenance dock for us to cross warships. Therefore, we can only build two 10,000 tons of warships at the same time. The construction cycle of a 10,000 tons of warships is generally about 2 years. The launch is about half a year, and it is in the dock for about 16-20 months. Theoretically, in this five-year cycle, we can only build 8 10,000 tons of warships at most, but considering that we still have a large number of prisoners to repair and warships to maintain and repair, in fact, with our current production capacity, we can only build 4 10,000 tons of warships."

Wang Hailong was startled and said, "Are you so few?"

Huang Zhe said: "In the second five-year plan, two docks that can build 20,000 tons of warships will be expanded in Qingdao Shipyard, but this project will take about three years to complete. In addition, the construction of a shipyard in Dalian, the transformation of the Jiangnan Manufacturing Bureau in Shanghai and the establishment of the Jiangnan Shipyard are all included in the 141 plan. If these plans are completed, our shipbuilding capacity will have a qualitative leap. In theory, we can achieve the ability to build 6-8 large warships at the same time. However, the Dalian Shipyard is still choosing and making it possible to start production and build large warships at least 3-4 years. The renovation of the Jiangnan Shipyard will also take 1-2 years. Therefore, from the perspective of production capacity, our large-scale construction of large warships should be in the next five-year cycle."

Wang Hailong opened his mouth, as if he wanted to say something, but he still didn't say anything.

Huang Zhe also said: "The last problem is that the supporting capacity of shipbuilding is insufficient. The shipbuilding industry is a huge system industry with hundreds, but still thousands of supporting industrial systems. It cannot be solved by just one shipyard. In the first five-year plan, we have solved most of the supporting systems. The 2103 special steel developed by the steel mill in 1906 successfully solved the problem of steel for warship keels, which is a major breakthrough. However, there are currently three most important supporting systems for warships, power systems.

We do not have the ability to produce the system, armored steel, and main guns independently. It seems that we have an agreement with Germany to jointly develop steam turbines, and now it has reached the stage of formal loading. According to the agreement, Germany should help us establish a steam engine factory, which can not only produce steam turbines, but also boilers and reciprocating steam engines. This project has been included in the 141 plan, so the power system is expected to be resolved within this five-year cycle, but armored steel and large-caliber main guns are currently only able to rely on imports.”

Wang Hailong said: "It turns out that we still have so many things that are not good. Newspapers blew up this monopoly that broke through foreign countries and achieved the international advanced level. They are all deceptive."

Shang Jinfeng said: "Of course it's not a lie, but we need to make up too many lessons."

Zhang Wei said: "With the steam turbine, why do you need a reciprocating steam engine?"

Huang Zhe said: "The technology of the duplex steam engine is mature and has low cost, so it can still be used on civilian ships."

*** said: "Where is the diesel engine? Didn't we have a diesel engine factory?"

Huang Zhe said: "At present, the power of diesel engines is not high. They are mainly used on vehicles and small warships. However, it takes at least 15 years of research and development to be used on large warships."

Wang Hailong said: "Let me tell you, what kind of warship can we build now? Is there any design plan?"

Huang Zhe nodded and immediately ordered someone to lift out several picture boards from the preparation room next to the conference room and hang them on the display wall. When everyone saw that they were drawing a plane, side elevation, and renderings of a warship.

Huang Zhe came to the drawing board, took a pointer, and said, "This is the drawing of the next type of battleship we designed. Of course, it can be regarded as a modification of the Ganjiang class. The main parameters are: the total length is 139 meters, the width is 19.2 meters, the draft is 8 meters, and the estimated displacement is 13500-14,000 tons. The main gun is still 8 280 mm main guns, divided into 4 double turrets, and the load-bearing structure is arranged along the central axis. The armor is 300 mm main armor, the headquarters and main gun turret are 350 mm, the auxiliary armor belt and dome armor are 150 mm, and the deck armor is 80 mm. The power is the same as the Ganjiang class, and the maximum speed is 20 knots, which is 0.5 knots less than the Ganjiang class."

Wang Hailong said: "Since it is an improvement type, it must have some changes from the Ganjiang level, right? What are the differences between the original Ganjiang level after improvement?"

Huang Zhe said: "There are two main changes, first of all, the range. Since the Ganjiang-class battleships were arranged in order to meet the arrangement of 8 main guns, in this era, the 12,000-ton battleship only arranged 4 main guns, so they can only compromise on the range. The Ganjiang-class coal load capacity is only 900 tons, and the maximum range is 12 knots and the speed is 3,600 nautical miles. In this era, this range can only be regarded as the level of a port defender. However, when we designed this type of warship, we did not have the intention of ocean-going combat.

I hope that the main thing is to fight in the offshore area, so the impact of this range disadvantage is not great; but considering that we have occupied Borneo now, the range of the navy will include the entire South China Sea and Java Sea in the future, the weakness of the Ganjiang-class voyage will be expanded and become the biggest shortcoming. Therefore, the coal storage volume of the new battleship increased to 1,300 tons, and the range can also be increased to 4,500 nautical miles, which can basically meet the current combat requirements of our navy."

Wang Hailong nodded repeatedly and said, "This improvement is good. Other Ganjiang-class performances are good, and it is indeed a little less range." Wang Hailong commanded two Ganjiang-class battleships to participate in the Natuna Islands Naval Battle, and the long-distance raids reached more than 5,000 kilometers. Since the fleet was running at a speed of 15 knots, the two Ganjiang-class battleships carried out coal replenishment twice on the way. Although there was a Yueyang ship in the naval formation at that time, and the radar on the ship could use the ship's radar to scan the surrounding situation, no unexpected situations occurred, but after the end of the Far East War, the five modern warships would gradually withdraw from the front line and retreat to the second line, so the weakness of the Ganjiang-class insufficient range would become a major shortcoming of the fleet.

In fact, the improved battleships can only be considered as passing the voyage to 4,500 nautical miles. To truly achieve ocean-going combat, the range must be increased to at least 5,000 nautical miles. However, the main range of activities of the East China Navy is still in the South China Sea area. Although it is not considered near-shore combat, it still does not meet the standards of ocean-going combat, so this range is sufficient.

Huang Zhe continued: "The second major change is firepower, of course, mainly the firepower of the secondary gun. The Ganjiang-class secondary gun is 8 dual-mounted 155mm caliber guns; and 8 dual-mounted 100mm caliber rapid-fire guns, and then 6 dual-mounted 50mm caliber rapid-fire machine guns. However, according to the reaction of the soldiers on the ship, such a firepower level is too large, and the 120mm caliber intermediate firepower is lacking between the 155mm cannon and the 100mm cannon, and 75mm rapid-fire guns are also lacking between the 100mm cannon and the 50mm machine gun. These limitations have led to the Ganjiang-class battleships being in the middle and close range.

When targeting, there is some lack of firepower. Our previous consideration was to simplify the caliber of the artillery to reduce the pressure of logistics and the dispatch of warships. However, simplifying logistics is based on the premise of not damaging the firepower of the warship. Therefore, this time, the main gun and 155mm caliber secondary gun remain unchanged. The other guns are 4 dual-mounted 125mm caliber guns, 4 dual-mounted 100mm caliber guns, 6 75mm caliber rapid-fire guns, and 6 dual-mounted 50mm caliber rapid-fire machine guns. In this way, the firepower arrangement is formed. Of course, the effect of the whole depends on the actual combat results. The only criterion for testing the quality of the weapon is."

Wang Hailong also nodded repeatedly. The firepower levels of the Ganjiang-level are too different, which is indeed a problem. Although this has indeed simplified the logistics pressure, it has also caused unnecessary waste in the war. For example, the power of the 100mm cannon is somewhat insufficient for enemy warships below 3,000 tons, while the power of the 155mm cannon is too strong, and the 125mm level cannon is just right. For warships below 500 tons, the power of the 100mm cannon is too high. The 50mm caliber rapid-fire machine cannon is a little worse, and the 75mm level cannon is required.

Of course, in this way, the original level 4 artillery became level 6, the logistics pressure increased, and the internal dispatch of warships was more complicated. Therefore, this is actually a matter of choice, and the pros and cons of the whole can only be found in war. Although the time travelers are clear about the development direction of warships in this era, these details are not clear, and corresponding experience is required. The People's Army Navy is still a bit naive in these aspects.

At this time, Wang Hailong said again: "The Ganjiang-class battleship and the Chitu-class armored cruiser adopt the same ship type, that is, the idea of ​​one type and two ships. Since the Ganjiang-class battleship has improved, is there any improvement in the Red Rabbit-class armored cruiser?"

Huang Zhe nodded and said, "Of course there are." As he said that, he ordered people to change a set of drawings and said, "This is the improved type of the Red Rabbit-class armored cruiser. It is the same type as the new battleship. It is a little less wide, only 18.3 meters and a draft of 7.5 meters; the estimated displacement is between 11,000-12,000 tons; the main gun is still 8 200 mm main guns, divided into 4 double turrets, arranged along the central axis with a back-loaded structure; the armor is, the main armor is 180 mm, the headquarters and main gun turret are 220 mm, the secondary armor belt and dome armor are 100 mm, the deck armor is 50 mm, the maximum speed is 22 knots, and the range is 12 knots and 5400 nautical miles."

Wang Hailong said: "These data are generally a little enlarged, and there is no big change, and the combat power has not been significantly enhanced. Only the range has increased by 400 nautical miles, but the actual significance of increasing such a little range is not very big."
