readx; The seventh phase of the Chinese Navy's development plan was quickly approved, for which the navy received additional funds for naval shipbuilding in the 1932 budget allocation, plus the wartime shipbuilding plan funds that were urgently allocated during the wartime, and the two funds together provided sufficient funds for the start of the seventh phase of the navy's development plan. Pen, fun, and www.biquge.info

Originally, the navy had a fixed amount of military spending, but whenever there was a large-scale plan to replenish warships, the navy's annual permanent military expenditure alone could not meet the demand, and a certain amount of special funds had to be allocated from the financial budget to fill this gap.

After the funds were paid, the seventh phase of the Navy's development plan was soon fully launched, the first plans included a 25,000-ton light battleship, a treaty-type heavy cruiser, two lightning light cruisers, three destroyers, in addition to the capital ships of these surface fleets, there were plans for the construction of three medium submarines, and a large ocean-going submarine.

When the first batch of plans is initially implemented, the second batch of plans will continue to build combat warships, and will also build large-scale auxiliary vessels, such as full-time minelayerers, minesweepers, fuel supply ships, ammunition logistics supply ships, and transport ships. The Chinese Navy has gradually moved towards the open sea, and is no longer the original coastal navy, and to go out to the open sea to fight, there must be a large number of non-combat auxiliary warships in the fleet, especially high-speed supply ships are indispensable, otherwise it will not be possible to go out to the Pacific Ocean to fight, especially aircraft carriers, if they go out to the open sea to fight, the consumption of fuel will be very large, and they must be replenished once in a period of time, otherwise those planes will not have aviation fuel to fly.

The number of these non-combat auxiliary warships is quite large, and if we add non-main warships such as naval defense ships and coastal patrol ships, then the Seventh Development Plan of the Navy can be regarded as a comprehensive and complementary plan. The core of the plan is not to say how many battleships or aircraft carriers to build, but to build enough auxiliary ships to maximize the combat effectiveness of the Chinese Navy's existing four battleships and six aircraft carriers.

Even the 25,000-ton light battleship is used as an auxiliary ship in the strategic planning of the Chinese Navy, and its mission is very simple, that is, to accompany the aircraft carrier formation in ocean-going battles and provide all-round cover support for the aircraft carrier formation, including close-range artillery combat missions at night and in rainy and foggy weather, including air defense missions against incoming aircraft groups, and when the aircraft carrier formation carries out a land-to-shore strike, its large-caliber naval guns also have to support the land.

The Admiralty has set so many goals for it, but it has not given it the task of participating in the decisive battle of the fleet's artillery, and although its tonnage will be as high as 25,000 tons, the Navy does not intend to turn it into a battleship in the traditional sense.

Because this light battleship may be the only new capital ship built in China in the next seven or eight years, so the cost of the naval department is not too restrictive, they only ask for the best surname Neng, in order to make this light battleship meet the needs of the Admiralty, the shipyard department from a large number of design plans to put forward the final plan.

Although the final selected scheme can be called superior, but the technical requirements are also extremely demanding, the design code is the predetermined number of this capital ship that has not yet been designed: BB-08, with a standard displacement of 27,000 tons, of course, the surface announced is 25,000 tons. In order to meet the strict requirements of the navy, the design plan of the Department of Naval Administration is completed, and the standard displacement is expected to be as high as about 27,000 tons, not only the displacement of this BB-08 warship exceeds the limit of the naval treaty, in fact, almost all of the treaty-type warships designed by China exceed the limit of the treaty, but the excess number is not large, and the concealment is good enough, the displacement of the warship exceeds the standard This kind of thing is only known to a few senior generals and designers, and most people inside and outside do not know. After all, it is impossible for them to measure it themselves, even if they want to side the Chinese Navy.

It is expected to use three triple nine 12-inch 50-caliber naval guns, because the Chinese Navy does not have a reserve of new naval guns of 12-inch caliber, so to build this BB-08, it is necessary to develop a new naval gun, but China does not plan to bite hard, but has already made contact with France, and the French are now also developing new main guns for their new generation of capital ships, Dunkirk-class light battleships, although the caliber they selected is thirteen inches, and they also intend to use a two-seat quadruple installation, However, some specific naval artillery technologies can still cooperate with each other.

Although China's industrial base is weak, as one of the only four countries in the world that uses 16-inch naval guns, after more than 10 years of technological accumulation, China's technological accumulation in large-caliber naval guns has been very perfect, and it is now able to develop and manufacture 16-inch naval artillery systems. After the life of the 16-inch guns on the four battleships was exhausted, there was no longer any need to import them from the United States.

However, it is also funny to say that China now has no pressure to manufacture 16-inch naval guns, but it is much more troublesome to make new 12-inch or 14-inch naval guns, because for 12-inch and 14-inch naval guns, the Chinese Navy has not studied much, but in the early years, it studied more than a part, and manufactured some of them as coastal defense guns, but it is still very difficult to develop a naval gun with an advanced surname just by relying on these.

Because the Admiralty requires that the new main guns equipped on the BB-08 battleship be comparable to the old 14-inch naval guns or even 15-inch naval guns equipped in the navies of various countries. The caliber should be small, but it should also be able to pose a sufficient threat to the enemy's battleships.

If the new naval guns cannot pose a threat to the enemy's battleships, then the Chinese Navy might as well directly use the mature eight-inch naval guns, and if a battleship is equipped with more than 16 eight-inch naval guns, it is enough to suppress the enemy's heavy cruisers by relying on numerical superiority.

Although the new naval gun is still shaky, the Gun and Artillery Section under the Department of Ship Administration has already set detailed technical objectives for this new naval gun: the caliber should be 12 inches, the length of the barrel should be 50 times the caliber, and when 510 kg armor-piercing shells are used, the muzzle velocity of the gun will be 800 meters per second, the rate of fire will be two rounds per minute, and the life of the barrel will be 250 rounds. At a distance of 20,000 yards, it is capable of penetrating at least 320 mm of side armor and at least 75 mm of horizontal armor.

If the new naval gun can meet the design goals set by the Guns and Artillery Section of the Naval Administration, then this new naval gun will be able to surpass the old 14-inch naval guns of various countries, and will give the BB-08 the ability to threaten enemy battleships.

For this reason, the Shanghai Arsenal has carried out intensive cooperation with the French side, China's 12-inch naval gun technology is inexperienced, so the French are no better, and the two joint research and development can also accelerate the development of new naval guns.

In terms of protection, the Navy requires this new warship to be able to effectively resist the blows of the enemy's eight-inch artillery shells at a combat distance of 10,000 yards to 27,000 yards, and the horizontal protection is required to be able to protect against the strikes of the 350-kilogram aviation armor-piercing bombs currently equipped in the Chinese naval aviation, so the thickest part of the side armor is 250 millimeters, and the thickest part of the horizontal armor is 127 millimeters.

In addition to the two vital data of naval guns and protection, the power system of BB-08 is also a major project, which is expected to use the SL930 steam turbine system provided by Shanghai Power Company, and this power system is a research and development plan proposed by Shanghai Power Company in the past two years, and the goal of research and development is to provide superior ship steam turbines for various types of capital ships of the Navy in the late thirties and even to the forties, and the installation time is expected to be around 1935.

Based on the general type of power system on large warships, in fact, this SL930 steam turbine system can not only be provided to BB-08, but also can be provided to new heavy cruisers, aircraft carriers, etc., after all, this power system can be superimposed to increase power acquisition, larger ships use more oil-fired boilers, smaller ships use fewer oil-fired boilers, according to the size of the tonnage can use four-shaft propulsion, three-shaft propulsion, two-shaft propulsion and even single-shaft propulsion.

At present, when China is carrying out the research and development of new equipment technology, it has paid great attention to generalization, because now the research and development of new equipment technology is costing more and more money, and the time required is getting longer and longer, and it is impossible to say that a subsystem is developed separately for a kind of equipment. For example, the army has carried out a series of plans such as the generalization of the chassis and the generalization of gasoline engines for the tanks used in the army, and the same is true for the navy, which tries to make the subsystems on warships at all levels universal.

In addition to the three major items of naval guns, protection, and power, the Department of Naval Administration has also boldly adopted many new technologies and equipment, and plans to provide the latest fire control computers for the new naval guns, and is preparing to carry radar equipment that is still under research on the BB-08.

China's shipboard main gun fire control computer has also developed quite rapidly, and after entering the 30s, the third generation of fire control computer has been launched, which is not only ready to be mounted on the BB-08, but also to upgrade the fire control system of many existing battleships.

As for the radar equipment, since it is still being studied, there is only one laboratory sample now, and according to the expectations of those technicians, it will be put into use in the next two to three years, and it will be equipped with the BB-08 at that time, and if it can work well, then it will also be equipped on a large scale on other existing warships.

The design of the BB-08 battleship can look very high, but to achieve such a high surname, the technical requirements are very strict, new naval guns, new power systems, new fire control systems, radar systems all need to invest a lot of money in research and development, not to mention the risk of research and development of these new technologies, even if the research and development is smooth, then it will cost a lot of money.

In order to be able to build the BB-08 battleship, the Admiralty allocated a special fund of up to 65 million, which is enough to build two heavy cruisers with a balanced surname, and can build a 20,000-ton treaty aircraft carrier with a scale of one and a half.

After the design plan was determined, the construction of BB-08 started quickly, and it was expected that the construction would officially start in January 1932, and it was expected that the entire construction period would reach about four years, and it would be completed and launched in 1936, and it would take about a year of outfitting and sea trials after launching, and it was expected that it would be able to enter the navy service in full condition in 1937.

After the design was finalized, the ship was given the official name, and like the four existing Chinese battleships, the BB-08 was named after the ancient emperors of China, hence the BB-08 name: Shaohao.

In the second half of 1931, the Chinese Navy entered a period of expansion of a new scale, not only pursuing the number of capital ships, but also the quantity and quality of auxiliary ships.
