Super military empire

The shipyard is not much to watch. After all, the installation of various equipment has not yet begun, and many of the equipment of the battleship parked on the sea has not been disassembled. A huge gantry crane is needed. Hang down.

Liu Yijiu did not go up to see the Iowa-class battleship that had been dismantled, but only looked at the two steel behemoths that made the world tremble from a distance on the embankment at the end of the dock, and then took him with him. Everyone returned to the technical meeting room of the Northern Shipyard.

Because the battleship is too large, the Chinese side is not familiar with the structure or other layouts. Now the renovation design team has placed the office directly in the North Shipyard. The surveying and mapping work has been completed long ago, and even the preliminary plan for the renovation has been completed. Determined.

In the huge technical meeting room, there is a two-meter-long model made according to 100:1 on the table in the middle. Many parts are even cut apart. The meeting room is surrounded by blackboards, some of which are on the top. The technical list of key parts is listed, and some blackboards are the assembly drawings of some places, so that people can understand the details of the renovation project at a glance.

"The biggest problem with the current retrofit design is the cancellation of the front and rear main guns. Nuclear power is adopted. The front and rear chimneys and other parts also need to be canceled. As a result, the center of the entire battleship will be shifted. If the bridge part is not moved It is difficult to achieve the center of gravity balance. This is the biggest difficulty we encountered in the overall design.” Seeing Liu Yijiu stopping in front of the model, Wu Tianhai introduced the situation to Liu Yijiu.

Having dealt with this young director several times, they knew that Liu Yijiu did not like to hear their reports, but wanted to hear about the difficulties encountered and the solutions to them.

When the Americans provided the battleship to the Chinese battleship Iowa, they cancelled the main guns and removed all the 8 heavy oil boilers inside. Only four steam boilers remained. Although the battleship was barely usable, it was because The center of gravity has changed and it cannot be used for war at all.

It must be reformed.

Liu Yijiu frowned when he looked at the model in front of him.

There have been many plans for the later generations of the magic reform Iowa class, but they have not considered the problem of shifting the center of gravity at all. After all, those who come up with the magic reform plan are not professional ship designers, or even they are not professional ship designers. Will not consider balance.

"Now if you demolish the chimney and other superstructures, the center of gravity will be higher, right?" Liu Yijiu looked at the model in front of him and asked Wu Tianhai.

The latter nodded, "The position of the bridge was originally relatively forward, because there were two triple-mounted main guns in the front. Once removed, the center of gravity began to move back. If the chimney next to the bridge and other superstructures are removed If it falls, the center of gravity will move forward again. Even the warship may roll over when maneuvering at a high speed..."

Wu Tianhai introduced the situation, especially after using the supercomputer in the technical room with several screens and the supercomputer provided by the Ninth Institute to show them after many demonstrations, Liu Yijiu also became a headache.

"This is currently the case. If a long-range early warning radar is installed on the bridge, although the weight will not increase much, the change in the center of gravity will be more obvious." Wang Kai also said on the side.

There have been obstacles in the structural design. After Liu Yijiu’s original transformation plan was simulated by a technical machine, the center of gravity changed very obviously. If it is a straight line, there is no problem. Once a turn occurs during a high-speed maneuver, This will have a catastrophic impact on the entire battleship.

"What if we equip more massive missiles on this? For example, each missile weighing 40 tons. In the original position of the main gun..." Dongfeng-31 missiles were equipped with battleships, not at the beginning. In the program.

"It's not good either. It's mainly these designs. The balance is considered at the beginning. As long as the bridge is not moved and the superstructure is removed, the stability will be improved by about three meters compared to the original. This is a very dangerous design!"

Wu Tianhai shook his head.

It doesn't really matter what missiles the battleship is equipped with.

Because the balance must be reached before these missiles are installed, otherwise they will become more dangerous when they are installed.

At that time, with such a long period of hard work, huge amounts of funds will be buried in the ocean.

"In that case, you can only dismantle the bridge?" If the bridge part is dismantled, the whole project is too much.

Almost all designers nodded.

Deng Jianjun has been studying the structural design and internal space layout of the Iowa-class battleship here, preparing for the design of the 10,000-ton-class 055 large guided missile destroyer they are starting.

It is not the Iowa-class battleships, almost all the huge battleships in the world appeared after countless technological accumulations. This accumulation is lacking in the Chinese naval equipment designers."Director Liu, or else, let's take it down and use the first-floor type of the Soviet Kirov-class guided-missile cruiser. The two-story first-floor design is adopted. The main firepower is concentrated on the front deck and the personnel live in the middle..."

The Soviet Kirov data, 701 obtained a lot, all of them were obtained by Liu Yijiu through the black guards for reference in the 701 design.

After all, Kirov is the most powerful guided-missile cruiser in the world.

With just four ships, it can compete with 20 American Ticonderoga-class guided missile destroyers.

"If so, except for the shell problem of the battleship, all buildings will change. How long will it take? We don't have much time to verify the design in this area!" Wu Tianhai shook his head. With such a plan, they I considered it at the beginning.

Through computer simulation, it is still impossible to solve these problems.

Moreover, the warship close to 300 meters long is much wider than Kirov. In order to maintain stability and the center of the entire warship, the bridge was originally placed forward, and a large number of detection equipment and secondary artillery were installed beside it, and the chimney behind It is leaning on the bridge.

The new transformation project using nuclear power and the advancement of electronic technology will reduce the weight of many equipment. After this transformation, the standard displacement of the entire warship will be reduced to less than 35,000 tons.This is nearly 10,000 tons less than the original design!

Such a challenge is actually much greater than the difficulty of designing new ones on the Chinese side.

"Not to mention other things. According to the overall situation of the warship, our missiles need to be arranged in front and rear. The main missile is also the largest deterrent in the future. It is about 13 to 14 meters in length and about two meters in diameter. More than forty tons...There are other types of anti-ship missiles, anti-aircraft missiles, anti-submarine missiles, torpedoes and other weapons and equipment...These are issues that you should consider when designing." Liu Yijiu had no choice.

He is not an expert in ship design.

"Even missiles of more than 40 tons will not work. Before that, the weight of a main gun was 1730 tons only by rotating part. We need about 43 such missiles to balance the original weight, even if some launching equipment is added. , At least 30 pieces are needed to balance the weight of a main gun..." Wu Tianhai's words caused Liu Yijiu's mouth to twitch.

Let’s not say whether this can be equipped with so many Dongfeng-31, even if it can be installed, a battleship can be equipped with a hundred Dongfeng-31, the Ninth People's Court must not go bankrupt?

Therefore, such a situation is simply impossible.

These issues were not considered at the beginning.

"What is your plan?" After so many years, it is impossible for 801 to not even come up with a solution.

Liu Yijiu needs to know the solution.

"Remove all the superstructures, determine the power cabin and internal structure inside, and then arrange the superstructure!" Wu Tianhai's solution can be said to be the most feasible.

The problem is that this amount of engineering is too large.

This seems to have no such precedent in the world of warship manufacturing.

The hull is manufactured first, and then the weapon system is installed.

Power or something, this is normal, but the bridge is originally part of the hull.

"If we follow this plan, how many years will it take to complete the transformation?" Liu Yijiu pondered for a long time before asking them.

"The transformation of the hull part can be completed in three years."

"What about the weapon system? This is a little different from the previous plan." Three years are still acceptable.

Weapon outfitting, especially various systems, are basically carried out in the process of ship hull transformation.

"I think that all the 20 secondary guns on both sides can be removed. The secondary guns with a range of more than ten kilometers will be of little use in future wars. We should change these 127mm secondary guns to a smaller caliber and rate of fire. Faster high-level dual-purpose guns to defend against threats from the air."

"The secondary artillery still needs to be kept. Sometimes it is useful to deal with some small fish and shrimps. However, it is best to change the caliber to the same model as the domestic one." Liu Yijiu could not agree to remove the secondary artillery. The cost of attacking with missiles is too high. The cost of shells is much lower than that of missiles. Moreover, in order to increase the firepower density, some number should be increased. This mainly considers small-caliber rapid-fire guns..."

Liu Yijiu pointed to some parts on the model of the warship.

Although the battleship has thick skin and thick skin, it is resistant to handling, and is not easy to be sunk, but it can defend against incoming missiles, which is much better than being hit and repaired.

Moreover, he wants to make this a hedgehog!

Whether it is offensive or defensive capabilities, it must make the whole world tremble.

Otherwise, sorry for the title of guided missile battleship.
