With the long wave surveillance radar, the long wave can move forward around the surface of the earth and is not affected by the curved surface of the earth. However, the detection accuracy is poor and it can only determine the approximate position and distance of the enemy ship. Its only function is to predict the surveillance technology.
Mature, when used together with microwave radar, the latter's limitation in the earth's curved surface is compensated, and its value in seaplane detection is even smaller.
As for seaplanes carrying bombs to carry out bombing missions, that is even less reliable. One flight consumes a lot of fuel, but it cannot carry many bombs. Moreover, with the snail-like speed of seaplanes, the enemy only needs some air defense capabilities.
It can be easily shot down. It is far more convenient and cost-effective than using naval guns directly. It should be noted that the Chinese Navy is not like the Japanese Navy, which faces opponents such as squadrons that lack air defense capabilities. Therefore, seaplanes have a wider attack range than naval guns.
Became an advantage...
Seaplanes are good for anti-submarine warfare, and objectively they are of considerable value. However, relying solely on the 6 waterborne reconnaissance aircraft carried on two heavy cruisers will have limited effect. And if there are specialized anti-submarine ships accompanying them, then
There is no need to let two ships patrol again
I took the risk of carrying a seaplane, because the tonnage requirements of seaplanes for carrying ships are not much higher than those of later ship-based helicopters. Warships of two to three thousand tons or even smaller can carry them, and even if a medium-sized ship is bombed, the loss will be greater than the lifting weight.
Xunlai is definitely much smaller.
When it comes to helicopters, Hu Weidong naturally understands its value, but the manpower is limited. The technical difficulty is not small. The key is that it is difficult to mass produce and ensure reliability. For the time being, he can only focus on introducing ready-made technology from Germany. Although Germany during World War II
The helicopter has not been used on the battlefield, but most of the technical difficulties have been overcome. It is much more cost-effective to improve on this basis than to study it from scratch...
The space vacated after the seaplanes and missile launchers were removed was replaced by six anti-submarine depth bomb launchers to ensure that even if the Zhiyuan-class heavy cruiser operates alone, China has no overseas base. Once the heavy cruiser enters the ocean, the only destroyer whose endurance cannot keep up is
A burden. But there is enough to protect oneself.
The anti-submarine capability sonar is installed in the bulbous bow structure of the ship. This is also a major advantage. Not only is the effect better, but the speed does not decrease but increases. Two of them are 12-tube rocket deep bomb launchers, used for attacking larger
The four submarines in the distance are ordinary anti-submarine depth bomb launchers, used for attacking
Attack the enemy submarine approaching your own ship. Although these depth bombs may detonate after being attacked by the enemy, the use of acoustic proximity fuzes greatly improves the anti-submarine efficiency of the depth bombs, and the amount of charge is greatly reduced. Generally,
Just twenty or thirty kilograms. Anyway, there were no nuclear weapons during World War II.
With the help of proximity fuses, a big thing like a submarine has sufficient lethality. Even if it is detonated by an enemy attack, the power is not enough to penetrate the reinforced horizontal deck of the Zhiyuan-class heavy cruiser. The threat is far greater than that of seaplanes and missiles.
The gunpowder and its powder magazine were much smaller ...
The torpedo tubes have long been removed, and the weight of the six anti-submarine depth bomb launchers is smaller than that of three seaplanes and related facilities. In addition, some unnecessary loads inside the warships have been gradually cleared, and the dead weight of the two heavy cruisers
have been reduced, and the battery life has also been improved. For China, which has no overseas base, this is undoubtedly of special value...
After more than half a year of repairs and modifications, the overall performance of the Zhiyuan has been greatly improved. Together with its sister ship Jingyuan, which also underwent modifications, it became the top heavy cruiser in the world at that time. It is worth mentioning that the two
Although the main guns of each warship were successively reduced to the 203mml52 naval gun that the border area could completely produce independently at that time, no matter it was she speed, Jin
Both the g-speed and the barrel life are better than the previous maximum range of 40 kilometers, the firing speed is 10 rounds per minute, and the barrel life has reached more than 1,000 rounds... If coupled with the new artillery shell designed by Hu Weidong,
Even if there are only a few battlecruisers in the world now, they may not be their opponents. The performance parameters of the finally completed Zhiyuan-class heavy cruiser are as follows:
Displacement: 11,74,216,580 tons
Main dimensions: total length, width, meters and draft
Protection: 105 mm on the side, 80 mm on the deck, 80 mm on the front of the main turret, 30 mm on the remaining parts, and 120 mm on the command tower.
It is worth mentioning that according to Hu Weidong's original idea, the main combat method of the Zhiyuan-class heavy cruiser is to pursue enemy ships and counterattack when escaping. Therefore, as long as the defense of the ship's stern is strong enough, the armor on the side does not make much sense.
, even if they are not all removed, they should be greatly reduced to reduce the weight of the warship. However, such modifications have greatly affected the stability of the warship...
Later, under the advice of German experts, Hu Weidong had to accept a new plan in which the side armor was only 40mm thinner. However, because of this, the Zhiyuan-class heavy cruiser became more flexible in combat mode. The armor thickness of the main turret and deck was only 40mm.
The increase to 80 mm was also based on the same reason. Hu Weidong originally wanted to change the turret to a triple mount, but firstly, the technology did not exist at the time, and secondly, he was worried that it would affect the stability of the warship, so he still used it.
The original twin-mounted main turret., but even so, the warship's defensive capabilities have made a qualitative leap compared to before, especially the reinforced horizontal armor, which can completely resist the bombing of any dive bomber in the world. As for the horizontal
The bombers and torpedo bombers first passed the Zhiyuan class, which had a total of 132 anti-aircraft guns, and was assisted by a super-strong air defense fire network composed of gun sight radar, gyro sights and proximity fuzes...
Among them, the performance of the 127mm anti-aircraft gun and the 88mm anti-aircraft gun surpassed any anti-aircraft gun of the same caliber during World War II. The former had a maximum height of 15,000 meters, and the latter also had a range of 12,000 meters, and the fire speed was even more astonishing.
former
It is one shot every 4 seconds, and the latter has even reached the terrifying speed of one shot every 2 seconds. Since the transistor has eliminated the electron tube used in the original radio proximity fuze, the size of the fuze has been greatly reduced, so the charge of the anti-aircraft shell is naturally
It increases accordingly, and the power further increases.
