Chapter 279: Radar Defects

Although the devil was worried that the Chinese Navy would use a torpedo sneak attack at night to lay a lightning net around the warship, he never expected that the Chinese Navy would dare to take the captured heavy cruiser (Dingyuan could not appear too early, so as not to directly force the two giant ships of the devil out, then this trip would be equivalent to running in vain, so he temporarily stayed in the open sea and waited for the telegram of the Zhiyuan. ,!) drove to Weihaiwei to provoke, so when the Weihaiwei Harbor suddenly splashed a column of water that soared into the sky, many devils were really taken aback, and immediately exploded after reacting, the Chinese dared to challenge them at sea, don't they want to live?

The accuracy of naval guns at long distances is very low, in addition to the increase in the dispersion of shells after the distance is extended, the main reason is that the warship is a moving target, and the warship itself is also moving, of which the former has a particularly great impact. Based on the calculation of the speed of a warship at 20 or 30 knots or even faster, an enemy ship can move as many as 1,000 kilometers before a shell fired from a distance of several tens of kilometers flies to the target, and if the officers and men on board have experience, the route of its march is difficult to predict, and this will naturally cause the hit rate of the ship's guns to drop by a large margin. However, if it is an artillery attack on a fixed target, even at the maximum range of 50 kilometers, the dispersion radius of the 240 shells of the Zhiyuan main gun is around 100 meters, and even the smallest destroyer has a hit rate of more than 10 percent, not to mention that Sa Shijun asked the gunner to pick a big fight outside the two giant ships? As a result, the second shot hit the target, penetrating the main turret of the heavy cruiser, whose boilers had not yet been heated

It must be noted that under normal circumstances, it is due to the close proximity. The ballistics of naval guns are generally relatively straight, and the armor of the main turrets of Japanese heavy cruisers is almost as thin as nothing, and often the armor-piercing shells will directly penetrate out before exploding after being hit, and it is not easy to cause substantial damage to the hull. However, the shelling was carried out at the maximum range, so the elevation angle of the main gun reached 45 degrees, and the inclination angle of the shell when it fell was naturally just as large. As a result, instead of penetrating out, it went directly into the ammunition depot under the turret, causing a large explosion that sounded for dozens of miles. The ship was blown open at that time. What's even worse is that because the distance is too far, Sa Shijun is afraid of missing the opportunity to hit a fixed target. Even the procedure of correcting the first shell was omitted, and the rest of the front main guns were fired in turn immediately after the first shot, and because it was radar guidance rather than optical observation, it was impossible to see how many injuries the ship had suffered before it sank

The target finally disappeared from the radar screen, and Sa Shi Juncai confirmed that the ship had been sunk, but in addition to his excitement, he also realized the flaw in the radar guidance. It was decided to send a telegram to Qingdao to request the assistance of reconnaissance planes, otherwise every enemy ship would have to be completely sunk before stopping the shelling, which would be a waste of the life of the shells and barrels. Hu Weidong had never fought a naval battle, and Shen Honglie did not know enough about the new equipment of radar

Although the enemy could not be seen, the veterans in the fleet could estimate the caliber and type of artillery and the approximate location of the enemy ships as soon as they heard the sound of the falling shells, so soon the warships in the port rushed out at full speed. The few remaining water reconnaissance planes (Note 1) of the devils were also dispatched to search for traces of the enemy

Seeing the enemy's water reconnaissance plane from a distance, Sa Shijun's heart suddenly moved, and a thought was born, "Although it is safe to fire at a distance of forty or fifty kilometers, the hit rate is really too poor, and it can also sneak attack the warship parked in the harbor, once the enemy ship starts, it will almost be impossible to hit, even if the shell is not valuable, the life of the barrel of this main gun cannot withstand such a waste, the 240 mm caliber long barrel China has not yet been able to build, every time a barrel is broken, there is one less main gun." However, if you look at it visually, no matter how far it can shoot, naval guns can only aim at targets within 20 kilometers and fire, and if you want to shell warships farther away, you can only rely on airplanes (or balloons) to provide observation data, and if you call our planes to knock out the enemy's maritime reconnaissance planes."

Thinking of this, Sa Shijun immediately sent a report to Qingdao again, telling his thoughts to the former enemy command in the first theater, and at this time, the Zhiyuan had already turned around and moved away from Weihaiwei at maximum speed under his command, but its four 240-caliber rear main guns were aimed at an enemy heavy cruiser and began to shell the enemy ships in turn, although the pitiful hit rate was not much different from the blind

Seeing that the enemy was about to flee, the Japanese army refused to give up, and pursued more and more desperately, because the speed of the Japanese ships was very different, and the distance between them gradually increased, the originally huge fleet was quickly divided into three echelons, destroyers and cruisers rushed to the front, the two Nagato-class battleships were dragging behind, and the faster battleship Kirishima was alone in the middle of the two teams, on the one hand, it could not catch up with the warships in front, and on the other hand, it was separated from the two giant ships behind

Sa Shijun originally thought that the maximum range of the 240 main guns on his ship exceeding 50 kilometers was already very exaggerated, but he didn't expect that a high column of water suddenly splashed on the sea less than a thousand meters away from the Zhiyuan, Sa Shijun couldn't help but be surprised, "Are there also warships equipped with long-range naval guns in this wave of enemies?" ”

Although Sa Shijun did not know that this was the only ship of the same class on the Zhiyuan, the "Chikumo", the main gun in front of the heavy cruiser, but he also guessed that the enemy ship was not inferior to the ship, and he couldn't help frowning, although the Chinese Navy has always wanted to attack the Japanese invaders to take revenge, but as long as a little sane people know that the average quality of the officers and men of the Chinese Navy is very far behind the first-class Japanese Navy, not to mention that most of the Third Fleet are new recruits, and if it is a warship of the same grade, it is almost certain to be defeated. At this time, there was no choice but to send a report to the Dingyuan for help, but it was Qingdao's plane that arrived at the battlefield first

Note 1: In the previous air raids, many brave Japanese pilots took off with water reconnaissance planes to meet them, but all of them were shot down. However, many of those that did not take off were destroyed by enemy planes on catapults, causing explosions, directly injuring or even sinking the warships where they were located, and strictly speaking, the losses were even greater. In the final analysis, the devil can only be blamed for the wrong design of the catapult of the seaplane, and it is not ...... to let those pilots fly, and it is not not to fly)
