readx; At 3:40 p.m. on 8 December, shortly after the first wave of Chinese Navy's carrier-based aircraft dropped bombs and retreated, the second wave of attack planes launched by four Chinese aircraft carriers began to arrive over the main fleet of the Navy. Pen & Fun & Pavilion www.biquge.info

Although the number of attack aircraft in the second wave of the Chinese Navy was slightly smaller than that of the first wave, it was also as high as more than 130 aircraft, and in the second wave of attack aircraft, a large number of torpedo bombers were concentrated.

Limited by the constraints of today's aviation technology, the speed of the aircraft in service in the navy and air force of various countries in this era is far from being as high as during World War II, among which the maximum speed of the latest cutting-edge F3 fighter in the Chinese Air Force is only 350 kilometers per hour, while a large number of F2 improved series fighters in service are only about 280 kilometers, and the speed of B6 dive bombers is slower, and the level flight speed is only 240 kilometers, even if it is equipped with a new engine of Shanghai Aviation Power Company. Its level flight speed has only increased to about 260 kilometers, and the speed of torpedo aircraft is even slower, and the first B5 torpedo bomber in service with the Chinese Navy has a speed of only 180 kilometers, and even after improvement, it is only about 200 kilometers.

Compared with the anti-aircraft fire on warships, the speed of aircraft in this era is still on the slow side. Although there was no essential gap in the air defense technology of warships in the thirties and twenties or even during the First World War, the only difference was that the density of anti-aircraft fire on warships increased in the later period, but this increase was not technical, but quantitative.

This can be seen from the improvement of the anti-aircraft firepower of the Yandi class in China, where the anti-aircraft firepower is only eight single-mounted three-inch anti-aircraft guns and twelve 12.7-mm anti-aircraft machine guns. In addition, the Yandi-class battleship also had ten twin seats, a total of twenty five-inch and forty-fold high-level dual-purpose guns. In the mid-twenties, anti-aircraft firepower was improved, and the three-inch and fifty-fold anti-aircraft guns, which were slightly less effective in anti-aircraft defense, were dismantled, and more 30-mm anti-aircraft guns were equipped. In fact, this modification did not only occur on the Yandi class, but also occurred in China's latest construction of the Shundi-class battleships and other heavy cruisers, 30-millimeter anti-aircraft guns entered the navy service in large numbers in the mid-to-late 20s, and the relative three-inch anti-aircraft guns began to be retired from the main warships, but they will not be thrown away, but will be moved to some important ports and fortresses on land to serve as the task of air defense in important places.

For example, the Americans have developed a five-inch, 38-fold high-level dual-purpose gun and a one-inch-inch rapid-fire anti-aircraft gun and equipped them with new warships, plus 12.7 mm anti-aircraft machine guns, forming an air defense network on the main warships. It's just that although these countries have all been modified, they definitely don't pay as much attention to as China.

He said, "Although I do not attach as much importance to air defense as China, I have learned a lesson after the first Sino-Chinese war, so I said: "The air defense force on the ships of this navy should not be underestimated."

In the twenties and even the mid-to-early thirties, the speed of combat aircraft did not achieve absolute superiority over warships, because increasing the speed of aircraft required a long process and had great technical limitations, and it was really easy to increase the anti-aircraft firepower on warships, and it was enough to directly increase the number of anti-aircraft guns, and there was no technological gap.

In this case, an attack by the air force on a warship requires a certain amount of tactics, which is the fundamental reason why the Chinese Navy attaches great importance to dive bombers. Because dive bombers can use dive attacks to destroy a large number of anti-aircraft guns and a large number of open-air equipment on enemy warships with high precision, it is only 250 kilograms of semi-armor-piercing aerial bombs carried by China's B6 dive bombs, which are sufficient to attack lightly armored targets, but they are still slightly insufficient to deal with battleships, and it is very difficult to sink enemy ships directly with semi-armor-piercing aerial bombs. It was necessary to rely on a large number of torpedo bombers for torpedo attacks.

And this is the reason why most of the dive bombers were concentrated in the first wave of attack aircraft, and these dive bombers needed to use the dive bombing mode in advance to clear the anti-aircraft fire on the fleet, so as to create opportunities for subsequent torpedo bombers to drop torpedoes.

Eisuke Yamamoto looked at the torpedo with white waves on the sea, his eyes were about to burst into flames, and there was another loud bang. Eisuke Yamamoto clearly saw that the four Chinese torpedo planes dropped four torpedoes at the same time, but these four torpedoes formed a fan of about 30 degrees towards the Nagato, although the Nagato dodged two of them, but this kind of fan torpedo attack is destined to be impossible to dodge all of them, so it didn't take long for a muffled sound to come from the port side of the Nagato, and then a water column tens of meters high rose from the port side, this water column has not completely fallen, and the middle of its port side was hit by a torpedo again.

The attack of these two torpedoes fatally wounded the Nagato, although the torpedoes did not cause the ammunition to explode or cause a fire of fuel, but the explosion of the two torpedoes left two huge gaps in the port side of the Nagato, and this was still a gap underwater, and almost instantly, a large amount of seawater poured into the Nagato.

At this time, the Nagato was bombed by several dive bombers, and soon another 250-kilogram aerial bomb hit its bridge, although it did not explode deep into the Nagato, but it blew up the upper bridge, and also caused a fire on the bridge, with few casualties, and also destroyed a large number of open-air equipment on the bridge.

Eisuke Yamamoto looked at the Nagato number in front of him worriedly: "How is the situation over there in Nakamura Daisa?" ”

The Nakamura Osano in his mouth is the captain of the Nagato, Nakamura Kamezaburo, who has just been transferred to the Nagato as the captain after the outbreak of the war, and it has only been a week now.

In fact, it is now said that "most of the officers in charge of this navy have just taken up their posts, and this is related to the time of large-scale transfers in this navy every year, and according to the practice of previous years, in peacetime, it is said that "the time for large-scale transfer of various departments of this navy is mainly concentrated in the time period from November to December, and in particular, December 1 is an extremely important time for transfers. As a result, the transfer of important departments was suspended, but the positions of colonels such as captains were transferred as usual.

It didn't take long for his subordinates to report: "Nakamura Osa is calling, the Nagato is still in combat power, he has ordered to fill the starboard side with water and maintain the balance of the Nagato, but the speed of the Nagato has been reduced to only twenty knots!" ”

It has to be said that it is not so easy to sink a battleship, so far, the Nagato has been hit by at least five 250 kg bombs, two torpedoes, in addition to a number of 50 kg bombs, but even if the Nagato is scarred, it is still not sunk, and even the vital compartment is fine, the ammunition depot, and the wheel room are still intact.

Eisuke Yamamoto heard this, but his face continued to be gloomy, although it was said that the Nagato did not sink, but no matter what, it was hit hard, the speed was reduced to only twenty knots, not to mention, and because a large number of observation and sighting equipment was destroyed, the combat effectiveness that could be exerted has been greatly reduced.

In this case, the Nagato could no longer continue to follow the pace of the main fleet, you must know that now Yamamoto Eisuke's fleet has adopted a wartime cruising state, the cruising speed of the entire fleet is as high as 23 knots, and it is impossible for the Nagato and several other warships to reduce their speed after being severely damaged.

After the Nagato was heavily damaged, China's second wave of attack planes continued to fly in the sky, and the dive bombers were looking for opportunities to dive down from a high altitude, and those torpedo planes directly lowered to an altitude of 100 meters and dropped torpedoes at a distance of about 1,000 to 1,500 meters from the enemy ship, and the torpedoes that were dropped were the 1926 aviation torpedoes that the Chinese Navy commissioned in 1926, which weighed only 500 kilograms unlike the 1920 aviation torpedo. The 1926 aviation torpedo benefited from the increased bomb load of the carrier-based torpedo at that time, so its weight was correspondingly increased to 800 kilograms, and this torpedo has replaced the early 1920 aviation torpedo with frequent failures and less powerful as the main active aviation torpedo of the Navy.

After the 1926 aircraft torpedo is placed on the surface, it first sinks to a depth of about 50 meters on the bottom of the sea, then rises to a depth of about 3 to 4 meters, and finally rushes to the target at a speed of up to 40 knots.

With a loud bang, Eisuke Yamamoto once again saw that the Amagi in the distance was also hit by a torpedo, and the Amagi, like the Nagato, was also attacked by many Chinese aircraft, and in just a few minutes, six dive bombers had launched an attack on him and dropped numerous bombs, followed by a torpedo.

Unlike Nagato's good fortune, the Amagi was somewhat unlucky, first the hit torpedo blew open a gap and caused a large amount of water, and then a 250 mm semi-armor-piercing projectile pierced the rear horizontal armor and exploded deep into the internal compartment, causing a fire, which quickly spread to the ammunition depot of the rear main gun. The high temperatures caused by the fire caused a chain explosion of ammunition in the ammunition depot.

What is the most feared thing about a warship? It was not the main guns that were destroyed, nor the torpedoes, nor the anti-aircraft gun emplacements in the open air that were destroyed, but the most feared thing was the detonation of the ammunition depot.

Once the ammunition depot is detonated, the fate of the warship, whether it is a small destroyer or a huge battleship, is extremely tragic.

After the Amagi's ammunition depot was detonated, the force of the explosion was greater than that of ten aviation torpedoes hitting it at the same time, and the huge explosion directly shattered the Amagi's internal compartment, although it did not disintegrate on the spot, but it instantly caused the Amagi to lose power and caused an even more violent fire.

Looking at the flames on the Amagi, Eisuke Yamamoto knew that this huge battleship was finished!
