Project 172 submarine drove directly towards the target. The first 4 and the last 2 * are still loaded, and if you want to say that you don't shoot a single shot, you will get two results in vain, and Captain Callahan can't convince his conscience. Of course, the more important reason was that his co-captain reported that there were no guns on the enemy's large ships. He could barely believe his ears.

In the periscope, you can clearly see that there are also seaplanes taking off from the side of the ship. Obviously, it is a large ship, which is not in the identification manual, but the hull is that of a cruiser, so it can be seen that it is an important target. There were a lot of weird modifications on the hull, and he thought, what the hell are the Japanese doing here?

He observed that there were several seaplanes under and below the ship, and to some extent, the ship could not only be called a seaplane carrier, but also a transit station. Of course, he couldn't understand what the front and rear cranes were doing when they fell to the ground. Anyway, there was no cannon in sight, and the chimney of the ship was emitting green smoke, and it seemed that he had just prepared the car to run, which made him excited. Fortunately, I didn't dive, otherwise I would have wasted time by diving and floating, and maybe let the opponent run away at speed. The cruiser, of course, was much faster than the submarine, but it could not move yet.

On the Agano, the captain of the ship, Sanshiro Nakasa, Kikawa, was scolding his subordinates to hurry up the anchor and prepare the car, but in order for the warships of this era to set sail, they needed boiler heating and pipe pressurization, where was it so fast.

This morning, he was a little careless and kept the pressure to a minimum when he got off anchor. This new ship can only burn heavy oil, the navy cherishes oil has its tradition, especially Kikawa Nakasa was born in a poor family, when he was a child for the landlord's family to farm land, especially good at living, such a few days and nights of work on the sea, for him at any time to burn oil is really unbearable, so he decided to maintain the pressure to a minimum, now to die. In fact, just after receiving the news of the discovery of the submarine in front, he began to be anxious. But the message sent by 419 pretending to be a Japanese cargo ship was vague and gave the impression that the enemy submarine was heading in the direction of the Chinese coast, so between hesitations, he was a little late, and this short moment was obviously fatal. Two hours earlier, the situation had become serious and the Tide Breeze had left south before it began to prepare. Now he asks the boiler compartment every 5 minutes, and the reply is that the pressure is insufficient, and it will take time to start.

In fact, at this time, he still has 4 divers below, two are working, two are decompressing, as long as the hull moves, these four will definitely die, but he doesn't think about these, there are 20 divers on board as spare tires, the key is how to escape.

The drone of 419 saw that there was a seaplane taking off, and it seemed that there was an enemy who wanted to escape, but unfortunately there was no way. Even if 419 is launched *, it will not have time to destroy it all, and the position of 419 is 120 km behind the US submarine.

However, it seemed that the American captain was very energetic, and he saw that the enemy's speed could not get up for a while, and he was ready to go around to the side to seize a good position.

Agano forcibly starts under insufficient pressure. Obviously, the speed and rudder effect are difficult to show immediately, and the captain forcibly raised the diving bell hanging at a depth of 120 meters, and the people inside suddenly lost their water pressure without completely releasing the dissolved gases in their blood (this old diving bell did not have the ability to apply water pressure on its own), and they were bound to die of pain within a few days due to latent disease. The other empty diving bell was also raised, leaving the two still working below, who would die quietly at the bottom of the ocean after running out of oxygen.

Of course, within three days from the start of the ship's operation to the arrival of 419 from the South China Sea, 1.5 tons of things were still salvaged. According to Makino's arrangement, there are several seaplanes every day to transport the salvaged goods to Kagoshima in time. The attack on the ship was entirely expected by Makino, and he didn't need more facts to convince himself - there was a Chinese submarine ready to subvert his plans; What he has to do is to meet all the challenges with the best possible preparation.

American submarines arrived from 20 kilometers away, and the stupid Japanese cruisers only increased to 5 knots, and the speed was very slow. Callahan decided to shoot closely. He ordered to first shoot the two nasty twin 25mm guns on the cruiser with 76-mm guns and knock them out. There were two other anti-aircraft guns of the same model, and on the other side, he didn't care. At close range, the firepower of these small-caliber rapid-fire guns could still overwhelm the 76 guns, and the submarine pressurized shells posed a threat.

In this bizarre naval battle, the 3-inch main gun actually dominated the battlefield. Kikawa Nakasana called a hate, he has been trying to leave the modification plan left and right, originally said to keep a 127-mm gun with a firing range of 180 degrees in the stern, but when it came, in order to increase the seaplane shunting, it was also dismantled. He didn't know who the designer was, and if this person appeared in front of him, he would definitely kill him with his own hands.

The submarine, with a huge speed advantage of 10 knots from the side, overtook the cruiser and was in no hurry to turn around and shoot. Still maintain a distance of 1.5 nautical miles. The shooters on deck were in good spirits, they had just practiced for several hours in the pursuit of cargo ships, fired more than 200 shells, and had already learned how to shoot at the rocking hull. The gunner waited for the surge to push the submarine to its maximum, creating a period of calm to start firing. Forty or fifty rounds were fired, and a 25-mm gun in the rear was successfully destroyed. Many of the shells that did not hit were not in vain, and most of them fell on the hull of the ship, killing many people. If they can return safely, they will have an endless conversation for the rest of their lives: during the Pacific War, they operated a submarine with a displacement of 1,200 tons on the water, and engaged in artillery battles with a large ship of 7,000 tons.

The only seaplane in the sky swooped down in an attempt to drop several 25-kilogram small * threatening submarines. The two four-mounted machine guns on the Porpoise submarine were not given in vain, and they were not afraid to deal with low-speed reconnaissance planes. Captain Callahan also personally went to the hull to operate the boat to avoid the threat from the air. The variable course of the submarine thwarted all the bombs. The seaplane was thrown *, only the self-defense machine gun in the back seat remained, which was basically useless, and in the end, the Japanese pilot decided to commit suicide to ram. But his thin plane had been swept many times by a 7.62 mm machine gun. When he collided with the target, he was enveloped by a dense number of bullets, and finally broke the wing and fell behind the 172. Callahan turned his head and sneered, he knew that he was going to go down in history today. He ordered the left rudder to be 40 degrees and approached the target. It was hoped that the last twin 25-mm guns would be eliminated during the approach of the enemy ships.

The 76-mm guns on the foredeck lived up to expectations, and in the time they chased from 1.5 nautical miles to 1 nautical mile, they fired 40 guns in succession, destroying the anti-aircraft guns that stubbornly counterattacked. The surface team on SS172 paid the price of only one killed and three slightly injured. The Japanese 25-mm anti-aircraft guns, which used * loading shells and had a too slow rate of fire, were the crux of the failure of the confrontation.

The surface gunners reported that the shells had run out. In more than five hours, more than 300 shells were fired from this cannon, which may have set a world record in this world war. The captain gave the order to stop shooting, and the rest was left to himself. The bow of the No. 172 submarine is at an angle of 70 degrees to the target. The captain judged that the enemy could be at a speed of 8 knots, in which case there was not enough rudder effect to turn and dodge*, even if they could see the trail*. He ordered the minimum depth to be set so as not to slip through the keel without exploding.

On the Agano, Japanese sailors began to shoot at the submarine with rifles, of course, to no avail. Kikawa looked at the ruthless submarine with a telescope, and for a moment he looked at Captain Callaghan, who also had a telescope on his enclosure, and he saw the bearded American smiling at him. If there's a slightly decent cannon, why not? Knowing that the enemy was about to launch,* he ordered a lookout post to watch the sea, ready to turn at any moment.

Callahan, seeing that he was within a kilometer after all, ordered a salvo of 4 * shots. When *rushed out* of the pipe, the splash caused by the compressed air was discovered by the Japanese ship. What's more, they are very shallow, and you can almost see them dragging white splashes towards the Japanese warships. According to the distance, within a minute, you will be in front of you.

Kikawa immediately ordered a turn, but the lack of speed caused the warship to turn softly, not to mention that Makino's modification reduced the ship's navigation ability a lot.

The angle of fire of Karahanding was very small, and 4* rushed towards the target in a fan shape with a small arc. The two of them, one at one end and one at the tail, were turned and dodged by the Japanese ships, but the middle two were lucky. They hit the cruiser at an angle of 45 degrees, and if two months ago, at such an angle, there was only half a chance of triggering the fuse, but the improved * brought by this ship, although it still did not have the ability to detonate under the keel, but the trigger part was much more reliable. Two * exploded together, immediately tearing huge gaps under the hull.

Kikawa ordered the corresponding compartment to be closed immediately to avoid water entering too quickly. But what he was most worried about now was not the flooding, but the fact that one * hit the power part, and the speed of the warship began to drop.

The submarine No. 172 continued to move at high speed on the surface of the sea, watching the Japanese ship gradually stop. Apparently he did not have time to wait to see the sinking of the Japanese ship, or to reload the bow * again, he took up a perfect position, grabbed the head and began to make a U-turn. The submarine also has two * in the stern, and this time it will shoot at the side of a ship with a complete lack of speed at an angle of almost 90 degrees at a distance of 500 meters.

The Agano continued to drive for a while by virtue of inertia, and then stopped completely, and found itself parked on the side of the submarine, and the people had already aimed their butts at themselves.

Ji Chuan stood in the wheelhouse, looked at the submarine through a piece of cracked glass, gritted his teeth with hatred, and only said one word: "Mixi"

Then I watched the two* come towards me.

Captain Callahan was already on board with a camera and stood on the foredeck, shaking the 16mm camera to shoot.

Two huge explosions in quick succession quickly pronounced the death of the Japanese ship. Of course, that's not all. The cameras captured the last moments of the oddly shaped vessel, and there are bound to be some details that U.S. intelligence analysts need to think about carefully.
