"Oahu, Hawaii, I'll be back someday. Pen? Interesting? Pavilion wWw. ｂiquge。 "Admiral Hasben Kimmel turned back to Oahu in the night before boarding the U.S. submarine.

It's a pity that his oath was not fulfilled in the end. Admiral Hasben Kimmel had intended to escape back to the United States in a submarine. However, submarines in this era are not able to dive underwater for a long time. More precisely, it's just a boat that can dive. Most of the time, he still sails on the water, and only dives when he encounters danger.

Therefore, the bow of submarines in this era is often sharp and blade-shaped, so as to be able to break through the waves and increase speed when sailing on the water. The speed on the surface of the water can often reach more than a dozen knots, but the speed under the water is only a few knots, and the speed is very slow.

This is very different from the submarines of later generations. Later submarines tended to dive for longer and faster speeds.

After leaving Oahu, the U.S. submarine intended to cross the strait between Oahu and Molokai into the waters east of the Hawaiian Islands, from where it would return to the west coast of the United States. It's just that I didn't expect this to be a road to death at all.

While the Chinese Navy is building an aircraft carrier force on a large scale, it has also strengthened the construction of relevant supporting warships. On the one hand, it is necessary to equip the aircraft carrier with specialized large air defense cruisers, which act as the personal bodyguard of the aircraft carrier. On the other hand, it is necessary to build large destroyers with both air defense and anti-submarine protection. While providing air defense capabilities for the aircraft carrier, it is also capable of attacking underwater targets, providing the aircraft carrier with a trinity of protection. As a result, in every aircraft carrier strike group of the Imperial Navy, there are two of the most advanced large destroyers.

The Imperial Navy's 1st and 2nd Carrier Strike Groups, each of which has two 'Non-class' destroyers, are the first large destroyers built by the Imperial Navy.

With a displacement of 3,000 tons, the destroyers of the 'Ren-class' are larger than the light cruisers of many countries, with a maximum speed of 37 knots and a twin-mounted 120-mm high-level dual-purpose gun, which can not only attack sea targets, but also defend against air. In addition, the ship had six 88-mm anti-aircraft guns, six twin 40-mm anti-aircraft guns and 10 quadruple 20-mm anti-aircraft guns. Coupled with 16 12.7 mm anti-aircraft machine guns, such anti-aircraft fire can be called perverted. If carrier-based aircraft want to attack such a battleship and sink it, the price to pay is definitely not small. At the same time, the ship is also equipped with the latest sonar system, which can effectively detect underwater targets. Then attack with depth charges or anti-submarine rockets. Once locked on by the ship's sonar, it is often difficult for enemy submarines to escape. In addition, the huge displacement allows this type of warship to carry more electronic equipment, including air search radar, sea search radar, gun sighting radar, anti-aircraft gun guidance radar, etc. These electronic equipment have further improved the combat performance of this type of warship. Perhaps, in terms of operations against sea surface targets, there are still some shortcomings. However, there is a huge advantage in the attack on air and underwater targets. This is undoubtedly very good for warships that accompany aircraft carrier operations. After all, the carrier-based aircraft of the aircraft carrier pose a huge threat to sea surface targets, and as long as the aircraft carrier is provided with air defense and anti-submarine, the safety of the aircraft carrier can be guaranteed, so that the aircraft carrier's fighters can be better displayed.

When Admiral Hasben Kimmel and others left Oahu on a U.S. submarine, there happened to be a 'Non-class' submarine moving nearby. This is the destroyer Mizu-san, which is part of the Imperial Navy's 2nd Carrier Strike Group.

In the sonar cabin of the destroyer Rensan, the sonar soldier was listening intently to the underwater sounds, and he needed to distinguish from the noisy underwater sounds the sound of a large torpedo swimming by, the sound of the waves, and the sound of a propeller. This is used to detect enemy submarines so that they can detect threats and launch attacks.

Suddenly, the sonar soldier frowned, and from the sonar, he accurately heard a very obvious noise, this noise was not a natural noise, it was definitely the noise emitted by mechanical equipment.

"Sir, two to three kilometers northeast, a suspicious target has been spotted." The sonar soldier reported.

"Keep a close watch, I'll report to the captain immediately." said the officer in charge of the sonar system.

When the captain of the destroyer Mizo learned of this, he immediately ordered the battleship to turn and approach the suspicious target to further confirm the identity of the target, and if it was an enemy submarine, they would immediately attack. After all, the aircraft carrier "Altai Mountains" of the Imperial Navy was operating not far away. Once approached by the submarines of the Americans, this is undoubtedly a huge threat.

The destroyer was approaching the target quickly, and as the distance got closer, the sonar crew was able to hear the target more clearly.

"Sir, you can confirm that one submarine." The sonar soldier said with great certainty.

"Is there any activity of our submarines nearby?" The captain asked.

"Sir, at this time, there are no submarines operating in this area of the Imperial Navy." A staff officer reported.

"That's the American submarine. The anti-submarine rocket is prepared, after which the location of the target is determined. The captain ordered.

Meanwhile, inside the U.S. submarine, Admiral Hasben Kimmel is resting in a cramped hammock. He was the commander of the Pacific Fleet, an admiral, and after he got on the submarine, the captain naturally had to give up his cabin.

However, perhaps because of the hot and humid environment inside the submarine, Admiral Hasben Kimmel was a little uneasy, as if something was going to happen.

"Get the captain." Admiral Hasben Kimmel ordered.

Two minutes later, the captain was in the cabin.

"Your Excellency, Commander, Klaus reports to you." The captain saluted.

"Well, Captain Krauss, when will we be able to get away from Oahu? I always felt that this sea was too dangerous. Admiral Hasben Kimmel said.

"Your Excellency, this sea area is full of Chinese warship activities, and it is indeed very dangerous. However, we need to sail for a few hours, get out of the area, and then go up to the surface and sail as fast as we can. It is expected that we will be able to barely get out of the danger zone by dawn tomorrow. When the time comes, we will only need to pay attention to the planes in the sky. On the submarine, a small anti-air search radar was deployed, and we were able to dive before being discovered by Chinese aircraft. So, in general, we won't be in much danger. The captain reported.

Admiral Hasben Kimmel nodded, and the captain's explanation dissipated a lot of his worries.

"Boom! Boom! Boom! ”

Suddenly, there was a sinking sound from outside the submarine, which was the sound of the water pressure causing the water to hit the submarine's pressure-resistant hull. At the same time, the submarine also shook.

Admiral Hasben Kimmel immediately turned pale, as the acting commander of the Pacific Fleet, an old navy, naturally knew that once the submarine was sunk, it was extremely unlikely that it would survive.

"What's going on? Have we been attacked? Will we be sunk? Admiral Hasben Kimmel asked, horrified.

"Your Excellency, the situation is not clear at this time, I need to return to the command position, and I assure you that I will do my best to escort you back to the United States." The captain saluted and walked away.

"What's going on? Have we been discovered by the Chinese? The captain asked aloud.

"I think so, Captain. The explosion just now was supposed to be the sound of a depth charge, but the power was a little less. The sonar chief reported.

"Hell, slow down, be quiet, and dive another ten meters." The captain commanded.

It's just that it's still a bit naïve to want to evade the interception of the Imperial Navy's most advanced sonar system in this way. Previously, the Imperial Navy's 'Ren-san' launched anti-submarine rockets into the waters where the US submarine was located, in order to further confirm the location of the US submarine. When the anti-submarine rocket explodes, the underwater pressure changes, and the current hits the submarine, making a sound, so that the sonar crew can provide a clearer target.

After discovering the target, the destroyer 'Ren-san' sailed further towards the waters where the target was located.

Inside the US submarine, the sound of propellers was heard overhead, and many US submariners had serious faces, and beads of sweat appeared on the foreheads of the group. And those senior US Navy officers who took the submarine were even more panicked in their eyes.

"Prepare for depth charges, set at a depth of fifty meters." The captain of the destroyer Mitsu-3 gave the order to attack.

Soon, several depth charges were dropped, exploding fifty meters underwater. The power gram of depth charges is not comparable to anti-submarine rockets, and it seems to fly calmly on the water, but the world has been turned upside down under the water. The water pressure generated by the explosion of the depth charge caused the impact of the submarine to shake constantly, and the people inside could not even stand on their feet. At the same time, the hull of the submarine was "crunched" by strong water pressure, as if it was about to be squeezed. In some places, water leaks have even begun.

"Oh God! Are we going to be sunk? The thought crossed the mind of Admiral Hasben Guimmel .

"Prepare for depth charges, set at a depth of sixty-five meters." The destroyer 'Rensan' attacked again.

Several depth charges were again dropped into the water and exploded sixty-five meters underwater. This round of explosions directly killed the American submarine.

It didn't take long for a layer of oil and splinters of wood and rags to float on the surface of the sea. This means that the American submarine has been sunk and sunk to the bottom of the sea as an iron coffin. Admiral Hasben Kimmel and others were buried in the deep sea (to be continued). )
