The captain of the Lu-35, Captain Omori Shaosa, also discovered the "Ziqiang", and immediately put away the periscope while giving an order: "Emergency dive!" Silent snorkeling! Dive five degrees! ”

Lu-35 began to desperately flee to the deep sea at full speed. There was silence in the submarine's cabin, the hands of the depth gauge spun like crazy, and the hull "crunched" as the water pressure increased after the dive. The submariners all held their breath and waited for the sound of explosions on the sea, the air inside the boat was tense and suffocating, and everyone's faces were filled with unease and fear, because they knew that this was an enemy harbor, and at least a dozen destroyers were moored, and that being discovered here would mean that the Lu-35 would be rounded up by enemy destroyers.

The Lu-35 dived to a depth of 70 meters in one go, and then turned off the engine under the order of Omori Shaosa and waited quietly.

Because judging by common sense, if a submarine wants to escape under the pursuit of a group of destroyers, the possibility is too small, because the submarine is too slow underwater, and it can reach a speed of 20 knots on the water, and only about 7.7 knots underwater, which is tantamount to a tortoise and hare race compared with the destroyers of the United States that have a speed of more than 30 knots at every turn.

Of course, the submarine is underwater, and the destroyer on the surface of the sea does not see the submarine.

But the problem is that the destroyers are all equipped with anti-submarine sonar...... Omori Shaosa is very clear that the active sonar of the American ghost animal still has many defects, but the passive sonar is more advanced, so if the submarine is diving underwater, the sound made by its propeller can easily be received by the destroyer of the American ghost animal and be besieged.

Because of these considerations, Omori decided to hide under the sea instead of fleeing.

Omori was right, and even sensible, that any submarine commander with combat experience would make the same decision in such a situation.

But what Omori didn't know was that if he ordered the submarine to escape desperately, it was very likely that he would really let him escape.

The reason is very simple, although there are many destroyers in Rabaul, most of them are destroyers of the Chinese Navy, and at this time they are still training, and even the "Ziqiang" has only just learned the basic operations.

In this regard, Colonel White did not order all the destroyers to round up the Japanese submarine, because he knew that doing so would likely cause confusion, especially since he had contacted headquarters and learned that there happened to be an American submarine near Rabaul...... It would be nice if those who had just learned to use their equipment for the Chinese Navy to blow up the sea with depth charges, or to hunt down U.S. Navy submarines as if they were Japanese submarines.

Therefore, White only ordered the "Datong" to assist the "Ziqiang" in the search, and the rest of the destroyers were all in front of the "Pinghai" aircraft carrier, and were ready for combat to search the nearby waters...... Although White knew that it was unlikely that the Japanese submarines would attack the "Hirakai" at this time, it was always good to be careful.

Zhang Chi agreed with White's series of orders, which also showed that White was an experienced officer who would remain calm in case of trouble. In fact, White is indeed the deputy captain of a U.S. Navy submarine not long ago, and he had to take a back seat because of a heart attack, that is, to command the destroyer "Clemson" to escort merchant ships.

It is precisely because White used to be a submariner and had rich experience in submarine warfare that he was also very good at anti-submarine warfare.

However, at this time, White had a miscalculation, he thought that the Japanese submarine would choose to escape.

Colonel White and Shosa Omori were both experienced commanders, but on this point they made diametrically opposed judgments...... This is not surprising, because Omori did not know about Rabaul's situation, and he thought that Rabaul's destroyers were experienced and combat-ready, while White knew that this was not the case.

So White ordered the "Ziqiang" and "Datong" to search and pursue the "absconding" Japanese submarine in two directions, but the result was obvious, they could not find it, because the Japanese submarine was parked not far from the same place.

The Japanese submarines could be regarded as enduring, and the sonar soldiers listened in horror as the destroyer drove over their heads, and the sensitivity became higher and higher (the sensitivity refers to the sound wave condition of the enemy sonar, the closer to the enemy ship, the higher the sensitivity, the lowest 1 degree, the highest 5 degrees), they thought that there would be depth charges dropped, but nothing happened, and the quiet and surprising underwater world made the Japanese sailors who had been prepared for depth charges shudder.

As the sensitivity of the sonar became lower and lower, Omori couldn't help but breathe a sigh of relief, because he knew that this meant that the destroyers of the American ghost beasts did not detect it.

But then Omori found himself in an awkward situation...... Although the enemy destroyer did not detect it, it could not escape. Because he was not sure if there were enemy destroyers nearby, and if there were destroyers nearby and he hastily launched submarines, the noise of the propeller would expose him to the enemy's guns.

Therefore, Omori can only wait, wait for the American ghost animals to be exhausted until they finally give up, and then they can sneak away.

Half an hour later, White was on the verge of giving up.

Because White knew very well that the speed of the submarine under water was very slow, if it had not caught up and searched for the target by this time...... That means you're going in the wrong direction. On the other hand, as time goes by, the possible orientation of the submarine, that is, the sea area that the destroyer will search, will become larger and larger, and two destroyers will not be enough.

"Fuck it!" White scolded: "This should be the best training for the Chinese Navy!" ”

"Let it run, huh?" Zhang Chi asked.

"Yes!" White replied: "It's a good fortune, it can go back alive, just because we don't train enough, if it comes half a month late, the situation will be completely different!" ”

After a pause, Zhang Chi said, "Why don't we go back to the same place and search again?" ”

"You mean ......"

"I think it's still in place!" Zhang Chi replied: "Of course, this is only possible!" ”

Zhang Chi didn't dare to hold out too much hope, after all, he was not an expert in this area, and he really couldn't talk about searching for submarines, there was sea water everywhere in front of him, and he couldn't see any difference at all, and the submarine could be hiding anywhere below.

But Zhang Chi had a feeling, whether it was a sixth sense or something else, that Zhang Chi just felt that the Japanese submarine was always behind him.
