A group of Japanese soldiers, standing on the sloping deck, raised the flag and saluted to the rising sun that had descended, one by one, and then jumped into the sea, and these Japanese soldiers jumped into the icy sea water one by one like dumplings, and the Ruihe was already approaching here, ready to salvage.

Under the Palau Ridge, a submarine stayed there tightly, and it was obvious that it had placed the torpedo just now.

"Hit, the target is sinking." The crew took their eyes off the periscope, the soldier said.

"Got it, get out of here and move on to your next target." The captain issued the order.

The tail fan blades of the submarine, which was quietly parked there, turned and pushed the submarine forward.

With a speed of 22 knots, he was a little faster than the Japanese fleet, and could reach the ambush site in advance.

The Japanese reacted quickly, and after the Xianghe was hit, they immediately began to search, where the torpedo was launched from, they agreed that it was launched by the submarine, so they asked people to find the location of the submarine, and the anti-submarine torpedoes on the destroyer pushed down the water one by one to blow up the fish.

The explosion blew up a large area of fish, and there was nothing about submarines except that fish were fish.

In normal times, they would definitely be very excited to see so many fish, but now they are not happy at all, a submarine under this water is a bomb for them, threatening the safety of their fleet at any time, and it is difficult for them to feel at ease if they do not get rid of it.

On the destroyer, the Japanese turned on the sonar, and the sonar detection effect of this period was only one to two nautical miles, and the passive detection range was a little longer, but it was not much longer. However, it is said that the German U-boat has an ultra-long detection range of 8 nautical miles, although the farther the distance, the more noise, the worse the effect, but the detection is so far, in one or two nautical miles, the efficiency is much stronger than that of other countries' sonar.

The Japanese Army's Type 94 Acoustic Instrument, with a detection distance of one or two nautical miles, was useless, and no trace of a submarine was detected at all.

Then there are only two reasons, one is that the other party has left here, or there is silence, and everything that can make a sound is turned off.

The first is that the Japanese speculated that after the submarine fired a torpedo at the Xianghe, it immediately dived and left here immediately, but when the submarine launched a torpedo attack, it was not too far from the battleship, and the speed was slow, so it should have been poked out, but the sonar did not find anything.

Then there is only the second possibility, silence, that is, to stay quietly in the water, turn off any instruments, especially the engines, and do not make any sound, so that the submarine does not make any noise and will not be detected.

At present, the Japanese army speculates that there is only a second chance, and the other side is silent somewhere in the sea.

In order to prevent being attacked again, the Japanese army adopted a simple method, that is, to spread out the formation, especially the destroyers, scattered far away, and the sonar was always on, so that the detection range was wide, which could effectively prevent submarine sneak attacks, of course, they could only defend against submarines of this era.

However, the Japanese army also has a hard time and can't say it, before the start of the fight, they lost a main aircraft carrier, and they don't know who the sneak attack was, needless to say, the most suspicious is the 41st Group Army, but do they have submarines? Maybe you can buy it, after all, they even have battleships, and submarines are not a trivial matter, and I heard that their relationship with Germany is not bad, and Germany's U-boats are very good. The Japanese can be considered to be using German submarines, after all, German submarines are really powerful.

Knowing that the 41st Group Army had submarines, they had to be cautious about the sudden appearance of torpedoes, and they also had to guard against other submarines ambushed by the 41st Army on the road.

Because the German submarines were only able to reach a speed of 6 knots underwater, he knew this, and their fleet was traveling at about 15 knots, so they did not think that the submarine that had ambushed them before would be able to catch up. Therefore, the Japanese thought that they wanted to ambush the fleet later, and they could believe that the 41st Army had only one submarine. Although they do not know exactly what the financial resources of the 41st Group Army are, it can be seen that when they are fighting, bullets and shells are fired at will, and what can be solved with artillery shells is never solved with rifles.

The Japanese soldiers no longer had the kind of laughter and slapstick that they had when they sailed out of the port at the beginning, and they all had serious expressions, staying at their posts and waiting for the battle.

"Commander, submarine No. 3 has just sent a telegram that they have met the Japanese fleet in the Palau Ridge and have sunk an aircraft carrier." Lu Qiang, who was standing in front of the map, listened to the report of his subordinates.

"I see, there's no problem with submarine three, right?" Lu Qiang nodded and asked.

"There is nothing wrong with it." Subordinate Dao.

"Well, you go down first." Lu Qiang waved his hand, and then continued to look at the map, in front of him was a huge world map, which occupied the entire wall, and the area of this wall was 4x6.

"Palau Ridge." Lu Qiang read silently, took a red chart and circled the Palau Ridge on the map, and then looked down along the Palau Ridge, and drew down the map, the West Caroline Basin, the East Melanesian Trench, through the Balmas Sea, the British Isles Strait, into the Coral Sea, and Brisbane is the Coral Sea to the east.

Or take the Palau Ridge, pass through the Philippine/Li/Bin Trench, the Malugu Strait, enter the Arafura Sea, and take the Torres Strait to enter the Coral Sea.

Of course, if the Japanese army wants to make a detour, it will be another matter, but with the current situation of the Japanese army's urgency, the detour is not very likely.

In order to ambush the Japanese submarines, he scattered ten submarines into the ocean, relying on the speed of 22 knots, he could also catch up with the Japanese fleet, and even seize the opportunity.

Ten submarines were scattered in the various seas of the South China Sea, waiting for the Japanese fleet to come to the door, and now Lu Qiang roughly judged the route of the Japanese army, so he decided to gather the submarines, 5 to the Balmais Sea, 5 to the Arafura Sea, so that the Japanese army could meet no matter which route they took.

However, if the Japanese army takes a whim and takes a detour, then Lu Qiang's plan will be bye, but Lu Qiang also wants to gamble, after all, the probability of winning his bet is quite large, even if he loses the bet, there is no big problem.

These submarines will also rush to the Coral Sea to attack Japanese submarines, but the Japanese planes are somewhat threatening to the 10 divisions currently in Brisbane, there is no air force, only anti-aircraft weapons, but blindly defending, will only make morale lower and lower. But there is no air force, then submarines play the role of an offensive here. (To be continued.) )
