Chief of Staff Ma Yanshu said: "In addition to the advantage of having a base, we also have an advantageous condition that although we are far away from the basin of Pacific Area A, we have a mountain range at the bottom for us to use, which can provide us with cover and ensure that we can enter and exit this basin out of nowhere."

This basin is a golden treasure for testing the performance of submarines, covering an area of about four million square kilometers. Due to the influence of the Pacific Ocean Seamounts, submarines in the Americas, especially nuclear submarines, have to go there if they want to go to Asia, otherwise they must go to the southernmost tip of South America and go around Australia to reach Asian waters, and other waterways are easy for them to discover by the opponent's antisubmarine equipment. We can find more opponents to train on here, to be able to battle wits with potential opponents.

According to the topography of the seabed that we have obtained, it is found that from here there is a trench with an average depth of 1,500 meters, up to that golden place, which is very suitable for our departure and withdrawal. The most valuable thing is that there are several special places along the way, which are especially suitable for us to escape from the enemy's tracking. Here's a chart of this one, everyone! Chief of Staff Ma said and walked towards the sea chart hanging on the wall.

At this time, Jiang Haitao stood up and motioned for everyone to come forward and take a look.

Ma Yanshu tore off the curtain covering most of the map covering the map, then grabbed a whip and pointed at a point on the map, and after a few people stood up, he continued: "This place is the center of the golden place I just mentioned, thirty degrees north latitude and one hundred and sixty-fifth degrees east longitude. With it as the center of the circle, with a radius of 800 nautical miles, the golden places are contained in it, and the island of Minami Bird in Japan and Hawaiwa Island in the United States are near here.

And from where we are, this is it. Ten degrees north latitude, one hundred and forty degrees east longitude, that is, the trench starts from us and extends northeast to the golden place. In this trench there are two sections of the Grand Canyon formed by the confluence of different submarine mountains, the most thrilling of which is only more than 30 meters narrow, but the length is 50 nautical miles long, and the curve is very large. Big nuclear submarines can't get through. The more than 300 nautical miles around this canyon are rocky beaches, with an average water depth of less than 20 meters, and no other boats can enter except for small fishing boats, even if we cannot escape the pursuit of enemy nuclear submarines in other canyons. Then it's definitely okay here.

In addition, there is an area of ocean current disturbance at both ends of this Grand Canyon. You see, here, this is the northern end of the Grand Canyon, and the currents of the southeast Pacific Ocean flow from the east, and because of the high temperature, low density and the influence of the topography in front of it, it is in this place that the upper reaches of the sea rush from the surface into the northwest Pacific Ocean. The Northwest Pacific current, on the other hand, is affected by the depth of the ocean floor due to its low temperature and high density. The ocean current rushes from the lower layer of the sea surface to the southeast Pacific Ocean, and the two hedges make the sea situation here very complicated, and ordinary conventional submarines dare not enter this area. Because the turbulent current with strong power can make the submarine roll, guide the submarine to the bottom and destroy the boat. And nuclear submarines can, because below 200 meters above the sea surface, the sea water is relatively stable. But they're too big to get through those tight bends.

So. This area of the sea is equivalent to tailor-made for our submarines. Because our submarines can dive to a depth of 200 meters, and the size of the nuclear submarine is small, and the endurance of our submarine is long after adopting the AIP system, it has the advantages of both conventional submarines and nuclear submarines. In short, we can carry out all kinds of training under various conditions, and we will be able to find out the performance of the opponent's submarine without leaking our own situation. Of course, the voiceprint of our submarine will be recorded by the other side, this is something that cannot be done, in the event of a confrontation with each other, we cannot stop the transmission of sound unless we sink each other. ”

Hearing these convenient conditions, Guo Zhuocheng was also as happy as Jiang Haitao and the others, and he was a little eager to try.

He couldn't help but ask: "Chief of Staff Ma, has this submarine of ours sailed through this trench in its entirety?" Suppose we retreat when we are entangled with the other side, and the other party happens to be a submarine with an AIP system installed, and there is also a long period of high-speed diving, can you conclude that we can get rid of them? ”

Ma Yanshu was stunned for a moment, and said hesitantly: "This ......, we really haven't run the trench completely, but it has been sailed by different submarines in sections, after all, this submarine has only been put into service, and the previous submarines can only meet one of the requirements, and we have planned to run back and forth in this trench a few times to familiarize ourselves with the terrain." It is indeed possible that there is a submarine chasing after you, a submarine blocking the front, and an aircraft searching in the sky. In this case, we are really troublesome, unless we run the entire trench several times, and we have formulated relevant emergency plans in advance to identify relevant important places. ”

Guo Shucheng said: "Then don't rush to attack before you are familiar with this trench, and don't track down or play tricks on other countries' submarines." Although we think that my submarines are good, it is not necessarily that other countries do not have unique methods. Submarines are weapons hidden in the shadows, and the skill level of others can only be guessed. Tai-zu has long said that strategically we should despise the enemy, but tactically we should attach importance to the enemy. ”

Jiang Haitao nodded seriously and said: "Political Commissar Guo is right, we are a little hot-headed now, thinking that except for the submarines of the United States, which are better than us, the submarines of other countries cannot be compared with us. It is estimated that in the minds of some of our cadres, even US submarines may not be as good as ours, and this kind of thinking of underestimating the enemy will suffer great losses in the future. Although our current submarines are far better than the previous ones, we are just comparing ourselves to ourselves, and we don't know the situation of others, so it is better to be careful and safe. From tomorrow, we will continue to do the training of the base and continue to familiarize ourselves around the Night Pearl Island. Political Commissar Guo, please re-examine the relevant training plan with us. ”

After listening to Jiang Haitao's words, Guo Shucheng hurriedly said: "You are experts in submarines, you still follow the plan you originally formulated, as long as you pay attention to safety." You can rest assured that a world war will not happen for a while and a half, and we have time to train, time to prepare, and opportunities to track and drive other ships in the future. As the saying goes, sharpening knives is not wrong for woodcutters, and doing a solid foundation first must only have benefits and no harm. Just let me know when your training plan is finalized. ”

The meeting ended when the future course of action was determined. Jiang Haitao, Ma Yanshu, and other military personnel began to revise their training plans, while Guo Zhuocheng, a temporary political work cadre, began to talk to the officers and men, showed concern for their living and psychological conditions, asked them for their opinions and suggestions, and helped them solve some practical problems......

The next morning, more than 50 officers and men stood in high spirits on the huge submarine dock. In front of them was the mighty AIP submarine, quietly waiting for the soldiers to come up and sail it across the field.

Most of these soldiers were transferred from other places, like Second Lieutenant Chen Fangping, who had not yet been on this new submarine. The soldiers' eyes were full of joy and longing. Again and again they raised their already high heads, because of their excitement. His hands were tightly clasped on the seams of his trousers on the left and right sides, and his palms were slightly sweaty.

They waited for the arrival of the submarine commander, and although they had only waited for a few minutes, they felt that the wait was too long, and one of the mischievous soldiers even secretly turned his head and looked behind him at the door of the officer's conference room, causing the officer on duty to shout.

Officers also meet in conference rooms to make pre-training arrangements and announce relevant training plans.

Suddenly there was a powerful sound of footsteps on the ground, and the warriors' emotions were even higher: their heads were raised again, their chests were raised again, and their hands were once again stretched out.

"Stand up!" The officer on duty shouted loudly.

I heard only the sound of neat feet. The soldiers seemed to be breathing much quieter.

"Report to the captain! The first batch of people to go to sea should be fifty-four, but it is actually fifty-four, please instruct! Officer on duty, Lan He! The officer on duty ran in front of Jiang Haitao in a few steps, stood up and saluted hard, reported loudly, and then turned his upper body to salute Guo Zhuocheng and several other officers next to Jiang Haitao.

Jiang Haitao, Guo Zhuocheng and other officers immediately raised their hands to salute in return. The officers stand upright, raise their hands, hold their chests up, tuck their abdomen, and let go of their hands in a uniform manner, from which they can have good military qualities.

"Take a break!" Jiang Haitao ordered.

"Yes!"

……

Through this set of strict movements, the feelings of the fighters are even higher.

Jiang Haitao is now standing in front of this group of energetic young men and began his pre-war mobilization: "......, our task this time is to find out our passage to the sea and establish our own lifeline. Only with a safe and confidential lifeline, in which we can advance and retreat freely, can we advance and retreat.

Only then can we fight the enemy and protect ourselves. It can be said that mastering the sea conditions and terrain in this area is more important than sinking one or two enemy ships in the future. I won't talk about its importance, and I think you know that. I am here just to remind comrades that fighting a war is exciting, refreshing, and important, and this is also the purpose of our formation of this unit. But the preliminary preparation is more important, and it requires the carefulness and seriousness of the brothers. Brothers, do you have the confidence to fully grasp the sea situation and topography here? Jiang Haitao suddenly provided a tone and asked loudly.

"Yes!" The fighters replied loudly.

"Again, do the brothers have confidence?" Jiang Haitao asked loudly again.

"There's-!" Now the roar was louder and more uniform.

Jiang Haitao nodded with satisfaction, and roared firmly in his mouth: "Board the boat!" ”
