"Stop!" At the moment when he was close to the critical distance! Lieutenant Colonel Grant, who was sweating profusely, issued the order! After surfacing, he could still pray to the Chinese Navy to let him leave! But if there was a collision, it would probably be much more serious! At the end

At this moment, he finally lost to the courage of the Chinese navy! He reluctantly issued an order, "Let's float up!"

Being forced out of the water is the greatest shame for a diver! But after hearing Grant's order, no one from the executive officer Billy Herrington to George Carlson, who had just joined the submarine, showed any shame.

Fan'er let out a long breath! She was very happy for Grant's final decision!

No one wants to die if they can live! The consequences of the impact are something they cannot bear no matter what! "Lieutenant Colonel, shall we continue to leave after we surface?" The soldier who survived the disaster asked about the next plan.

"No, stop after surfacing and open the door of the boat! I want to see what model the ghost just now is!" Grant has lost face after surfacing this time. He may still be punished by his superiors after returning! But if he can

Obtain information about your opponent's new submarine, and you might even be rewarded by your superiors!

"Yes, Lieutenant Colonel!" The submarine slowly surfaced, and soon it came to the surface. Lieutenant Colonel Grant couldn't wait to open the door of the boat, and took a greedy breath of fresh air that he hadn't seen for a long time. The air with the salty smell of the sea breeze made him

He was fascinated by it! Then Billy Herrington and others also came out and stood on the bridge.

"Judging from the position just now, if they also float up, they may appear in that position!" Billy Herrington, holding a telescope, pointed forward in the distance.

"If it is a new model of submarine, I think the Chinese Navy will not..." Before he was halfway through speaking, Billy Herrington closed his mouth and moved his eyes tightly to the telescope.

, "I saw the periscope! The ship directly in front is about to sink into the water!"

"The same goes for the rear!"

"There's also the right front!" Two soldiers almost discovered the submarine that was about to surface with their colleagues.

"Give me the camera!" Grant grabbed the camera from George and pointed the lens straight ahead, which was the submarine closest to it. "Come on, baby, let me see what you look like!"

"

"Oh God! How is it possible?" Grant stopped the operation just after pressing the shutter twice, looking at the very familiar submarine not far away with a look of disbelief on his face, "Isn't this model a Chinese Song-class conventional submarine?

?”

"So are the other two!" In just a moment, Billy Herrington had already scanned the circle with his telescope and had a panoramic view of these three almost identical submarines!

"How did they catch up with us? I keep the data of the Song-class conventional submarine in my mind! It may partially show the performance just now!" Grant took the telescope from Billy and almost pressed the eyepiece to his eye socket.

inside.

"When we were only one nautical mile away from the opponent, I discovered that the appearance of this submarine was very similar to that of the Song class! But the noise model was completely different from that of the Song class!" The sonar soldier who had been suffering just now also interjected, "And

If it were the Song class, I would have discovered them long ago!"

"Is it a new model of the Song-class series?" Grant asked suspiciously, but in a flash he overturned his guess, "But looking at the shells of these submarines, they have obviously been in service for a while!"

"This is China's territorial waters, please leave immediately!" At this time, a loud horn sounded from the submarine directly in front, and the Chinese soldiers on the bridge shouted in standard American English.

"Let's go! If we don't go, we will get into trouble!" Billy Herrington climbed down first! Then came the sonar soldier, George and others! Grant stayed at the end, and he reluctantly looked at the three ships.

The submarine glanced at it before slowly climbing down. Then the Los Angeles-class nuclear submarine slowly sailed out of China's territorial waters under the surveillance of three conventional submarines!

A few days later, at a certain naval base in China, all the officers and soldiers of these three submarines received a warm welcome from the base, "You have done a great job for our navy this time! I have already reported your achievements to my superiors.

How long does it take to make up for it and you will all receive the reward!"

"Thank you, chief! But I dare not take credit. This is all the result of the modification of the submarine. Even if it were replaced by someone else, it would be the same!" Major Li Changqian, the leader of the submarine team, replied.

"This time the weight of the battery has been reduced by one-third, but the power reserve has more than doubled! Moreover, the noise of the propeller and main engine reduction gearbox processed with new technology has been greatly reduced! The speed of underwater navigation is even faster.

The improvement is huge! If we can't catch up with a mere Los Angeles-class ship, then we don't need to be in the Navy anymore!" Li Changqian gave all the credit to the renovation project.

At present, conventional submarine batteries are still mainly lead-acid batteries. The specific energy of lead-acid batteries is about 35-45wh/kg. Generally, conventional submarines require 1-2 hours of full-speed submersible capability, or 3-7 days of low-speed latent capability.

.Based on the estimation of a conventional submarine with an underwater displacement of 1,500 tons, the battery usually costs about 50-100 tons.

With the adoption of new battery technology, the weight of the battery has been reduced to 60 tons, but the energy contained allows them to have a full-speed navigation capability of 4-8 hours, and a low-speed latency capability of up to 3 weeks! This is enough for its monitoring

The range was expanded to the point reached by Lieutenant Colonel Grant's Los Angeles class.

The biggest noise sources of submarines are the propellers and main engine reduction gearboxes, and the adjustment of these two parts has reduced the noise they emit when driving. Therefore, until the Los Angeles class was surrounded, their sonar soldiers did not notice it!

"Haha! The thing is a good thing! But it needs someone to use it!" The base commander patted Li Changqian's shoulder affectionately, "Write down the detailed process of how you forced the Los Angeles-class nuclear submarine to the surface this time! This will

It is an important basis for us to study the improvement work of new submarines and the Los Angeles class!"

"Yes! I promise to complete the mission!" Li Changqian immediately stood at attention and saluted.

"Lieutenant Colonel Grant! Are you sure you are not hallucinating because you took too many drugs?" In the Neon Navy Naval Base, Lieutenant Colonel Grant is also accepting questions from all parties!

"You're absolutely right! I still have the photos I took here. Judging from the style of the shell, they are definitely Song-class conventional submarines!" Grant took out his camera and placed it in front of these people!
Chapter completed!
