Demon School
Chapter 638: The power of new batteries
"... Stop!" At the moment of approaching the critical distance! The sweaty Colonel Grant issued an order! After ascending, you can also pray for the Chinese navy to let itself go! But if it hits, I am afraid it will be more serious! At the last moment, he finally lost the courage to the Chinese navy! Helplessly issued an order, "Let's float up!"
Being forced out of the water is the biggest shame for the divers! Can hear Grant's order, up to executive officer Billy Hellington, down to George Carlson who just joined the submarine, no one was ashamed, Fan Er took a long breath! Thank you for Grant ’s final decision!
If you can live, no one wants to die! The consequence of the impact is that they can't bear it anyway! "Lieutenant Colonel, shall we continue to leave after surfacing?" The soldiers after the robbery asked about the next step.
"No, stop after floating on the surface and open the boat door! I want to see what model the ghost was just now!" This floating has made Grant lose face, and he might be punished by his superiors when he returns! But if you can get information about your opponent's new submarine, you might be rewarded by your superiors!
"Yes, Lieutenant Colonel!" The submarine slowly ascended, and soon it rose to the surface. Lieutenant Colonel Grant could not wait to open the boat door, and greedily breathed a long-lost fresh air. He was drunk! Then Billy-Hillington and others also came out and stood on the bridge.
"Judging from the position just now, it may be there if they will also float!" Billy Hellington holding the telescope pointed far away.
"If it is a new type of submarine, I think the Chinese Navy might not ..." Before half of the words, Billy-Hillington closed his mouth and put his eyes close to the telescope , "I saw the periscope! The ship directly in front is about to pay the water!"
"So is the rear!"
"There is also a right front!" The two soldiers almost discovered the submarine that was about to float with his colleagues.
"Give me the camera!" Grant grabbed the camera from George's hand and pointed the lens directly in front of it, the submarine closest to it. "Come on baby, let me see what you look like!"
"God! How is it possible?" Grant stopped the operation as soon as the shutter was pressed twice. Unbelievably, he looked at the submarine with a very familiar shape not far away. "Isn't this model the Song class conventional submarine of China?"
"So are the other two ships!" Just a moment ago. Billy-Hillington has swept the telescope around, and has a panoramic view of these three almost identical submarines!
"How did they catch up with us? The data of the Song-class conventional submarine is kept in my mind! It may show some of the performance just now!" Grant took the telescope from Billy's hand and almost pressed the eyepiece to his eye socket. in.
"When I was only one nautical mile away from the other party, I found that this submarine looks like the Song class! But the noise model is completely different from the Song class!" The tormented sonar soldier also interjected, "And If it is the Song class, I must have discovered them already! "
"Is it a new model of the Song class?" Grant asked suspiciously, but in an instant he overturned his guess. "But look at the shells of these submarines. They have been in service for some time!"
"This is China's territorial waters, please leave immediately!" The submarine directly in front of this time heard a loud horn, and the Chinese soldiers on the bridge shouted in standard English.
"Go! We will get into trouble if we don't go!" Billy-Hillington climbed down first! Then came the sonar soldiers and George! Grant stayed at the end. He glanced at the three submarines before he climbed slowly. Then this Los Angeles-class nuclear submarine slowly sailed out of China's territorial waters under the supervision of three conventional submarines!
A few days later, at a naval base in China, all the officers and men of these three submarines received a warm welcome from the base. "You have given us a navy face this time! I have already reported your credit to your superiors. How long will you receive the award after making up! "
"Thank you, Chief! But I dare not take credit for it. This is the effect of the modified submarine. It is the same even if you change someone else!" Major Li Changgan, the leader of the submarine unit, replied.
"This time the weight of the battery has been reduced by one-third, but the stored energy has more than doubled! And the noise of the propeller and the main gear reduction gearbox processed by the new technology has been greatly reduced! The speed of underwater navigation is even more Great improvement! If we still ca n’t catch up with a Los Angeles class, then we do n’t have to be in the navy! ”Li Changgan gave all the credit to the reconstruction project.
At present, conventional submarine batteries are still dominated by lead-acid batteries. The specific energy of lead-acid batteries is about 35-45wh / kg. General conventional submarines require 1-2 hours of full speed submarine capability, or 3-7 days of low speed submergence capability. According to the estimation of a conventional submarine with a displacement of 1,500 tons, the battery usually costs about 50-100 tons.
With the new battery technology, the weight of the battery has dropped to 60 tons, but the energy contained allows them to have a full-speed navigation capability of 4-8 hours and a low-speed latent ability of 2 to 3 weeks! This is enough to expand its monitoring scope to the position reached by Colonel Grant's Los Angeles class.
The biggest noise source of the submarine is the propeller and the main engine reduction gear box, and the adjustment of these two parts makes the noise emitted by them decrease in amplitude, so until the Los Angeles class is surrounded, their sonar soldiers have not found it!
"Haha! Something is a good thing! But some people will use it!" The base commander patted Li Changqian's shoulder intimately. One copy! This will be an important basis for us to study the improvement work of the new submarine and the Los Angeles class! "
"Yes! Guarantee to complete the task!" Li Changqian immediately stood up and saluted.
"Lieutenant Colonel! Are you sure that you are hallucinating because you are taking more drugs?" Among the neon Rice Army Naval Base. Lieutenant Colonel Grant is also accepting inquiries from all parties!
"Absolutely not wrong! I still have photos taken at that time, judging from the style of the shell. They are definitely Song class conventional submarines!" Grant took out the camera and placed them in front of these people!
"Gosh! How is this possible?" The senior officials of the Naval Base of the US Army also fell silent. (To be continued.)
ps: Thanks to the quiet and handsome 5888 local tyrants for their rewards, thanks to iam, non-influential associates, looking up at the stars into stars, civilization and miracles, Qi Qi, thin enough, ykwfox711, where is the reward for others, thank you Everyone's monthly ticket! The mother's starting point has been drawn again, and the reward details cannot be found in the background!
