"Let's drink this bowl of wine today and set out with endless joy! Expedition to the land of the rising sun, ah, we to the land of the rising sun! My dear girl, when you receive the letter I left and this medal, I have blessed you in heaven, bless you, my most beautiful girl, when night falls, when you look at the sky, please do not forget that the most beautiful star is my eyes on you"

Next to the port in Vladivostok, hundreds of navy officers in crisp white naval uniforms are singing songs and marching in a neat line towards the port. They are the officers and men of the Chahar Naval Submarine Group, which sank the Japanese Navy's "Kaga, aircraft carrier not long ago", and today they are here to receive new submarines.

After leaving the wharf, more than 600 naval officers and sailors got into the trucks that had been parked on the side of the road long ago, and the trucks drove quickly towards a small naval base more than 30 kilometers away from Vladivostok.

In the car, Mu Yu, who wore the rank of freshly baked lieutenant colonel, couldn't suppress the excitement in his heart, since the sinking of the "Kaga, the aircraft carrier, the personnel of the four submarines of the submarine brigade have all been rewarded and promoted by the headquarters because of their great achievements, and Mu Yu's military rank has also been promoted from two cents to two cents. And from today onwards, he will officially serve as the captain of a submarine, although the difference between the second and the boss is only one word, but the difference is huge, which makes Mu Yu's heart flutter a little.

Long Yu on the side was also happy for his friend's ascension, but for the sake of his friend, he also had to remind his friend.

"Mu Yu, I'm very happy for you to be promoted, but you must remember that from today onwards, you will be a captain, submarines are no better than surface ships, once an accident occurs, it will be the result of the destruction of the ship, and the lives of dozens of people on the boat are in your hands, you must not be careless!"

Mu Yu looked at his mentor and friend gratefully, and said with some emotion: "Don't worry, I will definitely be rich, and I will never smear the face of our submarine team." ”

"Good job!" Long Yu patted Mu Yu on the shoulder and smiled, "I believe that with your ability, you will definitely be able to become an excellent captain." ”

An hour later, the truck drove into a small base, and after the car entered the base, all the officers and men were allowed to enter. When everyone entered the interior of this base, they found that this base was actually built in a particularly large underground cave. The width of this karst cave has reached more than 300 meters, which is long for several miles, which is enough to accommodate hundreds of submarines to dock at the same time, and there are many engineers belonging to the navy walking around on the edge of the cave, and Zhang Shouye, chief of staff of the Chahar Navy, is standing on the dock waiting for them.

After everyone came to Zhang Shouye, Long Yu strode forward and saluted, and then reported: "Report to the chief, all the personnel of the Chahar Navy Submarine and Submarine Brigade have come to report, please instruct." ”

Zhang Shouye also said solemnly: "Take a break!" ”

"Stand upright!"

"Brave sailors, today I see that the submarine group has added eight more submarines, and our personnel has grown. This gives me great satisfaction that the strength of our Navy's surface ships is still very weak, so some of the regular ocean-going patrol tasks that were originally undertaken by surface ships have been put on your shoulders. This is a great task before our large surface ships are in service, and at the same time I believe that you can complete this glorious and difficult task, brave sailors, do you have the confidence to accept this challenge? ”

As soon as Zhang Shouye's words were finished, the sailors in front of him roared loudly and neatly: "I am born and the country will die, and I will die and the country will survive." ”

"Good!" Zhang Shouye nodded with satisfaction, "Next, I will officially hand over the eight new submarines to you, I hope you will love them as you love your own lives, and drive them to make new contributions to our country, everyone get on board." ”

Although these submariners have known and figured out the new submarine countless times in the data, they still feel very happy every time they see the real thing.

This is an improved "R" class (Romeo-class) submarine by the 613 type submarine of the former Soviet Union in the future, with a displacement of 1,475 tons and 1,830 tons (surface corpse underwater) Compared with the German submarine at this time, it has improved the performance of underwater acoustic equipment, increased the water cooling system of the battery, increased the depth of diving, and the state of the snorkel as the main navigation state has increased the speed, and the way of converting the reserve buoyancy into overloaded fuel has cleverly doubled the endurance and self-sustaining force. As a result, the power plant was not changed, and the underwater speed of the boat remained unchanged after the displacement was increased, thanks to the improvement of hydrodynamic and propulsion characteristics. This makes it reach a range of 9,000 kilometers and a depth of 300 meters.

At this stage, due to the lack of naval personnel of our army, the navy of Dechahar is forced to take the road of building a military with quality, and this submarine with the level of the 50s in the later generations is just within the acceptable range of the current naval sailors. If it is too advanced, it will be difficult for submarine sailors to master, and it will be too suspicious.

Seeing that the soldiers entered their respective submarines under the leadership of their respective captains, but Long Yu did not act, Zhang Shouye walked to Long Yu's side with a smile and asked, "Colonel Long, why don't you lead the team down to see the new submarine?" ”

Long Yu smiled, "They can be taken down by the sergeant major, and as for the submarine, they can watch it at any time in the future, but Chief of Staff Zhang's teachings are not something that can be heard every day." ”

Zhang Shouye pointed at Long Yu with a little crying and laughing, "How can you kid learn to slap the horse." ”

Long Yu smiled and asked, "Senza, you tell me the truth." How much time did the boss give us to get acquainted with this submarine? ”

After hearing this, Zhang Shouye stretched out a finger with a somewhat solemn expression.

"What? One month! Long Yu exclaimed in disbelief, "Could it be that our time is so tight?" Can't even give us three months? ”

"Yes!" Zhang Shouye nodded, "After the Japanese Navy suffered a big loss last time, it has once again increased the investment of the Navy, and according to the report of our Investigation Bureau, they are now building two super battleships and three aircraft carriers. And their navy has also increased the blockade of our ports, and their ships often cruise outside the flight radius of our shore-based aircraft, so that our surface ships are blocked in the inland sea, and only your submarine group can break through the blockade of Japanese ships and aircraft carriers. ”

Long Yu gritted his teeth and said straightly: "Report to the chief, the submarine team guarantees to complete the task!" ”

Zhang Shouye nodded with satisfaction, "Now the Japanese ships and aircraft carriers are living outside the flight radius of our shore-based aircraft, cutting us off from the outside world. As a result, several batches of German supplies that were supposed to enter Vladivostok through the water had to be transferred in through the port of Guangzhou, which was a great shame for all our naval officers and men. I hope that in a month you will be able to sink a few Japanese ships on the surface of the sea and deal a severe blow to their arrogance, can you do that? ”

Looking at Zhang Shouye's expectant gaze, a sharp light flashed in Long Yu's eyes, and he solemnly saluted Zhang Shouye, and promised loudly: "Please rest assured, our submarine brigade was originally from this background, and when it comes to underwater ambushes and ambushes, it is our specialty." You'll be able to wait and see after a month! ”

Zhang Shouye patted Long Yu's shoulder, "Well, do a good job!" ”

Not to mention that Longyu is seizing the time to familiarize himself with the new submarines and strive to form combat effectiveness in the fastest possible time.

At this time, 500 kilometers away in Peter the Great Bay, a formation of ships with ointment flags was swimming on the sea, headed by a huge battleship, which was the "Fuso, a battleship" belonging to the Japanese Combined Fleet, which belonged to the first generation of Japanese battleships, built at the Wuxian Naval Shipyard, started on March 11, 1912, launched on March 28, 1914, and completed on November 18, 1915 with a standard displacement of 30,600 tons. He has been more than 20 years old, and he is already an older ship, so he is only now being sent to carry out these relatively easy cruises.

The commander of this fleet was also the "Fuso", and the captain of the ship, Jizaburo Ozawa, was standing on Cambridge in a straight naval uniform, and he had been holding a telescope to look into the distance for half an hour, but he still did not put the telescope down.

This strange behavior made Chief of Staff Fukuda Nakasa, who was standing behind him, feel very strange, and he asked a little strangely: "Your Excellency, are you still looking into the distance at the merchant ships of the Germans that we expelled a few days ago?" ”

Jizaburo Ozawa glanced back at his chief of staff and said, "Fukuda-kun, I'm not worried about the warships of the Germans, but about the submarines of the Shina people. We have now blocked the sea lanes of the China, and the China will certainly not give up, they will definitely find a way to retaliate, and the only ships they can use are their submarines. ”

When it comes to Chahar's submarine, Fukuda Nakasa can't help but shudder, after sinking the Japanese "Kaga, aircraft carrier", the submarine force of the Chahar Navy can be regarded as famous. As the world's first submarine force to sink an aircraft carrier, Chahar's equipped ocean-going submarine has also become famous in the world, and at the same time, the German submarine force, which has not yet officially appeared in the world, has been on fire in advance. You see, the apprentices are so powerful, so isn't the German submarine force as a division even more powerful?

And after suffering such a big loss, the Japanese also began to pay attention to the anti-submarine work that they had always neglected.

This is also a windfall for the Japanese Navy.
