"What the hell are you thinking?" Igor flicked the cigarette butt into the sea.

"What did you say?" Captain Robin asked with a quick turn, blinking.

"You don't really want to eat any Japanese supplies, do you?" Igor turned his back against the fence, his eyes glancing at the captain with a mocking expression on his face.

"You're right, I'm really interested in the food of the Japanese Navy, and I've heard that they eat quite well." Robin put his elbow on the shell and dusted his cigarette into the sea.

"Okay, they're ready to stop the ship, and when the time comes, you'll either go over by yourself or let the Japanese come over." Igor scratched his nose and turned to face the sea.

"Would you like to go to a Japanese submarine?" Robin asked, tilting his head.

"Wait a minute, do you really believe they'll agree to your request?" Igor covered his mouth exaggeratedly, pretending to be surprised.

"The two cars stopped, the deck crew took their positions, and the rubber boats No. 1 and No. 2 were unloaded." Robin didn't stumble, he turned his head to the intercom tube and commanded loudly.

"Stop, Captain." From the entrance and exit of the conning tower came the muffled voice of the navigator.

"Current heading 275, Captain."

"Have you calculated the ship's position?"

"10 degrees north latitude, about 111 degrees east longitude, sir." The third officer looked at the reading report on the sextant.

"We're still in M99." Igor asked, surprised, as he had not expected.

U106 and U1001 have been circling underwater for most of the day, and it stands to reason that they should be a little further west now.

"Yes, sail fifteen kilometers further southwest before we can enter LG33." The value officer is very confident in his calculations.

The M and LG they are talking about here refer to the famous checkered coordinate numbers of the German Navy. The German Navy divided the world's seas into coordinate squares, each of which was subdivided into nine equal parts. Each large coordinate square has an independent number consisting of two letters, and the nine squares are numbered 1-9 from left to right and top to bottom.

Then, on small-scale nautical charts, these numeric grids are subdivided into nine small squares, and are also numbered 1 to 9 in the same way. This coordinate positioning system is very simple to use, for example, the M99 area mentioned above, which refers to the No. 9 coordinate grid in the square numbered 9 in the lower right corner of the large coordinate grid of M, and the square sea area with a length and width of 100 kilometers each.

In fact, they can continue to subdivide according to this method until it is accurate to square kilometers, but how to delineate it depends on the needs of the specific task.

The German Navy's coordinate grid system is a top military secret, because both submarines and warships will use this system on the radio to report their ship positions to their superiors, and the superiors will also use this set of coordinates to inform the location of the enemy forces found, as well as the fleet's supply and rendezvous points at sea. Therefore, once the enemy obtained the coordinate map and communication code, it was equivalent to exposing all the positions of the German naval ships to the enemy.

Historically, after 41 years, the German submarine was ambushed by the Allied anti-submarine forces in the assembly area notified by the superiors because the Allies captured a coordinate map and communication key, and the German submarine wolves were repeatedly ambushed by the Allied anti-submarine forces in the assembly area notified by the superiors, and several ace submarines were lost one after another.

In order to avoid this situation from happening again, because the warship is sailing on the vast sea, God knows what problems will be encountered, Xu Jun now stipulates that every two months, the navy must change the letter number of the coordinate grid, in fact, this is not very troublesome, just shuffle the alphabetical order back and forth, only need to spend some printing ink and waterproof paper money, in exchange for the life safety of German naval officers and soldiers, no matter how you look at this deal is very cost-effective.

"The Japanese captain replied, thank you for the invitation, and he looks forward to meeting with you." Igor smiled as he translated the international flag issued by the Japanese submarine.

"It seems that the Japanese have their own plans, so that's fine." Robin straightened his back and looked at the I-60 submarine with a flat expression.

With an extra roof and some accessories, the Japanese submarine's conning tower looks a cut above the U106. In addition to a large 12-centimeter telescope in the middle, a large winding spool was installed on the left and right sides of the roof, and a radio transmission cable was towed from each to the bow, showing an acute V-shape when viewed from above.

The bow of the I-60 boat is equipped with an anti-submarine net cutting saw, which is exactly the same as the one installed on the U106, because it comes from the same technical heritage, so the two submarines of Germany and Japan are indeed somewhat similar in appearance. However, compared with the huge and clumsy Haida III, the German UIX is more hideous, especially the rows of sinking signs painted on the shell of the U-boat conning tower, which reminds others all the time that this is a war machine with many achievements.

Compared with the U106, the Yi-60's conning tower enclosure looks much "cleaner", in fact, this submarine has not obtained any actual combat records since its birth, unless the Japanese Navy shamelessly counts the unlucky Yi-63.

"Sure enough, it's the trump card submarine of the only country." Captain Hua Fang Shaozuo admired with admiration. Only a true submarine captain can understand how hard and difficult it is to search for and sink an enemy ship in the open sea.

"Down!" The first officer, who was also the deputy captain of the ship, Captain Ohashi, personally commanded the deck detachment on the deck at this time, operated the crane, and hoisted the folding rowboat into the sea.

The I-60 carried four dinghies, two large inflatable life rafts, a medium-sized inflatable rowing boat, and a wooden folding rowing boat. This wooden dinghy is usually used as a transport boat to and from the shore ship when it is floating in the berth area of the military port, and can carry 12 officers and men or logistics supplies of the same weight.

The wooden rowboat, painted conspicuously white, was lowered to the surface, and the sea was calm and the dinghy stopped steadily next to the submarine. The captain of the deck detachment jumped into the dinghy with a cable in his hand, and then another sailor jumped in, and the sailor detachment who remained on the deck cooperated to tighten the tow rope at the front and rear of the dinghy, and fixed the dinghy to the side of the boat, and then a plank rope ladder was lowered into the rowboat along the hull.

"Commander, it's all ready." Hanafang took off his navy tropical rattan helmet and replaced it with an officer's battle cap.

Unlike the tropical cork helmet of the Germans, this tropical rattan helmet is completely the shape of the Vietnamese cool helmet of later generations, the whole body is woven with rattan, and the outside is covered with a layer of navy blue cloth helmet, which was only issued to officers and senior sailing non-commissioned officers on the boat in the early days, for them to wear when they are on duty outside the boat.

At this time, Guidao had gone to the cabin to change into a set of white summer clothes, wearing a naval officer's hat with a white summer cap, and his Zhao XII naval saber hanging from his waist.

Of course, the saber of the Imperial Japanese Navy should be different from the iron bar of the army red deer, to be honest, the saber of the Japanese Navy has more ceremonial factors than the Japanese Army, just like at the end of the shogunate period, the Japanese sword is no longer a weapon, but only a samurai identity certificate, the saber of the Japanese Navy does not pay attention to its actual combat, but has become an important symbol of the samurai identity of the officer.

Although the Japanese officers have received strict kendo training, it is only a way to exercise their personal combat awareness, and in naval battles that are thousands or even tens of thousands of meters apart, sabers do not work at all, and they do not necessarily let officers jump over with sabers to slash and kill the enemy, which is not a time to enter the Caribbean movie.

However, it is also a bit of an absolute to say that the naval saber is useless, because defeated naval commanders often use this saber to cut their abdomen and publicly display their large intestines.

The ceremonial nature of the naval saber did not prevent them from having a separate psychology from the army, and the navy's Zhao XII style presented a kind of navy-style luxury, and almost every one of them could be called a masterpiece. Compared with the army saber, the navy saber has several obvious differences, first of all, the scabbard, which is coated with a layer of glossy black primer on the outside, and the parts such as the knife hanging are all gilded, and the other is the pattern on the sword, the army's standard sword is almost rectangular, and the four corners are cast with the army's cherry blossom military emblem, and the navy is an oval light plate, engraved with a circle of radiant lines, completely copying the pattern of the rising sun flag.

The number of sabers captured by the Japanese Navy in history is much smaller than that of the Japanese Army, mainly because most of the sabers have sunk into the sea with their owners.

"The German submarine replied, welcome to board the ship." The Signal Soldier reported excitedly and loudly.

"Reply, thank you again." Hanafang took the navy dagger from the vice-captain's hand, fastened it to the hook of the officer's belt, and then descended the rope ladder to the rowboat.

"Roar, let's go!" Seeing Hanafang boarding the dinghy, Nakasa, who had long been impatient, stood at the bow of the boat, pointed to the German submarine and gave a loud order.

ps: I'm sorry.,I'm not feeling well.,There's only one chapter left today.,The chapter you owe will be made up tomorrow or the day after tomorrow.。

I went to rest, thank you for your support.
