Deng Jieqian deliberately controlled the speed, and when night fell, he arrived in the waters near Brazil, which is at least 350 nautical miles deep into the North Atlantic Ocean off the coast of Brazil, and can no longer be called the coast of Brazil.

After arriving, after measuring the position with a measuring tool, Deng Jieqian sent out radio waves at a fixed point according to the agreement, and the radio waves contacted the supply ship located near the reserved place, which was also the last supply ship in the whole plan, and they would do a complete supply and maintenance operation for the entire fleet.

High-frequency radio waves quickly penetrated the space and propagated, and soon, in the special channel, the feedback information came back, the radio has many frequency bands, through special processing, special frequency bands can be obtained, and the requirements for electronic products are extremely high, which is also one of the methods of secrecy at present, very simple, but very effective, at least according to the height of China's research on radio, under the premise that there is no all-in-one machine to support various electronic components, it is impossible to transmit and receive this radio wave.

According to the order, a flotilla of at least 7 supply ships returned here to replenish their fleet, and sure enough, only about 5 minutes later, the contact signal of the special channel sounded, and after the two sides determined the password and location, a long wait began.

It is located in the South Atlantic Ocean, although it is on the Brazilian side, but it is about 350 nautical miles away from the Brazilian shore in a straight line, in a sense, it has been calculated to go deep into the Atlantic Ocean, and it is not close to any shipping route, even if it is a submarine is safe here.

After passing through Africa, Deng Jieqian was very careful, even if he had already reached the predetermined sea area. Completed several determinations with the supply ship in code, for insurance. Only 2 submarines are located above the surface of the sea and are waiting to replenish the fleet. The other submarines, all ready for battle, dived into the water, and the farthest even with the ships that came out of the water, more than 2 nautical miles, which was a relatively safe distance, in case something happened, they either came to support, or simply turned around and left. The underwater speed of 16.5 knots is the guarantee of Qin-level safety.

Being in a foreign country, with no allies and help around, the best choice for Deng Jieqian is to be cautious, although he has eliminated the fleet from Australia, the warship at that time has entered the danger zone of 5 kilometers, if the other party is advancing at full speed. At a speed of about 35 knots for the destroyer, 5 kilometers is four or five minutes at most, and if the other side conducts a strict lookout, they may only be able to escape. It also depends on whether the other party is willing to pursue, and he is never willing to do it again.

In fact. The pair of supply ships did not make them wait long, almost half an hour later. Seven supply ships appeared in the submarine's field of vision, flying the Brazilian flag. China has no sphere of influence overseas. It is impossible for all supply ships to fly the Chinese flag, unless they are replenished in China's inland coastal defense circle, and the Chinese flag will be hoisted.

War has been declared at present, and most of the Chinese ships will not appear in the war zone, otherwise they will definitely be attacked by the Entente fleet, these supply ships are flying the Brazilian flag, but before they come, they have been contacted by radio, they will hang a secret flag at the highest position in the bow, and write a Chinese Chinese character on the basis of the original Brazilian flag.

The fluorescence is very shallow, but it can be seen through a special telescope, Deng Jieqian saw the agreed code, and immediately went to contact, for China's confidence, as long as the signal is correct, basically there will be no problems, plus, they only have two ships, even if there is a problem, other ships can also react.

There is no problem, 7 ships are supply ships from China, this kind of modification on the basis of 10,000-ton merchant ships, on the surface it is an ordinary standardized merchant ship, but in fact, his carrying capacity is only 2300 tons, far from the rated 10,000 tons, but more are handed over to a variety of auxiliary equipment, such as comprehensive tower cranes, or oil pipelines, etc., even the speed, this seemingly 10,000-ton standard cargo ship, but has a strong enough structure and fluid, It can travel at a speed of about 22 knots at the fastest, and basically, it can catch up with the speed of the capital ship.

In hidden considerations, the appearance of this supply ship is similar to that of a 10,000-ton standard-class giant ship, such a giant ship will take into account the load capacity and economy, will not consider the speed, and can not be too modified, that is equivalent to covering the ears and stealing the bell, familiar with the ship will definitely feel that there is a problem, so a lot of power is wasted, and the tonnage of the supply is not high.

In China's dockyard, the current construction of 28,000 tons of supply ships, not only in terms of speed has reached the high speed of 27 knots, but also in terms of the type of supply, the tonnage of the supply, far higher than this one supply ship, that is the future, following the ocean fleet, and even the real supply ships of the aircraft carrier task force, as long as there are 4, the combat continuity of the aircraft carrier formation can be increased by more than 50%.

I am afraid that this is only a method of operation that can be possessed by an aircraft carrier battle group, the reason is very simple, in the era of battleships as capital ships, all those who followed the big fleet were all warships, and even on the battle line, they couldn't even go up for heavy cruises, not to mention civilian ships, no matter how good the supply ships were, the capital ships that chased the speed were on the main ships, but in order to load more things and have more efficiency, there was still no armor, such a ship, don't look at 28,000 tons, and if it ran into any warship, it would be unlucky.

That is, in the era of aircraft carriers, the two sides are hundreds of kilometers apart, there is enough strategic depth, as long as the supply ship has a certain amount of anti-aircraft firepower, there is the qualification of self-protection, the reason why the aircraft carrier has to be so big, on the one hand, is to accommodate more aircraft in the hangar, on the other hand, it is also necessary to prepare enough materials for the aircraft, bombs, torpedoes and the like, once these things are consumed, the aircraft carrier battle group must return, with the supply ship, the minimum endurance is much improved, and it is also suitable for the aircraft carrier battle group, Fight outside the zone.

These are the top secrets of the Chinese Navy, and even these supply ships are all single-line contacts, fighting on the outside line, far from Chinese waters, and their security is almost unprotected, so they can only rely on that layer of protection.

After the handover of the two sides, after the final basic determination, the supply began, 7 supply ships, quickly changed their appearance, in the position of the front and rear decks on both sides, a few more tower cranes and oil pipelines, a few according to the design, this supply ship, up to 28 submarines for comprehensive supply, however, at this time it is night, the current international high seas, in many senses, the management is not strict, they have at least more than 5 hours of time, so, Deng Jieqian did not choose a fast supply, It's a comprehensive, highest-standard supply.

Compared with rapid replenishment, standardized replenishment takes longer, but can effectively improve the combat capability of the fleet, this supply, in addition to weapons, torpedoes and supplies and other basic aspects of supply, more is to check the situation of the entire fleet, such as diesel units, batteries, and even will clean up the submarine, this cleaning is mainly carried out by underwater frogmen, but also with the help of some machines, it is better to enter the submarine dock, but it can allow the submarine to minimize the damage caused by the voyage, Half of the resupply at once, 2 and a half hours at a time, once the resupply is complete, all the submarines will be restored to their maximum effectiveness.

Deng Jieqian sent half of the ships to guard 5 nautical miles away to prevent uninvited guests from entering the supply site during the supply period, and at the same time of supply, up to 2.5 hours, half of the ships will be on guard on the outside, and the ships to be supplied will be idle, except for a small number of necessary personnel on duty, the rest will enter the supply ship.

This more professional supply ship, in addition to the supply facilities, there are also some entertainment equipment, mostly for the long-term combat mission of the fighters to relax, surface ships are a little bit better, submarines such an underwater ship, even if it is not sailing underwater, even if the small space is on the water, there is also a bit of stuffiness, etc., although the crew has received professional training, but then this opportunity to relax, it can be regarded as laying the foundation for the next war in the North Sea.

The North Atlantic breeze blows gently, each supply ship is connected to two or three submarines, professional oil pipelines inject oil into the submarine at a rate of 3 tons per minute, most submarines only have about a quarter of the oil, at most more than an hour, you can complete the refueling operation, on the other hand, a warehouse of the submarine was opened, a torpedo, was hoisted into the submarine by a crane, this is the largest, but also the most critical supply, submarine attack power, almost all from torpedoes, only enough torpedoes, In order to be able to maximize the effectiveness of the submarine.

Because of the relationship between training and combat, most submarines have less than half of the torpedoes, and to a certain extent, they can no longer give full play to the maximum effect of submarines.

Underwater, at least 200 frogmen are doing underwater clean-up operations, they are holding portable tools to clean up plankton, and they have carried out a cleaning work on the plankton attached to the submarine in the thousands of miles of sea to ensure that the bottom of the submarine in the future is clean.

Because of the excellent location selected, everything was quite smooth in the entire replenishment operation, up to 5 hours of replenishment, and there was no problem, after completing all the replenishment operations, 7 supply ships turned and left, these submarines carried out a series of replenishment, from the exhaustion of thousands of kilometers of the ocean, to the strength after the replenishment, Deng Jieqian ordered the last inspection of all units of the submarine, and found that there was no problem, the sky was close to dawn, they were in the supply area, after staying for 7 hours, Headfully into the Atlantic, aiming north, the North Atlantic route connecting the United States and the United Kingdom.
