U-boats, wolves at the bottom of the sea. Due to the mental labor of Karl Dönitz, who had been a submarine captain and was captured during World War I, in the prisoner of war camp, the wolf pack tactics are now relatively complete. This, combined with the fact that Germany is now temporarily more advanced than other countries' submarine technology, the snorkel, makes German submarines equally swift and deadly underwater. But the technology, developed by the Dutch, was tested on only a dozen submarines, including Major Pullin's U-47 7B submarine.

But at the same time, after the submarine rushed to turn on the diesel engine underwater, the soldiers on the submarine had to endure the invasion of exhaust gases, and at the moment of shutting down, they had to endure an ultra-low pressure, and they had to envy the submariners' eardrums were very strong, old and strong.

In addition, the British have now developed a more successful hydrophone and passive sonar, which has forced the wolves at the bottom of the sea to take greater risks.

There were more than 100 submarines out on interdiction missions, divided into two groups, east and west, with the east responsible for blocking any enemy warships that might enter the English Channel from the East English Channel, and the western one responsible for the Brest-Plymouth blockade line to block British warships.

This time, Raeder played the old game -- the "Graf Zeppelin" aircraft carrier, which had just been launched, the "Bismarck" and "Tirpitz" two "Bismarck"-class sister ships, and some heavy and light cruisers responsible for escort missions. Their task was to support submarines in the direction of the St. George Strait.

The main reason is that the submarines of the West are mainly the early models of the obsolete Type 2 and Type 7, and in comparison, the combat effectiveness of these submarines is higher than that of the later models of the Type 7 and Type 9 in the East.

The design and construction of the "Graf Zeppelin" was mainly based on the experience of Japan and the United States in renovating aircraft carriers in the twenties and thirties, and the aircraft carrier still retains 280 mm heavy guns and 128 mm twin secondary guns. So the reserves of carrier-based aircraft dropped to 12 carrier-based fighters and 30 carrier-based attack aircraft (the Ju-87T can carry not only bombs but also torpedoes), Ji Feng thinks that these guns are flashy, and thinks that it may be better to dismantle these guns. But Raeder still insisted that it was useful to keep these main guns, and Ji Feng just thought that these guns were waste wood.

So the two became the "second general" of the Admiralty, just a marshal and a generalissimo. Raeder said that if the battle showed that the guns were very wasteful, he agreed to dismantle them, and also took out a 1916 Louis XIII, saying that if the tonnage of the capital ship was sunk more than 100,000 tons (based on the standard tonnage), the Führer would open the bottle himself.

You must know that more than 200,000 tons means sinking at least five warships or aircraft carriers with a displacement of more than 20,000 tons, or heavy cruisers or other capital ships, during this period, light cruisers and destroyers, etc., are not tonnage at all, in fact, the Royal Navy has a large number of destroyers, as far as the number of 39 years is concerned, there are at least 300 destroyers or submarine hunters of various types.

Raeder made a lot of money no matter what, and even if he lost the bet, he could sink a capital ship of tens of thousands of tons. The main guns of the Bismarck may not be very lethal to the enemy, but the lethality of Zeppelin's carrier-based aircraft should not be underestimated. The Pacific War was actually a duel between aircraft carriers [Of course, the last duel of battleships against the battle line took place in the Surigao Strait in Reytep Bay. 6 battleships and 8 cruisers under the command of Admiral Aldendorf of the U.S. Army (including the USS Maryland and USS California, which sank in Pearl Harbor. The rebuilt battleship was swift and full of lethality. So that the Southern Task Force lost two battleships (the two sister ships "Yamashiro" and "Fuso"), a heavy cruiser (an aviation cruiser, with carrier-based aircraft...... And a number of destroyers (only four), the commander of the Southern Task Force, Vice Admiral Shoji Nishimura, sank along with his flagship "Yamashiro". In this battle, the Southern Task Force was completely annihilated. (The "Yamashiro" was the first of seven warships to be built during the Shosho era, and was planned to be built in 1911)] Japanese and American aircraft carriers continued to sink and repair, and battleships faded out of naval warfare.

This deal was very valuable to both Ji Feng himself and the Third German Reich. This method of allowing naval officers and men to bravely kill the enemy was used by Taizu at some point.

The periscope on the submarine generally came out of the water, and the main reason was that the German submarine had a radio antenna installed on the periscope, which was able to conduct short-wave communication between submarines and receive orders from the general command of the submarine. Thanks to the second super-encryption of the Enigma cipher machine, the British computer is now unable to decipher the code. This, of course, is excellent for submariners.

※※※

Major Günter Prin lazily placed his arms on the two grips of the periscope and observed the outside world by rotating his body. I have to say that this captain who likes to smoke small cigars still has a hand in combat. At least for the current submarine ace, his comprehensive ratio is the highest.

Suddenly, the sonar unit reported: "Azimuth 005, long distance, battleship, a large wave of propellers is approaching at high speed!" "Now Pullin is met by the British ** ships that have rushed from the St. George's Strait to support, among them there are many heavy battleships, and even a few aircraft carriers.

At least for the "Graf Zeppelin" to be careful, and for the two super-battleships (in the case of the current navies of the world) to strengthen air defense vigilance. News of the discovery of the British fleet was radioed to the other Deep-Sea Wolves, who had no snorkels and could only use electric motors to slowly seize advantageous torpedo firing positions. But for Pullin, a cutting-edge submarine, it was very simple to seize a favorable position.

Vice Admiral Günther Lütjans commanded the "Graf Zeppelin" task force, and although the entire fleet together was less than half the main force of the British Royal Navy, for Lütjans, submarines could be transformed into their own advantage.

※※※

Ji Feng equipped the "Graf Zeppelin" with sea-detection radar and anti-air detection radar, and the two battleships were equipped with sea-detection radar, fire control radar, and air defense radar. When Erich Raeder asked, Ji Feng said that it was given by an overseas supporter.

The sea and air detection radars are equipped with an effective range of more than 200 nautical miles, while the fire control radar is capable of hitting shells into a pickle jar at a distance of 10,000 meters. With these equipment, Lütjans can be described as full of confidence.

The wolves under the water are not so easy, they put the periscope to the minimum according to their own experience, so that they can do it without dragging the water marks (there is really a height, in fact, the upper end of the periscope is very thin, and the dragged water marks are very, very short). Calibrate the direction of the torpedo while communicating with a shortwave radio.

Thanks to communication and speed, Pulin is now like a fish in water.

The maximum detection distance of the hydrophone and passive sonar of the British destroyer is 8 nautical miles, and for various reasons, the effective detection range is 20 degrees from left to right in the forward direction, but the superior hydrophone of the submarine discovered the British ** ship when the two sides were 14 nautical miles apart. So the submarine began to change positions in an orderly manner.

The four torpedo firing hatches in front of the U-47 opened like ghosts, closing the silent navigation of the qiē power, making the cigar-like submarine look like a ghost. The four electric torpedoes in the torpedo tubes already had their own targets.

"NR.1-Torpedo-Rohreineinschloss!" With the report of the weapons officer (I called it so because he managed all the weapons, including torpedoes), Pling began to look for the second target.

……

Having locked on all the targets, the fleet went exactly into the maximum range of electric torpedoes. When he was in the right position, Prin gave the order to open fire.

(Torpedo No. 1, launch!) ）”

……

Outside the boat, a large bubble bubbles emerged from the hatch, which was the all-powerful compressed gas - not only capable of firing torpedoes, but also able to press them into the tank when there was no electricity in the battery, and to urgently dilute the carbon dioxide in the cabin.

※※※

The wolves under the water fired almost all the torpedoes at the same time, and most of the hundreds of torpedoes were electric, and because they were modified before the battle, the sound of these torpedoes was very small, at least the current British hydrophones could not detect it, even if they entered a range of a hundred meters.

For the sake of fairness in the cruise, all sunken tonnage will be divided equally between each submarine, and each crew will be given about a month off, during which time their submarines will be upgraded. When the time comes, countless submarines like the U-47 will appear in front of everyone.

By the time these submarines are converted to complete their cruises, the British will experience what is called egg pain.

Just as Purin was thinking about this, the weapons officer next to him just reminded that the torpedo should be hit, and before the words fell, the explosion of four torpedoes came.

Through the periscope, Prin saw two targets he had chosen, the "Nelson" and the "Barham", and the combined tonnage of the two warships even exceeded 80,000 tons. But it was clear that just two torpedoes could not send this behemoth to the bottom of the sea.

But before Prin could be pleased, three shells of more than 127 mm smashed next to his U-47 and U-331. Without panic, Prin ordered to dive to a safe depth to load the torpedo, which was clearly a gradual shelling without an accurate target.

※※※

The target of the U-331 was the battleship "Barham", all four torpedoes were aimed at the same position, and even the advance was calculated.

Four 1,600-pound heavy torpedo warheads reached 500 kilograms, so that even if the armor of a torpedo was not bad after a hit, it would be enough to choke.

The Queen Elizabeth-class battleship "Barham" was obviously overwhelmed, and after hitting four torpedoes, the entire steel structure could no longer support it, so it broke apart, and all the glory of the past became a distant memory. The St. George's cross flag on the bridge was still fluttering in the sea breeze, but the front of the battleship was broken and thousands of tons of seawater poured in instantly, and the entire front part was warped.

The back part is also flooding, but because the quality of the watertight bulkhead is not good, the entire rear part has even become a big hall. The sea water seemed to break through the bulkheads and ceilings as if they were unobstructed.

The battleship built during World War I became the personal record of the U-331, as neither of Prine's torpedoes could penetrate the heavy armor, but the four torpedoes fired by the U-331 made the battleship history.
