For Marshal Count Tirpitz, submarines were no strangers. www.biquge.infoIn 1906, the Germania shipyard built its first submarine, codenamed U-1.

It's just that submarines in this era have slow speed and short endurance, so they can only be used as a weapon for coastal defense. The major naval powers also do not attach importance to the development of submarines at all, believing that they are just weapons used by weak and small countries for sneak attacks. Even within the German Navy, submarines were not taken seriously. Especially when the German Navy was using more and more large surface warships, almost everyone was keen to build large surface warships, and they simply scoffed at submarines, which could only hide under water and carry out sneak attacks.

Marshal Count Tirpitz was also affected in this regard. If it weren't for Qin Tian, the person who used the submarine as a secret weapon was Qin Tian, he would have scolded him a long time ago. However, Qin Tian's identity and status are different, and Qin Tian has played a great role in promoting the development of the German Navy. This also made Marshal Count Tirpitz have nothing to say. At the same time, he couldn't help but guess in his heart, could it be that the submarine has other potentials that he didn't see?

"Your Excellency, that's right, the secret weapon I'm talking about is the submarine. However, the submarine in front of you is not a rudimentary submarine like the U-1 submarine, but a powerful submarine that can really be used in real combat. I assure you that if the German Navy could have a powerful underwater submarine force, it would be a surprise for us. Qin Tian looked very confident.

Marshal Count Tirpitz couldn't help frowning, the submarine in front of him was indeed different from the U-1 submarine, not only larger in size, but also more beautiful in shape. That's right, it's beautiful. Compared to this submarine, the U-1 submarine is simply an ugly duckling.

"Mr. Holland, introduce this powerful submarine to the Lord of the Navy!" Qin Tian said to an old man.

This old man is the famous John? Holland, the first person in the world to build a submarine capable of conducting real combat. Although he was already in his sixties, Qin Tian still invited him out of the mountain. Of course, really let John? A big reason why Holland was willing to help Germany build submarines was because of John? Holland is Irish. The Irish have always struggled for independence. Qin Tian to John? Holland assured that if Germany could defeat Britain in a future war, he would support Irish independence. So, John? Holland will do his best to help Germany in this regard.

Coupled with Qin Tian's unique insights in this regard, the German shipyard was able to build submarines that were ahead of this era.

"Yes, Your Highness the Crown Prince." John? Horan nodded.

"This is a brand new submarine designed and built, and His Royal Highness the Crown Prince named it the U-100 class submarine. This submarine, with a surface displacement of 328 tons and an underwater displacement of 279 tons, is 42.7 meters long, 4 meters wide, 8.6 meters high, and has a draft of 3.9 meters. The surface range is 3100 nautical miles, the underwater range is 43 nautical miles, and the maximum depth of the dive is 100 meters. The armament consisted of three 533-mm torpedo tubes, one in the front and one in the rear. In addition, six torpedoes were stored in the ammunition compartment inside the submarine, for a total of nine torpedoes. In front of the submarine's pressure-resistant shell, there is also a 75-mm naval gun with a hundred rounds of ammunition. "John? Holland said proudly.

Indeed, from these data, it can be seen that the U-100 class submarines are very advanced in performance, not only greatly surpassing the U-1 submarine built by Germany itself, but also surpassing the submarines built by other countries in the world.

"Your Excellency, the performance of this submarine is undoubtedly excellent. In particular, the strong endurance is enough to drive from Germany to the east coast of the United States. In the event of a war, the entire eastern Atlantic will become a hunting area for our submarines. At that time, whether it is the enemy's warships or other ships, they will be under the threat of our submarines. If we can equip hundreds of such submarines, it will be enough to strangle the sea transport lines of the British. If we cut off the sea lines of the British Isles, the British would be dead. Qin Tian said.

Marshal Count Tirpitz nodded. Although he thinks that submarine sneak attacks are a very ungentlemanly way of fighting. However, in war, it is possible to use any means that can be used at all costs. As long as you can defeat the enemy, any tactic is fine.

"Your Highness, this submarine is indeed very good. Still, I think that surface warships are the guarantee of victory. Marshal Count Tirpitz said.

"Of course, submarines can't decide the outcome of a naval battle. This is because submarines are sabotage weapons, and surface warships are control weapons. Our submarines are mainly used to strike at the sea transport lines of the British, as well as to sneak up on the main fleet of the British, to reduce the pressure on the surface fleet. Qin Tian said.

Marshal Count Tirpitz agreed. Although, there are certain doubts about the real combat power of submarines, Marshal Count Tirpitz is not averse to the purchase of submarines.

"Your Excellency, in order to fully exert the combat effectiveness of these submarines, I have come up with a tactic. I'll call it the 'wolf pack' tactic. That is, several or a dozen submarines, ambushing the enemy's fleet or fleet, launching a sneak attack. I think this will undoubtedly be catastrophic for the enemy. It's even better if it's at night. I don't think any fleet or fleet can escape this tactic. When the time comes, they will definitely pay an extremely heavy price. Qin Tian said with a smile.

After Marshal Tirpitz listened to Qin Tian's introduction, he couldn't help but feel chills all over his body. He had to admit that this was undoubtedly an extremely vicious tactic, which could give full play to the advantages of submarines. Of course, it would be nice that this tactic was in the hands of the German Navy. The enemy will suffer heavy losses under the blow of such tactics of theirs.

"Your Highness, this tactic is really good. It seems that the submarine is a weapon that really has a lot to offer! "Marshal Count Tirpitz was greatly satisfied.

Later, Marshal Count Tirpitz returned to the Admiralty and, after consulting with other officials, decided to purchase fifty U-100-class submarines. If there were subsequent modifications, fifty more would be procured, bringing the number of submarines in the German Navy to a hundred.

Qin Tian stayed at the Deutsche Shipyard and Johann? Holland discusses the issue of an improved version of the submarine.
