My German Empire

At this time, the tiger shark submarine who added the ammunition supplies and completed the ammunition material once again kill the US coastline.

"These idiots are really not long-lasting!" Krezimer, who is observing the distance in the distance, can't help but sigh.

It is not possible to say that it is completely long-term, and the channel has increased the destroyer of the patrol alert, but the number is not much, the distance between the destroyers is at least four or five kilometers. Of course, if the speed of the destroyer is sailing, the distance of the four or five kilometers is just four or five minutes.

And the freighter in the channel is still leisurely. This is to be replaced with a British transport fleet a few months, which will definitely change the speed and heading during the driving process, which is used to avoid the possible submarine attack. "Since you don't have a long memory, then give you a better class."

His percentage is in a prioritudinal covering a farther utensil ship. It is also a clever, this freighter is the only one in the five freighters transported by the Brooklyn Base. The four freighters in front of the two-year-old shovel, this freighter naturally did not dare to fight again, only to head to the Washington Navy factory, but the result was in halfway to meet the Tiger shark submarine in Krazzer.

"No. 5 Torpedo Preparation! Deep 7 meters!" Look at the water and speed of this ship, knowing that it is loaded, even if a torpedo can be easily set.

"Torpedo is ready!"

"emission!"

" ..." As the submarine slightly tremble, the sea water poured into the torpedo launcher.

Submarine underwater in the Second World War is mainly pneumatic (imbalance).

This emission method is to inject the high pressure gas into the emission tube in the torpedo, such as the inner and outer air pressure. When launching, the front sealing cover opened, the high pressure air was poured from the tail of the launch tube, and the torpedo was pushed out. The advantage of this approach is that the initial speed of the torpedoes is wide and widely applied, and there is no power mine and various equipment. However, the disadvantage is that the high pressure gas floods into the sea water to generate a large amount of bubbles to expose the submarine. To this end, engineers designed air recovery units, when torpedo travels to 3/4, the engineers are recycled, discharged to the inside of the potential, thereby avoiding a lot of bubbles.

Pushing the torpedo in the water, the deeper the seawater pressure is, the larger the internal and external pressure difference between the emission tube, so this method cannot be used in deep water regions, only suitable for depth of 80 to 100 meters or more.

The submarine submarines generally use balanced launch methods, and there are three operations. One is to first push the rod in the launch tube with high pressure air, and then the top rod will take the torpedo, and the torpedo does not need to contact water before coming out of the emission. The second is to use the torpedo self-motivation, first open the torpedo, wait until the inside and external pressure is balanced, the torpedone ignition propeller rotates yourself. The third, is also the most widely used emission mode, that is, injecting sea water, etc., the water pressure balance in the transmitting tube is pulled through high pressure air, and the water torpedo bottom piston is pressed by the piston to press the sea water to promote the torpedo launch.

The Tiger shark submarine uses this third method, and the torpedo launched the launch tube rushed to his goal in the corresponding water, and a white track is drawn on the sea.

"No. 5 fish ray is completed!"

Looking at the freight wheel that is still slowly swallowed in the vicinity, Krezmer knows that this torpedo will be hit. "Dump 30 meters, left to 15 degrees, speed 15!"

Several sailors on the freighter are smoking in the railing.

"It's really thrilling yesterday."

"Yeah, it's a little bit, even we have unlucky."

"It's a evil door, other vessels are fine, why do we turn thunder? Do you have any of the destroyers?"

"Who knows? Maybe it is a German mine look at our freighter?"

"These idiots,

"The president is the idiots, what are you doing in Europe?"

"Maybe it's like the German Royal Reserve, he wants to serve president."

"Continuous president, I think he is to be the emperor. If he dares to campaign, I would rather give him a vote to the monkey."

Everyone can't laugh, one person pops the smoke, and the eyes will not pay attention to a white track in the distance.

"Hey, you see, is it a dolphin? So fast?" He asked in a distance.

"Where?" Other people hoped in the direction he know. When you see what you are, a few people suddenly scared, the legs are soft, and the legs are almost sitting on the metal floor. "Fish, fish ... then, then ... That is a torpedo!"

Unfortunately, they are not a well-trained navy, just an ordinary people's boat, in the face of this sudden situation, a few people in the brain, can only look at the torpedo hull in the eyes.

"boom!"

The unlucky freighter fails to escape his fate and gathered with other four brothers.

The distant destroy operators noticed that the explosion here is taken along with the maximum horsepower. When it arrived, this freighter was seriously tilted, and it was obviously not long.

"Damn!" The destroyer captain Brady curse, hurry to call the destroyer to help; and he goes to chase the dead submarine.

In his awareness, even if German submarine is red, underwater speed is definitely not 10 knots. In this short a few minutes, it is not possible to run too far, his 30-speed destroyer will definitely be easy Chasing. Of course, the premise is that he can accurately judge the direction of German submarine escape. If it is not enough to compete, it is impossible to catch a submarine of different shipping.

The destroyer sharp shot cuts the spray, leaving the traces of its own speed on the water. On the bridge, a big deputy is a bit worried. "The captain, may be a German wolves? We ran to chase, will not ..." In case of several German submarines, from all directions, they launched fish thunder, then they are really inserted. .

Breddy nodded. "Let everyone go out to stare at the sea, be careful of the enemy's sneak attack." With his order, there is no mission, all the sailors are gathered to the side, and the eyes are wide and searched.

Soon the destroyer came to Brradi to think that it was a place where the German submarine launched the torpedo. "Saiting! What is wrong?"
