Chapter 1520: Modify route

The first step of wolf pack tactics is to use the submarines distributed on the sea to discover the enemy's transport fleet.
The breadth of the sea is unimaginable. For example, even in later generations, it is difficult to find the enemy's aircraft carrier formation. In this era, it is also difficult to find a transport fleet.
Therefore, it is necessary to engage in submarine sea tactics, arrange some submarines to patrol the other side's possible passage, once found, immediately notify the other submarines, and everyone go up and fight together!
At this time, under the telegram of the U-107 submarine, five or six nearby submarines were hurriedly rushing towards the direction it reported.
The Bering Sea, the waters near Attu Island.
"The Soviets are really smart, and made most of our submarines empty." On the U-107 submarine, captain Gunter Heisler said.
The Arctic route is still used by the Soviets. After all, this is the route that can support them most effectively, and the only route is the Bering Strait.
The Soviets placed most of the limited anti-submarine ships near the Bering Strait, and some anti-submarine aircraft were also waiting nearby with anti-submarine bombs, and they were able to get help from US anti-submarine aircraft at any time.
In this case, the danger of German submarines going to the Bering Strait to attack is greatly increased. Therefore, they can only retreat and patrol the Bering Sea in search of traces of the fleet.
After starting from the west coast of the United States, they need to cross the Aleutian Islands. Generally speaking, crossing from the easternmost island of Unimak is the most economical route, but the Soviets went around a big circle and bypassed the most of the islands. To the west, go back again.
Such a circumnavigation is very particular, and the main German submarine, that is, the submarine patrolling the eastern part of the Bering Sea, is bypassed.
The U-107 submarine also discovered this formation when cruising to the east of the Bering Sea and passing near Attu Island.
At this moment, Heisler was looking at the fleet in the periscope.
Many cargo ships are brand-new. This is a freewheel manufactured by the United States in accordance with industrial standards. It has a displacement of 7,000 tons and a speed of only a dozen knots. Its biggest feature is assembly line production, which is very fast.
Throughout World War II, the United States built nearly three thousand freewheels in 18 docks, fully demonstrating the American industrial heritage.
And now, no effort is spared to support the Soviet Union. If the United States did not give the Soviet Union blood, the Soviet Union would definitely be defeated. Therefore, the United States supports the Soviet Union's Liberty Ship, at every turn, there are dozens of ships.
The current fleet is composed of more than 30 freewheels, vast and mighty.
At the same time, in order to protect this fleet, the Soviet Union also used six warships to the entire formation.
At the forefront is the Wrath-class destroyer Vigilance. This destroyer with a displacement of more than 2,000 tons is the home of the Soviet Far East Fleet. This warship is also the backbone of the Soviet Navy. Nearly 30 ships were built before and after. The amount is large.
Two steam engines of 25,000 horsepower can make the entire warship reach a high speed of 40 knots. Under normal conditions, its cruising speed is about 15 knots. Now it is sailing slowly at 10 knots in order to Able to be consistent with the cargo ships.
On the bridge, the bearded Captain Boris is carefully observing the sea with a telescope.
"Is there any discovery in the sonar room?" Boris asked.
This Rage-class destroyer originally had no submarine detection equipment, but now their main task is anti-submarine. Therefore, in the recent period, these warships have installed submarine detectors provided by the United States.
Although they took a new route by detour, Boris was still very careful. For him, delivering the entire cargo ship safely to the destination was his most difficult task.
"No, everything is normal under the water." First officer Isakov on the side said: "Captain, you are too careful. There should be nothing in this sea area. Our biggest threat is the Arctic route after the Bering Strait. ."
Since the first attack, almost every time they were attacked was on the Arctic route, so, according to the theory, they didn't need to detour at all, Isakov was very puzzled.
"Yes, but we won't travel the Bering Strait this time." Until now, Boris finally revealed the most confidential information: "We no longer take the Arctic route. For maximum safety, we will Continue to sail west, unload the cargo in the Soviet port in the Far East, and then transport our supplies by rail."
The Arctic route is too dangerous. Although Soviet crews are not afraid of sacrifice, they must face the reality that the losses on the Arctic route are too great for them to bear, so they can no longer take risks~www .EbookFREE.me~Transport materials directly to the Far East and then transport them by rail!
railway? Hearing what he said, Isakov opened his mouth suddenly: "This is all right? The Far East Railway is already quite heavy, and there is no extra capacity to transport so many materials!"
Now, the Far East is the Soviet rear. After several wars, the Western Front suffered heavy losses. The Soviet Union has continuously mobilized troops on the Eastern Front.
This has already overwhelmed the railways in the Far East. So many materials can only be passed by sea and by rail, which is simply impossible.
"This does not require us to worry about it. In order to avoid being discovered, we need to keep it secret." Boris said: "After we passed through the southern waters of the Kamchatka Peninsula, we headed north into the Sea of ​​Okhotsk, and then crossed the Tatar Strait. Pass, arrive at the Soviet port."
This route is still a long detour. It is the nearest to go directly to the strait in the northern part of Hokkaido, but it may be discovered by the islanders. Therefore, in order to keep it secret, they decided to trouble.
They have avoided most of the threats on the route like this. The huge German submarines set up ambushes in the Bering Sea. They were destined to wait in vain. If it weren't for U-107, they might have found nothing.
However, the Soviets were even more unfortunate. If they knew that the Germans had established a submarine base on a small island in northern Hokkaido, I am afraid the Soviets would not choose this Far East route anyway.
This is simply throwing yourself into the net, looking for hardship.
In the middle of the formation, on a free ship, a sailor was lying on the side of the ship, looking at the distant sea with a high-power maritime telescope.
They have been frightened by the German submarine, and as long as they are idle and bored crew members, they will observe the sea as watchers.
