Chapter 1526： Aviation anti-submarine

"We supported the Soviet transport fleet and were attacked again." At the White House, Roosevelt was sitting in a wheelchair and meditating in front of a large-scale high-definition world map when he heard the words of his assistant.

When Marshall spoke, his face was expressionless and calm, but his fingers were trembling slightly, and his mood was definitely not calm at this time.

Cargo ships supporting the Soviet Union have been repeatedly attacked. This is no news, but this time is different from the past.

In the past, the attack was on the Arctic route, almost after the Bering Strait, the most dangerous sea area vulnerable to ambushes, but now?

In order to avoid an ambush on the Arctic route, this formation did not take the Arctic route. It planned to reach the Soviet port in the Far East to unload the cargo and then transport it by land.

As a result, they were suddenly attacked in the southern waters of the Kamchatka Peninsula, which completely broke their dreams, and the Far East route was not easy to follow!

what's next?

How to support the Soviet Union?

In particular, the most different from the past is that this time the number of submarines is quite huge.

"We have repeatedly studied the attacks on the Arctic route, and we can confirm that there are very few submarines on the Arctic route, no more than three submarines, or even one, because we have never seen two submarines. At the same time, because the opponent’s underwater navigation capabilities are particularly good, we think there may be three ships."

Marshall continued to analyze Roosevelt: "But in the southern part of the Kamchatka Peninsula, we encountered a large number of submarines. According to our estimation, there were about 20 submarines. They were like wolves. They came up to bite the cargo ship formation and served as **** missions. The warship was sunk in the first place."

A huge number of German submarines have appeared in the North Pacific region. This is definitely not good news for the United States.

Although up to now, these submarines have been attacking the formation of cargo ships assisting the Soviet Union, but who knows if they will come to fight the ambush of the US fleet?

Moreover, under such rampant submarine activities, they could no longer continue to transfuse blood to the Soviet Union, and the Soviets would definitely not be able to hold it.

"This is really bad news." He took a cigarette and continued: "It's simply impossible to go by land. We can't take a ferry in Alaska. We have to open up sea transportation."

In World War II, there was a feat of road transportation, that is, the huge fleet of cars on the Burma Highway, which supported the Chongqing government's battle, but how many kilometers was that?

If you go directly overland from the United States, across the Bering Strait, and transport to Moscow, you will have to cross more than half of the earth, and the journey will be more than ten times this. At least half of the entire fleet must be used to transport fuel, absolutely not. It might be done.

It cannot be carried by land, nor is air transport. The United States does not have enough transport aircraft, and air transport consumes no less resources than land.

Therefore, it has to be the waterway, and the sea transportation line needs to be opened up.

"Moscow also meant that." Secretary of State Hull said: "The Soviets asked us to dispatch the navy to **** their cargo fleet."

The Soviet navy was weak and almost always belonged to the czarist era. The main fleet was no longer on the western front, and the Far East fleet simply couldn't. In this case, the Soviet Union could only turn to the United States for help.

Hearing this, Roosevelt frowned: "No, we simply don't have enough navy to open up this transportation line."

Now, the U.S. Navy has to clashed with the island navy. Seeing that the island navy will take root in the Hawaiian Islands, how can it be able to provide **** ships to the Soviet Union?

"No, we don't have that many warships." Roosevelt said: "The **** formation must be solved by the Soviet Navy itself."

If there is a battleship guarding the formation, the German submarine will have a lot of concerns. But how could the capital ship be provided to the Soviets? Who knows if it will be accidentally worn out? The United States can't afford it.

"We can provide the Soviets with ships, and we will provide as much as they sink." Roosevelt said, "This is our biggest bottom line."

In later generations, the German wolf pack tactics were eventually shattered by the Allies. As for the reasons, there are many arguments, such as the improvement of the Allied anti-submarine technology, such as the skill of their captains, etc., but there is a simple According to the calculation method, the United States has a strong industrial foundation, and more cargo ships are built than consumed, and the Americans can resist.

Now, the Americans can only use this method. With the start of the war machine, American industry has fully transformed into the wartime system. When the powerful industrial machine is started, it can be reproduced at any consumption.

U.S. suppliers of ships can provide as many new ones as they lose. This is already the maximum.

"No, not enough. If we only supply ships, we still can't avoid this ending." Admiral Nimitz said worriedly: "If we don't increase the anti-submarine force, we can only give prey to the Germans."

As a navy general, Admiral Nimitz is an expert.

"But we absolutely can't provide the Soviets with an **** fleetWe don't have that many troops." Roosevelt said.

"Yes, we can't provide an **** fleet, but we can provide aviation." Admiral Nimitz said: "We can provide professional anti-submarine aircraft to the Soviets. If deployed on the Kamchatka Peninsula, it can take care of nearby The sea within 500 kilometers."

The American technology is extremely advanced, and how to detect underwater submarines is also one of their focus. After research, they have developed a magnetic anomaly detector and equipped it on the PBY-5 "Catalina" seaplane.

Before the attack on Pearl Harbor, this system was tested. A PBY-5 took off from Rhode Island, detected the submarine, and successfully verified the magnetic anomaly detector system.

Later, the Naval Research Laboratory confirmed that the PBY-5 radar system can receive and transmit electromagnetic pulses without using a bulky auxiliary antenna system.

In addition to this magnetic anomaly detector system, there is also a sonar buoy.

Just like history, in 1941, the United States developed a sonar buoy, but it was carried by an airship. Even if the airship patrols the target, it does not have enough time and weapons to attack. This is just the beginning. , There is still some time before practicality.

In short, for the United States, the use of aircraft to anti-submarine is completely feasible.

"The Soviets simply don't have the right pilots to fly these equipment." Secretary of State Hull said to the side: "Their rookies all began to train on the Western Front after hurried training. If you want to anti-submarine, you need at least dozens of them. Members of the aircraft, they simply couldn’t find it.”

"You can send us." Nimitz said: "We have experienced crews. We simply pack them to Kamchatka with equipment and people. The Soviets will not refuse."
