Because of the harsh weather on this route, merchant ships rarely traveled, so that the Japanese could reduce the chance of being detected and achieve the suddenness of a sneak attack, and the Japanese also had an order to sink all the ships encountered on the route for secrecy.
-
The Japanese army should take the route of going northeast and then southeast, detouring through the Arctic Ocean and then going south, this route is windy and rough, which can paralyze the US military and make it think that the Japanese army will not launch a sneak attack, because the US reconnaissance planes in Midway Island and the South Asian Islands can easily photograph the shortcut from the Japanese islands to Pearl Harbor. The geography teacher said that the shortest distance between two points on the earth is a curve, because the earth is round.
-
The shortest route, the extension of which forms a closed circle, passes through the center of the earth, exactly dividing the earth in two. The straight line you are talking about should be the meridian, try to think about it, is the meridian longer?
Therefore, the Japanese army should take the route of going northeast and then southeast, and there is another consideration, that is, this route is windy and stormy, which can paralyze the American army and make it think that the Japanese army will not launch a sneak attack.

First of all, you have to understand: what does the great circle on the sphere mean?
The so-called great circle is the circle that passes through the center of the sphere. For example, the great circle of the earth has various meridian coils and the equator. It is conceivable that the Northern Hemisphere must first go northerly and then southerly to get from one place to another.
As for the Japanese army's choice of this route, there are the following considerations:
1: Short range. The time required is short, and the chance of being discovered by the US military is relatively small;
2: This line is consistent with the North Pacific Warm Current, which is smooth and smooth, saving fuel and saving time;
3: This line is windy and stormy, paralyzing the US army;
4: The Japanese submarine forces on this line have long been slightly superior to the US military in terms of tactics..
There are endless points, my knowledge is limited, forgive me! )

It can only be the USS Enterprise, an aircraft carrier of the United States, participated in almost all important operations of the US Navy in World War II, was repeatedly wounded, survived catastrophes, and was wounded at the most critical time of the war and prepared to single-handedly take on the Combined Fleet, and received numerous honors, so that the name of the Enterprise will remain forever.

A lot... During World War II, the Japanese thought that they could directly control the vast Pacific Ocean by destroying the living forces of the US Pacific Fleet, and at that time there were three aircraft carriers berthed at Pearl Harbor, but on the day of the sneak attack, none of them were in the harbor. The Japanese destroyed several battleships and a large number of aircraft.
After that, the United States, with its strong national strength, and aircraft carriers came out one by one like dumplings. It is estimated that there will be about 130 of them. Others were used to aid Britain in naval warfare.
Strong national strength is the foundation of war.

If we count from the Japanese attack on Pearl Harbor on December 7, 1941 to the surrender of Japan on August 15, 1945, the specific number of aircraft carriers built and launched by the United States is as follows:
22 aircraft carriers of the Essex-class fleet.
2 aircraft carriers of the Midway-class fleet.
9 Independence-class light aircraft carriers.
1 light aircraft carrier in Saiban.
There are 45 Borg-class escort aircraft carriers.
There are 18 Conmensment Beach class escort aircraft carriers.
50 Casablanca-class escort aircraft carriers.
There are 24 heavy fleet aircraft carriers, 10 light aircraft carriers, and 113 escort aircraft carriers, totaling 147 ships.
If we count from the outbreak of the German invasion of Poland on September 1, 1939, we should add the Yorktown-class large aircraft carrier Hornet, the escort aircraft carrier Long Beach, and the escort aircraft carrier Sangamon. then a total of 151 ships.
If we include the aircraft carriers that were basically built during World War II and launched shortly after Japan's surrender (in 1945), we should add two large aircraft carriers of the Essex class, one light aircraft carrier of the Cybon class, and one escort aircraft carrier of the Conmensgate Beach class.
To sum up, in a broad sense, the United States built a total of 27 large fleet aircraft carriers, 11 light aircraft carriers, and 117 escort aircraft carriers throughout World War II, a total of 155 aircraft carriers!
-
There are a total of 162 aircraft carriers, large and small.
Looking back at the history of naval warfare, aircraft carriers can be said to be the most high-profile protagonists in the Pacific theater of World War II. Starting with the Japanese Navy's attack on Pearl Harbor with six aircraft carriers, it went through the Battle of the Coral Sea, the Battle of Midway, the Battle of Guadalcanal, and the Battle of the Marianas. Until the effective combat effectiveness of the aircraft carriers of the Japanese Navy was completely destroyed during the Battle of Leyte Gulf, aircraft carriers appeared in each naval battle. >>>More
What is the theory upstairs At that time, the largest debtor of the United States was the United Kingdom, followed by France, that is to say, if Germany destroyed Britain and France, the United States would go bankrupt, at that time resources were tight, and the United States made a fortune by selling arms, but at that time, the war continued, and it was impossible to have full cash payment, so it could only be in debt, and at the beginning of World War II, Britain and France owed the United States more than 20 times more than Germany (I remember this number, only a little more) That is to say, the famine owed by World War I has not been paid off Therefore, the United States can only choose a position to stand on the side of Britain and France. There is also the fact that Hitler's goal was not to conquer the whole world, at least he did not mean to destroy Britain. Otherwise, Dunkirk would not have given the British a chance, and his goal was to capture France, stabilize Britain, and destroy the Soviet Union, so as to turn the whole of Eastern Europe into his own resource base. >>>More

The British invented, but they were all refitted, such as the first aircraft carrier "Fury", the American "Langley", and the "Hundred-Eyed Giant" were all converted with ironclad cruisers and merchant ships, and the first aircraft carrier completely designed in the true sense was the "Fengxiang" launched by Japan in 1922. >>>More
