Chapter 1693: Secret Stealth

In order to send such a huge number of iron lumps to the battlefield, it is impossible to rely on tanks to travel, from the hinterland of the United States to Vancouver on the west coast of Canada, at least four or five thousand kilometers away, even in later generations, in the eighties and nineties of the 20th century, the long-distance attack of tanks is also a very difficult thing, not to mention more than 5,000 kilometers, even if it is more than 2,000 kilometers of running, it is very rare, and long-term attacks will make the machinery damaged, and eventually fall short.

At the end of the 20th century, the mechanical level could not support such a large-scale long-distance attack, let alone the United States in this era, the Americans tried their best to reduce the range of tank travel as much as possible, and the entire Central Railway, including the Canadian side, was requisitioned by the Americans for 12 days. The United States has completed the transfer of 12,000 tanks from the hinterland of the United States to the Vancouver area, a huge journey of more than thousands of kilometers, a weight of millions of tons, and the tank itself alone may only be a few hundred thousand tons, but the tank is not only in itself, weapons and equipment, spare materials, and even personnel, all of which have been transported over, and the transportation capacity consumed is huge, and even once affected the entire American transportation network, and there were problems with raw materials and materials in some places, and even affected the economic structure of the United States.

The domestic railway network in the United States is very huge, but simply a mobilization of forces, in one region, to another region, this test is not the overall capacity, but the limit of the minimum capacity of a railway network, this point, the United States railway network compared with China, the difference is too far, some places are even double lines, the density of vehicles is not enough, the former is because the American railroad has been vacant, part of the old railway is still in the list of demolition, the latter, is because, the relationship between the operation map, The U.S. schedule is still in a relatively sparse stage, and the distance between one train and another train is at least 40 minutes or more, and most of them are more than an hour.

Railway operation diagram, is the basis of the safe operation of the railway, his density, represents the highest capacity of the railway, in principle, if there is, a few meters between the train and the train is also considered a safe distance, this is the ideal state, the maximum range of use of the railway, unless it is in the automatic control and locomotive performance to the highest degree, can stop the train at any time, and in the shortest time to react, so as to be able to achieve such a limit state.

At present, the distance between trains is more of a country, the essence of overall planning and control, the United States can only do the limit of 40 minutes apart, but China's timetable, the interval can be shortened to 5 minutes, or even 3 minutes, the shortest distance between the two trains, can be reduced to about 5 kilometers, this is the leading technology and calculation.

The use of a large number of computer systems, not only can accurately control the operation of the train, accurate to the second, but also can quickly respond to the problem of the train, train positioning technology and radio technology is the most developed China, has substantially solved this problem, this year, the train schedule interval again reduced by 5%, do not underestimate the 5%, which represents the entire Chinese railway capacity increased by about 5%, which is already a huge Chinese transport data, is already considerable, this improvement, At least in the tens of millions of tons, and possibly even to a height of 100 million tons.

The United States does not have computers, a lot of data, or in the degree of manual calculation, and even because there is no relationship between the three major projects, they can not coordinate some things, may also feel that there are still some omissions in the railway operation map, but they can't see where the problem is, after all, a running map spread over millions of square kilometers of land, if there is no omission at all, it is absolutely impossible, and only when the real calculation and experience exceed a certain level, can we find out this problem.

China is also like this, from the very beginning, laid a scientific foundation, from the National Railroad hired chief engineer, so that China's railways from the very beginning, has absorbed the experience of American railroad operation for decades, the addition of computers, and Yang Yuanzhao from the sporadic experience brought by later generations, so that China's railways have developed rapidly, has had the appearance of the end of the 20th century, in terms of floor area ratio, China's railway volume ratio and total transportation volume, is the same mileage of the United States railways more than 6 times, not to mention the total mileage of China's railways, It has long been quietly surpassed by the United States.

The railway network of the United States is also very developed, especially the east and west coasts, under the premise of the Pacific Railway, the volume of transportation is increasing, the United States for these tanks, did not hesitate to stop some passenger and freight transport, regardless of the cost, it took 12 days, at the speed of 10,000 tanks per day, to transport these tanks to Vancouver.

Before Vancouver, there was a huge railway, which could be used for tank transportation, so from the hinterland of the United States, to Vancouver, 12,000 vehicles were not left behind, got off from Vancouver, assembled a little in Vancouver, and then followed the highway in Vancouver, and continued to move forward, in order to meet the arrival of tanks, American sappers and construction teams have been working near Vancouver, reinforcing some roads that can be used, mainly some broken parts and bridges, which used to be only a few hundred kilograms, at most one or two tons of vehicles, But now the 25-ton tank has a huge pressure on most bridges.

Only reinforced bridges can allow tanks of about 25 tons to advance, and it is very difficult to enter the area north of Vancouver, there are no obvious roads here, and the roads built before to supplement the logistics of the American army are too simple for tanks of more than 20 tons, and some ordinary bridges cannot bear the weight of tanks, and even some places cannot use bridges, so they can only cross rivers.

From Vancouver to Juneau, hundreds or thousands of kilometers, almost pristine conditions, this is a new experience for the US military.

In order to ensure the safe progress of the tank team, there is a maintenance team composed of car repair experts with the tank unit, they carry enough parts, a little damage, will be repaired, even so, it took half a month to let about 8,000 of the 12,000 tanks come to the Juno line.

Spanning more than 1,000 kilometers, and most of them are relatively harsh environments, a series of rivers, mountains and swamps, etc., in these almost pristine land, the failure rate of tanks passing is quite high, 12,000 vehicles eventually only 8,000 arrived, the reason is very simple, there are failures along the way, those that can be repaired will be repaired, and those that cannot be repaired will be disassembled, especially the engine, the loss rate is the highest, and under such filling, almost 4,000 tanks are discarded, or completely abandon the result.

For the U.S. military, their purpose is very simple, must ensure that more than 8,000 tanks arrive at the front line of Juneau, only 8,000 tanks, in order to carry out a comprehensive attack on the entire Juno's front line, now there are only 8,000 vehicles, this is the most basic number, one-third of the abandonment, so that the U.S. military really recognizes that such a tank in the long-distance march in the weak link, it seems that in the future tank design, this needs to be strengthened, reliability, and the difficulty of repair, Adjustments must be made to increase the efficiency of repairs, perhaps in order to reduce losses.

In this long-distance march, the United States has gained a lot, and even some modifications to the future tank have new indicators, which will be clearly stated in the next generation of tank indicators, if at the same time, the performance of the tank engine can be improved, the next generation of tanks will reach a very high level of various performance indicators.

The Americans have gained a lot in this long-distance march, these are all later words, they must win this battle, time waits for no one, God knows if China will find out that their tanks are running long distances, and when the time comes, they will really equip the Japanese with a large number of bazookas, and when the time comes, even if they get more tanks, it will be useless.

In the past month, the U.S. military has not attacked, to replace it with the Chinese army, it will definitely be strange, will go to reconnoitre, but the Japanese point of view, it is only caused by their strength, they continue to hold, in their opinion, at most 4 months, Alaska will usher in winter, when the time comes, they are in a fixed position, even in a bunker, winter is coming, Alaska's winter is much better than Siberia's, in the fixed positions and camps, than the U.S. troops in the field, They will never be the first to withdraw from the war.

The Americans are very careful in their actions, and they are quite in place, especially in the vicinity of Juneau, even if they increase losses and reduce efficiency, they must travel day and night, in case they are discovered by the opponent, if they say, under ordinary circumstances, more than 8,000 tanks, or tanks strengthened by the Northwest engine, will be devastating for the Japanese defense line, although it will not completely crush the defense line of more than 4 million people at once, but destroy a three-third, that is no problem, 1.2 million losses, I'm afraid that Japan, which prides itself on bushido, will not be able to bear it, and may collapse and mutiny.

However, the Americans have calculated everything clearly, and they can avoid reconnaissance aircraft by traveling day and night, but one of the fatal shortcomings of tanks is the sound, which may be covered by various noises during the day, but at night, in the silence, this sound can be heard from a long distance, thousands of tanks, perhaps tens of kilometers or even hundreds of kilometers, can not hear the sound, until within 100 kilometers, even at night, it cannot be blocked, the most important thing is that Japan distributes special forces around to prevent a sneak attack by the US military, A special forces unit dispersed to a distance of 200 kilometers, in an accident, found traces of tanks.
