The Rise of the Empire
Chapter 2875： Intelligence War One
Betty dared to propose intercepting the American transport fleet, not only because the Japanese combined fleet is strong enough, but also because the British intelligence network is indeed powerful. Although the British Empire has fallen, the once powerful fleet has fallen into the sand. However, the war wisdom of the British Empire has survived for hundreds of years. In the new era, when the British can no longer control everything, the British invest more in intelligence and have new developments! The Pacific War was also a test of the new British intelligence system.
"The Americans are gathering their transport fleet again." Standing on the bridge, Captain William of the Flying Fish used a telescope to observe the US transport fleet on the sea in the distance. At this time, in the A35 sea area marked on the map, the United States The navy once again gathered a large number of transport ships, and then unified cover by the convoy fleet. Then directly diagonally across half of the Pacific Ocean sent a large amount of supplies to the front lines of New Guinea and Bismarck.
In order to find out information about the assembly time, sailing time, and route of the American transport fleet, the British intelligence service also cast a large net on the ocean. Taking into account the current relationship between Britain and the United States, it is naturally impossible for the British to use merchant ships with the British flag to track the American fleet, so the method they adopted is to use merchant ships registered in third countries and then match them with the Royal Navy. The personnel observe the American transport fleet.
This observation requires great care. First of all, the reconnaissance ship must not get too close or stay for too long. There are more than ten destroyers or armed merchant ships outside the huge transport fleet. The U.S. Navy will never be merciless when it comes to suspected targets. These reconnaissance ships must maintain a certain distance and must not stay for too long at a time. Well, if it is this kind of relay stalking method, then the British must prepare a considerable number of reconnaissance ships, which is obviously not a good choice economically.
The British also have a way to deal with it. They can change their identity every time they come out. The ship is equipped with a large number of plates and paint. After completing an approaching reconnaissance, the British will try their best to camouflage the ship before conducting another reconnaissance, such as Speaking of Flying Fish, this time he is a fishing boat from Peru, and next time, he will become a transport ship from Chile. The crew will carefully repaint the ship and change some upper layers of the hull. Building shape. Think about it, the British navy can cosplay a merchant ship into a super fearless. How difficult can it be to add a few chimneys or remove some bridges?
In addition to conducting reconnaissance at the assembly location of the U.S. Navy, the British Navy will also arrange an "incidental encounter" with the U.S. transport fleet on the vast ocean! Of course, this kind of "incidental encounter" must also be dealt with seriously. For example, the location of the incidental encounter should be near the intersection of the US transportation fleet and the normal commercial route, and the "incidental" ships must also be "diversified." When implementing the tracking plan for the same transport fleet, the ships participating in the "random encounter" will come from France, Brazil, Turkey, or other countries that seem to have no connection.
Even so, about 40% of the ships participating in the investigation plan may not be able to find the target in the first time, because the Americans did not use the original commercial routes to transport materials, and they would choose some uncommon or even rare ones. The sea areas the ship passes through, these sea areas may be bad weather, may detour, but at least safe! As an American military officer who assisted maritime escorts said: "I would rather let 70 ships go round together, rather than lose a merchant ship by taking shortcuts!"
The Americans’ caution was rewarded. Because they chose relatively remote waters, the probability of the Japanese submarine force’s discovery of targets was greatly reduced, and the number of Japanese submarines and the command system were far inferior to the Germans, so they wanted to build a The network in the theater is very difficult. As a result, more than 30% of the transport fleet did not find a single Japanese submarine during the entire voyage.
Of course, Americans are definitely not sailing across the ocean. After all, the seemingly calm sea is actually not safe. Routes should always avoid those storm-prone areas or transit typhoons. In fact, there are not many large ships in this era. The average tonnage of the general ocean-going fleet is about 6,000 tons. Therefore, after avoiding the too remote seas and storm areas, the area that can be passed is relatively limited. The British approach is to look for the US transport fleet in these areas, and then based on the results of multiple tracking to sort out the US transport fleet's common routes.
After months of tracking and stalking, the British navy has gradually figured out the law of action of the American transport fleet, and it is on the basis of this intelligence that British talents are trying to persuade the Japanese to start the transportation line of the U.S. Navy. .
"The assembly time of the U.S. fleet can take about 6 to 8 hours depending on the size of the fleet. Before the fleet sails from ports in the United States to the target assembly area, their radio communication is kept open. In other words, if we compare If you are close, you can use radio lateral technology to detect the position of the US fleet."
"After completing the assembly and entering the route~www.novelhall.com~ Although the Americans tried their best to keep the radio silent, in some low-frequency bands, the Americans still maintain regular communication. This contact cycle is about 6 hours, according to the wavelength To calculate, it should be long-distance long-wave communication, and the content of the report should also be about the fleet's navigation."
"The U.S. fleet's maritime voyage time varies according to the assembly point and destination location. It takes about 150 hours from assembly point A to target A1. It takes about 165 hours from B to B1, and from assembly point C. It takes 170 hours to reach C1 and 160 hours to reach C2."
"The U.S. Navy seems to be adhering to the principle of randomness in the choice of routes. Before the transportation fleet leaves the port, they don't know which route will go after they merge. The only people who really know the route are the commander and guide of the **** fleet. After confluence, they will walk with the fleet, and in the process, the crew of the fleet do not know which route they are going to. Maybe only experienced crew can use simple equipment such as sextant to determine Get your approximate location. Considering that the Americans will arrange military personnel on every merchant ship, the idea of relying on merchant ships to get in and send reports is almost infeasible."
