Chapter 2879: Intelligence War Five

"Sir, your black tea is ready. The best Darjeeling black tea." Al Khan from British India handed a cup of steaming black tea to Major Wintour.

"Well, yes, it is indeed Darjeeling black tea. It is not the tea powder normally rationed to the army." Major Wintour put down the binoculars in his hand, and did not forget to cover the lens before taking the black tea from the assistant.

"Captain Gwen, have our observations over the past few days come out?" Major Wintour said.

"Part of it has come out. The American replenishment operations can almost be described with mechanical precision. Every time, there will be 3 water replenishment boats dispatched. They all set off on fire at 6 o'clock in the morning, 7 o'clock in the morning. Depart on time at the time. The entire supply process will last about 15 hours. That is to say, at 10 o’clock in the evening, the three water supply boats will return to the base, and then they will probably rest for 3 to 5 days before proceeding to the next time. Replenishment operations, and in addition to the normal operation of the replenishment ship, every week, there will be a supply ship to deliver supplies and supplies to the US military on Christmas Island." Captain Gewen said.

"According to our estimation, the route of the large transport fleet will be no more than 3 hours away from Christmas Island. In theory, as long as we can keep an eye on the water supply ships on Christmas Island, we can find one with the reconnaissance capabilities of the Japanese fleet. It’s not a big problem to support the American transport fleet."

"There is a small airport and seaplane dock in the northeast of Christmas Island. The Americans obviously also consider the safety of the Christmas Island area, so there are also seaplanes patrolling during the day. This may be a problem for our ambush fleet. After all, if we arrive early and happen to be spotted by an American seaplane, then the American transport fleet is likely to escape."

"Before the fleet departs, the Americans' radio waves will indeed explode, and several observations show that their frequency band and duration are relatively fixed. From this perspective, their communication content should be formatted. We are completely The general situation of the American fleet can be inferred from the communication frequency and time of the Americans in different time periods. For example, before the fleet sails, the communication time is very short. It should be to confirm whether the transport fleet has arrived at the supply position, and then About 2 hours after the departure of the fleet, the communication time will be longer, which should be related to the coordination of replenishment information. After 12 hours, the communication frequency dropped rapidly, and it seems that the replenishment should be over and the replenishment fleet is ready to evacuate." Ge Wen Said the captain.

"Well, it seems that we have found a lot of information, so let's send the information when we contact the K4 submarine tonight. After all, we still need the K4 submarine to verify the accuracy of the relevant information." Wen Major Tour said,

"By the way, after completing the contact tonight, we need to conceal it for a while. Our recent radio communication has been a bit frequent. The security team has discovered the abnormality of the US garrison. We now need to transfer to Base 2. Don't forget before leaving. Erase all traces.” The major thought for a while to add.

In the evening, when Major Wintour’s team passed the relevant information to the K4 submarine, the giant whale hidden deep in the ocean also began to perform its own mission. They had to verify the accuracy of the information through personal observations. For example, just a few minutes ago, the K4 submarine just received a telegram from Major Wintour. It is said that tomorrow, a transport fleet will pass by near Christmas Island to receive supplies, and the K4 submarine will Determine the relevant situation based on intelligence and inference.

"First of all, according to intelligence, the other party's transport fleet will pass 80 kilometers with Christmas Island as its center. So the entire range should be like this." The captain first drew a circle on the map.

"Secondly, according to our weather forecast, there will be wind and waves in the western waters of Christmas Island tomorrow. This situation will be very unsuitable for resupply. Therefore, we think they should resupply on the east side." The large blue pencil on the side marked half of the circle. Crossed out.

"Third, considering our radio direction finding distance and the visibility distance of the US fleet. (That is, the distance to observe the smoke column of the US fleet through the periscope.) We can cover the entire area as long as we deploy at these points, the key is Which of these points should we choose?" The chief navigator marked several nodes on the chart with a red pencil.

"The last problem is very easy to solve. The major's team will send us a telegram in the early morning, and the content should be about the heading of the US water supply fleet and seaplanes. Based on this information, we should be able to determine the US fleet. The approximate location of the submarine.” The captain of the K4 submarine finally said.

In the end, the result of the second day was still acceptable to the British on the K4 submarine, although it was finally discovered that the American fleet was at least 7 hours behind the scheduled time, and according to the adventure, the British were in According to the results of observation on the water, the distance between the two parties may be more than 50 kilometers... However, it is acceptable to be able to "see" the other party when it is almost impossible to decipher the other party's telegram. After all, if the Japanese joint fleet is here, the fleet with a large number of surveillance aircraft and more systematic radio information processing capabilities wants to discover There is almost no problem with such a fleet, and even after considering the discovery of the opponent, it is possible to deploy in advance.

It is possible for the staff of the United States and Britain to deduce the approximate route and timetable of a U.S. transportation fleet if it is combined with other aspects of intelligence to dig deeper into the relevant information ~www.wuxiaspot.com~. There is a saying, telling rabbits not to eat grass from their nests. Although a key point in the British positioning of the American transport fleet is Christmas Island, it does not mean that the Japanese fleet will attack the American fleet near Christmas Island. After all, judging from the major’s telegram, the U.S. Navy has become wary, and the major wants to stay on the island for a while. Therefore, it is necessary to remove suspicions as much as possible.

And if you take action near Christmas Island, you must also be careful with Christmas Island’s own reconnaissance forces, such as the seaplane and radio direction finding devices deployed on Christmas Island! The special frequency band low-power radio carried by the major may not be discovered in the first time when it is sent by special methods (for example, if a telegram is divided into several segments and sent in different frequency bands, then each piece of information is The transmission time is very short, and it is difficult for the opponent to catch it.) But the frequent transfers and contacts of the large fleet level are difficult to hide. As long as one is leaked, the result will be very bad!
