Chapter 1733: The Dancer on the Tip of the Knife One

Chapter 1733 The dancer on the tip of the knife 1

"Let's get started!" Looking at his watch, it is now around 5 o'clock in the morning. According to the chart, the U1145 submarine is now approaching the sea 30 kilometers east of the Shetland Islands. This distance It was very well done. Under the cover of night, the observation points on the Shetland Islands and the patrol ships in the offshore would not go so far. At the same time, at this distance, the new antenna equipped with U145 can clearly receive and locate the radio communication situation on the Shetland Islands.

That's right, it's radio detection. In this age, who still uses eyes to detect? With the development of radio technology in this plane in an unscientific way, the Germans' radio detection and positioning technology has also increased. The submarine was in a semi-submerged state, and the huge antenna began to unfold, and it was aimed in the direction of the Shetland Islands.

Invisible radio waves were transmitted in the air, and soon the radio crew on U145 identified five huge signal transmitting stations. And mark them one by one on the chart. According to the channel analysis of the British Navy Fleet and the Naval Air Force, Doenitz quickly identified the identity of the other party, three of which were the signal stations of the British Royal Naval Air Force, and these signal stations should be used by the airport. The other one is the signal station of the British Grand Fleet, but it is different from that of the ordinary fleet. More like a liaison frequency for the British seaplane force.

"So, what we can confirm is that on the Shetland Islands, the UK has at least 3 airports used by normal aircraft and 1 airport for seaplanes?" Denitz asked, frowning.

"It should be like this. We and the previous batch of colleagues have been monitoring here for almost a week. The radio communication is very regular, and all of them are effective communications. Starting at 5 o'clock every morning, these radio communication base stations will start working. Their The main task is to guide the aircraft at the airport to dispatch. Most of these aircraft are twin-engine aircraft, mainly FB27 and O400. The main task should be detection and anti-submarine. There may be a big guy like V1500 among them. The radio equipment of the latter is more It is perfect, and it can be distinguished from the frequency and transmitter power." Lieutenant Preet, who was transferred from the headquarters of the High Seas Fleet in charge of radio work, said.

In fact, almost all the bombers of the British were shot down by the Germans. Therefore, the Germans are very clear about the radio communication equipment of the British bombers. Different bombers use different levels of radio stations. Generally, they are just navigation signals, while more complicated ones have transceiver functions. These radio stations are generally used on twin-engine bombers. Unlike the bombers of the British Army, sea bombers must be equipped with radio stations when performing missions, because the Army can Relying on landmarks to navigate, what about maritime patrol aircraft? Especially the North Sea, which is famous for its bad weather.... As for the radio level of the V1500 bomber, it has a higher level, with higher power and wider frequency band, and can even be used as an aviation base station to guide other aircraft.

According to the different communication methods of different transmitters, experienced radio personnel can obtain information by distinguishing signals, such as how many British bombers are in the airspace, their approximate positions, etc.

After a period of investigation, the data obtained by the German Navy is somewhat terrifying!

"According to our previous and current intelligence estimates, the number of twin-engine bombers in this sea area is about 120 or more, and the number of V1500 is about 30 or more. In addition, near the Shetland Islands, we can also I saw some DH9 and dromedary planes. If you count at least 40 seaplanes near the seaplane airport, the total number of planes is at least 270. To be honest, I really didn’t expect the British to come up with such a large The size of the fleet." Lieutenant Preet said.

"This does not include the British fleet in the Onik Islands. If my guess is correct, the Royal Navy's twin-engine and above fleets should all be here. The British aviation power in this area is simply terrifying!" Lieutenant Preet was drawing on the chart with a pencil in hand as he spoke. And marked the newly exposed radio transmitting stations on the chart one by one.

Not to say that the German High Seas Fleet can really number every British aircraft that appears here. During previous reconnaissance missions, other German submarines also wandered in the British blockade area, and they would record the number of the British aircraft. Patrol range, route and density. Then use these data to estimate the size and distribution of the British air force. Of course, there will be a price to be paid while obtaining a lot of information in this way. Two submarines were sunk and one was injured during the reconnaissance operation within a week.

"If it's sunny, such a sea and air warning network can be described as airtight. Fortunately, the situation in the sky over the North Sea in winter is changeable. Otherwise, our sea transportation situation will only be worse." Puli Lieutenant Te muttered to himself while recording the situation, but at this moment, he saw Captain Dönitz frowning and looking at a certain newly calibrated radio base station. Because this base station is too close to another base station that was calibrated an hour ago! In fact, if it is an airport communication or guidance radio station, it is impossible to set it so close, it is completely unnecessary.

"Is there a mistake in marking here?" Denitz asked, pointing to the map.

"Here, I am also a little confused. Judging from the frequency and password, it should belong to the Royal Naval Air Force, but as you said, the radio station here is very abnormal. We checked the radio frequency and transmission There is a 80% chance that the method is one. But there is indeed a deviation in the position." The lieutenant said seeing what Doenitz pointed out. This node casts all kinds of weirdness. If it is technically correct, can this radio communication node be movable?

"Come on, let's go and have a look!" Denitz said decisively, what's the matter? Now everyone uses radio positioning too much, have you forgotten the old methods of naval investigation? Since it is impossible to analyze the opponent's situation through the radio, let's go over and have a look. Although it has begun to dawn, the morning fog in the North Sea can still give the submarines these small targets very good cover conditions. According to the data from the side of the radio , the distance here is only about 35 kilometers from the submarine, so why not just walk over and have a look? What are you spending so much on? !

Dönitz and his colleagues quickly determined their position. At the same time, based on intelligence, they worked on the chart and drew a curved route. This route avoided areas frequently patrolled by the British and possible minefields. .
