"Course 225 degrees, speed 230 knots, altitude 7000 meters, distance 145 kilometers...... There are about 8 mainframes. Pen "Fun" Pavilion www.biquge.info"

Ingersoll and Turner learned through the radar that there were planes coming in the distance, which was undoubtedly the Germans, but what puzzled them was why the Germans launched at night? And this position is clearly a heavy bomber, what are the intentions of the moral army at night?

"They intend to reinforce the island of Sal? Say, airdrop troops? ”

"This ......" Turner hesitated, this is obviously contrary to common sense, the area of Sal Island is not large, and it is more likely that the airdrop will fall into the sea at night, "It is also possible that supplies or supplies are airdropped, after all, after several days, the German army is also consumed." ”

"Let the army on the island pay attention to ......" Ingersoll smiled bitterly, originally he thought that the 3rd Division would be the last straw to crush the German army after going up, but he didn't expect that although more than half of the chassis had been occupied, the Germans were still stubbornly resisting in the depths, because it was not easy to cover the naval guns in the center of the island, the 3rd Army Division advanced more slowly.

After a few minutes, the radar room continued to send an alarm: "The German course remains unchanged, it continues to fly towards the fleet, it is recommended to prepare air defense." ”

"Okay......" Turner sighed, "Level 1 Readiness ......"

"Does the plane need to take off to meet the enemy?"

"No need, it is difficult to take off and land safely if you can't find the enemy at night, so don't waste your efforts." Turner smiled wryly, "Don't expect too much from them. ”

This is a big truth, today alone, four planes fell into the sea because the pilot did not control it properly when landing, although the people were rescued, but the plane was absolutely finished, and it is better to expect these rookies to fight at night than to count on the Germans to be on the right track.

One staff officer muttered, "We have strict lighting control, and I don't believe the Germans can find us." ”

At this moment, Major Richter, who led the Night Stalker team, sneered: "Of course I can see your ......" The reason why he is so confident is entirely because the newly developed radar is generally installed on the aircraft: FuG-300. This is an air-to-sea scanning radar for detecting and locating surface ships, which is an upgrade of the FuG200Hohentwiel radar developed by C. Lorenz. The FuG200 has a detection range of about 120 kilometers at an altitude of 5,000 meters, and the Fw-200C was equipped with this radar and achieved the prestige of the Atlantic Condor.

However, the German side was very dissatisfied with the performance of this radar, because it was not only large in size, but also limited in search range and poor accuracy, but there was no good way, and after its invention in 1941, it could only be rotated on the original basis, until Hoffmann instructed the introduction of multi-cavity magnetrons from Japan.

The magnetron was introduced in 1921, but the multi-cavity high-energy magnetron was not invented until 1939 by Landall and Bout of the University of Birmingham in the United Kingdom, and soon after the invention of the British, the Japanese side also independently developed the technology. The starting point of the two sides was similar at first, but unlike the British side, which attached great importance to it, Japan basically ignored the invention and kept it on the shelf. It is not surprising that Japan has this attitude, and the Yagi antenna, invented by Professor Yagi, did not have any repercussions in Japan at all, and it was not until the Japanese army captured Singapore that the Yagi antenna was seen from the captured British facilities, and it was only then that it suddenly dawned on him.

Japan did not pay attention to it, Britain developed rapidly, more than a year later, due to the climax of the Battle of Britain, the British gave multi-cavity high-energy magnetron technology to the United States, at this time British products have been able to emit 3000MHz microwaves with a power of 10KW. The Japanese technology is still in the initial stage of 2KW, and then in 1941, the British invented the allogeneic coupling technology between the cavities of the multi-cavity magnetron, and the magnetron alternating teeth are bundled together to restrain in order to achieve stability, and the output power of 50KW at 3000MHz is obtained. For microwave radar, this power is sufficient, not only the size is greatly reduced, but also the weight is also much reduced. Japan, on the other hand, is still standing still – the gap between the two sides is now 25 times larger.

By August 1943, Germany had finally achieved mass production of multi-cavity high-energy magnetrons, reaching the level of Britain and the United States at the end of 1942, and successfully narrowing the technological gap between the two sides from four years to about half a year. The new air-to-sea radar of the FuG-300 type can achieve fleet detection at an altitude of more than 6000 meters above 200 meters, and the accuracy has increased by 1 order of magnitude.

Hoffmann also asked Lorenz to form a joint research group with another German radar technology specialty, Telefunken (called Hotline in the late Qing Dynasty and early Republic of China), to explore research on other types of radar. Relying on the technology of multi-cavity high-energy magnetron, Telefunken has also successfully developed the FuG-312 radar. Unlike Lorenz's products, Telefunken's products are mainly used for air-to-air detection of night fighters, which can detect large targets such as the B-29 at a range of 8 kilometers or small targets such as the P51 at a range of 5 kilometers, with a positioning accuracy of more than 200 meters - completely within the visual observation range of the pilot.

After the failure of the US daytime strategic air raid, the British side was unwilling to accept defeat and sent Lancaster bombers to continue to carry out night air raids, but they were often shot down by German night fighters equipped with FuG-312 radars, and the losses were very large, and later even night air raids could only be stopped.

The current Night Stalkers are equipped with these two latest models of radar, but Richter is obviously overthinking, the US military has no intention of sending fighter jets to intercept it, and simply thinks that the Germans will not be able to detect it.

"Find the main force of the US military...... Obediently, so many ships. ”

Richter was satisfied: "The units pay attention, keep the course unchanged, drop the altitude to 6000 meters, and prepare to open the mammoth system. ”

The Mammoth is their name for the large infrared irradiator, and this huge searchlight makes the Night Stalkers distinctly different from other aircraft, dazzling during the day and at night...... Hey, infrared is not visible!

Since the Germans did not drop bombs or flares, the anti-aircraft guns on the American destroyers and cruisers tacitly agreed not to fire, so as not to expose their positions by the fire, but they did not know that the German planes above had quietly begun to scan the American warships below with the mammoth system.

Watching the German planes flying overhead, dropping neither bombs nor flares, everyone wondered: these stupid birds above can't find us, right?

Turner instructed the ships to fire all their firepower if the German planes were lowered to 3,000 meters in an effort to shoot down the daring planes.

"Found it, sir, the number 3 saw a light aircraft carrier......"

Richter nodded with satisfaction: "Very good, let him come first." ”

The No. 3 plane skillfully descended in altitude, and the US radar soldier stared at the screen, watching the plane descend to 5,000 meters and not moving, not only secretly thinking: What can you see clearly at 5,000 meters? Let's obediently go down and wait for the anti-aircraft guns to greet you. Where did he think that the No. 3 aircraft had firmly locked on the USS Midway (Casablanca-class escort carrier) with the Mammoth.

"Go, baby!" With a muttered voice from the operator, an Hs-393 detached from the hook and began to flutter down, the small lights on the wingtips flashed, especially clear in the night, the guidance head in the front of the missile was equipped with a passive infrared detector called "Kiel", which was developed by Zeiss, weighs 19 kg, and has a maximum design detection range of 2km, which can detect the radiation signal emitted by the exhaust gases of the ship's flue, and its core sensitive element is a lead sulfide detector with a diameter of 12 cm.

When falling from an altitude of 6,000 meters, the infrared guidance head is not functional, and now the operator relies on the mammoth system with wingtip lights to correct the course of the missile, so that it can fly to the target position, and now the Hs-393 is completely controlled by wire, and there is no fear that the enemy will interfere with the control of the model.

"Good, keep the altitude, keep the distance ......" Subsequently, the 4th, 5th, and 8th units all found their targets, and similarly fired an Hs-393 and threw it down.

Looking at more and more shining things in the air, the ships below instinctively felt that something was wrong, and Turner also had a vague sense of uneasiness, and immediately approved anti-aircraft fire to return fire, but this was useless, on the contrary, after the anti-aircraft fire was fired, its temperature was higher, and the thermal radiation effect was more prominent.

When the system indicates that the missile is less than 2 kilometers away from the target, the control sergeant prays secretly, then activates the infrared seeker and subsequently cuts the wire.

"Ah...... That thing is coming at us...... Avoid, quickly circumvent ......"

Unfortunately, no matter how the Midway dodged left and right, the bombs overhead seemed to be fascinated, and the attitude could be adjusted according to the position of the warship, compared to the warship's painstaking maneuvering, Hs-393 only needed to be gently adjusted by attitude, and now the passive infrared detector of "Kiel" was firmly focused on the thermal radiation near the flue of the Midway—the faster the speed, the greater the amount of radiation.

With a "boom", the missile finally succeeded in penetrating the warship, and the huge weight impact force of more than 700 kilograms plus nearly 400 kilograms of explosives (equivalent to 500 kilograms of aerial bombs) exploded violently, and the death sentence of the escort aircraft carrier was directly pronounced.

Since then, such cases have been repeated many times......

8 Me-264s carried a total of 32 Hs-393s, although only 10 successfully hit the target in the end, with a hit rate of less than a third, but the results were extremely brilliant, 4 escort aircraft carriers, 2 cargo ships, 1 oil tanker were blown up and sunk, and even the battleships Iowa and New Jersey also ate 2.

When the Night Owl team sailed away contentedly, there were still traces of the tanker burning on the sea...... (To be continued.) )
