Sweden's Timro is a port city located in the southwest of the Gulf of Bothnia, the bloody World War I, the brutal World War II or the heart-wrenching World War III, the European continent has not affected this beautiful and quiet little place, thousands of Swedish residents who have lived here for generations live on timber and fishing, they enjoy a monotonous and peaceful life, the Gulf of Bothnia is basically frozen for five months a year is also a rare sea of war in this era.

About 60 kilometres from Timro, Edessa Airport was originally a small airport discovered and opened by flying enthusiasts, and was previously used only for small private jets until the summer of 1946, when the acquired Swedish Aircraft Joint Stock Company (Saab) bought it as a new aircraft proving ground, tripling in size and building a number of curved domed hangars and workshops near the runway. At first, Timro's residents only heard about the overall size and technical strength of the restructured Saab company, and soon they began to see a variety of aircraft in the nearby airspace, most of them new without propellers. According to past experience, the test flights of new aircraft have always attracted more or less attention from the outside world, but the war clash between the Eastern and Western camps has simply attracted the attention of the entire planet to the vast land of Eastern Europe. For a long time, the outsiders who came to Timro were Saab employees, pilots, pilots, and orderlies, and these people received enviable salaries, which made Timro's few taverns unprecedentedly popular, and the shopkeepers had money in their hands, and when the harbor thawed, they bought large barrels of good wine, and some bewitching women and men of all kinds also appeared on the streets of Timro. At this rate, Timro was able to become one of the most vibrant cities in central and eastern Sweden within a few years, but the good times were short-lived, and the pilots, pilots and service staff stopped visiting the taverns. The airport's connection to the outside world gradually fell to trucks that regularly came to buy fresh fish, and it was during this time that the frequency of planes in the nearby airspace increased significantly, and they were no longer satisfied with flying in a straight line, and residents continued to witness jets juggling in the air, such as diving down from a high altitude and pulling up quickly, or rolling and turning rapidly. On top of that, residents sometimes hear the faint sound of gunfire and explosions on cloudless days or nights, small details that are insignificant to most people, and a few veterans who have fought in Finland as volunteers are more sensitive to this, protesting to Saab representatives on the grounds that their safety is threatened, asking them to cancel weapons tests and reduce the number of flights around Saidsa, and when they find that the protests have failed, they write to the government.

In the spring of 1947, the Swedish Air Force decided to order Saab's newly developed "Black Wraith", a twin-engine jet fighter that was significantly different from the former Third Reich's air combat weapon M, and many details can be seen in the eyes of insiders in a typical German style, and in the confrontation exercise with the British-made "Vampire" jet fighter introduced by the Swedish Air Force years ago, the "Black Wraith" With excellent aerodynamic performance and the radar-cannon system imported from Erlikon, Switzerland, it has achieved an all-round overwhelming advantage. Since the prototypes had already made enough test flights and the Swedish Air Force was so pleased with their performance, the first official order reached 20 aircraft, and the unit price of the mass-produced "Black Ghost" was $420,000, and the total value of the contract was $10.9 billion, the highest order ever received by the Swedish Air Force! …,

While the Swedish Air Force was eagerly awaiting the delivery of the first full-fledged Black Spectre, the new fighters had already appeared in northern Norway, also in Scandinavia.

Before returning to the Netherlands from the "Nordic Country", Lynn followed Rommel and General Schchenover, the current commander of the Imperial Air Forces, to the secret air base "Leipzig", about 200 kilometers northeast of Narvik, where he witnessed the "Black Ghost" performance. In the battle drill with the M-26ZA, the new fighter produced by Saab, which has a dominant controlling stake in the Reich, won 5-3 -- that is, when the "Swallow" and the "Black Ghost" across the continent faced off, it took five to lose three of the opponent's aircraft, and this was the drill data obtained after the Empire's elite pilots took over the new fighter for a short time.

Lynn is no stranger to the "Black Ghost", he was unable to participate in the acquisition of the Swedish Saab Company because he went to the Soviet Union to direct the assassination of Stalin, but this plan to borrow chicken and eggs was first clearly proposed by him, the Empire's aviation technology and expert strength, Sweden's industrial base, military and political support, Saab Company really lived up to expectations and developed a fully enhanced version of the M-262. Not only that, but General Schchenover revealed to Lynn that the two-seater "Black Ghost" has also been developed, and the prototype is being tested at the aircraft test site in Sweden, and if it goes well, the first production model will be able to become the new iron wing of the Imperial Air Force before the autumn. This two-seat fighter is different from the heavy fighter of the propeller era, its maneuverability seems to have decreased compared with the single-seat model, but the combat effectiveness of air combat has been multiplied in theory, and the reason for such a wonderful change is that the new fire control radar produced in Switzerland and the X4D air-to-air guided missile produced in Argentina are the roots of "magic"!

Although he is not a hardcore World War II military fan, the experience of serving as a World War II section of the military website still allowed Lynn to gain a wealth of technical and tactical knowledge before the crossing. Among the many technological riches of the Third Reich, the X-Chai played a very subtle role as the progenitor of missiles.

On the one hand, its appearance means that the history of human air warfare has jumped to a new level, on the other hand, although 225 X4 prototypes have been produced by August 1944, the declining Third Reich has been unable to carry out larger-scale production, and has not even been able to officially put this extremely advanced weapon into actual combat, thus leaving infinite regret and reverie for future generations.

During his tenure at the Strategic Staff, Lynn gained a comprehensive understanding of the post-war layout of the Empire, and South America, with its large number of German immigrants, was not only a refuge for a significant number of military and political personnel, but also a fertile ground for the Third Reich to retain and develop its military strength. With the implementation of the "Aryan Ark Project", thousands of military experts and technicians arrived in Argentina, Chile and other countries either by transport submarines or through neutral countries, including the genius pioneer of flying wing aircraft, Rema. Horton, who continued to engage in military research at secret local bases or factories under the guise of civilian industry, made remarkable achievements in key areas such as wireless guidance, microwave radar, and high-speed torpedoes in the nearly two years without worrying about Allied bombing, and became a major source of enriched uranium for the Empire's nuclear weapons program from almost scratch.

Constrained by key technologies such as fly-by-wire control systems, the Go29 flying-wing aircraft project has produced a new prototype in Argentina, but it has not been able to achieve a breakthrough in practical use. There are often gains and losses in the field of technology, and wire-guided/wireless air-to-air guided missiles have demonstrated amazing air combat strength in live-fire tests after being fully improved. At the Nordic air base called "Leipzig", Lynn saw the real thing shipped from South America, the X40 missile body is slender and cigar-shaped, with 4 swept main wings and 4 smaller tails, at the top of the two opposite main wings are two storage compartments for control wires, and the top of the other two main wings is a tracer tube, which is convenient for pilots to observe its course, and the tail end has a control mechanism that can control the pitch and deflection of the missile, and the power plant is a rocket engine. Compared to the original model, the X4D is a major improvement in the use of more stable and reliable solid-state fuel, and the main structure inside the missile body has also been rearranged. The warhead of the warhead weighs 20 kilograms, has a fragmentation kill radius of 76 meters, and can be detonated by the pilot by remote control, impact detonation or acoustic proximity fuse according to the noise of the target engine. After launch, the missile rotates at a speed of about one revolution per second to reduce the effects of uneven engine thrust and asymmetry of the aerodynamic plane. The gyroscope is responsible for monitoring the attitude of the projectile so that the course can be accurately modified according to the control commands, even during rotation.

Although the X4 was originally designed for single-seat aircraft, it was difficult to maneuver missiles and aircraft at the same time, so they decided to use a multi-seat aircraft as a combat platform as early as early 1945, and until the two-seat "Black Phantom" was in place, the MB2 two-seat night fighter was currently the only effective carrier for the Imperial Air Force. A typical attack process is as follows: the carrier aircraft reaches the same or slightly higher altitude as the target, the guided missile is dropped by a special pylon, and the pilot uses a joystick to remotely control the missile in the cockpit through a radar fire control system. Seven seconds after launch, the acoustic and impact fuses are activated, and after 30 seconds if the target is not hit, the self-destruct device is activated, while the acoustic fuze is activated at a distance of about 40 meters from the target and detonates the warhead when it is delayed to about 5 meters from the target. At an altitude of 3,000 meters, the X can reach a maximum speed of 1,200 kilometers per hour, and the control form has both wire-guided and wireless -- without interference from the enemy's radio equipment, the wireless remote control device can play a role within 10 kilometers, and the wired remote control effect is similar to that of wire-guided torpedoes, and the maximum range of action in air combat is 4 kilometers, far exceeding the effective combat distance of the United States, the Soviet Union, and the British fighter guns and air-to-air rockets.
