Ebro Valley, Navarra Province, Spain.

This year's winter in Spain has been particularly cold, and the usually warm Ebro Valley has also put on winter clothes. Snow and ice cover the Ebro River, and snow-covered trees stand in front of people's eyes. The surface of the river was cold and biting, and the blue mist was thick with it.

Today, however, the cold snap that had been raging for many days finally subsided, and a red sun slowly rose from the east through the bright clouds. Ten thousand rays of light illuminated the river and stained the morning mist red. The morning fog gradually receded in the sunlight, and the world suddenly became clear.

"Buzz ......" Suddenly there was a roar of engines in the air, and six fighters pierced through the clouds, turned around lightly, and flew towards the east.

The six fighters were painted with the Iron Cross, and it was clear that they belonged to the Second German Reich. True, they were intervention armies from Germany.

Because of China's involvement, the Spanish Civil War on this plane was more intense than the original plane from the beginning. After learning that the People's Revolutionary Union had sent volunteers to assist the republican government, fascist countries such as Germany and Italy also strengthened their assistance to the national army, and the scale of the intervention army became even larger. Now the army alone, Germany and Italy have sent two divisions of intervention troops.

All four fighters in the air are Germany's newest Heinkel HE-100 type. In fact, it was not only China that used Spain as a weapons testing ground, but also all other countries that intervened, whether it was the Soviet Union or Germany and Italy. No matter what doctrine or ideology, it is so pale and powerless in the face of national interests, and only those middle two will really believe that isms have no borders, but the cruel truth is that except for fools, everything else has borders.

Due to the storm fanned by the Anemo God Pterodactyl, the technological development of the Plane has significantly accelerated a lot. Especially in the field of aviation, at the end of the First World War, there was already a revolution of "monoplanes" that swept the world. Due to the excellent performance of several Chinese monoplanes, the world's aviation industry powers have invariably abandoned the ongoing development plan of biplanes at the first time and changed all their aircraft to monoplanes. Since 1918, monoplanes have been flying over the belligerents. This also led to the disappearance of many famous "last biplanes" from history, such as the Soviet Union's I153, Italy's C32, and Britain's Sailfish, all of which are gone.

In addition to the acceleration of the design of the aircraft, the biggest difference is the research progress of the aero engine, which is also much faster than the original time and space. Because China sells aero engines to the world to make money, and the aviation industry powers are not stupid, and they have begun to copycat after taking these advanced engines. The R&D departments of these countries have obtained a lot of design ideas from them, and they have found the right direction, and they have received strong support from the government.

After entering the 30s, the 1000 kilowatt (1341 horsepower) class of aviation has been popularized among the major powers. The three United States, Britain and Germany, which have the strongest technical strength outside of China, have reached the 1200 kilowatt (1609 horsepower) level of the main aviation engine. In recent years, the 1500 kilowatt (2011 horsepower) class of aero engines has also been developed by the United States, Britain and Germany.

Germany on this plane is not limited by the Treaty of Versailles, and the climbing of the technology tree has not been interrupted, plus there are samples from China for reference, so in terms of aero engines, especially in piston engines, the Germans did not distort the technology tree. Therefore, the flight of the second son of the plane is no worse than that of Britain and the United States.

At present, this Heinkel HE-100 fighter is the latest German fighter. It is powered by Germany's latest MW35 2,000 hp twelve-cylinder liquid-cooled engine, which is an advanced piston engine with a supercharger.

Even the entire fuselage is completely different from the work of the same name in the original time and space, but it is closer to the "Firefly" of the British in the original time and space, and the fuselage is more streamlined. The maximum speed of the HE-100 can easily go up to 660 km, the range is 1400 km, the addition of auxiliary fuel tanks can be increased to 2200 km, the ceiling is 14000 meters, and the climb rate is 19. 7 m/s. The armament consisted of two 20-mm cannons and two 13-mm machine guns in the nose and two 13-mm machine guns in the wings.

In all countries except China, this fighter is definitely excellent. So when the Germans threw this fighter into the Spanish Civil War, the Republican side was miserable.

Due to the limitations of national strength and the ongoing political instability, the air force of the republican government is now heavily equipped with old-fashioned aircraft that the big hooligans disarmed and replaced after World War I. Although it was a good thing at the time, it is now, sixteen years later, both the engine and the firepower are outdated.

As soon as the two sides fought, the planes on the Republican side were shot down like turkeys by the Germans, and there was little power to fight back. Later, the Soviet Union sent the latest "I-17" fighters, but only slightly reversed the situation. Adhering to the Russian tradition, the firepower of the "I-17" is very strong, but the engine is only 1700 horsepower, which is one level worse than the HE-100.

"Halle, the weather is really nice today, it looks like the Russians won't be coming out......" Second Lieutenant Mateus, the squad leader, looked at the rising sun and said on the squad channel.

"If the Russians don't come out, what about the French?" said Haller, a little uneasy.

"Yes, those Frenchmen are so annoying, it's none of their business, but they come and intervene...... Mateus said indignantly.

Yes, unlike the history of the original plane, the French also intervened in the Spanish Civil War. What is more funny is that although France is also a fascist regime, the standard far-right, they are helping the Spanish republican government, the ultra-left regime.

But when you think about it, it's not surprising at all. Because France is the birthplace of the world revolution, everything such as "opposing the monarch" and "hacking the king" is a politically correct thing for this country, especially for the French people, who have a strong revolutionary tradition, and this is the concept in France, both on the left and on the right. The second is the old feud between France and Germany, based on the basic principle that "what the Germans oppose, we must support", it would be strange if the French did not help the Republicans.

In the words of French Prime Minister Jean-Michel Megre, "I hate the Public Property, but I hate the Germans even more!"

This fascist is not another fascist, the fascist in France and the fascist in Germany and Italy cannot urinate at all. Although France was also dragged by Britain to participate in the embargo and blockade of both sides of the civil war at the beginning, the French did it half-heartedly, and the blockade line on the side of the Republican Army by the French was simply useless. The French not only pretended not to see the supplies imported into the Republican Army, but even brazenly dispatched large cargo ships to help the Republican government resell the armaments.

When I got to the back, I saw that even the Chinese came to help, and the French couldn't sit still. In the name of "supporting the legitimate government of Spain", they directly withdrew from the embargo organized by the British. Although the army has not yet been dispatched to help, a group of pilots and fighters have been organized to come over in the name of volunteers.

The aircraft provided by the French is also their latest fighter, the D520, which is close to the original namesake in appearance, but with a 1950-horsepower engine and more firepower. After encountering the D520, the HE-100 has little upper hand, the performance of the two aircraft is almost the same, and even the D520 has an excellent aerodynamic design.

..................................................................

Now the Russians are slightly inferior in aircraft, so they use tactics to compensate. Their most common tactic at present is to hide in the clouds and rush down to ambush the German planes while they are not looking. In good weather, the planes of the Russians usually do not come out, so as not to be beaten. But the French are different, their aircraft performance is enough to be frontal and hard-hitting Germans, so naturally they are not picky.

"I don't think we'll be so unlucky, the French have so few D520s. If I could even run into a Frenchman on my daily patrols, I'd buy a lottery ticket......" Matthaus said jokingly.

The only good news for the Germans was that the number of D520s was too small, with fewer than 50 in Spain. After all, this kind of aircraft has just been introduced, and even the French Air Force itself is not officially equipped.

"I'd like to touch the French and see if their D520 is as good as it gets......" Another pilot, Bremer, said unconvinced.

As soon as Bremer finished speaking, dozens of chains of fire fell from the sky, and one of them hit his landline.

With a loud ......bang, the rear fuselage of the Bremer landline was blown out, and the right tail was also blown away, and the entire fuselage looked as if it had been bitten by a giant beast.

"Oh no, enemy attack! Disperse ......," Squad Leader Matthaus shouted in the channel. He pulled the joystick and tilted the fuselage to dive down. Out of the corner of his eye, he could already see that Bremer's landline was dragging black smoke down.

The enemy aircraft came from above, of course, they had to run down, and as long as the enemy aircraft also chased down, they would have the opportunity to counterattack with the excellent low-altitude performance of the HE-100. However, what made Mateus feel strange was that he had just paid attention to the plane above, but he had not found the plane at all, so how could he be ambushed by the enemy plane? The only possibility was that the enemy plane launched an attack from a high altitude above the 10,000-plus high-level cirrus clouds.

"Damn, I knew I could fly higher...... "Matthaus thought hatefully. Because the planes on the Republican side like to run at low altitudes, in order to spot these opponents at low altitudes, the Germans also have to lower their altitude when patrolling, otherwise they will be easily missed.

Mateus, an experienced old bird, did not panic when attacked, and controlled the landline to connect two rolls during the dive, and dodged several shots from the enemy plane. But the enemy plane kept biting him tightly, and tracer ballistics like chains of fire kept flashing around his plane.

Damn, I've met an old bird! Mateus is sweating out. He quickly turned the lever and cut diagonally towards a mountain peak. Just as he tried to evade the pursuit of the enemy plane through the peak, he found that the enemy plane did not chase him.

At this time, he also saw the appearance of the incoming enemy plane.

"******! it's a big flying bottle, it's a Chinese plane!" heard Haller's scolding over the intercom.

That's right, the enemy planes that hit them just now were a group of fat planes that were stout, round, and cute. Such an obvious feature, at first glance, is the legendary "flying big bottle", China's J-7 "Big Red Eagle" fighter.

There were now eight bottles in the sky, and now the planes were split into two groups, half of which were climbing upwards, apparently preparing for another dive attack. The other half hovered in the air, covering friendly aircraft.

"Damn, didn't the intelligence say that the Chinese only came to the army? Those intelligence officers all eat feed!" Mateus couldn't help but scold.

"Quick, retreat......" Mateus saw that only half of the six planes on his side were now left, and there were many more milk bottles than them, so it was not a good idea to hold on.

The three remnants of the German aircraft fled in disarray, but the superior Chinese fighters did not take advantage of the situation to pursue.

"Squadron leader, why don't you chase it? There are three more. Second Lieutenant Ming Zongyue said excitedly. He shot down Bremmer's plane just now, which was also his first record since his debut, and he is now dancing with excitement.

Captain Gao Zhihang looked at the German planes in the distance and said: "The front is the position of the Germans, are you going to catch up and prepare to eat anti-aircraft artillery? Besides, it has already been said above, we should not be too careful, this is Spain." ”

Gao Zhihang took the wingmen around again, and said, "Okay, we have cleared the enemy's patrol planes. Mission accomplished, go home......"

The bottles made a half-somersault with their disproportionate agility and flew eastward.

......................................................

Headquarters of the People's Revolutionary Union Volunteer Army.

"Commander Yang, today our pilots made six sorties and shot down a total of 14 enemy planes...... "Brigadier General Gu Yuemo, commander of the Volunteer Air Force, said.

"Well, it's not bad. Have you filmed all the films?" asked Yang Ning.

Gu Yuemo said with a smile: "It's all filmed, and the pilots all complain that it is too troublesome to shoot during actual combat, which affects their ...... performance."

Yang Ning scolded with a smile: "These stinky boys, Spain is not here to brush their grades. Conducting combat tests, as well as advertising our weapons are our main tasks. If we don't shoot the film well, how can we do publicity? However, we can't ignore the problem of affecting the performance, and if they don't perform very well, it will also affect the image of our weapons.

Gu Yuemo thought for a while and said, "Then leave the shooting task to the two-seater, there is only one pilot on the single-seater, and it is really too busy." In the future, each squad will have a two-seater model......"

"Okay, I'll leave this matter to you......"
