Sb, in later generations, belongs to the well-known national curse, but now this bomber has nothing to do with this national curse.

Sb is the acronym of Soviet fast bomber, that is, it is a bomber! At the same time, it also comes from the Soviet large aircraft design bureau, Tupolev Design Bureau.

In the early 1930s, the Soviet air force put forward the demand for the development of a light fast bomber. The experienced Tupolev Design Bureau quickly came up with a plan and passed it. Mass production began in 1934.

In terms of appearance, this bomber is very similar to the bombers in World War II. It has a single wing, two engines at the wing root, glass navigation and bomber at the nose, and the crew cabin of two pilots above.

This is a medium-sized fast bomber with a theoretical bomb carrying capacity of 600 kg. In practice, it often carries 900 kg and a maximum range of 980 km.

At the same time, in terms of protection, this bomber has a certain armor defense ability at the beginning of design, and the body and internal key parts are made of high-strength manganese silicon steel and all metal skin.

In this era, SB-2 bomber is also a kind of bomber with excellent performance. It flies faster than many biplane aircraft!

At the same time, its firepower is also strong! There are four Soviet made 7.62mm machine guns for self-defense weapons, which can effectively form a self-defense fire network.

In the actual combat of later generations, in the eastern Chinese sky, SB-2 often shot down Japanese fighters with low defense, and once shot down five Japanese fighters.

The Spanish Civil War was a cruel war in which the Soviet Union, as the international column behind the scenes, fought an arduous battle in Spain.

Madrid is the focus of the competition between the two sides!

The SB-2 bombers assisted by the Soviet Union were deployed to the suburban airport of Madrid. At the same time, the fly 1 flight team of the air force of the Spanish Republic was deployed here.

(I really don't understand why the Spaniards have such a name, but it's a real name in history.)

It has been deployed here for more than a week. At noon on that day, Colonel Kozlov, the captain of the bomber brigade, received a news that made him angry.

At a front-line airport in badahos, our side was attacked by the vulture legion, and all fighters in the whole airport were destroyed!

This is simply unacceptable. How many rubles have been wasted in this batch of materials, and how long has it been transported halfway? Now, they have been blown to dust!

The air force of the international column also lost hundreds of people.

Now, one of their tasks is to bomb the base of the vulture Legion and return blood for blood!

After receiving this order, Colonel Kozlov, without any hesitation, immediately ordered his fleet to load bombs, fill up fuel and bomb!

Over the past few days, they have been familiar with the airspace of Spain. The location of the target they wanted to bomb has been marked on the flight chart. After a simple allocation, Colonel Kozlov first stepped on his own plane.

It seems that air operations in this era do not pay so much attention. Isn't it that simple to fly over, throw bombs, and then come back?

The engines on both sides started rumbling. The propeller of the SB-2 bomber turned, dragged the aircraft, aligned with the center line of the runway, taxied to the end of the runway, and then pulled it up.

Following Kozlov, one bomber after another also took off. A total of 16 bombers formed a cluster in the air.

Behind them, the fly 1 flight team also took off 16 fighters, all of which were two winged iraq-15 fighters.

Thirty two planes, forming a large fleet, flew over the predetermined target to avenge their comrades in arms!

For SB-2 bombers, it's just enough for them to make a round-trip voyage, while for iraq-15 fighters, they almost fly in one direction. When they complete the escort mission, they will fly to kalsada's base and land.

In the afternoon, the sky was a little yellow, and the whole formation had a dull atmosphere.

After more than an hour's flight, he gradually approached the sky above the target. Kozlov in front of him first lowered the altitude.

Why lower the height? Of course, in order not to scare the snake, after all, the lower the height, the closer the distance to be found!

According to the front view, at this time, the Germans are celebrating their victory, so their base must be unprepared. Raids can easily succeed!

The following iraq-15 fighters also reduced their altitude, and the large fleet continued to fly towards the target at an altitude of hundreds of meters.

Drop the bomb on the head of the vulture Legion and let them know their strength!

Up to now, there are still no Condor fighters taking off. It seems that they must be in a carnival!

In front of the bomber, the pilot has pasted his eyes on the simple bombing sight. The common way of this bomber is horizontal bombing. Therefore, we must be ready in time and enter the bombing state at any time.

The bomber is still flying smoothly. The bomber behind, following the pilot in front, enters the bombing route together. It is getting closer and closer to the target!

Closer, closer!

"Damn it, who informed the target coordinates?" The pilot took his eyes off the bombing sight and shouted, "there's nothing down there!"

The cockpit above can't be seen directly below, but the navigator has a wide field of vision. There are villages, farms and manors below. Where is there any air force base!

If it is not the flight error all the way, it can only be wrong information!

The pilot was quite depressed. There was no fart below. What else did he bomb!

It is not easy to observe the ground from the air. There will be various obstructions. Moreover, the speed of the aircraft is quite fast, which increases the difficulty.

Now, the pilot has reported that he has found nothing, and Kozlov is also cluttering in his heart. Is he going to return in vain?

"Pull up the bomber and we'll fly higher." Said Kozlov.

The more you fly, the farther you see. Maybe the target is nearby?

With his order, the pilot on one side pulled the steering wheel, and the 12 meter long bomber raised its head. The belly looked very clear on the ground.

"Hit me hard!" On the ground, a young general squatting in an air raid shelter with a camouflage net on his head and observing the sky with a telescope shouted.

The 40 mm boforth antiaircraft guns removed the camouflage net, and the barrel shook up.
