In 1935, the Soviet Navy purchased the M1932 25mm machine gun from the Swedish company Bofors, which began the development of anti-aircraft guns in the Soviet Union.

Prior to this, the Soviet anti-aircraft artillery was also fed by magazines, which could only be called anti-aircraft guns, not machine guns, and its weak burst fire was powerless against fast aircraft.

After getting it, the Soviet Navy tested and proved that this kind of machine gun had excellent performance, but, from the point of view of the Soviet Union, which liked to brush the caliber, the caliber of the 25 mm anti-aircraft gun was a little small and did not meet the needs of the Soviet Union for anti-aircraft artillery, so according to the structure of this anti-aircraft gun, they developed a 45-mm anti-aircraft gun, called "72-K".

After the caliber is larger, the power is indeed higher, but at the same time, it also means that the weight of the anti-aircraft gun increases, the number of ammunition carried decreases and other drawbacks, so it is modified, the caliber of the new machine gun was reduced to 37 mm, codenamed "61-K" anti-aircraft gun, in October 1938, the first prototype gun of "61-K" was manufactured.

In 1939, this anti-aircraft gun began to be finalized and mass-produced, and was named the M1939 37-mm anti-aircraft gun.

From 39 years onwards, this anti-aircraft gun was continuously produced from the Kalinin plant and equipped with Soviet troops, at this time, also due to the stimulation of the Luftwaffe, the classic examples of the Luftwaffe were a heavy burden on the shoulders of the Soviet army.

This kind of anti-aircraft artillery, the effect of a single gun is not very good, after groping, four anti-aircraft guns are put together to form an anti-aircraft artillery company, that is the most exaggerated. Such a kind of firepower can defend the surrounding area of 7,000 meters, which is enough to protect the shore defense artillery position.

At this time, this anti-aircraft artillery battery was nervously staring at the sky in the distance, where the German Stuka bombers had already flown over.

An anti-aircraft artillery must have eight artillery pieces, and the slightest deviation will be missed, and now, everyone is highly concentrated.

Suddenly, one of the sharpest sighted shooters noticed the situation: "This Stuka is not carrying a bomb!" ”

The Stuka bomber was lightweight, there was no built-in bomb bay, the bomb could only be hung outside, and the current Stuka, with nothing under the belly, was empty.

Oops, hit the mark!

The commander of the artillery company turned his head, and suddenly a roaring Stuka emerged from the clouds behind him.

"Quick, quick, quick, turn around!"

Almost without an order from the company commander, the first gunner began to scramble to turn the steering wheel.

The entire anti-aircraft gun weighs two tons, and now it needs to be turned by a hand-cranked turntable, which of course will not be particularly fast.

There are two anti-aircraft artillery positions in the entire place, each with four anti-aircraft guns, and the fire density is definitely not low, which is enough for them to guard the shore defense guns here.

But just now, they made a serious mistake, the anti-aircraft guns in these two positions were attracted by the flying Stuka, and now, it will take time for them to twist the cannon body by 180 degrees.

Although the Soviets were well arranged, it was a pity that they still lacked actual combat experience.

At this time, Franz, who was responsible for attracting attention, pulled the operating stick, kicked the rudder, and flew in the other direction when he approached the opponent's fire area.

While the Soviet anti-aircraft artillery was nervously turning the barrels, the terrible Stuka bombers had already dived down.

If it is attacking the enemy's warship, the Stuka bomber must be as close as possible, even a few hundred meters away from the target before pulling up, only in this case, the accuracy of the attack will be high enough.

However, it is different to hit shore defense artillery.

Because the shore defense artillery is immovable.

The Stuka bomber swooped down over the clouds at a height of 1,500 meters, and by the time it reached an altitude of 1,000 meters, the pilot had already pressed the launch button with great confidence.

Under the belly of the plane, the one-ton bomb flew off the pylon, dragging a tongue of fire towards the huge shore defense gun, and at this time, Stuka increased the throttle and pulled up and drilled back into the clouds.

This is war, the most brutal war, only after a few battles will these people mature in battle, don't look at those planes that fly in a big way, those clouds hanging over their heads, it is the most terrible.

The gunners were still turning hard, and finally turned the gun, and by this time the gunners were exhausted and out of breath, and in the sky, the Stuka bomber that had dropped the bomb was drilling hard above the clouds, and they had no time to bind and shoot the yuan, but only stepped on the firing in a daze.

"Tom, tom." The shells were still far from Stuka and could not be hit at all.

The terrible bomb, dragging a stream of blazing flames, swooped down from the sky at a rapid pace, it descended almost vertically, and with the help of the tail rocket, barely deviated in any direction, and slammed into the top of the shore defense gun.

The warhead penetrated the thick concrete shell of the turret of the shore defense gun, burrowing all the way inside, and when the shock of the impact reached the ground, everyone turned pale.

"Boom!" An even louder explosion came like this, and a blazing flame surged up under the base of the entire shore defense artillery, and the air flow carried countless fragments and flew towards this side.

"Ahh One of the gunners screamed, and a piece of concrete hit him in the chest, and he watched in amazement as the piece seemed to shoot into his body like a bullet, and he didn't feel any pain, only saw blood gurgling out of it.

The entire anti-aircraft artillery position was affected, and the coastal defense artillery, which was the protagonist of the attack, was naturally not much better.

The 305 mm barrel, which was built by Krupp for Tsarist Russia before the First World War, has been through ups and downs for decades, and now, with a loud explosion, it has separated from the base of the turret.

The bent barrel fell more than a dozen meters away from the turret and was completely scrapped.

The barrel in the middle barely supported and did not fall, but a blazing flame came out of the barrel, which looked so weird.

With one Stuka in front of it attracting attention, the other sneaking out of the clouds, a successful sneak attack by German naval aviation took out one of the most important Soviet coastal defense guns, and at the same time made the Soviets realize the gap between them and the Germans.

The other coastal defense artillery positions, in a brief shock, immediately changed their tactics, their anti-aircraft guns, aimed at the clouds in the sky, and even fired mercilessly at the clouds.

Everywhere there was smoke of gunfire.
