Naval! Thinking of this, a smile suddenly appeared on Qin Zhenhua's face, because he thought of the German Navy's hand-pulled machine.

In the Second World War, Germany had many famous weapons, and at the same time, there were some criticized weapons, among which the hand-pulled machine was one.

The hand-pulled machine is commonly known, this is an important anti-aircraft gun of the German Navy, this anti-aircraft gun is single-shot, after each fire, there is a loader waiting next to it, loading the next shell.

Shooting artillery in the sky, it is definitely not a simple shooting at the target, the target is to maneuver at high speed in the sky, even if it is to fly a straight line, it also needs a sufficient amount of advance, in the era of no computer, completely rely on the commander's command to bind and shoot Zhuyuan, whether it can hit the target, mainly depends on luck, even if it is a large-caliber anti-aircraft gun, all pay attention to the ability to fire in bursts, however, the 37 mm anti-aircraft gun, the Germans are stubbornly using manual loading, so it is also called a hand machine, as for its effect, It is also conceivable that the 37-mm anti-aircraft guns of the German Navy have almost no achievements.

The times are constantly developing, and abroad, it has begun to enter the era of missiles, but the domestic navy still does not have this opportunity.

Missiles are in need of advanced electronic industry, and their own electronic technology is not enough to support advanced air defense missile systems, the only mature in China is the Hongqi-2 missile, which is a copy of the SAM-2 missile to create a regional air defense missile, mainly used to hit high-altitude and high-speed aircraft, but also with a liquid fuel engine, in advance before the use of highly toxic fuel.

At sea, in the midst of turbulence all the time, it is obvious that this missile will not be considered a qualified solution anyway, and it cannot be carried up.

As a result, the navy can only continue to use anti-aircraft guns, and this kind of twin-mounted 37-mm anti-aircraft gun is a product of the navy's tireless research.

Now anti-aircraft artillery, the rate of fire is a very important concept, since your mobility has improved, then I will increase the density of the projectile, in the same time, pour more projectiles past, so that you can form a barrage, as long as you hit it, then you have to be knocked to pieces!

So, in later generations, there was a 730, or even 1130, with 7 or 11 tubes of 30 mm rapid-fire *** What is it? Not fast yet! In the shortest possible time, a large number of shells were poured over, forming a barrage!

Now, there is no domestic research and development capability of the rotary cannon, can only improve the existing 37 mm naval gun, in order to study this naval gun, the relevant units have also made a lot of efforts, they have developed 6 kinds of overall schemes, 5 kinds of bomb schemes, 4 kinds of sight schemes, 3 kinds of bullet chain schemes, a total of a variety of principle sample guns, dozens of automata, dozens of body tubes, and finally, this new type of naval gun was selected in 1976, known as the 76 type double 37 mm gun.

At this time, it is logical for the army to take a fancy to it, after all, the army at this time also wants nothing, and can only rely on the air force to protect it, which is quite unreliable, so the army has long been aware of the problem of field air-raid shelters and wants this kind of artillery to come.

Qin Zhenhua has probably guessed that this double 37mm anti-aircraft gun for the army with a longer barrel should have been transplanted from the navy, and the chassis is still from our first machine factory.

"Laugh, what are you laughing at? What's so funny? At this moment, the young man saw Qin Zhenhua's smile and couldn't help but speak again.

"Xiao Ren, don't worry about it, have you adjusted it? Tune it up, let's try again. Kang Jian said.

Xiao Ren? This name, the surname is really good, and the villain is a homonym, well, since you admit that you are a villain, then I won't bother with you, let's see what you are messing up with first.

"Dong Gui, Dong Gui, this is Dong Dong Gui, please take off your drone mop." Here, testing is clearly about to start again.

When he heard the roar over there, Qin Zhenhua was also a little curious, it was a turbine engine, could it be that the big guy was coming?

Soon, an orange plane appeared in the distance, and when it flew slowly, it actually looked quite large, and at the same time, the sound was very loud.

"Attention, the target plane has come over and entered the tracking state!" Kang Jian shouted.

Here, it was obviously already in full swing, after Kang Qing finished shouting, the young man named Xiao Ren had already entered the turret, only one head was exposed, and glanced at Qin Zhenhua, his eyes were full of disdain, and then he got in.

"This is the Changkong No. 1 low-altitude target aircraft." Qin Zhenhua said: "It is said that the turbojet-6 is used, but unfortunately, the engine is a little bigger, the maneuverability is not good, and we don't have a small target aircraft, so we can only make do with it." However, it is still not exhaustive to imitate a helicopter. ”

If it is a target plane operated by someone, it is too dangerous, and a wrong shot may blow up the target plane, and the target dragged behind the target plane will be unscathed.

In this regard, there are also research results in China, that is, this kind of unmanned target aircraft called Changkong No. 1, its wings are straight, easy to fly at high altitude, the short and thick engine compartment is installed below, with a turbojet six engine, the thrust is very large, for this reason the thrust is deliberately adjusted smaller, adjusted to the original 40 percent, but it is still large, simulating a helicopter, it is not qualified at all.

Still, it's better than nothing!

Sure enough, I came to see the excitement! Hearing the words of the latter discussion, Kang Jie's heart swelled with more dissatisfaction, but at this time, he couldn't care about the cool words of these two people of unknown origin, and continued to look at the target plane flying in front of him.

The orange target plane, with a bright yellow target dragged behind it, looked particularly conspicuous in the sky, and the expression on Kang Jie's face became nervous, and at the same time, the twin 37mm anti-aircraft guns next to him finally fired!

"Tom tom!" The sound of artillery continued to sound, and one after another tracer high-explosive shells flew out, and in this afternoon, the light was not particularly good, so the trajectory seemed very clear.

Everyone was expecting it to work, but when the shell flew by, another voice came from behind: "Miss!" ”

Crow's beak! Originally, in the sound of anti-aircraft artillery fire, this sound was nothing, but now it sounds, it is extremely harsh, isn't this looking for a fight?

Moreover, what this crow's mouth said was really effective, and next, I saw the Changkong No. 1 drone dragging the target and flying in front of me intact!

"Damn it!" Someone cursed.
