"Lao Xie, the management of your second machine factory is not strict enough, and there is wine and peanuts in your office! You say, if it gets out, what will happen if you Lao Xie secretly drinks at work? ”

Qin Zhenhua smiled and took the wine glass, put this small sip of wine in his stomach, and then grabbed the peanuts with his hands, threw them into his mouth, and said while eating.

"I'm not drinking during work, when I work overtime and stay up late at night, I can't stay up, so I drink a few sips, hey, you kid, don't get cheap and sell well, this is Moutai!"

That's right, there are several bottles of wine in Xie Huimin's desk, and the bottle he takes out now is Moutai! When I went abroad, after I came back, when I got off the plane, everyone would be given a bottle of Moutai, Qin Zhenhua's bottle, and I drank it all when I came back, and Xie Huimin's bottle has been treasured until now, and then I took it out to share with Qin Zhenhua, which is enough to reflect the importance of Qin Zhenhua.

On the grassland, everyone loves to drink, after all, the weather is cold, this drinking is the best way to regulate, warm the body.

Now, with a glass of wine in his stomach and warm inside, Xie Huimin said: "Okay, you can go on, how is the overall idea?" Our second machine factory, after all, is a cannon manufacturer, and the whole vehicle is not very familiar. ”

The second machine factory is mainly responsible for making artillery, if you want to say that you want to make artillery, they dare to say second, no one dares to say first, but it is different to build a whole vehicle, if you want to build a whole vehicle, it is of course the best at a machine factory.

Integrate it into the chassis of the 59 tank? How do you integrate it? This, of course, is the technical staff of a machine factory to speak, in this regard, a machine factory is the most experienced.

"Lao Xie, you are really a noble person, have you forgotten the 152-mm self-propelled howitzer project? What about that chassis? Qin Zhenhua said: "It's the 321 chassis!" ”

On the self-propelled chassis, the country has also experienced a lot of twists and turns, as the weapon began to develop in the direction of self-propelled artillery, all kinds of domestic traction artillery, also began to move closer to the direction of self-propelled artillery.

Self-research is time-consuming, a common practice is to use the existing one, knock and knock to transform it, so, many times it is called a universal chassis, in fact, this is a compromise that some medium-sized countries can not independently develop, need to engage in self-propelled artillery, just look at the existing equipment, what can meet the needs, then use what to develop.

At that time, looking at the past, the one that could be used in China was the Type 63 armored transport vehicle, so on the basis of this armored transport vehicle, a 122-mm howitzer called the Type 70 was developed.

However, the Type 63 armored car is, after all, a small armored car with only four pairs of load-bearing wheels, and when it is carried on its back, such a 122 mm caliber howitzer immediately becomes a big head, so, although it is modified, it is actually not qualified.

In particular, after the completion of the 122-mm howitzer project, the domestic development of a 152-mm howitzer began, which could not be assembled on the chassis of the 63 armored car in any case, which required the development of a special chassis.

That's right, this medium artillery universal chassis, codenamed 321, was originally developed for the 152 mm self-propelled howitzer as a supporting project, this project began in 1970, and the first prototype came out in 1978, and now, four or five years have passed, how can you not be familiar with this chassis here at the second engine factory?

In fact, there are many reasons for this, and now, hearing Qin Zhenhua say this, Xie Huimin can't help but start pouring bitter water.

In general, the research and development of normal self-propelled artillery should be based on artillery plants, but in China it is different, and the domestic manufacturers of integrated terminals of self-propelled artillery systems are not artillery factories, but chassis production enterprises!

Therefore, this 152-mm self-propelled howitzer was not built in the Second Machine Factory, but was developed in a related Bingcheng factory.

"The Bingcheng factory used to develop the Type 62 light tank, a few years ago, after the self-propelled howitzer project was launched, the Bingcheng factory applied to the state for this project, and now more than ten years have passed, the chassis they produce, the problems continue, although recently I have been hearing that it is going to be finalized, but, on the chassis, it really can't let us rest assured." Xie Huimin said: "This project, or a national key project, has abundant financial guarantees, and we want to use this 321 medium-sized chassis, then we have to self-fundraising, after all, the country's military spending is tight, it is impossible to give us a fund for this failed project, let us go to the Bingcheng factory to cooperate, we are afraid that there will be a lot of inconvenience." Xie Huimin began to spit.

In the past, all projects were allocated by the state, and the Second Machine Factory was responsible for making artillery, and this 152-mm self-propelled howitzer project actually had nothing to do with the Second Machine Factory.

The chassis is unreliable, they have heard about it, the project has been tested all the time, but it has not been able to be successfully tested, and now, their 120-mm tank gun, mounted on that kind of chassis, will it work?

Xie Huimin knew the technical strength of the Bingcheng Factory clearly, so now, when he heard Qin Zhenhua say this, he immediately began to hesitate.

"Unreliable?" Qin Zhenhua was very strange: "Isn't that chassis all used in existing finished products?" What's not reliable? ”

This medium-sized chassis, codenamed 321, is practical for all kinds of existing technologies, for example, its engine, in fact, uses a 520 hp tank engine!

However, in order to meet the requirements for the use of self-propelled guns, the engine was not deployed behind the hull, like an ordinary tank, but in the front, on the right side of the hull, the engine was arranged, and the cab was arranged on the left side, which was the same as the Israeli Merkava tank.

In this way, all the problems were solved right in front, and the huge space in the back was prepared for self-propelled guns.

Among the components, that is, the existing components of domestic tank armored vehicles, engines, gearboxes, transmission gears, etc., do not differ, except that the driving wheels are in front, and under the hull, six pairs of medium-diameter load-bearing wheels are used, which are spaced at sufficient distances at the same time, and there are three carrier wheels on it, and in this way, an elongated body is formed.

This chassis, Qin Zhenhua has understood, it is said that there is no problem with the overall design, what other technical problems can there be?

"If you want to talk about China, the R&D strength of your machine factory is of course the strongest." Xie Huimin said: "If it was in your hands, then this kind of chassis would have matured a long time ago, but on the Bingcheng Factory, the technical strength is too weak, and many small problems will be studied for a long time. ”
