Armor-piercing bullets, the core material, is naturally the bullet core, if you want to equip a large number of people, while taking into account the cost, the high-carbon steel steel core armor-piercing bullet is the most suitable material, Soviet tanks, most of them are armor-piercing bullets of this material, but the power is not high.

The harder the material, the better, so the most suitable material is actually tungsten, tungsten alloy armor-piercing bullets, even if it is a high-end armor-piercing bullet material in this era, of course, the price is also rising.

The hardness and strength of the material make the British extremely surprised, in fact, this is also an advantage that they can play, because the world's main tungsten ore is the big country in the East, which is completely close to the water, and the smelting of tungsten alloy, their own technology is also quite superb.

In order not to be swayed by the lack of tungsten ore, but also to be more powerful, the West has set its sights on depleted uranium, a material extracted from nuclear waste, which has been processed into an excellent armor-piercing material. In the same case, the power of armor-piercing bullets is higher than that of tungsten alloy.

China has long noticed the development of this aspect, and in the sixties, it began to carry out research on depleted uranium alloys, and now, naturally, there are armor-piercing bullets of similar materials, and the performance can be greatly improved.

However, this will attract the jealousy of the British, and in the end, it will be self-defeating if it is not done well, so the more rebellious shells have not been taken out just now.

Today, the pressure on the British is already great enough, and they will definitely try all kinds of ways to convince their side to introduce this tank gun, and tomorrow's meeting must be a good show.

"The adaptability of this tank gun is really good, after we introduce a full set of technology, we can easily reequip our existing 59 tanks, and the combat effectiveness of the main tank force can be improved by a grade at once." Looking at the modified tank here, Qin Zhenhua was drooling with envy.

The design concept of others is advanced, just to say that the cannon barrel is stuffed from the outside, it is much more convenient than the installation method of your own. Your own 100 slip is a specially improved turret, which can only be equipped with 69 tanks, if you want to say that it is installed on 59 tanks, it will have to be overhauled, and now, the L7 tank gun, it is very easy.

"Yes, these days, watching them modify this tank for us, we are all watching from the sidelines." Zhu Lao also sighed on the side, the West attaches great importance to ergonomics, which is completely different from the five major and three coarse systems of the Soviet Union.

Commander Huang also nodded on the side and said, "At tomorrow's meeting, if you continue to contradict the tune, it won't be self-defeating, right?" ”

Qin Zhenhua smiled: "We have already negotiated from Austria, if they don't sell it to us, we will copy it ourselves, and even save the money for licensing." However, looking at the appearance of the British, they will definitely give it to us, don't worry, Commander Huang. ”

Qin Zhenhua patted his chest, looking determined to win.

Commander Huang nodded, he was really relieved to Qin Zhenhua, thinking of last year's trip, he still remembered it at this time, and he turned them around.

Of course, if you don't have anything in your hands, then the negotiation is almost dominated by others, and at that time, the country has to spend more foreign exchange.

It wasn't until the sun went down that Qin Zhenhua reluctantly left the tank with a modified tank gun and returned to the guest house in the capital, and the next day, the official meeting began.

"Wow, this Marshal Cameron is here? It seems that they are taking this meeting very seriously. Qin Zhenhua said in a low voice, with his identity, he is only worthy of sitting in the last position, after all, the introduction of this kind of equipment is the decision of the superior leader, at this time, looking at the British who came in on the opposite side, and saw the person who was wearing a suit, but still looked very military, Qin Zhenhua also sighed.

At this time, the other party was also looking at this side, and when he saw Qin Zhenhua, the expression in his eyes was complicated, if you make an image analogy, it is like when you are eating Western food, you find a fly lying on the steak, I guess this is how it feels.

Qin Zhenhua is also gearing up, come on, I didn't plan to win today's meeting.

Qin Zhenhua's identity is against the introduction of the party, but also the domestic tank gun research and development personnel, so it is destined to stand on the opposite side, if he wins, it means that the introduction of L7 tank guns is in vain.

At this time, both sides had already sat down, and Marshal Cameron on the opposite side spoke first: "Ladies and gentlemen, we are now facing a common enemy, and we very much want to increase your armor strength as soon as possible. ”

When he said this, he glanced at Qin Zhenhua again, and seemed to be worried, for fear that Qin Zhenhua would be stunned, and then he came out to refute it again, after all, the English he spoke could be heard clearly by the other party, what if the other party pretended to be stunned again?

But fortunately, that Qin Zhenhua was just sitting upright at this time, with his hands on his knees, with a serious look, which made Marshal Cameron more satisfied, sure enough, in the countermeasures discussed yesterday, it was decided that Marshal Cameron would lobby in person, and then he could use his identity to suppress the other party, such a small technician, in such a conference room, has no right to speak at all, right?

Thanks to their strict hierarchy.

"Yesterday, we had a comparison." Marshal Cameron continued: "After testing the gun, we can find that in all indicators, our L7 tank guns are quite outstanding. ”

Hearing this, Qin Zhenhua's mouth finally burst out laughing.

In front, a leader who was listening carefully to the explanation on the other side was immediately dissatisfied, and glared back, this statement made Marshal Cameron satisfied for a while, and sure enough, this stunned young man did not dare to be stunned here.

"For example, in long-range precision shooting, we did a good job, moreover, the penetration was good, and we were fully capable of dealing with various tanks in service with the Soviet Union. And your tank gun, in terms of accuracy, is much worse than ours, and in terms of power, it is about the same. ”

"Hmph, bragging* doesn't pay taxes." When he heard this, Qin Zhenhua was behind him, and he made another sound, the sound was actually not loud, but now it was a serious venue, so this voice was quite abrupt.
