Rebirth of the 1980s: The Military Industry Empire

Civilian air conditioners are cheap and convenient, but they cannot be installed in vehicles because they cannot withstand the bumps and jolts. In later years, you might see household air conditioners installed in some RVs, but they are not sturdy at all. Driving on the highway is okay, but never go off-road, as the constant shaking can easily cause them to break.

The air conditioners used in tanks are naturally specially made. If using a compressor, it must be a high-speed rare earth motor. A rotation speed of tens of thousands of revolutions is needed to make the compressor small enough while still possessing extremely strong performance.

If not, then a variable displacement air conditioner must be used.

“This kind of refrigeration air conditioner can be perfectly test-fitted to the M1 tank's NBC system. Moreover, the cooling power is a full three kilowatts, which can not only meet the needs of the internal crew but also provide a better working environment for the electronic equipment.”

Air conditioning is not only for people but also for equipment. The American M1 tank initially did not have air conditioning, but by the time of the M1A2, it was installed because the amount of electrical equipment inside was increasing. With the addition of the commander's panoramic sight, the internal temperature of the tank could not be too high to ensure the normal and stable operation of the tank's electronic equipment.

Later, the three-kilowatt cooling power was not enough. By the time of the M1A2 SEP v2, the cooling power had been increased to seven and a half kilowatts. With this powerful output, the interior was cool enough.

However, this is not the most. In order to export equipment to tropical regions, the East has achieved a maximum cooling power of 12 kilowatts. Of course, these are things for the future. Right now, just promoting this three-kilowatt cooling device is enough.

Dr. Wright nodded: "That's right, people can endure, but equipment cannot. If the internal temperature is too high, the equipment may malfunction. Air conditioning does need to be added. After returning, I will suggest to the relevant departments that they come and inspect your vehicle air conditioners. If possible, we are willing to purchase five hundred sets."

Five hundred sets, at two thousand dollars per set, that's one million dollars! For Dr. Wright, this amount of money is insignificant, too little. As long as it is determined to be suitable, not to mention five hundred sets, two thousand sets can be purchased.

But for Qin Yang, this is just a small appetizer; the important thing is what comes next!

“You also used a 105mm gun on this tank. Is there an export license for this gun?”

“Of course, this is not the NATO standard L7 tank gun. This is our own independently developed Type 81 tank gun. Its barrel is longer than the L7 and is different from the L7,” Qin Yang said with confidence.

Dr. Wright smiled. This matter had little to do with him, and he didn't need to worry about it.

However, Qin Yang's words made him have to become serious.

“In order to intervene in European conflicts at any time, your side has created a heavy tank. However, this type of tank is not convenient to transport. In fact, your side also needs a light tank that is easy to airlift and can handle emergencies at any time.”

The American's main force is the M1 tank, weighing sixty to seventy tons, which is too difficult to transport by plane and can only be transported by sea, which is destined to be slow.

Therefore, they also need light tanks!

“Are you talking about the Marine Corps' M8 Armored Gun System? That kind of tank simply cannot withstand the test of war. The United States Army does not like it.”

Qin Yang shook his head: "Of course not, that kind of tank is already outdated. If you only pursue lightness and give up other performance, that is absolutely not acceptable. Take our 105mm caliber tank gun, for example. Although the caliber is not very large, after we improved the ammunition, it now has a penetration depth of over 500mm."

Dr. Wright was stunned again: "So strong?"

The L7 tank gun can sell well throughout the Western world, not only because of its power but also because of its good adaptability. This tank gun is lightweight, and the breech is very short, making it easy to install on various tanks.

As for the power, it was not strong at the beginning. The first L28 armor-piercing projectile had a penetration depth of only over 200mm, and the L52 only had 250mm. This situation continued until the appearance of the M735, which used liquid phase sintering technology. The appearance of this epoch-making armor-piercing projectile increased the armor penetration ability to 300mm.

Of course, in this era, this technology was mastered by the East and then sold to the British at a high price. This was also an important fortune earned by Qin Yang in the early days.

As for the Americans, they began to take the path of depleted uranium bombs. After developing the M774, they continued their efforts and developed the M883.

The armor-piercing projectile put into service in 1983 is currently the most advanced armor-piercing projectile in the hands of the Americans. After some efforts, the armor penetration ability has finally exceeded 400mm.

As for armor penetration ability exceeding 500mm? That would have to be the M900, which mainly relies on high chamber pressure. By using a special M43 fast-burning propellant, this shell has a high chamber pressure of 517 megapascals.

Because the chamber pressure is too high, ordinary tank guns cannot use it. If they do, the barrel will explode. Only the M68A1 tank gun on the M1 tank can withstand this huge chamber pressure.

However, the effect is also good. By relying on this method, the armor penetration depth of the American tank gun has finally reached 540mm.

Now it's only 1984, and Qin Yang is saying that he has an armor-piercing projectile with a penetration depth of 500mm. This is simply too heaven-defying!

Qin Yang smiled. What's so great about this? Although our propellant technology is not as advanced as the Americans, our barrel is longer!

To increase the power of an armor-piercing projectile, you must increase the speed of the armor-piercing projectile. Increasing the energy of the propellant is one aspect, and making good use of the energy of the propellant is another. When a tank gun fires, you can see a ball of flame coming out of the muzzle. These are actually a waste of energy.

The longer the barrel, the more work the propellant does, and the greater the muzzle velocity of the shell leaving the muzzle.

Therefore, the East is moving forward on the road of constantly lengthening the L7. The original version is only 51 calibers. The Chinese slightly improved it to 52 calibers to avoid export restrictions and sell it abroad. Later, there was a 59-caliber version, and in the 1990s, the modified Type 94 was as high as 62 calibers, which is 6.3 meters in length, more than one meter longer than the original version!

“Not much, ten million.”

The one million just now was just an appetizer, and the ten million now is just getting on the right track. Lengthening the barrel and lengthening the penetrator are of course worth ten million dollars!

“Can you tell me how it's done first?”

Qin Yang shook his head.

If I tell you first, you will know, then how can I ask you for money?

Dr. Wright thought for a moment: "This still needs to wait for me to go back and discuss with the United States Army. This money should be paid by them."

“Well, please rest assured, if I say 500mm, then there will definitely be 500mm. If it cannot be achieved, I will compensate you twice the amount,” Qin Yang said, patting his chest.

The domestic Type 94 105mm gun can fire a penetration depth of 600mm, so there is definitely no problem with this 500mm.
