During the Daheng Unification War, that is, when the breech-loading rifled guns first appeared, in fact, the caliber of the breech-loading artillery developed by various countries at the beginning was not consistent, and there were all kinds of messy calibers.

For example, in the field artillery of the division, the Great Heng people used 75 mm, the Orissa Empire used 90 mm, the Krull Kingdom used 78 mm, and the Kehl Empire used 80 mm.

The difference in caliber actually means a difference in tactical concepts.

However, within a few years, the divisional field artillery of the armies of various countries has become the same level of 75 mm, of course, it is impossible to say that it is all standard 75 mm, and it is possible to say that it is more or less one or two mm.

For example, the divisional artillery of the Orissa Empire is 74 mm.

The divisional artillery of the Krull kingdom was seventy-six millimeters.

The caliber of 100 mm, 120 mm, 150 mm and many other artillery guns is like this, and it is determined by the Daheng people on this caliber, but other countries basically follow suit.

Because what follows the trend is not actually the caliber of artillery, but the tactical concept, which is a set of strategic concepts.

When the world's armies are crossing the river with the Daheng Army, there will be Daheng people who engage in 75-millimeter field artillery, and they will engage in field artillery of the same level.

The people of Daheng are engaged in 120mm howitzers, and they will also engage in howitzers of the same level.

The Daheng people are engaged in 150-millimeter cannons, and they will also engage in cannons of the same caliber.

It doesn't matter if it's useful or not, it's not suitable for you, as long as the Daheng people are equipped, it's always right to follow the trend and equip yourself.

This shows the stage influence of the Great Heng Imperial Army on the armies of the Blue Star countries!

And this influence has brought huge arms exports!

And the increasing arms exports of the Great Heng Empire also seriously affect the arms exports of the Krull Kingdom.

Weapons, especially advanced weapons, are serious high-end industrial products, and in this field, the Krull Kingdom has always firmly occupied the top spot by relying on its strong national strength and technological capabilities.

However, this situation has been greatly impacted by the Great Heng Empire in the last ten years, especially in the last five or six years.

This also further deepened the contradiction between the Krull Kingdom and the Great Heng Empire.

But it's still a minor issue.

The real big problem is that the Daheng Empire has a population of more than 200 million, a vast territory, rich resources, and is itself an industrial country, and has continued to upgrade its industry in the past ten years, and its industrial output value has exceeded that of the Krull Kingdom, and the Daheng Empire is still developing rapidly.

This frightened the world's boss, the Krull Kingdom, and saw the Great Heng Empire as the biggest challenger.

This is also the reason why the Krull Kingdom has adjusted its strategic direction since a few years ago, and the Great Heng Empire has begun a-for-tat naval arms race.

Even for this reason, he did not hesitate to win over the Orissa Empire and tried to form a military alliance to strangle the Great Heng Empire, but unfortunately it was not possible in the end, or in the end, whether it was the Krull Kingdom or the Olisa Empire, they all gave up this plan under the strong pressure of the Great Heng Empire, so as to avoid completely angering the Great Heng people.

If they really form an alliance, with the character of the Great Heng people, they will 100% be immortal.

At that time, there was only a little rumor, and those Heng barbarians began to gather the main forces of the navy, and even began to prepare for war, if the situation at that time continued, maybe the alliance between the Krull Kingdom and the Orissa Empire had not been completed, and the Great Heng Empire had already declared war on the Orissa Empire.

Although the Krull Kingdom wants to see this situation, the Orissa Empire is not happy!

Why do we have to be beaten for the sake of an alliance?

At that time, even if the Krull Kingdom helps the Orissa Empire as an ally, at most it will be a copy of the Hengao War decades ago, and the Orissa Empire will not die at that time?

In the Heng Austrian War decades ago, whether it was the Great Heng Empire or the Orissa Empire, in fact, they were all losers, and the winners were other countries.

Therefore, the Orissa Empire is not willing to let itself be beaten as a leading bird, and when the time comes, no matter whether they win or lose, their Orissa Empire will suffer.

So the alliance is not a matter of conclusion.

However, the military alliance between the Krull Kingdom and the Olisa Empire did not take place, but this did not prevent them from deepening their cooperation in the military field.

Many of the advanced weapons research of the Orissa Empire have been greatly helped by the Krull Kingdom.

This is the case with rapid-fire guns in previous years, and the reason why the Orissa Empire was able to come up with medium-caliber rapid-fire guns so quickly was because of the relevant technical information obtained from the Krull Kingdom, otherwise with their background, it is estimated that they would have to toss for several years.

The Krull Kingdom is bent on pulling the Orissa Empire against Daheng, and does not hesitate to support the Orissa Empire for this reason, which also fully demonstrates the Krull Kingdom's defensive psychology against the Daheng Empire.

And this defensive psychology is getting bigger and bigger every year.

However, it is their business for others to guard against Daheng, but Daheng people themselves are still immersed in developing themselves.

In the sixteenth year of the reign of Qiansheng, the Daheng Empire increased its investment in the Kingdom of Tanna, mainly to build a railway network in the area of the Kingdom of Tannar, so that the troops and materials of the Daheng Empire could be quickly transported to the Kingdom of Danna.

Internally, the Daheng Empire still holds high the banner of agricultural and industrial development, steadily promoting the development of modern agriculture and modern industry.

In other countries, the most talked about is industry or something, but in the Daheng Empire, agriculture and industry have always been equally important, but the agricultural development of the Daheng Empire and the agricultural development of other countries are not the same, and the Daheng Empire is developing towards the path of modern mechanized agriculture.

And this goes hand in hand with industrial development.

Sixteen years have passed, and the sales of various types of agricultural machinery in the Daheng Empire have been further improved, especially the production and sales of various agricultural machinery powered by gasoline engines, such as gasoline engines and tractors.

Compared with the 16th year of Qiansheng, the production and sales of gasoline engine machinery in the Daheng Empire increased by 60 percent.

However, in the ordinary passenger and cargo fields, the current gasoline engine is still a little worse.

Although there are cars now, the current cars are still too primitive, expensive, and immature, so this thing is still a high-tech test product for the time being, and it is not even qualified to be used as a toy for the rich.

However, in the field of special transportation, gasoline engines have begun to appear, but they are generally transported in the form of gasoline tractors.

For example, lumberyards like to use tractors with flatbed trucks to transport logs, and they used to use steam tractors, but now they use gasoline tractors.

In addition, the military also began to use gasoline tractors to tow large-caliber heavy artillery.

This is also the first time in the world that the internal combustion engine has been applied to the military field.
