Because at that time, torpedoes were still compressed by air, and the effective range was only a few hundred meters, and the speed was also low.

And the destroyers of thousands of tons are very embarrassing, although the speed is fast, but the firepower of the ship's guns is average, and the torpedoes can be directly ignored, and there is basically no chance of winning against the two or three thousand tons of protective cruisers of other countries, but it is actually a bit wasteful to say that it is used for anti-torpedo boat operations.

Generally speaking, the practice of various countries is to use large torpedo boats of several hundred tons with cruisers of several thousand tons or even two or three thousand tons.

The super-armor torpedo boat is a typical example of this.

However, the Daheng Imperial Navy did not do so, and the main reason was that the Daheng Imperial Navy wanted to obtain the ocean-going high-speed lightning strike capability, and various tests proved that the thousand-ton destroyer was the best cost performance.

It's a pity that the thermodynamic torpedo has not been made before, so there are only empty ships, but there is no torpedo such a big killer, so that the thousand-ton destroyers of the Daheng Empire are nondescript, even within the Daheng Empire, there are many people who think that the destroyers of the Daheng Empire are too cost-effective.

But now, when it is replaced with a thermodynamic torpedo, the combat effectiveness of this destroyer will be greatly improved, and if a war breaks out in the future, these destroyers of the Daheng Imperial Navy will be able to accompany the capital ships to fight and launch lightning strikes when necessary.

When a bunch of torpedoes with a speed of more than 30 knots cross thousands of meters to attack an enemy ship, this is also a very touching thing.

With the development of thermodynamic torpedoes and entering practical application, a large number of destroyers in the Daheng Empire have greater combat value, rather than just miscellaneous as before.

And this can be seen from the beginning of the construction of more new ocean-going destroyers in the Great Heng Empire.

Although the Daheng Empire also built a lot of destroyers in the past, the number was still not too much, after all, the destroyers at that time were used as cheap light protection cruisers, but the actual effect was definitely not as good as that of two or three thousand tons of cruisers.

At that time, the Daheng Empire still had a large number of two or three thousand tons of protective cruisers built in the early years.

However, with the advancement of technology, a number of old protective cruisers have been unable to adapt to the naval warfare of the new era and have been forced to transfer to the second line or even retire, but the Daheng Empire has not built a new generation of 3,000-ton protective cruisers.

At the same time, in the fourth shipbuilding plan of the Daheng Imperial Navy, the cruiser was repositioned as a heavy armored cruiser and a light armored cruiser.

Among them, the heavy cruiser was used to replace the previous large-tonnage protective cruisers and 10,000-ton armored cruisers, so the performance indicators such as 10,000-ton tonnage, 200-millimeter naval guns, and a unified fire control system were adopted.

As for the light cruiser, it is finalized at the level of four or five thousand tons, using side armor and high speed, and the original design intention of this light cruiser is to accompany the main fleet to carry out close-range lightning protection operations, or to carry out avant-garde reconnaissance missions with heavy cruisers and battle cruiser formations.

But further down, there are no cruisers of the two or three thousand ton class, only destroyers of more than a thousand tons.

This also makes the destroyers of more than 1,000 tons of the Daheng Empire need to take on the task of light protection cruisers of two or three thousand tons of other countries.

The limitation of tonnage also made the destroyer's gun firepower poor, and the range and speed of the early air torpedo were not good, so the destroyer of the Daheng Imperial Navy could only undertake anti-lightning combat missions for a long time, and other than that, it was a miscellaneous.

But now with thermodynamic torpedoes, this is different, and these destroyers can launch ocean-going lightning strikes with torpedoes.

And this point has been pursued by the navy of the Great Heng Empire for many years.

The Daheng Empire engaged in this kind of large-tonnage destroyer, and other countries also followed up after seeing it, but the follow-up was not large.

This situation did not change until this year, especially after the appearance of thermodynamic torpedoes, and all countries, especially the navies of major powers, have begun to pay attention to large-tonnage destroyers.

The same is true of the Orissa Empire, they don't have their own thermodynamic torpedo technology, but the Kyle Empire does!

The thermodynamic torpedoes of the Daheng Empire can be sold globally on super-armored torpedo boats, and the thermodynamic torpedoes of the Kyle Empire can also be bought.

The Orissa Empire has already begun to prepare to purchase thermodynamic torpedoes from the Kekel Empire, and is also preparing to spend a certain amount of money to introduce relevant technology and build it themselves, ready to equip it with a large number of torpedo boats.

After the Dyna War, the Imperial Navy of Olisa set off a large-scale combat readiness activity.

And the Great Heng Empire, which has been a sworn enemy for hundreds of years, naturally paid great attention to it and made corresponding deployments at the same time.

The navy deployed three detachments directly in the three military ports of the Kingdom of Tanner, and although the fleet was small, it also had armored cruisers and a number of torpedo boats.

At the same time, the construction of a naval base in the eastern part of the Kingdom of Tannar is being intensified to accommodate the main fleet in times of war.

If you want to berth and garrison the main fleet, the requirements for the port are still relatively high.

First of all, you have to have enough deep-water berths, the draft of the main battleship is generally a few meters larger, seven or eight meters is ordinary, even the cruiser and the like can not move more than five or six meters.

In addition to berths, there must also be supply capacity, so there must be hoisting equipment in this port, and there must be a large number of strategic material reserve warehouses.

In addition, it also has to be able to maintain emergencies, after this war, the battleship will inevitably be damaged, even if the overseas base does not have the ability to overhaul, but the emergency repair capability should always be there, so no matter what, you have to get a warship repair shop.

At the same time, in order to protect many facilities in the port, in order to protect the warships, you have to get a shore defense battery, and it can't be small, at least you have to install some large-caliber coastal defense guns on it.

And to do these well, the amount of work is not small, and the investment required is also large, and now the Great Heng Empire only has this ability at the Bowa Naval Base in the Kingdom of Lieji.

But due to the importance of the Endless Strait, this naval base in the eastern part of the Kingdom of Dynaudio is a must.

The conflict between the Olisa Empire and the Great Heng Empire continued to intensify because of the Danna War and the conflict in the Endless Strait, which was bound to cause a new round of military competition between the two sides.

But the Blue Star is not only the Orissa Empire and the Great Heng Empire, but also many other countries.

The ongoing arms race between these two countries has also affected other countries.

The first to react was not the other great powers, but the quasi-military ally of the Great Heng Empire, the Orr Kingdom on the Southern Continent.
