In late March, the two Orr cruisers were bitten by the cruisers of the navy of the Kingdom of Krull, and after running for several days, they could not escape, and finally after running out of coal, they were forced to flee into the neutral kingdom of Lieji.

With a smile on his face, the Kingdom of Liej seized the two Luohai-class dome cruisers in accordance with international conventions and repatriated the crews of the two ships.

Immediately after that, another cruiser Orr was surrounded and annihilated and sank.

At this time, although there were still two broken cruisers left in the navy of the Orr Kingdom overseas, it was difficult to support the lone estimate for too long.

It turned out that the use of ordinary cruisers as broken ships, sustained combat capabilities, as well as survivability, were too low.

Especially in the absence of overseas supply bases, it is difficult to continue to carry out the operation of breaking diplomatic relations, and even if the Orr Kingdom's breaking ships are secretly supplied by the Daheng Empire, it is difficult to obtain supplies.

The breakdown of diplomatic relations between the navy of the Orr Kingdom has achieved certain results, sinking tens of thousands of tons of merchant ships of the Krull Kingdom, but the effect is still very limited.

This also attracted the attention of the navies of various countries, who realized that the operation of breaking diplomatic relations was effective, but specialized ships were needed.

Breaking ships require higher speeds, greater range, and self-sustaining capabilities.

At the same time, this is also because the naval powers are highly concerned about the anti-sabotage operations, and how to protect the sea routes, protect merchant ships, and block and encircle the enemy's sabotage ships in wartime has become an important topic for the major naval powers.

Whether it is the navy of the Krull Kingdom, the navy of the Valya Empire, or even the navy of the Daheng Empire, they have all conducted in-depth research on the topic of breaking diplomatic relations and counter-breaking diplomatic relations.

Other countries don't know, but the conclusion that the Daheng Empire has come to is that the best way to counter the destruction of diplomatic relations is to use the new Fengyang-class armored cruiser, which has high speed, comprehensive protection, and firepower, and at the same time has a very good endurance as an ocean-going warship.

Conversely, this kind of armored cruiser is also very suitable for use as a broken battle ship if the endurance is increased.

They discovered that armored cruisers had the potential to become all-rounders.

However, in order to meet the diversity of tasks, the tonnage of armored cruisers is also increasing, and at the same time the price is becoming more and more expensive!

This is also a kind of reality in the development of the Navy, that is, the cruiser is larger!

The armored cruisers of the Daheng Imperial Navy are actually still classified as first-class cruisers, and the displacement of their Fengyang-class armored cruisers has already reached more than 10,000 tons, which is larger than the first-class battleships of other countries.

The first-class cruisers of other countries are actually similar, and the tonnage of armored cruisers of many countries is also eight or nine thousand tons, and the large bunch of first-class protection cruisers of the Krull Kingdom are also seven or eight thousand tons.

The Orr War is still going on, but the navies of all countries in the world have started a new naval construction one after another!

Not to mention other countries, but also to say that on the side of the Krull Kingdom, a series of problems in the Orr War, their high-level naval teams, especially the problems exposed in the Battle of Ian and the Anti-Breach Operation, have been analyzed in detail.

In the end, they came to several conclusions, and the conclusions they came to were strikingly similar to those reached by the Daheng Imperial Navy after last summer's exercises!

First of all, the core conclusion is that the close blockade is no longer suitable for the needs of modern warfare!

The presence of shore artillery and torpedo boats, the supply difficulties of the blockade fleet, and the lack of self-sustaining power all make the close blockade more and more unrealistic, and will put the fleet in a great crisis.

The future blockade should be based on long-distance blockade, just as they are doing in the Orr War, using a large number of cruisers and other small and medium-sized warships to carry out surveillance, and when the enemy fleet goes to sea, the main fleet will be dispatched to encircle and suppress and destroy the opponent in naval warfare.

Based on this shift in core theory, they came to a number of key conclusions, the first of which was that low-freeboard warships could no longer meet the needs of war.

As for the open-air battery, although it is exposed to a greater risk when fighting against the shore fire resistance, since they are not performing the task of close blockade, then there is no need to worry about facing the condescending shore fire resistance, and at the same time, the current technology is not mature, and the turret warship will cause the center of gravity to be too high, the open battery is still the best choice.

This conclusion is the same as in the Daheng Imperial Navy, the Jingzhou-class battleships still use open-air turrets based on the same considerations: they no longer carry out close-range blockade missions, and the technology in all aspects is not mature enough, and the use of turrets will lead to too high a center of gravity.

And the conclusion of the high freeboard and open-air batteries directly gave birth to the Jingzhou-class battleships.

Now the navy of the Krull Kingdom is also following the same path, and they have made up their minds to build a high-freeboard capital ship.

In addition, the Navy of the Kingdom of Krull came to the conclusion that the existing small and medium-caliber naval guns were seriously insufficient in firepower and could not effectively counter small and agile high-speed torpedo boats.

To deal with those torpedo boats, the Navy of the Kingdom of Krull needed more specialized torpedo boat destroyers, small and medium-caliber naval guns with a higher rate of fire.

But there are no rapid-fire guns in the navy of the Krull Kingdom.

It is also impossible for them to study rapid-fire tube withdrawal guns many years in advance like the Great Heng Empire, and apply them to the Jingzhou-class battleships.

They still need to be re-developed, but they also have the technical basis of the Cole gun mount, which is a gun mount that uses hydraulic control and gravity retraction, but the gun barrel is still linked to the upper gunship, and when the artillery system is retracted, the gun barrel is connected to the upper gun mount for back and forth movement.

The navy of the Krull Kingdom has given their Royal Arsenal a research and development order to improve the gun mount to increase the rate of fire, and it is unknown when the rapid-fire cannon will be available.

At least so far, they don't have any reference, although the Daheng Empire has a rapid-fire cannon, but this thing is still a top-secret project, and it has not been officially installed, only a small amount of tests are carried out, and the outside world does not know that the Daheng Empire has a tube retreat rapid-fire cannon.

In addition to rapid-fire guns, torpedo boat destroyers are relatively simple,

They were going to design and build more specialized torpedo boat destroyers, with powerful guns and higher speeds, to drive out enemy torpedo boats and protect their own battleships.

At the same time, it is necessary for large lightning strike ships to be able to act with the main fleet and launch lightning strike operations against the enemy fleet, which requires ocean-going performance.

The warship design department of the Navy of the Kingdom of Krull combined the two requirements into one, and finally proposed the concept of a torpedo boat destroyer.

This torpedo boat destroyer concept is completely consistent with the destroyer concept in the Daheng Imperial Navy!
