The Olisa people also know this, the international disputes of these years are so simple and crude, what cannot be obtained in war, do not expect to be obtained in diplomatic situations.

So the Olisa people just shouted a few words, but there was no other reaction, and now the Olisa people are more focused on the defense of their homeland.

They urgently passed the 'Native Defense Project', which mainly covered two major areas.

The first is the construction of ground fortifications, including the construction of coastal fortifications and anti-landing fortifications in coastal cities, they are ready to build dense anti-landing fortifications on the northern coast, that is, along the coast of the Endless Strait and the coast near the Endless Strait, and at the same time build shore fortifications at the entrance of inland rivers in the port cities along the coast of the homeland, especially in important military and commercial ports, to prevent the fleet of the Great Heng people from shelling the above areas, and also to prevent the fleet of the Great Heng people from going up the river into the hinterland of their Olisa Empire after the outbreak of war.

In addition, in addition to all kinds of anti-landing fortifications on the beachhead, a larger defense and depth fortification system was also built in some important areas where the Daheng people might land, so as to ensure that after the navy and shore fire could not block the landing of the Daheng people, their army units could still rely on these in-depth fortifications to resist.

However, this first point is only ground defense, and when it comes to this step, it means that the Olisa Empire has fallen into a great passive situation of war.

Therefore, the second point about the construction of the navy is more important.

The Orissa Empire still hopes to keep the Great Heng people out of the mainland, so naval construction is also a very important part of their home defense strategy.

They focused on strengthening the construction of coastal defense warships, including torpedo boats, warships of a defensive nature in the near sea, and ocean-going warships.

In addition, they are also preparing a large amount of research and development of mine technology, and are preparing to hoard a large number of mines.

After all, if it is purely a defensive operation, mines are actually more effective than warships, which has been fully proved by the Daheng people in the serial war.

The Great Heng people dropped a large number of mines off the coast of the Bowa military base back then, originally to guard against the Gafia Empire's navy, but the Gafia Empire really didn't dare to come, and the Daheng people's own ships were sunk a lot.

Torpedo boats and mines have been regarded as a sharp weapon for coastal defense by many countries, especially those that do not have the ability to maintain a large fleet and develop advanced main warships.

Not to mention small and medium-sized countries, even major powers generally attach importance to the research and development of these two weapons.

The mine research of the Daheng Empire has always been among the top ranks, and it is also the only country on the Blue Star that has achieved actual results through mines, even if it is its own ship, but it is also a result, which fully reflects the advanced nature of the mines of the Daheng Empire.

At present, there are many varieties of mines in the Daheng Empire, with excellent performance, which can be used in different environments, and are deeply loved by all countries.

In the case of torpedo boats, not only the ships themselves, but also torpedoes are needed.

And this thing is also the traditional advantage project of the Daheng Empire, the A series of torpedo boats of the Daheng Empire, which has been a large number of ordnance products for export over the years.

In particular, the super-armor series torpedo boats that were just launched last autumn attracted a rush to buy from various countries as soon as they were launched, and the traditional military and trade cooperation country of the Daheng Empire, the Orr Kingdom, ordered more than a dozen super-armor series torpedo boats in one go.

Even the newly-born Kingdom of Dynaudio, although it was poor, still had the cheekiness to find another loan from the Daheng Empire to purchase super-armor series torpedo boats.

Other countries are also more or less ordered, so that this super-armor series of torpedo boats has been launched in just half a year, and dozens of orders have been obtained, which does not include the torpedo boat orders ordered by the Daheng Empire itself, because the super-armor series torpedo boats are specialized foreign trade models, with tonnage ranging from more than 300 tons to more than 500 tons.

This kind of torpedo boat is used for ocean-going operations while taking into account the defense of the coastal sea, and it is used as a capital ship in many small countries, and even in medium-sized countries, it is also used as an auxiliary ship for the main warship.

And Dahengren's own torpedo boats are designed separately, because Dahengren's ocean-going lightning strike operations do not use this kind of torpedo boats of several hundred tons, but use destroyers of larger tonnage, and Dahengren's destroyers are more than 1,000 tons.

As for coastal defense, the Daheng people are more inclined to small torpedo boats with only a few tens of tons, and they don't expect them to do anything, just to defend the port.

The reason why the super-armor torpedo boats launched by the Daheng Empire were bought very well when they were first launched is not that the ships themselves are good, in fact, this hull is still improved from the previous A series torpedo boats, whether it is speed or other performance, in fact, it will not be much better than the hulls of torpedo boats produced by other major countries.

What's really good is the torpedo on board.

This thing is carrying a thermodynamic torpedo!

As a representative of the field of military-technical cooperation between the Daheng Empire and the Kekel Empire, the development of thermodynamic torpedo technology is very fast, and the cooperation team of scientists of the two countries has already solved the key technology and successfully tested it in the first place.

When a breakthrough was made in the key technology, the cooperation naturally ended, and the two countries began to go home with the core technology to develop their own thermodynamic torpedoes.

Last year, the Great Heng Empire began to design and produce the first thermodynamic torpedo, called the No. 1 torpedo, which has a diameter of 550 millimeters and a maximum speed of 40 knots.

However, even at a speed of 30 knots, the effective range of this torpedo can still reach 5,000 meters.

The appearance of this torpedo directly led to a major change in torpedo technology in the Daheng Empire, and a large number of cruisers, destroyers and torpedo boats will be replaced with a new generation of torpedoes.

At the same time, this thing is not a classified product, but a product developed in cooperation, but the Kyle Empire also has thermodynamic torpedo technology, and it has also been developed.

In order to grab money, the people of Daheng directly matched this thing on the torpedo boat for export, and before the Kele Empire reacted, they grabbed a large number of orders.

The emergence of this thermodynamic torpedo has directly led to a significant increase in the importance of torpedo boats, destroyers, and other types of ships that use torpedoes as the main striking force.

And this is what really makes the ocean-going lightning strike force of the Great Heng Empire have the ability it should have.

In the past, in fact, many countries, including the Great Heng Empire, did not understand the construction of a bunch of thousands of tons of destroyers by the Great Heng Empire.
