The core of every squadron is a cruiser.

Equipped with five destroyers, thirteen frigates, and three torpedo boats.

Each ship has different combat capabilities and operational functionality.

The interstellar age and the ancient naval warfare era are the same in terms of the functionality, naming and use of ships.

Like frigates, their main function is to provide escort for large ships, because they are small in size and highly maneuverable, and can patrol flexibly around the fleet.

Timely discover and drive away enemy small ships approaching, establish defense lines at medium and short ranges, and intercept enemy carrier-based aircraft, missiles, and even mechas.

This type of interception is diverse and can use ship-borne weapons, such as the main gun at the bow, as well as small and medium-sized energy cannons and kinetic cannons.

Intercept incoming carrier-based aircraft, missiles, and space torpedoes.

What if these weapons cannot intercept? Then these frigates have one last way, which is to rely on their own ships to intercept.

Whether it is the main guns of the enemy's large ships, the concentrated fire of many weapons, or even the assault of mechas.

They can use their own ships to intercept and sacrifice themselves to protect large ships.

However, in most cases, frigates equipped with a large number of small and medium-sized weapons and anti-missile missiles can perform protection tasks well.

In the past, when Li Xin had only a few ships, he used frigates as main ships. This was a helpless measure.

Now with stronger destroyers and cruisers, the chances of frigates being at the forefront of the attack will only become less and less.

Even for a long time to come, the number of frigates in the fleet will continue to decrease.

Instead, they continued to add other medium and large ships.

After all, the frigate was a sweetheart to Li Xin before, but when the cruiser appeared, the frigate became Mrs. Niu.

Who doesn't like big?

Destroyers have more functions, because destroyers are the main offensive warships, at least in the interstellar era.

The main guns are more aggressive, and equipped with advanced radar, the ships can reach a range of about 800 meters.

It can carry a lot of equipment and modules, and can execute more diverse combat modes to meet the needs of various conflicts.

It can not only perform medium-range escort missions, but also take the initiative to attack, tearing through the enemy's frigate defense line and opening a gap for subsequent carrier-based aircraft and mecha units.

It has many functions and is a complete panacea. In many human fleets, destroyers are the most numerous.

Finally, there is the current core of the fleet, the cruiser.

As an entry-level large ship, it is not as good as the others but better than the others. The number of cruisers in a normal human fleet is not large enough.

But this does not mean that he is not strong, it’s just that his strategic focus is different.

The firepower of a cruiser is very strong, at least much stronger than that of a destroyer.

After all, the salvo stern at the stern of the cruiser is a medium-sized weapon among the five weapon slots for the cruiser, but for the destroyer, it is already a main gun-level weapon.

Not to mention the huge cannon on the bow of the ship, the five large main guns are even more powerful.

This type of main gun is also a secondary main weapon on battleships.

The hangar can carry a large number of carrier-based aircraft and mecha units, and has many combat uses.

Cruisers not only have good offensive capabilities, but also good defensive capabilities. The hangar can not only carry offensive carrier-based aircraft and mecha units, but also a large number of missiles and medium- and short-range defensive weapons.

In a normal human fleet, if the battleship is an officer, then the cruiser is a sword-wielding guard who can fight and resist, the destroyer is a fast-running cavalry, and the frigate is a miscellaneous soldier such as a sword and shield soldier.

As for the larger ones, such as the Dreadnought flagship, the aircraft carrier flagship, and even the more powerful Titan flagship, they belong to the level of the central army commander.

This exercise was mainly to practice the coordination between fleets, and only at the end did the cruisers, as the main ships, open fire.

In space combat, the distance between ships cannot be too close.

The distance between each ship is hundreds of kilometers, which is the normal distance. Sometimes it may be farther, reaching thousands of kilometers.

The reason is very simple. First, the ships have a long range, and second, they are very fast.

If the distance between the ships is only a few kilometers or more than ten kilometers, it is basically equivalent to flying side by side.

The general flying speed of ships can reach more than 200,000 kilometers per hour.

It can travel dozens of kilometers in a second. If the distance is close, you can easily hit it.

In this exercise, the distance between the frigates is about one thousand kilometers.

In contrast, as a medium-range defense line, the distance between the frigate and the cruiser is relatively far, about 50,000 to 100,000 kilometers.

At this distance, the main gun can play a defensive role and attack the enemy.

The destroyer runs very fast and plays the role of a striker.

The cruisers were stationed at the rear, and the first to be dispatched were the carrier-based aircraft. As the engine rooms of the five cruisers opened, one carrier-based aircraft after another was launched.

These carrier-based aircraft are generally much faster and can approach the target at a faster speed.

Each cruiser launched 120 carrier-based aircraft and headed straight for the target.

The military attaché of the Yaru Alliance's embassy had unconsciously approached the porthole at the bow of the ship.

He looked at these carrier-based aircraft, carefully observing their shapes, engines, speeds, and guessing their attack methods.

The ambassador walked up behind him and whispered, "Pay attention to your posture. What's wrong with you?!"

The military attaché then realized that he had walked so far without realizing it and was almost leaning against the porthole.

The human diplomat, a psychic, walked over and handed a sighting device to the military attaché. He smiled and said, "Use this to see. What's next is interesting."

The military attaché smiled awkwardly. They didn't dare to bring these with them this time, so they quickly took them and continued to observe the cruiser impatiently.

Ambassador Yaru, who was standing by, felt that his shell was about to change color out of embarrassment.

At this time, the hangars of several other cruisers opened and mechas were ejected from them.

After these Ranger mechas popped out and flew a short distance, they opened the subspace and jumped almost at the same time.

When it appeared again, it had already arrived near the exercise target.

Military Officer Yaru, upon seeing this, exclaimed uncontrollably, "Oh, Mother Goddess! It's a mecha!"
