Shen Chao didn't let the main gun speak directly, because it was completely unnecessary in this small battlefield. To fight these small warships, which are only two or three hundred meters long at the largest and only the size of two or three aircraft carriers, and have no shields, only need to use secondary guns. There is no need to use a main gun with hundreds of millions of tons of TNT power.

Moreover, the rate of fire of the two main guns on the Budapest is too low, and the attitude of the hull must be finely adjusted to aim, and it is really a cannon to fight mosquitoes when it is used to hit the small fleet in front of you, which is too wasteful and cannot be efficient.

The secondary guns do not have these problems, and the 17 secondary guns on the hull fire at a high frequency and with a wide firing range, they are also easy to adjust.

Although the two indicators of range and firepower output are far from catching up with the two main guns, they are just enough to fight these low-tech worlds.

All 17 secondary guns on the Budapest can accelerate the alloy projectile of the 1.2-kilogram secondary gun to about 20% of the speed of light.

At such a limit, the kinetic energy of the projectile fired by a single round of fire from each secondary turret is equivalent to the energy of a 1 million-ton nuclear weapon. If this kind of fire hits a densely populated area on the ground, it is really not difficult to destroy a small and medium-sized city with a single shot.

However, if you really fire at this peak output, the secondary gun will need a lot of cooling and recharging time. On average, each double-barreled turret fires such a powerful round of fire every half a minute.

Therefore, this method of firing does not provide the continuous fire support that the secondary artillery department should have, and few warship commanders will use it in actual combat.

In order to pursue the density and continuity of firepower, the secondary artillery department usually accelerates the projectile to 10% of the speed of light or less.

Such a low velocity will greatly reduce the range of the secondary gun and the power of a single shell, but the cooldown time of the barrel will be greatly reduced.

This can not only provide continuous firepower to the battleship, but also actually improve the firepower output capacity of the secondary artillery department. Take, for example, the case of accelerating the projectile of the secondary gun to 10% of the speed of light.

At this speed, the kinetic energy carried by the projectile is significantly lower than the previous state of full power. But it will also be equivalent to about one-fifth of the previous one.

The kinetic energy carried by the shells fired by such a round of firing from a double-barreled turret is still equivalent to that of a 230,000-ton nuclear weapon, which is more than 10 times stronger than the nuclear weapons dropped by the US military in Japan that year.

This output is only enough to fight a dozen small civilian ships or pirate ships or space fighters in the Mass Effect world. But put it here. Without the shield as a natural enemy, this output ability is very invincible.

What's more, under such a single-shot output. The firing frequency of the secondary gun can be greatly increased, reaching a rate of fire of 8 rounds per minute, which is quite stable and powerful fire output.

If the muzzle velocity of the projectile is reduced to 5% of the speed of light, the increase in firing frequency will be even more pronounced. Although the kinetic energy of a single turret firing a round of projectiles drops to 60,000 tons, the firing frequency will become 30 rounds per minute, which can be used as a near-fire force.

At this time. The 8 twin turrets on the starboard side are designed to accelerate the shells to 10% of the speed of light, and a total of 16 barrels on the 8 turrets fire shells alternately, and the firing efficiency is also very high.

With the help of precise fire control, the first batch of ultra-high-velocity artillery shells streaked through space, heading straight for a few government warships just 4,000 kilometers away.

It took less than 0.2 seconds for these deadly shells to cross a distance of 4,000 kilometers and hit their respective targets.

Due to the absence of shields, the striking effect of this round of shells was very noticeable. In fact, the shell was already in a semi-liquid and semi-plasma state when it was fired out of the muzzle.

Therefore, although the shells of each secondary cannon are only the size of an apple, there is a high-temperature plasma mass with a diameter of about 4 meters around it when flying.

The ultra-high-velocity liquid projectile penetrated the entire hull almost unhindered, causing only a hole one or two meters wide, but it was the large mass of plasma generated around the shell that really caused heavy damage to the enemy battleship.

The ultra-high-temperature plasma, which was several meters in diameter, did not directly penetrate the armor and hull when it hit the battleship, as the shells they were carrying. Instead, it releases its own powerful heat energy when it hits the target.

Plasma heat release energy with a temperature of millions of degrees is no joke. Each hit produces a dazzling bright light.

In the process of violent energy release, a large hole with a diameter of more than ten meters will immediately appear on the armor of the enemy ship that is up to 3 meters thick! And this kind of thing is repeated on many battleships that have been hit.

In just the first round of shelling, they knocked out the combat capability of the three heavy warships on the opposite side, and one of them was very unlucky, maybe it hit the reactor or the weapons depot, and it exploded directly into several sections.

The few ships that had not yet been destroyed were also immobile, and fell silent with several large holes of more than ten meters on their bodies. This is not surprising, although the first round of hits were all heavy warships, but the opponent's armor level is obviously not high. Can't block the attack.

Shen Chao didn't think it was strange to them at this result, but the two sides who were fighting were dumbfounded. Immediately there was a noise in the communication channels of the government fleet.

At the same time, the captains of each ship ordered their subordinates to turn up the detection equipment to the maximum power to find out where the unparalleled round of shelling just now came from.

The rebels reacted similarly, and after a brief moment of shock, they searched for the area at full speed, looking for who was supporting them.

The efficiency of the junior officers on both sides was undoubtedly very high, and it only took a few seconds to spot the Budapest on one side of the battlefield, but before either of them could figure out what was going on, the second round of shelling of the Budapest came.

After a few seconds of cooling, charging, and calibration, this round of shelling was much more ferocious than the first one. The first round of shelling just now was very much on the defensive capability of the enemy warships, so the firepower was concentrated on the four battleships.

This time, however, the secondary artillery division, which had figured out the actual defensive capability of the enemy's armor, no longer concentrated its firepower on a small number of enemy ships, but aimed at different targets to attack.

With the full cooperation of the auxiliary artillery department and the fire control group, this round of shelling immediately knocked out seven of the opponent's warships, and two of the smaller tonnage warships were even more tragically blown up.

At this stage of the battle, anyone can see that the victory or defeat depends on this new super powerful battleship, and this unknown warship seems to be an ally of the rebels, so it is very clear what everyone should do next.

Under this basic consensus, both the rebel and government fleets immediately tried to contact the Budapest, the rebels wanted to confirm the identity of such an "ally", and several captains of the government forces wanted to surrender.

For these captains, the dignity or honor of the Federation is far less important than their own lives, because unlike the well-organized interstellar navies of most planes.

Almost all of the high-ranking positions in the Federation fleet of this plane are bought by the children of the gate lords with backgrounds for a large price. More than half of the senior officers in the fleet do not know much about military affairs, and the few who understand military affairs do not have sufficient backgrounds, so they cannot stand on the field.

That's why Roy used to always say that the federal government of his parent plane was extremely corrupt. Even the military is like this, and the corruption of government agencies can be imagined.

It is no wonder that replicants have been able to survive in this remote galaxy for so long, their opponents have strong technical equipment and industrial strength, but they do not have basic military literacy and will to fight......

Back on the battlefield, both sides of the message were clearly a little slower. As soon as their message was sent, the third round of shelling of the Budapest arrived as scheduled.

This round of shelling knocked out several government warships. The young masters of the government army who paid to become commanders were about to cry when they saw this, and it was only then that the communications department of the Budapest received a telegram from the other party.

"Sir, we have just received two clear-code messages, one of which is from our belligerents, a surrender message......" In the CIC, an officer on duty sent the original text of the other party's message while reporting.

The message from the government fleet was simple, with only one sentence: "To the unknown warship, please stop shooting, we surrender unconditionally......"

After seeing such a message, Shen Chao immediately stopped the secondary artillery department, which was preparing for the fourth round of shelling, and asked the communications department to send a call back.

The content of his call back is also very simple, indicating his identity and accepting the surrender of the other party. After all, they are here to recruit people this time, not specifically to fight, and the advantages of receiving this group of prisoners outweigh the disadvantages for them.

However, although he accepted the other party's surrender, Shen Chao also ordered the other party to shut down the fusion reactors of all warships in the message. All personnel laid down their arms and prepared to accept their men on board the ship for surrender.

These conditions are all prerequisites for the victorious side to accept the enemy's surrender in interstellar warfare, which is common sense, and it is impossible for the other side not to accept it if they want to live. So Shen Chao was not worried at all that the other party would not agree.

It was only after arranging the message that he began to read the message from the rebels, which was again brief, but asked who they were and why they were helping them.

"Roy, you can communicate with them......" As soon as Shen Chao saw this message, he handed the intercom to Roy and asked him to handle it. Shen Chao himself was responsible for arranging the reception of prisoners and the opposing warship.

Shen Chao himself didn't know anyone in the rebels, so letting Roy be in charge of the negotiations was undoubtedly the best choice. His conjecture proved to be fine, and while he arranged for the Marines to receive prisoners of war in batches, Roy also got in touch with his fellow rebels and quickly learned what had happened.
