At this moment, the phone on Yu Yifeng's power armor suddenly rang, and he glanced at it, it was from the Ministry of Security. Ｘ

He didn't dare to slack off, and immediately connected: "I'm Yu Yifeng, what's the problem?" ”

An eager female voice came from the opposite side: "Captain, the first batch of frigates has been built and will soon enter the test flight stage, Minister Xu invites you to come and visit......"

"Oh, and there are some Deep Space weapons and equipment testing ......," the female clerk said in a few words.

Yu Yifeng's heart moved, has the third-generation frigate been built? And weapons and equipment are also being tested today? He had a faint impression that he might have been negligent because he had asked for too many things recently.

It's a big deal, check it out! Yu Yifeng still has the usual crisp style, and hurriedly answered a few calls on the phone.

After a quick inspection of the material warehouse, they didn't find anything unusual, and immediately turned around and walked out.

"Let's go, let's go to the military zone and see the new generation of warships! The first test is conducted today. He said to a few assistants, thinking that he was fortunate to have recruited a few strong young men.

Otherwise, for ordinary people, running around all day long, patrolling various places, will paralyze their legs......

Yuriko is still one of his assistants, and although she is smart and capable, she is not suitable for this kind of errand work.

If you really take it out and run around, it's too inconsiderate for women.

"Ah, really! A new type of corvette? I've heard that one of them is a streamlined style that can be fired with a railgun! It can enter the planet's atmosphere at a very high speed......"

Xiao Yu beside him shouted excitedly, it seemed that he was a proper military fan.

The others also discussed it enthusiastically. Yu Yifeng smiled in his heart, being young is good, it is energetic!

They take a maglev elevator and return to the regular gravity zone. However, he didn't take off the gravity armor, but directly got on a maglev train and drove towards the periphery of the Noah.

It took about half an hour for the group to finally arrive at the military area of the Deep Space, where four or five hundred staff members were busy.

Deep Space is the equivalent of an aircraft carrier. Smaller ships are stored inside the Deep Space, and larger ones are mounted around the Deep Space.

Yu Yifeng saw old acquaintances such as Xu Yunjin and Zhao Yao here, and also saw his wife Yuriko, who was the main designer of the new generation of warships.

However, the two of them just looked at each other from a distance and did not speak.

Not counting the huge Deep Space for the time being, these spaceships are the third generation of human space warships.

The first generation was the A001 to A003 models developed by Dr. Romon and the second generation of spacecraft was developed by the Knicks to transport space supplies......

Time flies, and now it's the third generation...... Better performance and better performance.

The third generation of ships, mainly for combat purposes, of course, not one, but three!

The first type of space battleship, as Xiao Yu said, is called "Yuyan". It is relatively small, only more than 20 meters long, and looks light like a swallow.

It has a pointed front, very short wings, and a beautifully streamlined model, which is more beautiful and generous than the previous two generations.

Of course, this beauty is not for the sake of looking good, but to reduce atmospheric friction!

The "Yuyan" spacecraft can fly at high speed in an atmospheric environment and is an alternative nuclear-powered aircraft.

If the miniaturization of nuclear fusion cannot be achieved, it is already ...... The pinnacle of fission energy!

While flying in the atmosphere, another nuclear reactor inside Yuyan was activated, heating the liquid metal around the core. The high-velocity gas stream is then brought into contact with the hot liquid metal. As a result, the air flow becomes a high-temperature, high-pressure gas, which is then diverted to the booster turbines of the individual engines, and finally the high-temperature gas is ejected to produce the rear thrust. ”

A staff member stands at the front and explains how the engine works.

Nuclear-powered aircraft, the black technology of the previous earth era, the modern conventional technology.

"Yuyan" can achieve an acceleration of 3 g under the earth's atmospheric pressure, and the maximum speed can reach 20 times the speed of sound!

In the stratosphere, where the air is rare, it can reach 40 times the speed of sound!

And in space, with its own engine alone, it can reach up to 1.6 thousandths of the speed of light! If fired from the mothership's electromagnetic cannon, the initial velocity can reach one-fiftieth of the speed of light!

The second type of frigate is relatively large, probably more than three hundred meters long, and compared with the "Yuyan", it is like a hill.

Its name is ...... "Leviathan"!

Yu Yifeng walked to the front of a "Leviathan" frigate and looked at it carefully. Part of the hull is made of nanomaterials, and the walls are very thin, only a few millimeters thick.

So the whole ship is not very heavy, and it looks a little weak. But when you touch it with your hands, you can feel the hardness and toughness in it.

"If our nanotechnology could go further, this spacecraft would be lighter and more massive. This is also the trend of the future, the lower mass, which is very helpful in increasing the maneuverability of the ship......" Yuriko walked over and whispered.

With a length of three hundred meters, the "Leviathan" is already a small, fully equipped base.

If there is enough energy, it can also forcibly land on an atmospheric planet with a comparable gravity of the earth and fight in the atmosphere.

It is loaded with more missiles, energy and firepower than the "Yuyan", and is even equipped with several heavy laser weapons!

"But this size is still a bit embarrassing, you can't build the smallest fusion reactor, and you still can't use fusion power...... Unless we achieve the miniaturization of nuclear fusion. Yuriko shook her head.

But Yu Yifeng is very satisfied, the length of more than 300 meters is equivalent to an aircraft carrier on the earth!

This is a space aircraft carrier, how can he not be satisfied with the design and manufacture of it in just one year? The difficulty of opening in the water and flying in the sky is completely two orders of magnitude.

It can even be illustrated...... This kind of spaceship can be mass-produced for the new human civilization!

In this way, during the discussion, the first test began, and a "Leviathan" and several "Yuyan" flew out quickly.

Powered by the ion engine, in less than a minute, people can only see a few tiny blue dots of light, like stars in the Milky Way. Although they are not visible to the naked eye, they can be easily detected by the radar and astronomical observation system of the Deep Sky.

The figures of all the spaceships are displayed on the big screen, "Yuyan" is like a real swallow, agile and unrestrained, and "Leviathan" looks much thicker. So both types of ships have their own characteristics.

It's not just flight tests, a large number of metal targets have been placed on the GB131 beforehand to test the weapon system.

"Yuyan" is loaded with small nuclear bombs, which are too many made by humans, and there is almost no need to test, just a few empty bombs are fired at random. Therefore, the "Leviathan" is the main test subject, and the frequency of the heavy laser loaded in it is about three rounds per second.

As long as the shot goes down, tens of thousands of kilometers away, the bull's-eye the size of a car explodes like fireworks, directly melting into shiny molten steel.

"This heavy laser weapon can easily penetrate a three-meter-thick steel plate! However, the energy consumption is relatively large, so the frequency is not high. ”

"The accuracy is still ......"

This was followed by the test of a light laser, which is often used to intercept enemy shells as a defense mechanism.

Deep Space spat out a large amount of aerogel at 15 times the speed of sound and flew towards the test spacecraft. At a distance of 1000 km from the ship, they were automatically recognized by the computer, and light lasers began to be ejected.

Dark red flames appeared in space, and many aerogels were intercepted and destroyed by light lasers.

Immediately afterward, Deep Space increased the spray speed of aerogel.

"15 times the speed of sound, low-frequency attacks can be intercepted almost 100%."

"The 20x sonic attack test is on."

"30x Sonic Test ......"

"High-density electronic interference turns on ......"

As the test conditions became more demanding, the spacecraft interception system began to be overwhelmed, and the 100% interception rate no longer existed. Yu Yifeng also squinted his eyes and stared at the screen carefully.

The Leviathan has a higher rating, and although it is larger, it is also less vulnerable to being hit because of the more powerful interception system.

At the end of the day, the data is listed on the screen.

This test is to find out the flaws of the new generation of warships, and it is impossible to be perfect.

In terms of specific performance, their performance is already more than 80% higher than that of second-generation spacecraft.

This also represents the technological progress of humanity!

It even means...... It is very difficult for the weapons of a low-level civilization to threaten a human ship!

Many people applauded excitedly,
