"Chief Engineer Wang!"

"Director Chen!"

"It's ready to go. ”

Xu Ban came over to say hello. The group immediately boarded the boat.

This long-distance sea trial consisted of a small formation of three ships. The flagship is the Jianzhou ship.

The preliminary planned routes are all offshore. South. to the great-mother of the dark sands. Return.

The one-way route is about 3,500 km.

At a constant speed of 40 knots per hour, it takes about 48 hours each way. That is, two days and two nights.

Note that this is a full high speed. There is no stop in between.

If possible, keep the speed higher.

After all, with a driving force of 60,000 horsepower, the speed is definitely more than 40 knots.

Theoretically, it should be possible to maintain a speed of 50 knots for a long time. But you need to test it later.

If the speed of 50 knots is maintained, the time can be reduced to 38 hours. It is shortened by about 10 hours.

The route can also be changed.

It is entirely based on reality.

The Panshi 600 does not need to carry fuel, and the degree of freedom is greatly improved.

As long as you can get the approval of your superiors, even if you can go directly across the Pacific Ocean, all the way to the South Pacific, and then enter the Indian Ocean from southern Australia, it is completely fine.

Even if there are no mechanical problems, it is easy to sail around the world over long distances.

The circumference of the equator is only 40,000 kilometers. The circumnavigation route is about 50,000 kilometers.

At a high speed of 50 knots, it is only 550 hours.

If you work day and night, you won't need it for a month.

"Let's go. ”

"Woo!"

"Woo!"

With Guan Hongru's order, the formation set off.

Head east first, then turn south. It passes through the eastern sea of Treasure Island.

Gradually, the speed of the ship began to climb.

15 knots......

20 knots......

25 knots......

30 knots......

35 knots......

The speed easily reached more than 35 knots.

This is a speed that has been achieved in previous short-haul sea trials. The Rock engine and drivetrain are performing well. Everything is normal.

The purpose of long-distance sea trials is to increase the speed to more than 40 knots and then maintain it for a long time.

The speed continues to increase. Soon it exceeded 40 knots.

The power compartment is normal.

The drivetrain is normal.

The noise of the engine is very low. Only 80 decibels.

For an engine capable of producing super horsepower, 80 decibels is simply an angelic sound.

In the case of a gas turbine, it is running at full speed and the noise is at least 120 decibels or more.

If you are not wearing earplug headgear, you can't get close to it easily.

Because the gas turbine is too loud, it is also easy for the enemy to pick up the sonar signal, thus revealing the whereabouts.

Why was all-electric propulsion invented?

One of the benefits is that the engine noise is reduced.

Now war, discover and destroy. At all times, be careful to hide yourself. The noise of the engine is getting more and more deadly.

If it is 80 decibels of noise, it will be much more difficult for the enemy to capture the sonar signal.

System data shows that the current power output is less than 30,000 horsepower.

In other words, half of the power reserve is still not being used. It is equivalent to an adult who can carry 100 pounds of heavy objects, and only 50 pounds have been moved.

The speed did not continue to increase.

It's not a question of motivation. It's the problem of the ships themselves.

Due to the high speed, the ups and downs of the ship itself are now very large, and the amplitude of the swing from side to side is also relatively large.

The waves that split the bow of the ship hit the deck.

On both sides of the deck, there was not only a splash of water.

However, the speed of the ship was too fast, which caused the waves to surge very much.

This transformation is purely taking into account the power system, and the transformation of other parts has not yet been carried out.

As a result, a large amount of sea water slammed onto the deck, washing it over and over again.

When the ship shook, the water on the deck was thrown several meters away.

Looking at the Qinzhou and Weizhou ships on the left and right sides of the Jianzhou ship, the two sides of the deck are simply waterfalls.

The waves crashed onto the deck and then poured down wildly.

Occasionally, I feel that the Qinzhou ship or the Weizhou ship seem to be drowned by the waves.

Fortunately, Wang Buan was sitting in the command room and felt pretty good.

"How do you feel?" asked Chen Xiangmin in a low voice.

"It's fine. Wang Buan reluctantly responded.

Of course not very good.

Such a big bump. Seasickness at any time.

If it was him before, he would be 100% seasick. I'm afraid that the Jianzhou ship has not yet left the port, and he already needs to be rescued.

Fortunately, the template gene injection was injected, and the physical fitness has improved a lot.

The last time I took a fishing boat, it wasn't so good.

The main thing is the design of the fishing boat, which is based on stability.

And the design of warships is to take into account all kinds of maneuverability. Like dodging torpedoes or something.

Congenitally speaking, small-tonnage warships belong to the type of lively and jumping. The speed is fast, the U-turn is fast, the flexibility is changeable, and the task is wide, so it is naturally not so stable.

Fortunately, after two hours of tossing, I finally got used to it. There was not much discomfort.

It's just a little cool. The whole warship was a splash.

But it was the waves that splashed up, and they were shattered, and they splashed everywhere, and they became a misty patch.

Everyone on the battleship was baptized by the sea.

"Report! We're locked on radar!"

"Report! Radar waves are coming from three o'clock!"

Suddenly, there was a staff report.

However, he was tracked by an unknown submarine.

This is very common.

Every ship in China that goes to sea will be tracked.

Ships, like people's ID cards, have a special electronic signal. Based on this electronic signal, it is possible to deduce which ship it is.

Among the specialized ships of the Navy, there is a type of vessel called an electronic survey ship.

This is a very taboo ship for all ships.

Why?

Because it can depict the identity card of the ship.

It is able to record the operational characteristics of each ship, capture them, and make them into data signals.

In the future, as long as the signal of the characteristics is found, it will be immediately able to determine which ship it belongs to. Which country does it belong to and what are the basic parameters. So that it is clear at a glance and targeted.

For example, at present, the unidentified submarine can be 100% judged to be three warships, including the Jianzhou ship, the Qinzhou ship, and the Weizhou ship.

Because the electronic signals of these three warships have already been recorded in detail by others.

Even if you make a big change, it's hard to change.

"Ignore it. Guan Hongru said calmly.

"They can't catch up. Major Gan Haoyan, the captain of the Jianzhou ship, nodded.

"Chief Engineer Wang, what do you think?" Guan Hongru said suddenly.

"Shake it off. Wang Buan replied.

A submarine wants to track a frigate? just kidding......

If you can run at a high speed of 40 knots, Lao Tzu will have your surname.

The radar system of the Jianzhou ship itself is relatively backward, and the sonar system is not very strong.

It is not possible to judge the exact distance of the unidentified submarine for the time being. It is also impossible to tell which submarine the other side is.

However, judging from the current radar wave intensity, the other side should be 150 kilometers away. And it is on the left side of the Jianzhou ship, that is, at three o'clock on the map.

The structure of the map is up, north, down, south, left, west, right, east. At three o'clock, it was east.

The Jianzhou ship is walking in a straight line. The other side is a diagonal line.

Even at the same speed, the Jianzhou ship can throw off the other party.

Not to mention that the current speed of the Jianzhou ship is as high as 40 knots. It's completely possible to throw off the other party's eight streets.

However......

Wang Buyan has bolder ideas.

Why passively accept it?

Why don't you vote for him?

"I suggest we turn and catch up. Wang Buan added slowly.

"Why?" Guan Hongru asked in a deep voice.

"Come and don't be rude. ”

"Good. ”

Guan Hongru categorically ordered.

The three frigates immediately changed course.

All at a high speed of 40 knots, in the direction of three o'clock in the east.

He has been given great authority to test the performance of the Panshi 600 in all aspects.

Now, it's a great opportunity to test it.

Aren't you 150 km away?

Don't you think you're safe?

Good.

I'll catch up.

Our three frigates deal with you a submarine and don't scare you out of peeing.

You know, the most professional skill of a frigate is to deal with submarines. The anti-aircraft firepower of the Jianzhou may not be good, but the anti-submarine capability is very powerful.

In addition to those blackfish with very advanced performance, ordinary blackfish, when they encounter a frigate, it is a dead end.

Of course, the outbreak of war is impossible. At most, it's just a scare and a scare.

However, as long as you can catch the other party, you will win.

Let's go!

Let's go!

Let's go!

The three frigates made a left turn in unison.

The waves that split at the bow of the boat were even more intense. The foredeck is constantly being scrubbed.

The stern left three long lines of white wavy lines. The waves are constantly surging in both directions. It has not disappeared at the very end of sight.

Whoa!

Whoa!

Chop the waves and move forward bravely!

In an hour, the Jianzhou ship advanced about 70 kilometers.

At this time, the radar of the Jianzhou ship also captured the traces of the other party.

The location of the submarine is just 80 kilometers away.

The other side is still heading west.

Obviously, it has not yet realized the danger.

It probably took it a little lightly, and didn't expect the other party to rush up directly.

The most important thing is that it did not expect that the speed of the Huaxia frigate would be so fast. That's up to 40 knots per hour. It is more than ten knots higher than it.

"Speed up!"

"Speed up!"

Guan Hongru calmly ordered.

The power of the engine continues to increase. The speed increases.

42 knots......

44 knots......

46 knots......

Stabilized for the time being.

After all, 46 knots is already very high.

The previous Jianzhou ship had never run at such a speed. I don't know how mechanical rigidity is.

In case the battleship can't stand it and suddenly falls apart, it's not fun.

There's a term called metal fatigue.

Metal also falls apart.

The plane fell apart and crashed directly.

The warship fell apart, and everyone had to go into the sea to swim en masse.

"Report!

"Report! The target turns to five o'clock!"

"Report!" the target turned to four o'clock. ”

"Report!" the target turned to three o'clock. ”

Soon after, the radar crew discovered that the unidentified submarine had quickly turned around.

Obviously, the other party also sensed that something was wrong.
