Anti-daoban chapter, look after seven o'clock. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"The sonar found that in the port 2-1-0 direction, fifteen nautical miles, there was a noise from a low-speed propeller." The sonar soldier reported.

The TR-1700 submarine uses the DUUX-5 type of Thomson Sintra in France, which is a very good passive sonar with long detection distance and high accuracy.

Hearing the presence of ships ahead, Mustafa came to the spirit: "Ascend to periscope depth, pay attention, the attack drill begins." ”

The steering wheel operator controls the steering gear in his hand, and the two horizontal rudders on the upper part of the control tower and the tail of the submarine begin to move, the bow of the submarine begins to lift, and the submarine slowly rises in the water.

At a depth of almost ten metres, the steering driver stabilized the hull and regained his balance again.

"Periscope depth has been reached."

"Ascend periscope." Mustafa said.

With the sound of an electric motor, the periscope was slowly raised, revealing the surface of the sea.

A seabird, already a little tired from flying on the surface of the sea, suddenly saw something on the surface of the sea that was breaking the waves, and it seemed to be very steady, it chirped, and landed on it in a graceful posture.

After standing firm, the seabird had a relatively high IQ, and it had noticed that there was something unusual about this thing under its feet, so it lowered its head and looked curiously at the barrel of the periscope.

There was a multicolored glow inside, which filled it with excitement.

Mustafa expertly flicked the two armrests of the periscope, and his eyes were glued to the eyepieces.

What a big ship! Mustafa rubbed his eyes, that behemoth was about to occupy the entire field of view of the periscope!

"Target bearing, 2-1-0, distance, five nautical miles..."Mustafa read the data from the scribe in the periscope, but before he could finish speaking, Leo, the German adviser next to him, stood up, pushed Mustafa away, and took a look inside the periscope himself.

Just now, the sonar soldier reported that it was fifteen nautical miles, but now the captain personally inspected it, and it turned out to be five nautical miles, which is a total of five minutes, and he actually walked ten nautical miles, how is that possible? One of them must be wrong, even if it's a high-speed speedboat, I'm afraid it can't fly that fast, right?

He glanced inside the periscope and couldn't help but want to be angry, there was a seabird magnified countless times in it, and innocent eyes were staring at him, what kind of target was there! This is a seabird that landed on the top of the periscope! He couldn't laugh or cry, and the odds were very small.

"That's not the target, it's a seabird that landed on the periscope!" If he had spoken the language, he would have scolded in German a long time ago, he was so stupid!

Mustafa took it, looked at it again, and finally saw it clearly.

"Turn the periscope three hundred and sixty degrees, or lower it and rise again, and chase away the seabirds." Leo said.

Although the translator had not yet translated Leo's words, Mustafa already knew what to do, and he knew that it was his own mistake, so he used his two arms to drive the periscope and rotate it for a circle.

The seabird felt a little unsteady about the thing beneath it, but it still didn't want to leave.

In desperation, Mustafa had no choice but to lower the periscope.

The seabird's feet suddenly flooded, and finally realized that this thing was indeed unreliable, spread its wings, and flew back into the sky.

In war, there will be all kinds of accidental factors, advanced equipment, will be doomed, such as what happened to Mustafa today, periscopes are patronized by seabirds, for example, when the tank crew is charging quickly through the mud, a piece of mud splashes up, covering the advanced sighting equipment...

Mustafa didn't have time to think about it so much, he didn't feel ashamed, they are all novices, and it is possible to make these mistakes, but such a mistake will only be made once at most!

The periscope was raised again, and the surrounding vision widened, and Mustafa rotated the periscope for half a circle to spot the target reported by the sonar crew, which was a huge ro-ro ship emitting black smoke.

I'll take you to a walkthrough!

"The left rudder is full, ready to occupy the firing position."

"Forward two, right hand rudder three, active sonar ready to detect data."

The German-made CSU-3 search/attack sonar was ready, and then two sonar waves were fired at the imaginary enemy on the surface.

The submarine will be equipped with two kinds of sonar, active sonar and passive sonar, passive sonar is a one-wave receiver, relatively small power, but very sensitive, used to send all the sound wave data heard to the computer, which will analyze and determine suspicious targets against the marine life in the database and the sound wave characteristics of ships of other countries, and also rely on the ears of sonar soldiers. Towed volume sonar is more sensitive.

The active sonar is in the passive sonar intercepts the basic information of the enemy ship's position, sea navigation, speed and so on, and only turns on after the submarine of the local submarine successfully enters the fish launch position, and the active sonar irradiates the enemy ship, the computer will input the data of the active sonar irradiating the enemy ship into the torpedo, and then use the torpedo to attack the target. For example, passive sonar is the search function of the radar, and active sonar is the locking function of the radar.

"Smack, smack." Two sound waves hit the hull of the ro-ro ship, and the crew was nervous, could it be that they had hit something?

They didn't know that if it was in war, it would mean that they were going to die soon.

"Drill complete." Mustafa finally shouted that if it was in the middle of the war, then his next order would be to launch a torpedo!

Looking at these skillful steps, Leo was quite satisfied: "In war, using merchant ships to conceal themselves is a common means used by submarines, and our next subject is to practice sailing under the merchant ships, which is a slow ship, and we can use batteries to keep up with it at an economic speed." Leo continued.

Getting under the belly of a merchant ship? That requires more courage and operational ability! After listening to the translator's words, Mustafa said with a heartfelt voice: "Okay, let's follow immediately." ”

Colorful, everyone is full of energy, even if they are lying in bed, they are thinking about the operation of the submarine.

The submarine forces of the Iraqi Navy have begun to grow slowly.

……

Taha thought about Kusai beside him, could it be him?

No, probably not. Taha immediately denied this idea in his heart, if it was Qusai's doing, how could he do such an obvious thing with Qusai's cleverness? Let the poison dissipate first, and then increase it, if he did it, then the concentration of the venom would not be reduced at all. Moreover, he will not bring himself here at this moment, so if someone really did it, then this person will definitely not be assigned by Qusay.

Well, most likely, I'm afraid it's the woman I saw just now, the kind of expression that Qusay just now, it's obvious that the woman has been fully trusted by Qusay, although only from the crook of that finger, it's a little too arbitrary, but, if it's really the same as her own inference, if she poisoned not only the president, but also Qusay...

Thinking of this, Taha was already shocked into a cold sweat in his heart.

It seems that it is time to remind Qusay and let him be on guard, if according to President Saddam's character, whether there is a problem or not, he will be eliminated, but this Qusay seems to be more merciful.
