"Yes, yes!" Xiao Bingyang nodded hurriedly.

"What are you doing in a daze? Wait for me to invite you! Zhan Changsheng said with a black face.

Xiao Bingyang spread out the navigation chart, sat down, picked up a ruler and a pen, and began to calculate according to the data provided by Chang Sheng, "The azimuth is two, four, three, the distance is eighty chains, the enemy direction is zero three zero, and the enemy speed is eighteen knots." I'm going to 280, I'm going to speed six knots ......" as he said and calculated in his notebook.

Zhan Changsheng lowered his eyes and looked at him, dancing with dragons and phoenixes in his notebook, and muttered in his heart: Still a ruthless old man! If you come up with this question, you probably have to count this kid down.

While his thoughts were churning, Xiao Bingyang stood up and said, "Report, the calculation is complete, the torpedo has a range of 4,500 meters, and the hit angle is 37 degrees." ”

Zhan Changsheng reached out and took his calculation process, this kid is not bad! "Now that it's calculated, let's follow the order!"

Xiao Bingyang immediately gave orders to his comrades through the communication system.

As a result, the torpedo was jammed, and Chang Ning and Luo Zhongxin were dumbfounded all of a sudden.

"How so?" Chang Ning was so anxious that he was sweating down, "What should I do?" He rubbed his hands together anxiously.

"Don't stand stupid, check it out!" Luo Zhongxin stabilized his mind and said calmly.

"Oh! Oh! Chang Ning nodded busily.

began to look for the reason with Luo Zhongxin, and the two of them carefully checked it, looking at the note stuffed in the corners.

Chang Ning opened it and said, "The reason was found, it turned out that the pressure of the launch cylinder was too low, which caused the release valve to open in advance." The torpedo was just stuck. ”

"How so?" Luo Zhongxin said with a frown.

"How could this happen?" Chang Ning said in disbelief, "I checked." ”

"It's because we didn't check it carefully enough." Luo Zhongxin said regretfully, "The pre-launch preparations are not in place. ”

What else can I do? Follow the operation manual and re-rigorous operation!

……

After an exercise, all the personnel in the boat collapsed, and everyone gathered together to pour bitter water.

"I cleared the customs without a hitch!" There was joy in the tone.

"I've been pitted this time." The tone was not frustrated, "You know what's wrong, he deliberately pulled out the thread, resulting in poor contact, I'm stupid, I thought there was something wrong with the machine, so I checked it out!" It's just that there is no 'rummaging'. Don't abuse us like this! ”

"Fortunately, I was prepared! I never thought that Director Zhan was so kind. ”

"I thought about it too, but this problem is so strange that you can't guard against it."

"Looks like it's going to kill us to the beat!"

"You say, what does the war director's brain think, how can he think of such crooked ideas!"

"The soldiers are coming, the water is coming, I tell you! On this issue, we must not admit defeat. ”

As they were spitting out bitterness, the devil-like voice of Zhan Changsheng came from the loudspeaker, "All attention, all attention." Next, you will conduct a simulated confrontation drill, and this exercise will be used as a real combat drill to complete the attack on the enemy's target. Make every effort to break through all traps, during the exercise, Luo Zhongxin will be the acting captain, and I will let people tell you about the deployment and position of the other crew. After a pause, a low voice sounded again, "I wish you all the best until the moment the submarine hatch opens." ”

Soon someone handed the note to Luo Zhongxin, and he looked at the note and began to assign deployment positions, deputy captain, steer, navigation station, sonar, torpedo operation......

After receiving the order, everyone took their places with their people.

Luo Zhongxin asked calmly, "Each unit reports the data situation. ”

"Yes!"

"Report the captain, the current depth is 100 meters, the speed is 5 knots, and the course is 110"

Luo Zhongxin heard the words, "Yes, keep the course." ”

"Yes!"

"Report, sonar finds unidentified target."

"Report, pulse bearing." Luo Zhongxin asked.

"Bearing, zero six, decreasing."

"Yes, analyze the underwater acoustic environment."

……

Suddenly, there was a violent tremor, and the earth felt like the mountains were shaking.

"What's going on?"

"Are we being attacked?"

"The sonar didn't detect a high-speed moving target, huh?"

"Whew! That's good, I thought the enemy ships were coming. Chang Ning let out a sigh of relief.

As soon as the words fell, Luo Zhongxin glared at him, which really disturbed the morale of the army.

"It must be caused by the currents, right?"

"The inertial navigation system shows that our boat is deflecting to the left."

"It was probably a rapids coming from the sea, and it was very powerful, and it took us some distance."

"Report, on the left side of our boat, there is a large area of contact, which is approaching." Sonar detection reports.

"Corrected course...... Luo Zhongxin strode to the vicinity of the chart after giving the order.

"The submarine is still moving on the left, but the stern has left the ridge on the left." Xiao Bingyang looked at him and said.

"Pay attention to the change in the density of the sea." Luo Zhongxin stared at the chart and said, straightened up, looked at the sonar and said, "The sonar reports the target's situation." ”

"Reporting, low signal-to-noise ratio, unstable tracking."

Xiao Bingyang pointed to the chart and said, "Captain, we are in this position now. Looking up at him, he said, "The underwater acoustic environment is very unfavorable for our boat to maneuver. "I suggest continuing to dive and using the H-shaped underwater acoustic environment to carry out a torpedo attack while our boat itself is hidden, and the probability of hitting the target will be greatly increased." ”

"Xiao Bingyang, what you said is just speculation, and there is no scientific basis. I can't take your speculation as a scientific assertion. Luo Zhongxin immediately retorted when he heard this, took a deep breath and said, "This is related to the lives of all the people in the boat." ”

"These are things that I've verified, and they're not made in the ass." Xiao Bingyang said with a serious face.

"Captain, I think we can take his plan." Chang Ning looked at Luo Zhongxin and said.

"The marine underwater acoustic environment is complex and ever-changing. In the actual detection of submarines, the accuracy and real-time performance of sound field calculation are quite high. Luo Zhongxin said very steadily, "If we continue to dive and lose the target, the mission will be a complete failure." ”

Xiao Bingyang shook his head slightly when he heard this, "To fight a war, we must first protect ourselves, we can't do things that kill one thousand enemies and lose eight hundred." ”

Subtext, the enemy fights, we can't afford it! We can't lose all our money.

"Sonar detects the position of enemy ships." Luo Zhongxin ordered directly.

Xiao Bingyang threw the pen in his hand directly onto the table with a little emotion.

Report. The target azimuth is 120, and the speed is 5 knots. ”

"Yes!" Luo Zhongxin then ordered, "The No. 1 and No. 2 torpedoes are ready to be fired. ”

"Torpedo No. 1 and No. 2 are ready to launch tubes. Unlock at a distance of 2,000 meters, two shots at an interval of five seconds, and a divergence angle of 15 degrees. ”

"Launch the torpedo." Luo Zhongxin ordered.

"Yes! One and two torpedo tubes were launched. ”
