Chapter 812 Urgent Mission!
At 10:27 in the morning, at the pier of the Smuggling and Crime Investigation Bureau of Qidao Island.

Two brand-new new anti-smuggling boats are berthed on both sides of the anti-smuggling wharf barge. The hull is slender and streamlined from bow to stern, and the net water resistance is greatly reduced compared with typical deep V-shaped boats.

After six consecutive days of trial voyage, it can be felt that the bottom of the boat will generate a large dynamic lift when sailing at medium and low speeds, and the resistance is basically similar to that of the round bilge boats previously equipped by Qidao counterparts.

Due to the long knuckle line, V-shaped cross-section, small waterline entry angle, large lateral slope angle at the bottom of the stern boat, and suitable appendage designs such as long tail fins and bilge keels, it has excellent seakeeping performance. very good.

The matching of the propellers of the ship is also very good. The design did not pursue the maximum still water speed at the design displacement, but left a large power reserve of the main engine under the premise of meeting the speed index proposed in the design task book.This ensures that when it is loaded with the maximum displacement, the main engine can still run to the highest speed, while the speed of the boat only drops by about 0.5 knots.

The manoeuvrability is also remarkable, stable when turning at high speed, the heel angle is small, and the turning radius is only 5.5 times the length of the boat.

What's more, it has a beautiful shape and clean lines!
The front wall of the superstructure is arc-shaped, and a truss-type four-legged mast is used. The front deck is equipped with a cannon, and the rear deck is equipped with a motorboat and davit. The skylight of the auxiliary engine room is opened in the davit of the motorboat. Let the rear deck have a larger activity space.

All in all, the deck layout is neat, compact and well-proportioned.

The side silhouette of the whole boat is both beautiful and neat, and has the majesty of a warship.

The shipyard helped to print the names and hull numbers of the boats. The one equipped for Jiangcheng Customs is China Customs 823, and the one equipped for Binjiang Customs is China Customs 825.

Although it was not named China Customs 001, Han Yu still loves China Customs 825. As soon as he arrived at Qidao, he moved his luggage to the boat and has been living on the boat these days.

He regards the boat as his home, and anti-smuggling team members such as Guo Weitao, Xiao Gong, and Jiang Shengqi naturally also live on the boat.Deputy Director Li of Jiangcheng Customs who led the team to receive the two anti-smuggling boats could only live on the shore alone, and was very embarrassed.

That's right, the customs leader led the team to receive the equipment, and the two anti-smuggling boats belonged to the customs equipment!

Because of this, all anti-smuggling officers on the water, including Han Yu, belong to the Smuggling Crime Investigation Bureau in name, but actually have dual identities of customs officers and anti-smuggling police.

According to the original plan, the sea trial will take half a month.

However, plans are always inferior to change.

At around 9:[-] this morning, Deputy Commissioner Li and Han Yu received orders from the General Administration of Customs, the Provincial Military Region, and the Donghai Base of the East China Sea Fleet almost at the same time.

The only difference is that the order from the General Administration is conveyed through the Customs of Chidao.

Orders from the provincial military region and the East China Sea base were conveyed through the Beihai Fleet's Qidao Base Command.

As soon as Deputy Chief Li received the order, he immediately went to the shipyard to go through the handover procedures in advance, while Han Yu hurriedly called all the crew of the two anti-smuggling boats and the accompanying armed police officers and soldiers for a meeting.

There are more than 50 people in total, and the command cabin of the anti-smuggling boat cannot be crowded, so they can only borrow the conference room of the same team in Qidao.

In the morning, two cars came in a row, and two groups of people looked more serious than the other.

Guo Weitao, Jiang Shengqi and the others not only saw that something big was going on, they could even feel the tense atmosphere.Just when they were secretly guessing what happened, Han Yu gave a dry cough and said, "Comrades, the superior has assigned us an urgent task, and we will conduct the rest of the sea trials at sea."

"Secretary Han, you mean we are going to return early?"

"To be precise, we set sail ahead of time, and the first voyage is the first battle. This is the trust of our superiors, and it is the glory of our 823 and 825 boats!"

"Secretary Han, what mission?" Captain Liu of Boat 823 couldn't help asking.

"The superior requires strict confidentiality. The specific tasks to be performed will not be announced until after setting sail."

Han Yu took out his mobile phone and put it on the podium, looked around at everyone and said, "Now, please hand in your mobile phones and pagers. The 823 boat will be kept by Li Guan, and Li Guan will help everyone bring it back to Jiangcheng. The 825 boat will be handed over to Zhang Xiaojun." The platoon leader reported to the management, and the platoon leader Zhang Xiaojun took him back to Binjiang."

It is normal to hand in cellphones and pagers before performing tasks, and everyone has no objection, so they quickly took out their cellphones or pagers, lined up and put them on the podium.

Zhang Xiaojun, the leader of the armed police platoon, had a big head, and asked with a bitter face: "Secretary Han, you mean that we will not participate in the operation, and we will go back to Binjiang first?"

"Yes."

"Why, why didn't you bring us with you at the critical moment? You didn't say that before you came!"

I brought them here before, mainly because I wanted to take advantage of the opportunity of trial voyage and return voyage to let them experience the work and life at sea.

In fact, half of this goal has been achieved. In the past few days, when the anti-smuggling boats sailed on sea trials, the swing range was much larger than that on the river.

Especially the day before yesterday, when the weather was bad, the sea was windy and the waves were rough, and the anti-smuggling boat swayed from side to side at a height of more than 30 degrees. Guo Weitao, Xiao Gong, the two old marine policemen, Jiang Shengqi, Wang Zhixin and other old marines all vomited. It was even worse, first he vomited out the food he ate, then he vomited yellow water, and finally he even started to vomit blood!

They just came back today, just in time for an urgent mission. It would be a bit unreasonable not to take them with them at this time, but unfortunately there are some things that cannot be softened.

Han Yu took a deep breath and said helplessly, "Platoon Leader Zhang, I can understand your feelings, but the first thing I have to think about now is how to complete the tasks assigned by my superiors.

Considering that the next voyage will be relatively long and the endurance of the two boats is limited, bringing you along will directly affect whether you can successfully complete the tasks assigned by your superiors. "

"There are only twelve of us here, and we can't fit in one boat, so we can divide them into 823!"

"The battery life I'm talking about doesn't mean that the boat can't be crowded, but that once you get on the boat, you will have [-] more mouths. Our fresh water tank is so big, we have to calculate various consumptions."

"We...we can save water."

"Comrade Zhang Xiaojun, stop talking, this is an order, there is no bargaining!"

Han Yu looked at the disappointment of the boys, thought about it and explained: "Even if you don't board the boat, we still need to save water, and we won't even be able to eat hot meals for the next month.

The tonnage of the anti-smuggling boat is not small on the river, but it is just a small boat on the sea. When a wave hits a pot of water, it will disappear, and it will not be able to cook at all, so we may rely on dry food to satisfy our hunger. "

To sail for a month!

Guo Weitao, Jiang Shengqi and the others came to their senses, wondering at the same time what the mission was.

Han Yu didn't know what they were thinking, so he took out his notebook and looked at it, and then said: "Now arrange the tasks before sailing, I have communicated with the shipyard, they will bring people over to install it before twelve o'clock noon" Roland C'. Lao Jiang, Lao Liu, you should be familiar with Roland C, please help him install and debug later."

"Roland C" is an electronic navigation system. In the past two decades, the navy and fishing boats have relied on "Roland C" for navigation, but "Roland C" is outdated, and Western countries have already eliminated it.

Jiang Shengqi felt incredible and couldn't help saying: "Secretary Han, our boat is equipped with the most advanced Guantong navigation equipment, including two color navigation radars, electronic charts, GPS global positioning system, and radio direction finder... "

"I know."

Han Yu put down his laptop and said solemnly: "If we are carrying out anti-smuggling missions, these electronic devices, especially GPS navigation, can be of great help to us, but what we are going to carry out next is not anti-smuggling missions. GPS is very advanced, but the GPS satellite positioning system is American. , we cannot rely on the US satellite positioning system."

The next thing to do is not an anti-smuggling mission...

Everyone was stunned, and couldn't help but think of the increasingly tense situation in the Taiwan Strait during this period of time.

Han Yu looked around at the crowd and gave an example: "On July 93, 7, the Chinese freighter 'Yinhe' suddenly stopped and drifted while sailing in the Indian Ocean. , unable to continue sailing.

At first I thought it was a malfunction of the signal equipment, but no matter how repaired it was, it didn't help.Later, I found out that it was the United States who suspected that China was sending weapons to Iran, and deliberately stopped the navigation signal in the sea area where the "Yinhe" was located.

The lessons learned from the past are there, and we have to learn from them.Not only can't rely on GPS navigation, but also can't rely on the upcoming 'Roland C'.In conclusion, it is very dangerous to rely too much on a single form of ship positioning, because we have to take into account the possible electronic interference. "

Han Yu paused, and then said: "So please take the time to study the charts and think about what you have learned in the military academy and training some time ago. The magnetic compass and sextant have not withdrawn from the stage of history. We It is necessary to master the skills of not drifting or even getting lost in the environment of endless signal interference!"

The sextant is an essential instrument for navigation. It is simple, reliable, well concealed, low in price, and not limited by the coverage area. It still occupies a place in the navigation industry until today.

Naval academies and local maritime academies both regard sextant as one of the compulsory subjects, and proficiency in using sextant to determine azimuth can be said to be one of the skills that professional sailors and merchant marine officers must master.

Jiang Shengqi realized what task he was going to perform next, and was secretly startled, Han Yu said again: "Gong Jian, Wang Xiaolong, your task is to seize the time to purchase all kinds of supplies needed for the voyage, you must act quickly, and you must arrive at 5 p.m. Finish by [-]:[-]."

"Secretary Han, how many days are you preparing for?"

"Don't ask me how many days I will prepare. I only have one request. The oil and water tanks must be filled, the refrigerator and freezer must be filled, and dry food that is not easy to spoil should be prepared. Bottled water should also be prepared. As long as the boat can hold Next, you can count as much as you can hold."

"Yes!"

"Wang Zhixin, Jiang Guochang, you are in charge of guns and ammunition. Prepare five bases of shells for machine guns, ten automatic rifles and two thousand rounds of bullets for each of the two anti-smuggling boats."

Wang Zhixin was taken aback. He stared at Han Yu and asked, "Secretary Han, we are also gunners, but standing here, how do we prepare?"

"When Li Guan comes back, you take a few people with Li Guan to the Qi Island Smuggling and Criminal Investigation Bureau to carry shells. As for rifles and rifle ammunition, Lao Jiang, you can go to the Navy Qi Island base with me to borrow them later."

"Can I borrow it?"

"Should be able to, definitely can!"

……

PS: Headache, fever, very uncomfortable.

Antibody test, seems to be positive again.
