Why are there so many national flags on China's naval vessels? What does it stand for?

There are strict rules on the time and order of hanging flags. Generally, the timing of hanging the national flag is to welcome the important yuan of the government, major festivals, the visit of foreign warships, before the visiting formation leaves the dock, when it arrives at the port of the visited country, when it berths abroad, and so on. The full flag is hung between two mast transverse trusses and connected to the flagpoles at the bow and stern of the ship respectively. Two mastheads are hung with a national flag, and a navy flag is hung on the flagpoles at the bow and stern. The destroyer is full of flags, usually the No.2 flag, about 67 sides. It depends on the actual length of the ship and the distance between the fore and aft masts. The single-masted ship is connected with the flagpole at the bow and stern through the mast transverse truss, and the national flag is hung at the top of the mast. There are five specifications for signal signs. Divided into 1, 2, 3, 4, 5. 1 max, 5 min. A set of signal signs has 46 faces. Among them, there are 26 letter flags, 26 digital flags 10, 4 directional flags, 3 substitute flags, 26 executive flags 1, 26 commitment flags 1 and 26 international commitment flags 1. The number flag is a triangular flag, the letter flag includes a square flag and a dovetail flag, and the commitment flag and the international commitment flag are trapezoidal flags. The arrangement of the whole flag is two sides and one tip. Square flag refers to rectangular flag, pointed flag refers to triangular flag, dovetail flag can be used as square flag, trapezoidal flag is also called long flag, and can be used as pointed flag. In order to hang the flag conveniently, there are three thin steel wires from the top of the flagpole at the bow to the top of the main mast, from the top of the main mast to the top of the back mast, and from the top of the back mast to the top of the flagpole at the stern. When our ship formation arrived in the visiting country and the first cable was tied to the cable post, the signalman quickly raised the flag along the thin steel wire with electric pulley. There are some special requirements for flying the whole flag: there cannot be a communication flag with the same pattern as the national flags of various countries, nor can there be a single flag used to indicate combat, anti-nuclear and anti-air strikes. One side of the national flag means nothing. When the visiting ships of our country arrive in the visited country, the naval ships of the visited country usually hang full flags to welcome them. The order of arrangement is the same as ours, but the difference is that the full flags of foreign troops are one or two less than ours.

Second, the generation of Manchu flag.

30 minutes before the visiting formation leaves the dock, in order to leave the dock conveniently, it is generally necessary to lower the whole flag, hang the whole flag instead, and then lower it after leaving the port. Daiman Banner is to hang the national flag 1 on two masts and the navy flag on the front and rear masts. It is stipulated that when the flag is full, if it rains or windy, it is not necessary to hang the flag full. When the formation leaves the dock, the square yellow "Q" flag is hung at half, indicating that the formation leaves the dock as one. The "Q" flag is hung on the masthead, indicating that the formation has started to leave the dock, and the "Q" flag is lowered, indicating that it has left the dock. The sign of leaving the dock is to untie the last cable.

Welcome, farewell flag

When sending our fleet on a visit, the main mast of the visiting ship was hung with flag groups to greet the chief: one group was "LBF" and "LBV", and the "L" flag was a square flag consisting of yellow, black, black and yellow squares, with yellow squares in the upper left corner and lower right corner, and black squares in the upper right corner and lower left corner. The "B" flag is a red dovetail flag. The "F" flag is a red diamond in the white flag, and the four corners of the diamond are in the middle of the four sides of the flag. The V-shaped flag is a thick red cross in the white square flag, and the four endpoints of the cross extend to the four corners of the flag. When the ship visited Southeast Asia for the first time, before leaving Shanghai, it hoisted two sets of national flags, namely "LBN" and "LBZ", to the head of the navy, the officers and men of the army and the diplomatic envoys of the visiting countries in China. The "N" flag is a square flag with four horizontal rows. The first row is blue, white, blue and white squares, the second row is white, blue, white and blue squares, the third row is the same as the first row, and the fourth row is the same as the second row. The "Z" flag is a square flag surface composed of four isosceles triangles, with yellow above, red below, black on the left and blue on the right, and the tops of the four isosceles triangles are in the center of the flag surface. Thank you for your concern and encouragement, and ensure the completion of the task. "Thank you, goodbye!"

Navigation semaphore

When the ship untied the last cable, it raised the sailing flag, that is, the navy flag, on the mast yard. Sailing day and night, hanging all the time. This is to show people which country this warship belongs to. Experienced sailors can't tell which country they belong to when they meet foreign warships in the ocean. Just look at the sailing flags with a telescope and you will know which country they belong to. Merchant ships generally salute warships. When a merchant ship salutes a warship, the signalman on the warship should lower the navy flag to one third of the top of the flagpole in return, and then raise the navy flag to the top to mark the end of the ceremony. When warships meet, they only whistle to pay tribute and return gifts, without using semaphores.

Third, the semaphore of sea replenishment.

After a period of sailing, visiting ships need to be replenished with oil and water, which are divided into horizontal and vertical. No matter which replenishment method, a signal flag should be hung to indicate various orders and replenishment actions in the replenishment process. Both the receiving ship and the supply ship should hang the flag group: "VP", and the "P" flag is a small white rectangle in the middle of the blue square flag, and its length and width account for one third of the top, bottom, left and right respectively. At the same time, the other mast is hung with spherical, diamond and spherical signals, indicating that the ship's maneuvering is limited. Explain to the passing ships: "Our ship is carrying out replenishment operations, please pay attention to safety."

Reverse and turn semaphore

When the ship needs to reverse when leaving the dock or sailing in the channel, the "S" flag should be raised to the top for safety reasons. The "S" flag is a small blue rectangle in the middle of a white square flag. It means telling passing ships: "I have backed up, please pay attention to safety!" " "When the ship turns left, hang the" I "flag. The "I" flag is a black circle in the middle of the square yellow flag, which means: "I turn left. The "I" flag is raised to the middle as "I want to turn left", raised to the top as "I want to turn left" and lowered as "I want to turn left! "When the ship turns right, hang the" E "flag. The "E" flag is a square flag, with blue on the top and red on the bottom, each half. It means "I turned right". When the ship is maneuvering, in addition to using the semaphore, according to the international collision avoidance rules, it is also necessary to use the whistle to cooperate: one right, two left and three inverted. That is, when the "S" flag is raised, whistle three times. When "I" is hung up, blow two short whistles. When the "E" flag is raised, give a short whistle. The steps of raising and lowering the flag are basically the same as turning left.

Cross the territorial sea line and equatorial semaphore

When visiting ships cross the territorial sea line and equator, in order to arouse the enthusiasm of visiting officers and soldiers, an oath ceremony is generally organized and a flag for navigation is hung at the same time. On behalf of full-flag sailing, the national flag is hung on two masts, and the navy flag is not hung on the flagpoles at the bow and stern. 1 12,13, 167, 82 and 953 have all organized similar activities. When organizing these activities, the flying five-star red flag, neat sailors' phalanx, clenched fists, loud vows and snow-white waves constitute a unique sea scenery.

Fourth, the flag language

Flags are also a way of communication at sea. Suitable for daytime, close range and good sight distance. When the distance is close at night, optical communication is generally used. The hand flag is a small square flag with a wooden stick at the root. Hand flag communication requires the use of two flags. The signalman held the flag in both hands and stood in a higher and more conspicuous position on the ship's side. Different letters and symbols are expressed by the different positions of the flag relative to the body. For example, the left hand is raised vertically, and the right hand is extended in parallel to indicate "P". The right hand is raised vertically and the left hand is extended in parallel, indicating "J". Hands sticking out in parallel means "R". Raise your hands vertically to indicate sound insulation. Several pinyin letters make up a word, and several words make up a meaning. The hand flag can also point out the direction for the ship (ship) to put down.

Flags before and after leaving foreign docks

Before my visiting warship formation enters the territorial sea line of the visited country, the visited country usually sends warships to meet it. When entering the territorial sea line, according to the agreement between the two parties, the national flag of the visiting country will be hoisted. The national flag of the visited country is hung on the starboard side of our main mast, and our national flag is hung on the port side of the main mast. When docking, the "H" flag rises to the top, indicating "start docking". When the first cable was brought, the "H" sign was lowered. The H-shaped flag is a square flag, half white and half red. It means: "I have stopped." When you bring the first cable, you start hanging flags and navy flags at the bow and stern. If the warship of the visiting country hangs the welcome flag, I will hang the thank-you flag group to express my gratitude. Leaving the dock is the same as leaving the dock in our country. During a foreign visit, generally speaking, a grand flag-raising ceremony will be arranged every day. Raise the national flags of both sides at the same time.

Attachment 1: Various flags in semaphore.

Maritime semaphores used to be used for communication between ships, and the general usage was to spell short sentences. In addition, a single flag also has special significance. Nowadays, sea semaphores are generally only used for decorative purposes.
