What does the colorful flag on our warship mean?

Navy bunting, namely "international signal communication flag", is commonly known as "ten thousand national flag".

It is an international signal flag, which is specially used for communication between ships or between ships and the coast. * * There are 4 kinds of 40 faces, including 26 letter flags (rectangular or dovetail), 10 number flags (trapezoid), 3 substitute flags (triangle) and 1 answer flags (trapezoid). The colors and styles of international signal flags are different. When in use, according to the provisions of international signal coding, a flag can be used alone or in groups of several flags. A group can be composed of several letter signs or several number signs or several letter signs and several number signs. A flag can be hung on a flag rope or one or more sets of international signal flags, which is called "one hanging". According to the size, signal flags can be divided into five types: 1 flag, No.2 flag, No.2 flag, No.3 flag and No.4 flag. Warships are equipped with signal flags of different sizes according to their sizes. Signal flag communication has been adopted by navies of various countries for a long time because of its intuitive and simple advantages. The navy uses the international signal flag not only to convey information, but also for grand etiquette.

Main forms:

First of all, hang all the flags.

There are strict rules on the time and order of hanging flags. Generally, the time when the national flag is hung is to greet the party and state leaders, the government and the army, foreign heads of state, major festivals, visits by foreign warships, before the visiting formation leaves the dock, when it arrives at the port of the visited country, when it is parked 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.

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.

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.

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.

5. Before and after departure from foreign docks:

Before the visiting warship formation enters the territorial sea line of the visited country, the visited country will generally send 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 the main mast of the visited country, and the national flag of the visited country 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 a welcome flag, the visiting country should hang a thank-you flag group to express its gratitude. When leaving the dock, it is the same as when the visiting country leaves the dock. 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.

Hanging time:

There are strict rules on the time and order of hanging the flag. Generally, the time when the national flag is hung is to greet the party and state leaders, the government and the army, foreign heads of state, major festivals, visits by foreign warships, before the visiting formation leaves the dock, when it arrives at the port of the visited country, when it is parked 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 full flags 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.
