The tutorial on how to draw a submarine is as follows:

Method 1:

First, we draw the overall outline of the submarine.

Then we draw the windows of the submarine.

Next, we draw the spiral of the submarine.

Finally, draw the door of the submarine. A submarine is ready.

Method 2:

01. First draw the periscope on the submarine, as shown in the picture:

02. Draw the submarine on the basis of the periscope The hull structure of the submarine, and then put the wing on one side of the submarine on the hull, as shown in the figure:

03. Then draw the above structural graphics and pilot on the hull of the submarine. room, as shown in the picture:

04. Finally, draw the tail structure of the submarine behind the submarine, so that the submarine is finished, as shown in the picture:

< p>The above are two common ways to draw submarines!

Knowledge expansion:

Submarine (also known as: Blackfish, Submarine), also known as submarine ship or submarine, is a ship that can operate underwater. There are many types of submarines with different shapes, ranging from small civilian diving detectors that are fully automatic or operated by one or two people and operate for several hours, to Russian Typhoon-class nuclear submarines that can carry hundreds of people and can stay submerged for 3-6 months. . According to volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices.

Large submarines are mostly cylindrical, with a vertical structure (bridge) usually set up in the middle of the ship. In the early days, it was called the "control tower/command station", which contained communications, sensors, periscopes and control equipment. Today's deep-sea submarines or professional submarines often no longer have this design.

Since World War I, submarines have been widely used and have occupied important positions in the navies of many major powers. Their functions include attacking enemy warships or submarines, coastal protection, breaking through blockades, reconnaissance, and covering up special forces operations. wait. Submarines are also used for non-military purposes, such as marine scientific research, property rescue, exploration and mining, scientific detection, maintenance equipment, search and rescue, submarine cable repair, underwater tourism, academic surveys, etc. The super rich even use them for underwater Mobile mansion.

Submarines are recognized as strategic weapons (especially in disarmament or arms expansion negotiations). Their research and development requires high and comprehensive industrial capabilities, and only a few countries can design and produce them themselves. In particular, ballistic missile nuclear submarines are a key pole of the nuclear triad. Submarines are also an earlier stealth vehicle. If the noise of a submarine drops to about 90 decibels, it can be "submerged" in the vast ocean background noise, and it cannot be detected by modern sonar.
