1951From August 3rd to September 4th, Zhu De particularly emphasized that the construction of the navy should be strengthened according to the characteristics of the navy. Zhu De said that the navy is different from the army, fighting in the ocean, and artillery warfare plays a particularly important role. There are few or no opportunities for hand-to-hand combat in naval battles, but guns are widely used. With the cover of coastal guns, torpedoes, various guns on warships and the air force, it is possible to defeat the enemy's attack from the sea. Therefore, we must attach importance to naval artillery training. ...

In the past, in order to annihilate the enemy's effective forces, the army did not take the city as its main goal. The navy is different. The task of the navy is to defend the front line of national defense and destroy the enemy at sea. Therefore, coastal artillery should have a solid and permanent artillery base. In addition to regular drills, artillery often has to build more fortifications.
