The invention discloses a low-water-resistance submarine. The low-water-resistance submarine comprises a submarine body. The low-water-resistance submarine is characterized in that a drainage channel is formed in the submarine body in the extension direction of the length of the submarine body. According to the low-water-resistance submarine, the drainage channel is formed in the submarine body, the underway submarine forms negative pressure in the drainage channel, partial seawater at the front end of the submarine flows through the outer surfaces of the two sides of the submarine body, the other part of the seawater rapidly passes through the drainage channel in the submarine body and is directly discharged through the tail of the submarine body, the seawater passing through the outer surfaces of the submarine is reduced, the low water resistance of the underway submarine is obviously reduced, and the cruising speed of the submarine is increased.
