The invention discloses a bubble drag reduction system and a ship comprising the same, and belongs to the technical field of ship gas lubrication drag reduction. The device comprises a bottom plate, a top wall, a side wall, a rear wall, a ventilation plate and a cover plate, the bottom plate is fixed on a ship outer plate and is in the same shape with the ship outer surface, and the side wall is fixed on the bottom plate; a top wall is fixed to the top of the side wall, a ventilation plate is detachably fixed to the middle of the side wall, and a cover plate is detachably fixed to the bottom. A supporting wall is arranged between the ventilation plate and the top wall, the supporting wall, the ventilation plate, the top wall and the side wall jointly form a pressure stabilizing cavity, and an air inlet is formed in the position, at the pressure stabilizing cavity, of the top wall. The ventilation plate, the side wall and the cover plate jointly form an exhaust cavity with an opening in one side, and the exhaust cavity communicates with the pressure stabilizing cavity; the top of the opening of the exhaust cavity is provided with a rear wall extending obliquely downwards and backwards, and a gap is formed between the rear wall and the cover plate and forms an air outlet. A low-speed and uniform mesoscale bubble layer can be generated in the whole length direction of the ship bottom, and the effect of stable resistance reduction is achieved.
