A projectile according to an embodiment of the present invention includes a first stage, a second stage, and a cowl mounted on the first stage and the second stage, wherein the cowl includes a first-stage cowl fixed to the first stage, and a second-stage cowl detachably connected to the first stage and fixed to the second stage. The projectile includes a solid motor mounted on the second-stage cowl. When the solid motor is ignited, the first stage, where the first-stage cowl is fixed, and the second stage, where the second-stage cowl is fixed, are separated from each other by the pressure of the ignition gas. Thus, the present invention can provide the projectile that can increase the reliability of stage separation by implementing a simple fastening structure between the first and second stages.
