Abstract: A device is disclosed for deflating a gas cavity about a projectile formed upon entry of the projectile into a liquid. The device can include a wall coupleable with a body operable as a projectile and defining an exterior and an interior space. The wall can be oriented toward a trailing end relative to a leading end defined by the body. The device can also include at least one inlet to facilitate gas flow from the exterior to the interior space. An outlet can facilitate gas flow from the interior space to the exterior and can be oriented toward the trailing end relative to the at least one inlet. Upon entry of the body and the wall into a liquid and formation of a gas cavity about a portion of the body and the wall, the at least one inlet can be located within the gas cavity and the outlet can be located outside the gas cavity, such that gas flows from the exterior through the at least one inlet to the interior space, and from the interior space through the outlet to the exterior to deflate the gas cavity.
