Abstract: A protection covering for folded tail fins of a projectile. The protection covering is installed to surround outer portion of the folded tail fins of the projectile and protects the tail fins against external high pressure, whereby the tail fins are not damaged even at high pressure generated in a launching process of the projectile. After the launch of the projectile, the protection covering is separated from the projectile by the pressure applied on the inner side surface of the circular plate portion of the protection covering by the accumulated combustion gas inside the air pocket. The protection covering is automatically separated from the projectile without providing any other mechanical structure immediately after the launch of the projectile, thereby providing an effect to allow the tail fins to be deployed quickly and economically.
