A projectile includes a mechanism which allows the fin position to be reved after the projectile leaves the launch tube thus allowing the fins to have reversed leading edges, which avoids the costly weight of the one-piece design in the prior art, which is a parasitic weight that will result in a lower velocity, and consequently lower kinetic energy, from the same propellant charge. This mechanism also avoids having extra pieces falling from the muzzle and near the firing team or troops near the gun, and has the advantage of a simple, low-weight deployme...
[ What is claimed is:] [1.] A device to protect the fins of a projectile comprising:a moveable shield on the leading edge of said fin;means to restrain movement of said shield;means to eject said shield after said projectile exits from a gun tube after launch; and,further comprising padding material between said shield and said fin.
