A projectile includes a mechanism which allows the fin position to be reversed 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 deplo...


A kinetic energy projectile comprising: a penetrator within a sabot; a plurality of pivoting fins attached to said penetrator, said fins each having a first leading edge and a second leading edge; means for restraining said fins such that only said first leading edge of said fins is exposed during launch of said projectile from a gun tube; means to provide rotation to each said pivoting fins after said projectile exits from said gun tube, said means to provide rotation to each said pivoting fins comprising an aerodynamic lifting surface on each said fin;...
