Fritz K Feldmann, Craig Christenson, Paul J Griffith: Reduction of velocity decay of fin stabilized subcaliber projectiles. Pacific Armatechnica Corporation, Patrick J Walsh, May 9, 1995: US05413049 (4 worldwide citation)

The terminal effectiveness of fin stabilized, subcaliber armor piercing projectiles depends primarily on the impact velocity at the target. The aerodynamic drag and related velocity decay experienced over the trajectory from the gun to target is reduced by shortening the length of the acceleration t ...
