Abstract : The effective drag functions derived by the Naval Weapons Laboratory for the computation of gun ballistic data in digital gunfire control systems are presented. The accuracy and derivation of the functions are given as well as the least-squares coefficients computed for 3- and 5-inch projectiles. FORTRAN listings of the three programs used in the computation of the coefficients are given in the appendices. (Author)
