Free flight spark range tests of the Copperhead projectile were conducted in the BRL Transonic Range, to obtain free flight aerodynamic data for the full-scale, tactical configuration. The free flight data show good general agreement with previously obtained wind tunnel results. The tactical Copperhead projectile is statically stable at all Mach numbers tested. A weak slow-arm dynamic instability was observed at transonic and high subsonic speeds, for small angles of attack. The mild dynamic instability could result in limit-cycle, or 'coning' motion at transonic speeds; however, the data obtained in the present tests are too sparse to permit a quantitative determination of limit-cycle behavior.
