Abstract : This test program was conducted to demonstrate the minimum tip-off tube launcher concept, evaluate the real-time radar registration technique, and evaluate rocket precision for the 6-inch diameter, 218-pound RIP Rocket. The program has been completed with the launch of all eight rockets, and has provided data to indicate successful accomplishment of all objectives. In addition, this flight program has uncovered specific areas for further investigation, and has strengthened the position that free rockets of this size can be satisfactorily launched from a stepped tube with minimum tip-off error. (The 1 sigma tolerance in the computed 71 milliradians/seconds tipoff with a one-sigma variation of 97.2 milliradians/seconds is due to the limited 8-test sample size, and to inaccuracies in the reading of camera tip-off data.) The radar real-time registration program predicted impact (hence, immediate re-aim) to within 60 feet of actual surveyed impact. The paired firings provided a precision of 6.24 mils, a value achieved notwithstanding environmental changes occurring in the 25-minutes between rounds. Since the winds were considerably variable over the 25-minute time frame, the 6.24 mils probably equates to a round-to-round precision under 4 mils.
