The general objective of this contract is to utilize the hot cup-cold deep draw fabrication method to develop improved monolithic rocket motor cases for 40 and over diameter solid propellant rockets. The specifice goals are 1. The development of reliable motor cases with hoop stress limits substantially in excess of 200, 000 PSI steel equivalent. 2. A capability of fabrication with reasonable ease on an industrial scale. 3. A producibility proven by reliability tests at final full scale. 4. The objective is to be accomplished utilizing the Pershing 2nd stage motor case configuration.
