Abstract	The presentation traces the development of large solid rocket motors and the thrust vector control (TVC) systems they used. An overview of TVC types is presented as is a detailed schematic of the Shuttle SRB nozzle which uses the most common solid rocket TVC nozzle design – the flexseal. The presentation uses historical photographs to highlight the programs and their place in the chronology of large motor development as well as the development of our defense and space exploration capabilities. It highlights some system tests that never became operational but demonstrated capabilities that could be used if the mission requirements demanded. The presentation ends with the current motor development activity for the new NASA launch vehicles – the Ares I and the Ares.
