The RT-21 was the first mobile ICBM developed by the Soviet Union. Its innovative concept and design were created by Alexander Nadiradze. The RT-21M Pioneer (SS-20 Saber) and succeeding missile complexes relied on the SS-16 base concept and were used by Nadiradze for many of his later projects. The program became mired in a series of treaty complications, including questions regarding its use of theatre missile launchers. It is unlikely that the RT-21 ultimately reached deployment, and by the mid-1980s, the program had been scrapped. Its maximum period of storage on a launcher was 5 years, and preparation time for launch was 40 minutes.[1]
