 Thank you for posting your question on History Hub. 
 
 Definitive information on the nuclear stock pile of the USSR from 1950&ndash;1988 will be in Russian archives. 
 
 The best American estimates will be in Central Intelligence Agency reports. You will find declassified versions of those documents on the CIA's Freedom of Information Act Electronic Reading Room and Center for Study of Intelligence Books and Monographs websites.
