With the onset of the Cold War and a new nuclear world order, Soviet physicists found themselves at the nexus of scientific research and weapons development. This article investigates the subjectivity of these physicists as an issue of masculinity. Influenced by Connell's models of subordinated, complicit, and hegemonic masculinity, the article finds that the stories nuclear physicists tell about their research in the 1950s are inconsistent and shifting, with the narrators simultaneously remembering unfreedom and privilege. They tell of being conscripted to military work against their will but then enjoying (and deserving) the resulting power, all while maintaining strong homosocial networks in the laboratory predicated on excluding women. Evidence from personal narratives provides unique insight into these multiple masculinities and the way the authors position themselves as (masculinized) Cold War subjects.
