Purpose: This research aims to contribute to History of Education Studies as well as to New Cold War Studies, by examining a Reactor Technology Specialist Engineer program, launched in Hungary three times in the 1980s for Cuban nuclear engineers, graduates of the University of Havana. Design/methodology/approach: The institutional setting, the content of the program, the teaching staff, the students, and the outcomes are studied. The factors that motivated the birth of this special program are examined, including the following areas; (1) in what ways it was different from the courses in which foreign students participated in Hungary; (2) what its strengths and weaknesses were; (3) how we can learn from this past experience and what relevance it has for the present. Findings: The analysis - carried out within the context of Cuban-Hungarian relations in the Cold War - demonstrates that these two satellite countries used the fields of science and education to widen their international possibilities and at the same time to reinforce their national interests by cooperating with each other. Originality/value: The investigation is based on archival sources, university yearbooks and journals as well as contemporary Hungarian press. Written sources were complemented by interviews with Cuban students and Hungarian teaching staff, thus providing a personal perspective, balancing official views.
