Given Peenemünde's ambivalent military and technological history, from rocket development during the Nazi period to East German naval and air bases during the Cold War, its musealization was considered both a chance and challenge during the region's deindustrialization in the 1990s. Local residents’ support of veteran engineers promoting an apologetic view of Nazi rocketry was met with bewilderment. However, a space park project and anniversary event were spearheaded by government and industry representatives, turning a regional affair into an international controversy. The article analyzes the function of memory work and the remembrance of technological progress in rural northeastern Germany before and after German reunification. Based on archival sources and interviews with former officers and museum advocates, it traces the Peenemünde museum project through a history of ideological and biographical caesurae, enthusiasm, political promises, and socioeconomic despair.
