This chapter moves beyond the dominant narrative of industrialization that is a hallmark of South African development and modernization during the Second World War. It considers instead the ways in which this narrative was presented to a divided South African public in order increase support for the War. South African military strength and its associations with science, technology and the modern were conveyed to the public through the Rand Show in 1940, the nation-wide recruitment drives such as the Steel and Air Commandos, the War Train and the Liberty Cavalcades held in Johannesburg and Cape Town respectively. The chapter concludes with the opening of the South African National War Museum in 1947. Throughout, it is evident that the display of military technology was associated with patriotism and nation-building, serving as an exercise in propaganda. It incorporated South Africans into the war effort and brought them into proximity with state and military power. Yet this demonstration of power also served to caution those elements in society who opposed and actively hampered that same war effort. Technology here, was both an instrument of inclusion and of domination.
