European Defence Planning: Concorde, Franco-British Politico-Military Relations and the Cold War, 1956–68

Cold War tensions between the superpowers marked the years 1956 to 1966, where the United States, Britain and France prioritised European defence against Soviet aggression. Despite being envisaged for civil aviation purposes, the Concorde aircraft was the Franco-British alternative to US proposals concerning the introduction of a supersonic bomber within the Inter-Allied Nuclear Force (IANF) to protect against Soviet attack during the Cold War technological race. This offers a unique case study for the examination of Franco-British bi-lateral partnership in the context of European defence. This article will concentrate on three main themes. The first investigates how Concorde was considered as a viable component for the IANF. Subsequently, the loci of US, British and French policy decisions will be explored with regards to constructing supersonic aircrafts. Lastly, the article considers how foreign policies influenced the shift from a military-use Concorde to a more commercial option. The historiography on Concorde focuses on its commercial impact, and how it affected the Franco-British partnership. Considering Concorde from the defence perspective allows us to analyse the divisions between the US and French grand design ideas – the IANF and Europe puissance – and how they provoked further friction in the Franco-British military relationship.
