Why Buy American? The International Politics of Fighter Jet Transfers

When it comes to buying military aircraft, what leads states to prefer one supplier over the other? This paper explores this question from the perspective of international relations theory. First we use social network analysis to map out fighter jet transfers during and after the Cold War and examine the extent to which historical structures of international hierarchy shape contemporary supplier-receiver relationships. Next, we use a basic probit model to analyse the origins of fighter jets in the world's air forces today to evaluate the effect of interstate orders of super-ordination and sub-ordination on sourcing patterns. All things being equal, the more a state is embedded in US security and economic hierarchy, the more it is likely to buy American-made fighter jets.
