Command of the skies: An air power dataset

We introduce a dataset on air power. Air power is the ability to inflict damage on an adversary through the air, and its successful application depends on achieving command of the skies. To achieve command of the skies, countries invest in a variety of types of military hardware and training, especially fighter aircraft. Our dataset contains information on the number, type and technological characteristics—including weaponry, avionics, speed, maneuverability and stealth characteristics—of each country’s fighter and attack aircraft for the period 1973–2013. We also introduce two new air power variables based on this data. The first is Country Air Power, a country-year measure of air power. The second is Expected Air Superiority, a dyad-year measure of which actor is likely to achieve air superiority in a military conflict. We illustrate the utility of this dataset by examining the relationship between air power and militarized dispute initiation, the duration and success of coercive bombing campaigns, and coercive behavior more generally. We find that command of the skies significantly affects conflict and coercive behavior.
