Understanding the impact of air power

With a lower risk of casualties and a high degree of precision, air power is an attractive foreign policy tool to powerful states that have increasingly relied upon it in recent years. This paper presents newly collected data on uses and effectiveness of air power in interstate wars from 1914 to 2003. The dataset provides more complete and comparable cases that can be useful in answering questions of not only the coercive effectiveness of air power, but also of the decision to use air power in conflict, of ethical concerns arising from the use of air power, and of the interaction of air power with other military and foreign policy tools. In addition to introducing the dataset and discussing trends in the data, a preliminary empirical application is provided, re-examining the relationship between strategy and air power effectiveness.
