This study aims to investigate the impact of defense expenditures on economic growth for the period 1992-2022, in the sample of 10 countries with the highest defense expenditures (USA, China, Russia, India, Saudi Arabia, United Kingdom, Germany, France, Japan and South Korea). The AMG (Augmented Mean Group Estimator) test approach is preferred İn the panel data research process of the study. The findings of the study show that defense expenditure positively affects economic growth in certain country samples. The effect of the control variables of the research model, population growth rate and inflation, on economic growth varies across country samples. The results of this study, which are supported by the literature, show that defense expenditures may contribute to economic growth and development process if they are directed towards domestic production and integrated with modern technology.
