This research focused on three defense industry companies, namely PT Dirgantara Indonesia, PT PAL Indonesia (Persero) and PT Pindad (Persero). This study used a quantitative research approach with a time period from 2011 to 2020. The results of the study show that the magnitude of the effect of efficiency and asset growth on financial performance in the defense industry sector is 45.0% and the remaining 55.0% is explained by other variables not examined in this study. Efficiency and Asset Growth have a simultaneous effect on Financial Performance in the Defense Industry Sector.
