This paper examines tactical and ethical considerations for the implementation of drones in the Swedish naval forces. Research concerning ethics and the use of drones differ between being an accepted technology in warfare and an unfair advantage for the user. Research of tactical aspects in using drones show clear advantages for naval tactics. While several nations worldwide have adopted drones in their navy Sweden has not. By examining what considerations can be made concerning ethics and tactics, the implementation of drones can be made easier.  By applying an ethical perspective aspect for drones and one theory concerning the tactical aspect for naval warfare and applying these to different drones, this study examines whether drones can fulfill naval duties simultaneously as well as being ethical in their usage.  The analysis shows that unarmed drones can with ease solve the majority of tactical tasks ethically. Drones which are produced with weapon capability can theoretically complete all tactical assignments however, cannot be considered as being ethical. The findings show that armed drones are not considered ethical; un- armed drones can be exploited in the Swedish naval forces while being ethical and that ethical theory con- cerning drones in the armed forces needs developing in both war and peacetime
