"is.present research has been done in terms of applied purpose and method with a qualitative and comparative approach. Based on this, the data of study have been collected in the form of a library to analyze the naval operations of the First and Second World Wars and compare the differences and similarities. The results of the research show that the focus of World War I naval operations was on the principle of surprise and the focus of World War II naval operations was on the concentration of forces.
