The goal of this master thesis, "Analysis of Typhoon-class submarines", is to explain basic principle of operation and design of submarines and, at the same time, to give a more detailed and clearer insight into the Typhoon class submarine. The paper is divided into six chapters. The first chapter briefly describes the occurrence of submarines and their development through history until today. It also describes how occurrence of a submarines impacted on changes in maritime warfare. The second chapter, through historical facts, attempts to describe how submarines were created and which submarines preceded the Typhoon class submarine occurrence. It also explains how was created the Typhoon submarine class. The third chapter describes the general characteristics of the Typhoon class submarine. In the fourth chapter, by strength calculations of solid hulls, is determined whether it is possible to build hulls with structural dimensions stated in the literature while at the same time satisfying the strength criteria for loads acting on a submarine during its navigation in the operating depth. The fifth chapter deals with weapons and outfit of a Typhoon class submarines. The sixth chapter deals with the stability issues. The stability explanation of a Typhoon class submarines is based on the general explanation of submarine stability which is also included in chapter. It also analyzes the stability of Typhoon class submarines for six possible damage scenarios for the underwater and surface sailing conditions. Regarding six analyzed damage conditions analysis shown that the damage of the after peak is most critical. At the end of the master thesis a conclusion is given.
