The fundamental goal of the nuclear trained submarine officer is to develop the professional skills and operational background to command a nuclear submarine. The achievement of this goal is accomplished through a well-defined series of professional qualifications, advanced training and operational sea experience. Completion of Nuclear Power School and Nuclear Prototype Training will be the first challenge facing a Nuclear Submarine Officer after commissioning. Upon completion of Nuclear Power School and Nuclear Prototype training, the officer is assigned to a submarine. Prior to reporting to the first submarine, the officer attends a 13 week Submarine Officer Basic Course in Groton, CT. This period of instruction provides an opportunity to learn the theory and principles of submarine operation and control, the basic administrative responsibilities of a division officer, the theory of the submerged fire control problem and weapons systems, and the fundamentals of submarine operations and tactics.
