A study was conducted to determine the appropriate training objectives for fire control personnel aboard nuclear submarines, to identify specific requirements for training materials to accomplish these objectives, and to provide functional descriptions of recommended training devices. A task analysis was conducted to determine the skill and knowledge requirements for each member of a fire control party. A set of training objectives was drawn up based on these requirements and on trainee input and output characteristics. Existing training facilities were assessed in the light of the proposed training objectives. On the basis of this assessment it was suggested that existing training devices should include more degraded data and simulated system malfunctions in order to more accurately mirror real-life situations. In addition, a periscope visual-task trainer and a generalized individual trainer were proposed to fill training needs not met by existing devices. (Author/JY)
