A recurrent criticism of most major weapon system acquisition programs has been that training system requirements have been an afterthought. The result has often been catch-up, shotgun approaches to training development, which often do not respond to the total training requirement. Extensive support funding is often expended on the use of actual equipment for training and many key operator and maintenance tasks are never thoroughly trained. As part of a more timely attention to training matters, this paper presents an initial view of the future training requirements for the Advanced Amphibious Assault (AAA) Program. Since the program is in the Concept Exploration Phase, it is clear that the training system requirement will evolve and be further refined. However, the intent of this paper is to start the training requirements definition process early enough to involve both government and industry in the design of efficient and cost-effective solutions to the future AAA training challenge.
