The Swedish armed forces will be transformed to NBF (the Swedish implementation of the network centric warfare). This implies that units and systems will be designed so that services and information can be exchanged. Therefore, a common architecture is needed, here denoted FMA (the architecture of the Swedish armed forces). FMA should in short time make possible development of systems, such as technical, organizational and composite systems. Requirements on NBF, from which requirements on FMA can be derived, are called architecture driving requirements. Requirements directly on FMA are called architecture requirements. The objective is to perform a first analysis of the architecture driving requirements. To put those requirements in a context, their connection to the statements about NBF and how they can be related to architecture requirements are presented. The study was performed in five steps; documentation study, identification of architecture driving requirements, the structuring of those, and identification of relationships. The document study was based on Preliminär målsättning för systemdemonstratorerna 2005 och 2006 and Preliminär målsättning för Försvarsmaktens ledningssystem 2010. This resulted in the identification of 438 statements. From those statements 33 architecture driving requirements and 45 architecture requirements were identified. These requirements constitute a first set of requirements, which need to be further validated.
