This report describes the current status of the project Performance assessment. This two-year project was started in 2006 with the purpose to develop the capability to assess the performance potential of new/modified energetic material, warhead concepts, launching and propulsion techniques when these are used in weapons and weapon systems. In this project performance refers to quantitative properties that are of tactical importance, for instance weight and range. The project is restricted to handle the influence that launching, propulsion and warhead technology have on weapon performance. The purpose of this report is to summarize the work done so far and to serve as a direction for next year. The report also aims to make the project´s focus and restrictions with regard to related areas concrete.
