It is important to consider the protection of space assets and the conservation of socio-economic systems through government investment in Japan, taking into account the recent international situation. This paper will categorize national security satellites, and then consider recent technological trends in US communications satellites and reconnaissance satellites, which are leading the way in this field. In addition, it will analyze the status of the US government's budget investment required for such technological development in comparison with Japan, and discuss issues and directions related to future national security satellites.
