The main task of this paper is to analyze and to discuss the present binding regime of the legal status of double-uses satellite systems. In particular to outline the urgent need to strength the regime of immunity of satellite systems due to the international terrorism threat. This may be obtained by turning of the appropriate bilateral agreements between the Russian Federation and the USA into multilateral Treaties. Such «immunity» would cover all operating space objects, irrespective of their military or civil designation. This approach is justified taking into consideration that military satellites enhanced international peace and security and had broad advantages as a counter-terrorism means.
