An incremental approach to the complete disarmament of outer space could continue with the prohibition of any type of military activity on board earth orbiting manned space stations. The U.S. and the USSR are committed to placing such stations in permanent orbit within the next decade. An international agreement giving demilitarized status to them would be a major achievement.

Article IV of the Outer Space Treaty prohibits the establishment of military bases, installations, and fortifications on the moon and other celestial bodies. Manned space stations in earth orbit should be subject to the same limitations, with military personnel permitted for scientific research only.
