摘要

Some products and capabilities that are critical to national security applications have very limited parallel civil use, or demand added capabilities that go beyond civil usage needs. Consequently, when there are long gaps between U.S. development programs for systems using those products and capabilities, the U.S. production base and expertise associated with these products and capabilities erodes or disappears. A military and civil-space trend in recent years has been to have far fewer major system development programs, lower production bases for the products resulting from those programs, and much longer gaps between the start of such programs. Consequently, access to an increasing number of products and capabilities critical to national security are at risk. Example areas of concern include means to develop high thrust hydrocarbon-fuel rocket engines (with recent reliance on Russian engine technology) and continued advancement of radiation hardened processors. When these domestic production bases and associated technical capabilities disappear, the result is either high costs and delays associated with reestablishing the capabilities when needed again, or reliance on foreign suppliers that may have conflicting national interests.
