The United States pring{pal ‘aims may be categorized as follows: 9 34 yet 1. To improve weapons. 2. To measure the effects of weapons. 3. To explore peaceful applications of explosions. In all of these areas some progress can be and is made without nuclear tests through theoretical analysis and laboratory experiments. However, in every ease after such work, full scale nuclear tests are required for confirmation and extension of the information. By careful design of tests, while a partic- ular test may have one primary objective, measurements can be carried out which support all ef the national aims. Thus, vitle a test may be required to study a new weapons design concept, the explosion can be used also to obtain weapons effects data and to contribute to peaceful applications. Let us now discuss more fully each of the national aims and indicate the ~ kinds of testing required to obtain the measurements of interest. The objective of nuclear weapons development in the United States is directed toward satisfying military requirements for bothlimited and general war. To the extent practicable, weapons are developed which are discriminating in effects and which provide flexibility in employment.
