Space Weapons and U.S. Strategy [PDF ebook] 
Origins and Development

This book, first published in 1985, analyses the factors that have shaped the militarization of space. By examining in great detail the determinants of U.S. policy, it explains why for over 25 years space did not become the scene of an arms race, and why this began to change in the late 1970s. Both superpowers did, however, develop a limited anti-satellite capability in the 1960s, and these programmes are also discussed.
