“Anyone wanting to understand current US military space policy must appreciate the logic pursued by successive US presidents in the two decades following the end of the Second World War. Sean Kalic has done an admirable job in piecing together the history of early US involvement in the militarization of space. This book serves as a useful addition to our understanding of this critical period.” | “Kalic has written a book that analyzes US military space development, policy, and presidential involvement, which has not previously been done. The level of detail will benefit both military space experts and students of military space. He identifies a common theme among US presidents during this period: the use of space for photoreconnaissance, early warning, intelligence gathering, communications, navigation, and weather data collection. Indeed it is worth noting that subsequent presidents until Reagan followed this path. The importance of recognizing the use of space for these military purposes cannot be overstated.” -- Matthew Mowthorpe, Ministry of Defense, United Kingdom
