Examining open access civilian and military space policy, strategy, and doctrine documents, this book highlights emerging trends and developments in military space strategy. Bert Chapman collects public documents from Australia, Canada, the European Union, NATO, the United States, and the United Kingdom from 2017 onward to illustrate space’s critical importance to national and international security and to multiple areas of civilian economic and personal use including climate change, food security, personal and global communications, and the potential for expanded space exploration.In light of recent revelations that Russia may be capable and desirous of exploding nuclear weapons in space to damage civilian and military space-based infrastructures of the U.S. and other countries and China’s increasing space assertiveness and capabilities, it is more important than ever that civilian readers have the access and background knowledge necessary to parse publicly available documents relating to space strategy so that they may effectively participate in the legislative and regulatory policymaking processes of their governments.
