Spacepower for a New Millennium examines how military space activities might best contribute to United States national security by analyzing key current and future issues such as missile defense and how to organize for military space. Composed of essays written by eminent participants in the realms of space, politics, academia, and national security, this book focuses on the issues raised in U.S. Space Command's 1998 report, Long Range Plan: Implementing USSPACECOM Vision for 2020. The book is divided into four parts: current military space issues, space and military defense, organizing for military space missions and future military space missions.
