Read the Report — The space environment is of great importance to the United States. However, space remains just unfamiliar enough to decision makers so as to introduce hesitation in those charged with strategic decisions. One useful way of addressing the strategic oddity of space is to examine it anew through the familiar lens of sea power theory. In particular, studying the works of Alfred Thayer Mahan and Julian Corbett can provide essential guidance, informing the strategic, commercial, and military aspects of space. President John F. Kennedy turned to such an analogy in 1962 when he outlined his vision for why the United States should undertake manned exploration of the moon. “We set sail on this new sea,” he declared, suggesting that pioneering efforts in space could be understood within the more familiar context of nautical achievement. 1 President Kennedy understood the importance of space power, and so must defense policymakers today. To do so, they would be well advised to review the theories of sea power as a means of developing a framework for space.
