"America has enduring national interests in the Polar Regions which include national security, law enforcement, maritime safety, diplomatic, humanitarian aid, scientific research, economic sustainability, and marine environmental protection. As the Polar Regions, and the Arctic in particular, become more attractive to commercial entities and foreign governments, issues of sovereignty, access and mobility will rise to the forefront of the global dialogue. The United States requires assets capable of operating in the Polar Regions to maintain a sovereign presence, protect U.S. interests and respond to calamity. The proposed High Latitude Study is intended to provide the research and analysis required to more clearly define what is needed to address possible expanding requirements. With further study and regular observation, the United States will continue to improve its readiness to achieve national strategic objectives in the Polar Regions."
