Scanning the Horizon: Implications for Navy strategy of national, joint and other services’ strategic trends

This study reviews and assesses strategies, concepts, doctrines, policies, and trends in strategic thinking, as reflected in documents published by five U.S. national security entities:

 National and joint authorities (including the President, the Secretary of Defense (SECDEF), the Office of the Secretary of Defense (OSD), the Chairman of the
Joint Chiefs of Staff (CJCS), the Joint Chiefs of Staff (JCS), and the Joint Staff)

 The U.S. Army, Air Force, Coast Guard and Marine Corps From these reviews and assessments, the study then derives implications and recommendations for a potential U.S. Navy refreshment of the CS 21 strategy.

Since most of the Navy's capstone documents (such as CS 21) and their counterparts in other services and agencies are unclassified, this study was limited to examining unclassified documents.2 This also enables the study to reach a wider potential readership, enhancing its potential utility.
