U.S. Naval War College’s National Security Affairs (NSA) Department is one of the nation’s largest and most vibrant graduate programs in national and international security studies. Our rigorous curriculum prepares mid-career security professionals for the ever-evolving global security environment.

Graduate-Level Decision Making

Our NSA department offers core courses for Naval War College’s master’s degree programs: national security decision making (NSDM) and theater security decision making (TSDM). These eight-credit courses provide a broad foundation in contemporary security studies, as well as emphases on international relations, regional studies, foreign policy analysis, and leadership.

The NSDM course, designed for senior-rank students, has more of a global focus, whereas the TSDM course, geared toward intermediate-rank students, emphasizes regional security challenges.

Our Students and Faculty

Our students are typically intermediate- and senior-rank officers from all of the U.S. armed services as well as military officers from more than 60 partner countries and civilians from U.S. government agencies. Our faculty is just as diverse, comprised of scholars, practitioners, and active-duty officers.

Each year, we invite a variety of visiting practitioners, many of whom are renowned scholars or policy analysts, to share their expertise.
