Naval Service Training Command (NSTC) is headquartered in historic Building 1—the iconic “clock tower building”—at Naval Station Great Lakes, the Navy’s largest training installation. More than 25,000 military and civilian personnel work, train, and live here, and its schools and training commands proudly graduate thousands of recruits and Sailors each year.

For over a century, Great Lakes and NSTC’s mission have evolved to meet the needs of an increasingly sophisticated, technology-driven Navy, ensuring today’s Sailors are prepared for tomorrow’s challenges.
