ADC50 Summit + Celebration

ADC50 is a three-day, integrated celebration of Association of Defense Communities (ADC)’s 50th anniversary, May 11–13, 2026, in Washington, DC. Bringing together a special edition of the Defense Communities National Summit and our signature anniversary event, A Celebration of America’s Defense Communities, ADC50 will convene more than 1,500 leaders from the Department of War (DOW), Congress, installations, industry, and communities. This once-in-a-generation moment will honor five decades of partnership and rally the nation around a simple truth: national security starts at home, in the defense communities whose strength, resilience, and unwavering support allow missions—and military families—to thrive.
