ADC50

ADC50 is a three-day, integrated celebration of 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 Defense (DoD), 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.

The Association of Defense Communities (ADC) builds resilient communities that support America’s military. They are the connection point for leaders from communities, states, the military and industry on community-military issues by enhancing knowledge, information sharing, and best practices. With nearly 300 communities, states, regions, and affiliated industry organizations, ADC represents every major defense community/state in the nation.
