Modern Day Marine 2027 in Washington D.C.

Modern Day Marine is the flagship military exposition and conference dedicated solely to the United States Marine Corps market. Held annually in Washington D.C., the show floor spans more than 84,000 square feet across Halls A & B of the Walter E. Washington Convention Center, hosting over 400 exhibitors that present the newest warfighting technology, unmanned systems, ground equipment, and defense services. The event is co-hosted by Marine Corps Base Quantico, the Marine Corps League, and the Marine Corps Association, and draws key decision-makers including the Commandant of the Marine Corps, senior DoW officials, program managers from Marine Corps Systems Command, and international military delegations. Attendees benefit from daily main briefing center sessions, the OBJ1 Wargaming Convention, the Warfighting Pavilion, the Drone Zone, and dedicated acquisition briefings. Beyond the expo floor, Modern Day Marine hosts networking and recognition events such as the Congressional Breakfast, Warfighting Reception, Modern Day Marine Honors, and the Semper Fidelis Reception. The exposition is a professional trade event and is not open to the general public; registration and a valid government-issued ID are required for badge pickup. For hotel booking, the show's official housing block typically opens in January; attendees are advised to reserve rooms near the Walter E. Washington Convention Center early, as the April dates overlap with the peak spring conference season in Washington D.C.
