About Sea-Air-Space

The Navy League’s Sea-Air-Space Exposition was founded in 1965 as a means to bring the U.S. defense industrial base, private-sector U.S. companies and key military decision-makers from the sea services together for an annual innovative, educational, professional event located in the heart of Washington, D.C. 

Sea-Air-Space is now the largest maritime exposition in the U.S. and continues as an invaluable extension of the Navy League’s mission of maritime policy education and sea service support.

At Sea-Air-Space, our exhibitors and attendees experience:

  • Numerous networking and business-generating opportunities with policy-makers, purchasing agents and end users.

  • Professional development opportunities with the most up-to-date information regarding the current state of the defense industry as well as a vision of the future.
  • Dynamic luncheon and keynote speakers provide an open forum to fully disclose up-to-the-minute information and paint a realistic picture of the future.

The Navy League of the United States, founded in 1902 with the support of President Theodore Roosevelt, is a nonprofit civilian, educational and advocacy organization that supports America’s sea services: the Navy, Marine Corps, Coast Guard and U.S.-flag Merchant Marine.
As part of its mission focus, the Navy League of the United States:

  • Enhances the morale of sea service personnel and their families through national and council level programs.
  • Provides a powerful voice to educate the public and Congress on the importance of our sea services to our nation’s defense, well-being and economic prosperity.
  • Supports youth through programs, such as the U.S. Naval Sea Cadet Corps, Junior ROTC and Young Marines, that expose young people to the values of our sea services.

The Navy League has more than 30,000 individual members, more than 200 councils and, more than 240 corporate and community affiliate members.

Food and beverage are allowed in your booth, but all staff and guests must be seated while eating. You may want to serve your food and beverage in a meeting room.

Staff member count will remain the same for your booth size. Fifty percent capacity, which is the current restriction for large gatherings in the state of Maryland, falls within the range of our normal attendance in the entire exhibit hall.

Booths and aisles will look the same as in past years. Currently, the state of Maryland does not have any restrictions for the exhibit hall other than we maintain 50% of total capacity.

Meeting rooms are available on a limited basis for 2022. Please book now by contacting Senior Director of Meetings and Events Kevyan Sly.

Hotel rooms at the Gaylord National Harbor are no longer available. For local options, please visit our Attend page
