About Sea-Air-Space
Maritime exposition for the US Navy, bringing together defense industry leaders and military decision-makers.
Sea-Air-Space 2027
The Navy League's Sea-Air-Space Exposition runs 4–7 April 2027 at the Gaylord National Resort & Convention Center in National Harbor, Maryland.
Sea-Air-Space is a maritime exposition in the United States — the annual meeting between the sea services (Navy, Marine Corps, Coast Guard, Merchant Marine) and the defense industrial base that builds for them. Uniformed leadership speak, programme offices brief, and the exhibit floor runs from shipbuilders and missile primes to unmanned maritime systems and C5ISR.
Its position just outside Washington makes it as much a policy event as a trade show: budget season context tends to dominate the keynotes.
