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.
