170403-N-PO203-049 NATIONAL HARBOR, Md. (April 3, 2017) Program officers and scientists from the Office of Naval Research (ONR) and Naval Research Laboratory (NRL) prepare for the opening of the 2017 Sea-Air-Space Exposition. The Navy League’s Sea-Air-Space Exposition was founded in 1965 as a means to bring the U.S. defense industrial base, U.S. private-sector companies and key military decision makers together for an annual innovative, educational, professional and maritime-based event. Sea-Air-Space is 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.
