Naval History and Heritage Command (NHHC) headquartered at the Washington Navy Yard is bringing a bit of history and historic expertise to the Sea Air Space (SAS) Exposition at the Gaylord National Convention Center in National Harbor, Md., April 13-15.

Historians, curators and scientists will be on site at booth #2755 to talk about historic events and how the Navy uses the latest technology to conserve artifacts for future generations. They will also show a sampling from NHHC collection of more than 300,000 historic artifacts.

This year the SAS Expo's theme is "Game-Changing Technology." To complement the SAS Expo theme, NHHC will present an exhibit that will feature Navy innovation and highlight naval history during the last 50 years.

The exhibit will showcase historical artifacts and information from NHHC’s Collections Management, Histories, Archives Divisions, and the National Museum of the U.S. Navy. Artifacts include a model of a World War I MK6 mine (as well as historic photos of Sailors moving MK6 mines in Inverness, Scotland during the war), a scale model of the World War II cruiser USS Houston (CA 30), combat art reproductions, a model Lego ship, posters detailing our Underwater Archaeology Branch’s conservation work on the 1890’s Howell Torpedo, the survey of the Normandy beach as well as several recovered artifacts. Subject matter experts will also be available to discuss Navy heritage and artifacts.

NHHC's social media team will live tweet from the exhibit. Join the conversation using #NavyHistory, #SAS15, #NavalHistory, and/or #OurHeritage. Follow NHHC on Facebook at and on Twitter @USNHistory.
