WASHINGTON (NNS) -- 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 7-9. 

Historians, curators and scientists will be on hand to talk about historic events and how the Navy uses the latest technology to conserve artifacts for future generations. They will also show some of the historic artifacts NHHC is conserving.

This year the SAS Expo's theme is "The Sea Services: Forward. Mobile. Ready." To complement the SAS Expo theme, NHHC will be presenting the exhibit: "D-Day at 70: A History Lesson in Forward. Mobile. Ready."

The exhibit will present historical artifacts and information from the Collections Management and Histories and Archives divisions of NHHC and the National Museum of the U.S. Navy. Artifacts include video footage of sunken craft off the coast of Normandy, the first Navy flag flown after D-Day, sand from Omaha Beach, a medallion from the USS Forrestal, a showcase of integration during WWII, and subject matter experts available to discuss the significance of the operations then, and artifacts present. 

During the event NHHC's social media team will live tweet from the exhibit. Join the conversation using #NavyHistory and #SAS14. Follow NHHC on Facebook at www.facebook.com/USNHistory/ and on Twitter @USNHistory.
