Overview
- The museum hosted a ribbon‑cutting on Thursday and opened to the public at 10 a.m. on Friday, June 12, 2026.
- The new facility at 3301 Northeast Grand Blvd. occupies about 39,375–40,000 square feet and replaces the older armory home of the 45th Infantry Division Museum.
- Inside the building are roughly 20,000 square feet of new exhibition space with modern graphics, audio‑visual components and interactive displays designed for visitors of all ages.
- The campus includes large outdoor static displays — including a fighter jet, tanks and other vehicles — plus climate‑controlled storage and a 10,000‑square‑foot event and education center for school groups and community programs.
- State lawmakers approved funding for the expansion in 2021, and museum leaders say the site will preserve more Guard history, surface new stories of Oklahoman veterans and serve as a national benchmark for Guard museums while remaining free and open to the public.
