During the 2021 legislative session, the Oklahoma legislature approved changing the name of the Museum from the 45th Infantry Division Museum to the Oklahoma National Guard Museum and raising funds to house a new museum building to serve as a home for the newly refocused Oklahoma National Guard Museum.

As the current museum focuses heavily on the 45th Infantry Division’s service during World War II, the new Oklahoma National Guard Museum will focus on telling the entire story of the Oklahoma Air and Army National Guard, from pre-statehood to modern times.
 
In addition to the many new displays, numerous artifacts from the 45th Infantry Division Museum will continue to be on display. There will also be a variety of interactive displays, which will provide more information about Oklahoma National Guard activities than is currently possible.

The Museum’s current building at 2145 NE 36th Street in Oklahoma City will remain open to visitors as long as possible as the new Museum building is built and exhibits are transferred.
