The F.E. Warren ICBM & Heritage Museum, 7405 Marne Loop, F.E. Warren AFB, WY 82005, has two missions. The primary mission is to explain the development of the ICBM from the Atlas to the present day Minuteman III missile. The second mission is to tell the story of the oldest active base in the Air Force system and to interpret rich heritage of the base and region from 1867 to the present day. The museum is housed in the 1894 Post Headquarters building, one of several hundred on the base listed on the National Register. Exhibits offer a unique look at how the base has grown and changed over the years. Lithographs of historic buildings and quarters, ornaments, books and many other gifts are available at the bookstore. The museum is open 8 a.m. to 4 p.m. weekdays. But though the museum is open to the general public, Warren Air Force Base is not. Prospective visitors must call 48 hours in advance, and provide the following information: driver's license number and date of issue, date of birth and full name, including middle name.
