This is the only surviving reconnaissance version of the B-36 and was assigned to the 28th SRW at Rapid City AFB, SD (Ellsworth AFB after June 1953) from 1952 to 1957. In 1957, it was reassigned to Chanute Air Force Base, IL, and was used as a ground instructional airframe. After retirement, it was placed on display at the Chanute Aerospace Museum but now resides at the superb Castle Air Museum.
