This is a 1:20 scale model of a proposed advanced radar reconnaissance satellite. The U.S. government has declassified very little information on space-based radar-imaging systems used for reconnaissance, and it is not known whether this system or a similar one was ever tested or deployed.
RCA made the model and donated it to the Museum in 1975.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
