This is the business end of the first stage of the giant Saturn V rocket on display in the Saturn V Center at the Kennedy Space Center near Titusville, Florida. This stage is designated S-IC-T, with S standing for Saturn, IC being the third design of the first stage, and T indicating that it was a test article rather than a flight-ready stage. This booster was given the serial number of 500F. It was used to verify handling and fit testing during manufacturing, shipping, and processing at the cape. It was stacked and rolled out to a launch pad in the spring of 1966 as part of a full dress rehearsal of the steps to get ready for a Saturn V launch. It sat for many years out in the open next to the Vehicle Assembly Building. It is now on display indoors along with the 2nd and 3rd stages from vehicle SA-514.
