Pictured is the Saturn V S-IC-T stage (static testing stage) on a transporter showing its forward end in building 4705 at the Marshall Space Flight Center (MSFC). This stage underwent numerous static firings at the newly-built S-IC Static Test Stand at the MSFC west test area. The S-IC (first) stage used five F-1 engines that produced a total thrust of 7,500,000 pounds as each engine produced 1,500,000 pounds of thrust. The S-IC stage lifted the Saturn V vehicle and Apollo spacecraft from the launch pad.
