The S-IC-T stage is hoisted into the S-IC static test stand at the Marshall Space Flight Center. The S-IC-T stage is a static test vehicle not intended for flight. It was ground tested repeatedly over a period of many months proving the vehicle's propulsion system. The 280,000-pound stage, 138 feet long and 33 feet in diameter, houses the fuel and liquid oxygen tanks that hold a total of 4,400,000 pounds of liquid oxygen and kerosene. The two tanks are cornected by a 26-foot-long intertank section. Other parts of the booster included the forward skirt and the thrust structure, on which the engines were to be mounted. Five F-1 engines, each weighing 10 tons, gave the booster a total thrust of 7,500,000 pounds, roughly equivalent to 160 million horsepower.
