The Saturn V Second Stage contained five J-2 engines. After the first stage was discarded, the second stage burned for approximately 6 minutes taking the vehicle and payload to 115 miles altitude. The second stage was also discarded. The second stage, powered by five J-2 engines that burned liquid hydrogen and liquid oxygen, was provided by the Rockwell International Corporation. Its engines ignited in fight after the first stage dropped away. The second stage performed for 6-112 minutes, reaching a height of 115 statute miles, 935 miles downrange, and a speed of 15,500 miles-per-hour in its Apollo configuration.
