S-IVB-200 Stage
The S-IVB was built by the Douglas Aircraft Company at Huntington Beach, California. The S-IVB-200 model was similar to the S-IVB-500 third stage used on the Saturn V, with the exception of the interstage adapter, smaller auxiliary propulsion control modules, and lack of on-orbit engine restart capability. It was powered by a single J-2 engine. The propellant and oxidizer tanks shared a common bulkhead, which saved about ten tons of weight and reduced vehicle length over ten feet.

Famous quotes containing the word stage:
“Their rebukes have never made me angry, because I have always wondered why they did not rebuke me more. They should have. Their friendly praise has been one of the sweetest, most warming things in my life in the theater. I do go on the stage unafraid of them and with love in my heart for them.”
—Minnie Maddern Fiske (1865–1932)
