J2 Engine
- Width : 6ft 8.5in (2.04m)
- Length : 11ft 1in (3.38m)
- Thrust(altitude) : 230,000lb (104.33ton)
- Rated run duration : 500sec.
- Manufacturer : North American Rockwell Corp., Rocketdyne Div. Canoga Park, Calif.
The J2 engine was fueled by liquid oxygen and liquid hydrogen,
5 group in the second stage(S-II), and one in the third stage(S-IVB) are/is used on Saturn V.
On the second stage(S-II), the center engine was fixed, and four other were mounted on the gimbal and performing attitude control of the rocket.

Rocketdyne: Powering Humans into Space
AIAA Education November 30, 2005 USD39.95
No one had written an overall history of Rocketdyne - the professional historians said there was not enough preserved documentation for them to write a proper history book - so I determined to visit key survivors of the glory days of Rocketdyne to record their memories, add my own insight as a member of the team, and preserve the history of how large liquid propellant rocket engines evolved at Rocketdyne and why the team was so successful.
