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.
The engine on the third stage(S-IVB) was also mounted on the gimbal.
The gimbal was configured by compact and sturdy universal joint, and was a socket type bearing made of fiberglass and Teflon.
For directing a Apollo spacecraft to reach the Moon orbit, J2 engine has capability of re-ignited during flight.
In addition, the Space Launch System:the next generation of booster currently under development at NASA, improved J2X engine will be used.

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.
