Rocketdyne J-2 - Wikipedia
The J-2, commonly known as Rocketdyne J-2, was a liquid-fuel cryogenic rocket engine used on NASA 's Saturn IB and Saturn V launch vehicles. Built in the United States by Rocketdyne, the J-2 burned cryogenic liquid hydrogen (LH 2) and liquid oxygen (LOX) propellants, with each engine producing 1,033.1 kN (232,250 lb f) of thrust in vacuum.

J-2X - Wikipedia
The J-2X is a liquid-fueled cryogenic rocket engine that was planned for use on the Ares rockets of NASA's Constellation program, and later the Space Launch System.
It is based on the proven J-2 engine used on the Saturn IB and Saturn V launch vehicle upper stages. It will power both the Ares I upper stage and the Ares V Earth departure stage (EDS).
