Also known as: MS-IVB · Saturn S-IVB
- 1The S-IVB served as the third stage of the Saturn V rocket and the second stage of the Saturn IB.
- 2The stage was manufactured by the Douglas Aircraft Company.
- 3Propulsion is provided by a single J-2 rocket engine.
- 4During lunar missions, the engine is ignited twice to complete its flight profile.
- 5The first burn occurs to achieve Earth orbit insertion following the cutoff of the previous stage.
- 6The second burn is performed to execute the translunar injection maneuver.
The S-IVB was the third stage on the Saturn V and second stage on the Saturn IB launch vehicles.

third stage of the Saturn V launch vehicle
The Lunar Module was housed within the Spacecraft-Lunar Module Adapter atop this stage, which performed the Trans-Lunar Injection burn to send the spacecraft toward the Moon.
The S-IVB was the third stage on the Saturn V and second stage on the Saturn IB launch vehicles. Built by the Douglas Aircraft Company, it had one J-2 rocket engine. For lunar missions it was fired twice: first for Earth orbit insertion after second stage cutoff, and then for translunar injection (TLI).
