. The engine nozzles could gimbal ±10.5° in pitch, and ±8.5° in yaw during ascent to change the direction of their thrust to steer the Shuttle. The normal maximum throttle promocyjny was 104 percent, with 106% or 109% used for mission aborts.

The nozzle is cooled by promocyjny 1,080 interior lines carrying liquid hydrogen and is thermally protected by insulative and ablative material. . RS-25 engines with the two Orbital Maneuvering System (OMS) pods Three RS-25 engines, also known as the Space Shuttle Main Engines (SSME), were mounted on the orbiter's aft fuselage in a triangular pattern. The engine nozzles could gimbal ±10.5° in pitch, and ±8.5° in yaw during ascent to change the direction of their thrust to steer the Shuttle. The titanium alloy reusable engines were independent of the orbiter vehicle and would be removed and replaced in between flights. The RS-25 is a staged-combustion cycle cryogenic engine that used liquid oxygen and hydrogen and had a higher chamber pressure than any previous liquid-fueled rocket. The original main combustion chamber operated at a maximum pressure of 226.5 bar (3,285 psi). The engine nozzle is 287 cm (113 in) tall and has an interior diameter of 229 cm (90.3 in).

During the development program, Rocketdyne determined that the engine was capable of safe reliable operation at 104% of the originally specified thrust. RS-25 upgrade versions were denoted as Block I and Block II. During the development program, Rocketdyne determined that the engine was capable of safe reliable operation at 104% of the originally specified thrust. During the development program, Rocketdyne determined that the engine was capable of safe reliable operation at 104% of the originally specified thrust. 109% thrust level was achieved with the Block II engines in 2001, which reduced the chamber pressure to 207.5 bars (3,010 psi), as it had a larger throat area.
