The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...

Later flights will switch to an RS-25 variant optimized for expended use, the RS-25E, which will lower per-engine costs by over 30%. [32] [33] The thrust of each RS-25D engine has been increased from 492,000 lbf (2,188 kN), as on the Space Shuttle, to 513,000 lbf (2,281 kN) on the sixteen modernized engines. The RS-25E will further increase per ...
The RS-28 Sarmat (Russian: РС-28 Сармат, [7] named after the Sarmatians; [8] NATO reporting name: SS-X-29 [9] or SS-X-30 [10]), often colloquially referred to as Satan II by media outlets, is a three-stage Russian silo-based, liquid-fueled, HGV-capable and FOBS-capable super-heavy intercontinental ballistic missile (ICBM) produced by the Makeyev Rocket Design Bureau.
The RS-26 is based on RS-24 Yars, and constitutes a shorter version of the RS-24 with one fewer stages. [5] [6] The development process of the RS-26 has been largely comparable to that of the RSD-10 Pioneer, a shortened derivative of the RT-21 Temp 2S. Deployment of the RS-26 is speculated to have a similar strategic impact as the RSD-10. [7]
To achieve this, the RS-68 has 80% fewer parts than the multi-launch RS-25 Space Shuttle Main Engine (SSME). [4] The adverse consequences of this simplicity were a significantly lower thrust-to-weight ratio and a 10% lower specific impulse compared to the SSME. The benefit of this simplicity is the RS-68's reduced construction cost. [4]
The RD-0120 (Russian: Ракетный Двигатель-0120, romanized: Raketnyy Dvigatel-0120, lit. 'Rocket Engine 0120', GRAU index: 11D122) was the Energia core rocket engine, fueled by LH 2 /LOX, roughly equivalent to the Space Shuttle Main Engine (SSME).
