The RD-180 (Russian: Ракетный Двигатель-180 (РД-180), romanized: Raketnyy Dvigatel-180, lit. 'Rocket Engine-180') is a rocket engine that was designed and built in Russia. It features a dual combustion chamber , dual- nozzle design and is fueled by a RP-1 / LOX mixture.
[80] [81] By 18 December 2021, Raptor 2 had started production. [82] By November 2022, SpaceX produced more than one Raptor a day and had created a stockpile for future launches. [83] Raptor 2s are produced at SpaceX's McGregor engine development facility. Raptor 2s were achieving 230 t f (510,000 lbf) of thrust consistently by February 2022 ...
Notable examples are the RD-107/RD-108 engines used on the R-7, Molniya and Soyuz rocket families, and the RD-170, RD-171 and RD-180 engines used on the Energia, Zenit and Atlas V launch vehicles. As of July 2013 [update] , the company remained largely owned by the federal government of Russia , but RSC Energia owned approximately 14% of the ...

An 18 ft diameter stage could have conceivably accepted dual RD-180 engines. The resulting conceptual heavy-lift vehicle was called "Atlas Phase 2" or "PH2" in the 2009 Augustine Report . An Atlas V PH2-Heavy (three 5 m stages in parallel; six RD-180s) along with Shuttle-derived , Ares V and Ares V Lite, were considered as a possible heavy ...
RD-171 (and its RD-171M successor), -180 and -191 are derivatives of RD-170. RD-0124—a series of oxygen/kerosene engines used in the second stage of Soyuz-2.1b rocket as well as in upper stages of Angara series rockets. YF-100—Chinese engine developed in the 2000s; used on the Long March 5, Long March 6, and Long March 7. [12]
