    The concept evolved from a family of Raptor-designated rocket engines (2012) [45] to focus on the full-size Raptor engine (2014). [46] In January 2016, the US Air Force awarded a US$33.6 million development contract to SpaceX to develop a prototype Raptor for use on the upper stage of Falcon 9 and Falcon Heavy. [47] [48]

    Under RD AMROSS, Pratt & Whitney is licensed to produce the RD-180 in the United States. Originally, production of the RD-180 in the US was scheduled to begin in 2008, but this did not happen. According to a 2005 GAO Assessment of Selected Major Weapon Programs, Pratt & Whitney planned to start building the engine in the United States with a ...

    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]

    en.wikipedia.org/wiki/Atlas_(rocket_family)

    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 ...

  9. NK-33 - Wikipedia

    en.wikipedia.org/wiki/NK-33

    The oxygen-rich combustion technology developed for the NK-15 and refined in the NK-33 laid the groundwork for many of the most successful rocket engines in Soviet and Russian history. These include the RD-170, RD-180 and RD-191. While these engines share the oxygen-rich staged combustion cycle, they are not directly related to the NK-33.
