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.
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]
The booster would utilize multiple Raptor engines, similar to the use of nine Merlin 1s on each Falcon 9 booster core. [17] The following month, SpaceX confirmed that as of March 2014, all Raptor development work is exclusively on this single very large rocket engine, and that no smaller Raptor engines were in the current development mix.

The Russian RD-180 engine also employs a staged-combustion rocket engine cycle. Lockheed Martin began purchasing the RD-180 in circa 2000 for the Atlas III and later, the V , rockets. The purchase contract was subsequently taken over by United Launch Alliance (ULA—the Boeing/Lockheed-Martin joint venture) after 2006, and ULA continues to fly ...
The liquid oxygen and kerosene engine met all performance requirements for both government and commercial missions. The maiden launch of the Atlas V rocket equipped with the RD-180 engine occurred in 2002. Energomash committed to delivering a total of 101 RD-180s for the fixed price of one billion dollars.

On November 24, 2013, Elon Musk stated that the engine was actually operating at 85% of its potential, and they anticipated to be able to increase the sea-level thrust to about 730 kN (165,000 lbf) and a thrust-to-weight ratio of 180. [31] This version of the Merlin 1D was used on Falcon 9 Full Thrust and first flew on Flight 20.
