thumb|A model of the RD-180
The RD-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 RD-180 is derived from the RD-170 line of rocket engines, which were used in the Soviet Energia launch vehicle. The engine was developed for use on the US Atlas III and Atlas V launch vehicles and first flew in 2000. It was never used on any other rocket. The engine has flown successfully on all six Atlas III flights and on 99 Atlas V flights, with just a single non-critical failure in March 2016.
