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 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. [1] [2] [3] Under RD AMROSS, Pratt & Whitney is licensed to produce the RD-180 in the United States.
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]
In April 2024, Musk shared the performance achieved by SpaceX with the Raptor 1 engine (sea level 185 t f, Rvac 200 t f) and Raptor 2 engine (sea level 230 t f, Rvac 258 t f) along with the target specifications for the upcoming Raptor 3 (sea level 280 t f, Rvac 306 t f) [50] [51] and said SpaceX would aim to ultimately achieve over 330 tonnes ...

The RD-181 is based on the RD-191 and is adapted for integration on the Antares rocket. While the RD-193 was designed as a close replacement for the NK-33, on 17 December 2014, Orbital Sciences announced that it would use the NPO Energomash RD-181 on the version 2 Antares launch vehicle and had contracted directly with NPO Energomash for up to ...
The fuel pump delivered 15,471 US gallons (58,560 litres) of RP-1 per minute while the oxidizer pump delivered 24,811 US gal (93,920 L) of liquid oxygen per minute. Environmentally, the turbopump was required to withstand temperatures ranging from input gas at 1,500 °F (820 °C) to liquid oxygen at −300 °F (−184 °C).
