A model of the RD-180. 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 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.

According to Rogozin, Russia has delivered a total of 122 RD-180 engines to the U.S. since 1990s, of which 98 have been used to power Atlas launch vehicles. Russia halts deliveries of rocket ...
The RD-180 engine, developed with Pratt & Whitney Rocketdyne through the RD AMROSS partnership, is a direct descendant of the RD-170 line and is used as the propulsion system for the first stage of Atlas V. [16] The most current engine listed on the NPO Energomash website is the single-chamber RD-191, developed for the Angara and Baikal launch ...
[4] [5] Later in 2014, the US Congress passed a law requiring the US Air Force to "develop a new propulsion system by 2019 to replace the RD-180 engine" that powers Atlas V used by United Launch Alliance (ULA), because the engine is Russian-made, along with the Russian conflict with Crimea. [6] Dynetics is a key partner in development of the ...
A half-sized derivative of the engine, the two-chamber RD-180, powers Lockheed Martin's Atlas V rocket, while the single-chamber derivative, the RD-191, has been used to launch the Korean Naro-1 (as a reduced-thrust variant named the RD-151) and the Russian Angara rocket. The RD-181, based on the RD-191, is used on the Antares rocket. [16]
An RD-180 engine undergoes a test firing at NASA's Marshall Space Flight Center in November 1998. The first stage of Atlas III was derived from that of Atlas II. Its propellant tanks were 3 m (9.8 ft) longer than those on Atlas II, making more propellant available to the engine and increasing the vehicle's performance.
