The RD-180 used on the Atlas V replaced the three engines used on early Atlas rockets with a single engine and achieved significant payload and performance gains. This engine had also been chosen to be the main propulsion system for the first stage of the now cancelled Russian Rus-M rocket.
The RD-214 was soon superseded by the RD-216 and later variants, which used a hypergolic combination of UDMH and Nitric Acid. This line of development later led to the highly successful UDMH/N 2 O 4 engines RD-253 and RD-275 used on the Proton launch vehicles – these were the most powerful hypergolic engine of its time, and remains in ...
The roots of the RD-180 rocket engine extend to the Soviet Energia launch vehicle. The RD-170, a four-chamber engine, was developed for use in the strap-on boosters for this vehicle, which ultimately launched the Buran orbiter. This engine was scaled down to a two-chamber version by combining the RD-170's combustion devices with half-size ...
The RD-107 and RD-108 engines are produced at the JSC Kuznetsov plant in Samara, Russia, under the supervision of the Privolzhskiy branch of NPO Energomash, also known as the Volga branch.
