US To Stop Using Russian Rocket Engine RD-180 In Mid-2020s - United Launch Alliance
Daniyal Sohail Published September 16, 2020 | 07:40 AM
MOSCOW (UrduPoint News / Sputnik - 16th September, 2020) US company United Launch Alliance (ULA) plans to end operation of the Atlas-5 launch vehicle with the Russian RD-180 engine in the mid-2020s, Julie Arnold, an ULA spokeswoman, told Sputnik.
The RD-180 engine is manufactured at the Energomash rocket engine manufacturer (an enterprise of Russian state space corporation Roscosmos) and is used in the first stage of the Atlas-5 rocket.
ULA provides launch services with Atlas-5.
According to Energomash, 116 RD-180 engines have been sent to the United States, of which 91 have already been used. In 2020, delivery of six more RD-180s is expected.
The United States is developing a Vulcan launch vehicle to replace the Atlas-5, the first stage of which will be equipped with the BE-4 engines by Blue Origin.
There are plans to use the RD-180 in Russia - in the medium-lift Soyuz-6 rockets and the super-heavy Yenisei.
