[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 ...
First flight of a Dual-Engine Centaur on Atlas V. First orbital test flight of Starliner. Planned to visit ISS, but an anomaly with the Starliner vehicle left the spacecraft in too low an orbit to do so. The Atlas V rocket performed as expected and thus the mission is listed as successful here. [160] 82 10 February 2020, 04:03 411 AV-087
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. Atlas V is being phased out due to the national security implications of reliance on the Russian-built engine, [ 1 ] which became a concern after the Russian annexation of Crimea .
Atlas was a liquid propellant rocket burning RP-1 kerosene fuel with liquid oxygen in three engines configured in an unusual "stage-and-a-half" or "parallel staging" design: two outboard booster engines were jettisoned along with supporting structures during ascent, while the center sustainer engine, propellant tanks and other structural ...
