Atlas family
Atlas V 511
Atlas V is an expendable launch system in the Atlas rocket family. It was formerly operated by Lockheed Martin and is now operated by United Launch Alliance (ULA), a joint venture with Boeing. Each Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage. The RD-180 engines are provided by RD Amross, while Aerojet Rocketdyne provides both the RL10 engines and the strap-on boosters used in some configurations. The 511 version uses a 5m wide fairing, 1 solid rocket booster and one engine on the Centaur stage.
Atlas V 511 is built by United Launch Alliance of the United States. Company background, funding, contracts and news for this operator are tracked on Space Index. It first flew on 21 January 2022 and last flew on 21 January 2022.
