Atlas V was formerly operated by Lockheed Martin, and is now operated by the Lockheed Martin-Boeing joint venture United Launch Alliance. 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 and the RL10 engines by Pratt & Whitney Rocketdyne. SOme configurations also use strap-on booster rockets made by Aerojet. The standard payload fairing sizes are four or five meters in diameter and of various lengths, are made by RUAG Space. Fairings sizes as large as 7.2 meters in diameter and up to 32.3 meters in length have been considered. The rocket is assembled in Decatur, Alabama; Harlingen, Texas; San Diego, California; and at United Launch Alliance's headquarters near Denver, Colorado.
