Vulcan Centaur's Centaur V stage: On May 11, 2018, United Launch Alliance (ULA) announced that the RL10 upper stage engine had been selected for ULA's next-generation Vulcan Centaur rocket following a competitive procurement process. [28] Centaur V will normally use the RL10C-1-1, [2] but on Vulcan Centaur Heavy the RL10C-X will be used. [29]
Vulcan Centaur is a heavy-lift launch vehicle [a] developed and operated by United Launch Alliance (ULA). It is a two-stage-to-orbit launch vehicle consisting of the Vulcan first stage and the Centaur second stage.
Centaur-C flew three times between 1964 and 1965, [47] with two failures and one launch declared successful although the Centaur failed to restart. This version was also powered by two RL10A-3 engines. [47] Centaur-D was the first version to enter operational service in 1965 , [47] with fifty-six launches. [48]
He was an associate administrator at NASA Headquarters, whose involvement with Centaur dated back to 1962 and who had headed the Atlas-Centaur and Titan-Centaur Offices in the 1970s. [ 69 ] [ 70 ] Under Stofan, the Lewis Research Center budget went from $133 million in 1979 (equivalent to $450 million 2023) to $188 million in 1985 (equivalent ...
Falcon 9 Block 5, the most prolific active orbital launch system in the world.. This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit.
In July 2020, the first pathfinder BE-4 was delivered to United Launch Alliance for integration testing with Vulcan Centaur. [33] [34] In August 2020, ULA CEO Tory Bruno stated that the second test BE-4 would be delivered soon, followed quickly by the first flight-qualified ones. [35] He noted an ongoing issue with the BE-4's turbopumps.
