United Launch Alliance’s Vulcan Centaur
ULA’s Vulcan Centaur is yet another heavy-lift launch vehicle that’s overdue, as it was originally supposed to fly in 2020 but is currently scheduled to debut in December of this year. The two-stage rocket will feature multiple configurations depending on the mission, including a basic stack capable of delivering 10.6 tons to LEO and a heavy configuration capable of delivering 27 tons to LEO. A Centaur V will comprise the rocket’s upper stage, while two BE-4 engines, built by Blue Origin, will power the first stage (delays in developing this super powerful methane engine is why the rocket has not yet flown).
“ULA’s Atlas and Delta rockets have served as the backbone for American space launch for decades and our next-generation rocket will advance this rich heritage,” Tory Bruno, ULA CEO, said in a 2019 statement. “Vulcan Centaur will provide higher performance and greater affordability while continuing to deliver our unmatched reliability and precision.”
