To further enhance payload capacity, the Vulcan Centaur can be equipped with up to six GEM 63XL SRBs (solid rocket boosters) from Northrop Grumman—a lengthened version of the GEM 63 SRBs used on the Atlas V. [7] [24] A single-core Vulcan Centaur with six SRBs delivers heavy-lift capabilities comparable to the larger and more expensive three ...
First fired in 2020, it is used on the Vulcan launch vehicle beginning with the first launch on January 8, 2024. [4] [9] [10] Up to 6 of the boosters will be mounted on a single Vulcan core, depending on customer needs. [11] It is currently used on Vulcan Centaur rocket. [2]
On 12 August 2019, ULA submitted Vulcan Centaur for phase 2 of the USAF's launch services competition. As of July 2024, Vulcan Centaur has completed one certification flight launch and another is left be fully certified for national security launches.
The RL10 is a liquid-fuel cryogenic rocket engine built in the United States by Aerojet Rocketdyne that burns cryogenic liquid hydrogen and liquid oxygen propellants. Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum.

[note 2] Liquid-propellant rockets have a motor that feeds liquid propellant(s) into a combustion chamber. Most liquid engines use a bipropellant , consisting of two liquid propellants (fuel and oxidizer) which are stored and handled separately before being mixed and burned inside the combustion chamber.
The Vulcan Centaur is a heavy-lift launch vehicle developed by ULA integrating technology from both its prior Atlas and Delta rocket families along with advancements. Vulcan has been designed to meet the requirements of the National Security Space Launch (NSSL) program and be capable of achieving human-rating certification to allow the launch ...
