The Vulcan Centaur is a heavy-lift launch vehicle developed by United Launch Alliance (ULA) to replace the Atlas V and Delta IV Heavy rockets. It represents ULA's entry into the modern era of launch vehicle design.
Development History
Announced in 2014, Vulcan Centaur was designed to:
- Replace ULA's aging Atlas V and Delta IV fleet
- Compete with SpaceX's Falcon 9 and Falcon Heavy
- Eliminate dependence on Russian RD-180 engines
- Provide eventual first-stage reusability
First Flight
The maiden launch occurred on January 8, 2024, carrying the Peregrine lunar lander. Despite being a new rocket, the flight was largely successful, with the only issue being the payload itself experiencing problems unrelated to the launch vehicle.
Technical Features
Engines:
- BE-4 engines (developed by Blue Origin)
- First new American booster engine in decades
- Burns liquefied natural gas and liquid oxygen
Centaur V Upper Stage:
- Upgraded version of the proven Centaur upper stage
- Uses two RL10 engines
- Extended propellant capacity
Solid Rocket Boosters:
- 0, 2, 4, or 6 GEM 63XL solid motors
- Provides configuration flexibility
Future Plans
ULA plans to implement:
- SMART reusability: Engines detach from first stage and are recovered mid-air
- Various configurations for different payload masses
- National security launches
- Commercial satellite missions
Significance
Vulcan Centaur ensures continued American heavy-lift capability and provides much-needed competition in the launch market, while maintaining ULA's reputation for reliability in critical national security missions.
