Vulcan is a next generation heavy-lift launch vehicle under development by the United Launch Alliance (ULA) to meet the demands of the United States Air Force's National Security Space Launch (NSSL) competition and launch program.

The maiden flight is planned to take place in July 2021, launching Astrobotic's Peregrine lunar lander.
