The United Launch Alliance’s (ULA) Vulcan Centaur rocket successfully completed its inaugural national security mission, launching the Navigation Technology Satellite-3 into geosynchronous Earth orbit (GEO). This marks a significant milestone for the National Security Space Launch (NSSL) program, replacing the retired Delta IV Heavy rocket and ending US reliance on Russian-made rocket engines.
The two-stage, heavy-lift launch vehicle deployed a payload of approximately 14,300 pounds to GEO, showcasing its capacity and capabilities. ULA secured 26 missions under NSSL’s Phase 2 contract, with further contracts expected under Phase 3.
Vulcan Centaur, built by ULA, is designed to provide flexibility to the nation’s decision makers as they combat adversaries in space operations. The rocket has an opportunity to build on the legacy of Delta IV Heavy and serve as a backbone for the NSSL program.
The mission was a success after years of certification snags, with Colonel Jim Horne praising ULA’s team for their dedication. Gary Wentz, ULA vice president of government and commercial programs, said “National security begins at liftoff,” highlighting Vulcan’s capabilities.
ULA is one of several launch providers selected for NSSL contracts, including SpaceX, Blue Origin, and Northrop Grumman. The competition is heating up, but Tuesday’s success may be the first step toward cementing Vulcan as the Space Force’s new workhorse.
The National Security Space Launch program has seen increased pressure with more companies participating in Phase 2 and Phase 3 contracts. However, ULA’s successful launch marks an important development for the program, demonstrating its capabilities and potential to succeed.
