Qualification Details

Fit reasons
  • NAICS alignment with historical contract wins in similar service areas.
  • Scope strongly matches core technical capabilities and delivery model.
Risks
  • Past performance thresholds may require one additional teaming partner.
  • Potential clarification needed on staffing minimums before bid/no-bid.
Next steps

Validate eligibility requirements, assign capture owner, and schedule partner outreach to confirm teaming strategy before submission planning.

Quick Summary

The National Aeronautics and Space Administration (NASA) Marshall Space Flight Center (MSFC) intends to award a sole-source contract to United Launch Alliance (ULA) for Vulcan Centaur V Upper Stages for the Space Launch System (SLS) Artemis IV and Artemis V missions. This action is a Justification for Other Than Full and Open Competition (JOFOC), not a solicitation for proposals.

Scope of Work

NASA/MSFC requires next-generation upper stages for the SLS Block 1 configuration. The procurement includes:

  • Two flight units and one flight spare unit.
  • Associated pre- and post-flight requirements, sustaining engineering, and spare line replacement units.
  • Upper stages must be human-rated (NPR 87205.2B).
  • Specific performance requirements: approximately 60,000 lbs lift capability on orbit, Delta-V greater than 3,050 m/s with three engine ignitions, and functionality for separation and three-axis control after insertion.
  • Axial acceleration not to exceed 2g.
  • Compatibility with existing Ground Support Equipment (GSE) infrastructure for fuel and oxidizer commodities.
  • First upper stage ready for integration no later than nine months prior to launch (L-9 months).

Contract Details

  • Type: Sole-source contract
  • Awardee: United Launch Alliance (ULA)
  • Estimated Period of Performance: Approximately 6 years
  • Estimated Cost: Not specified in the provided text.
  • Set-Aside: Not applicable (sole-source justification)

Submission & Evaluation

This is a justification for a non-competitive award, not a solicitation. Therefore, submission of proposals or evaluation criteria are not applicable.

Additional Notes

The justification cites FAR 6.103-1(c), "Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements." ULA's Centaur upper stage is identified as the only viable source due to its unique qualifications, existing infrastructure, heritage, and minimal modification requirements to meet SLS Block 1 needs. Market research considered ULA's Vulcan Centaur V and Blue Origin's New Glenn Upper Stage, concluding only Centaur meets requirements. Award to any other source would result in substantial duplication of cost and unacceptable schedule delays. The action aligns with Executive Order (EO) 14369, Ensuring American Space Superiority.
