Exploration Upper Stage (EUS) Self-Propelled Modular Transporter (SMPT)

The Self-Propelled Modular Transporter (SPMT) is designed to function as a single integrated transport system, whether as one unit or multiple modular segments that are structurally, electronically, and hydraulically coupled to operate as one cohesive vehicle. The transport deck must measure 22.75 feet in width with a tolerance of +2 feet, -0 feet, and 60 feet in length with a tolerance of +4 feet, -0 feet, ensuring precise dimensions for transporting large and heavy payloads. The SPMT must support a maximum payload capacity of 500,000 pounds and maintain structural integrity across all configurations, with modular components forming a unified structural deck that behaves as a single entity during operation. This SPMT is specifically intended for the Exploration Upper Stage (EUS) program under the National Aeronautics and Space Administration’s Marshall Space Flight Center. The procurement is forecasted with a NAICS code of 336120, indicating its classification within the aerospace product and parts manufacturing industry. While no solicitation number has been issued yet and the posting date is listed as May 25, 2026, the contract is pending formal release and will likely involve a competitive bidding process under federal acquisition regulations. The place of performance and point of contact details have not been provided, suggesting the project is still in the early planning stages with further details to be announced upon formal solicitation.
