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

The contract pertains to the provision of a Self-Propelled Modular Transporter (SPMT) designed for the Exploration Upper Stage (EUS) program. The SPMT is described as a transport vehicle that can function as either a single unit or a combination of modular vehicles that are structurally, electronically, and hydraulically integrated to operate as one. The transporter deck dimensions are specified as 22.75 feet wide plus up to 2 feet, and 60 feet long plus up to 4 feet, with the capability of supporting a maximum payload weight of 500,000 pounds. The SPMT’s design allows for either a singular structural deck or multiple modular segments that combine to form a unified structural deck, ensuring the system behaves as an integrated unit. This flexibility enhances its utility for transporting heavy and oversized components. The solicitation was posted by the Marshall Space Flight Center under the NAICS code 336120 and is focused on addressing transportation needs for NASA’s exploration missions.
