This is a Request for Information (RFI) from NASA's Stennis Space Center to gauge industry capabilities and interest in designing and fabricating two high-pressure, vacuum-jacketed cryogenic vessels for liquid oxygen, hydrogen, and methane. The vessels must have a 15,000 psig MAWP, a minimum 500-gallon volume, and operate between -423°F and 100°F, meeting strict ASME code requirements. Responses to this market research are voluntary, will not form a binding contract, and must include a capability statement, past project examples, ASME certifications, and rough cost and schedule estimates. Questions from interested vendors must be directed to the specified contact by April 24, 2026. No specific budget or performance location is detailed in this RFI.
