Request For Proposal (RFP) NASA Agency-wide Acquisition of Nitrogen and Oxygen 4 (NANO 4)

UPDATE - 10/07/2026

The National Aeronautics and Space Administration (NASA) John F. Kennedy Space Center is pleased to release the 2027 NASA Agency-wide Acquisition of Nitrogen and Oxygen (NANO) 4 opt-in opportunity as described in the original NANO 4 Request for Proposal (RFP), Sections 2.9, IDIQ CLIN Pool Opt-in, and 2.9.2, IDIQ CLIN Pool Opt-in After Award.

The NANO 4 RFP was issued on March 4, 2024, and the original solicitation (as revised) remains open throughout the ordering period through the use of innovative provisions as prescribed in Section 2, Clause 2.9, IDIQ CLIN Pool Opt-in, and Clause 2.9.2, IDIQ CLIN Pool Opt-in After Award. The NANO 4 contract’s ordering period remains valid through June 30, 2029.

The RFP resulted in the award of six indefinite delivery (ID) fixed price with Economic Price Adjustment (FPEPA) requirements contracts with fixed price delivery orders for the supply of liquid nitrogen and liquid oxygen in support of operations at agency centers and facilities across the United States. NASA made award to the following companies: Air Products and Chemicals, Inc., Airgas USA LLC (Central), Airgas USA LLC (South), Linde, Inc., Nippon Sanso Matheson, Inc. (formerly Matheson Tri-gas, Inc.), and Messer LLC.  

Each year during the life of the solicitation and at the time established via synopsis, the Government will accept proposals from new entrants for each IDIQ subCLIN location and the Government will also accept proposals from existing NANO 4 contractors for each additional proposed IDIQ subCLIN location. A new entrant does not hold a current NASA liquid nitrogen or liquid oxygen contract.

The Government will evaluate the proposals to determine technical acceptability for a specific NASA location. Upon the Government’s determination of technical acceptability, a contract (for new entrants) or contract modification (for existing NANO 4 Contractors) will be executed to add the Contractor to the IDIQ CLIN Pool for the specific NASA location. Thereafter, the Contractor will be eligible to participate in the IDIQ CLIN Pool process described in Section 2.8 for the NASA locations awarded to that Contractor.  All eligible Contractors who are awarded an IDIQ subCLIN for a particular NASA location will have the option to compete for requirements within those IDIQ subCLINs which they are awarded.

The commodities will support current and future aerospace flight, simulation, research, development, testing, and other operations at the following NASA centers and facilities:

Ames Research Center (ARC), Moffett Field, CA 94035;

Glenn Research Center (GRC), Cleveland, OH 44135;
