IDIQ2 & REDDI Flight Providers

Listed below are nine commercial flight providers. Six of these are on contract with NASA through a commercial IDIQ contract (Indefinite Delivery - Indefinite Quantity) to provide test flight services for U.S. Government researchers. If you are a NASA Civil Servant/Contractor, or from another Government Agency, you are able to utilize one of these six IDIQ2 flight providers. If you are not U.S. Government affiliated, you can propose to our REDDI Call for proposals where you are free to propose your own preferred qualified U.S. commercial flight provider (which does not have to be from this list of six). In addition to IDIQ2 flight providers below, the following three have (also) sofar been part of winning REDDI Grants for flight: Exos Aerospace, Integrated Spaceflight Services and Zero Gravity Corporation.
