The U.S. Air Force intends to award a sole-source, firm-fixed-price contract to SAE International for a one-time purchase of technical papers and journal articles, plus an annual SAE Aerospace Complete Collection with a base year and three option years. This is a presolicitation notice only, not a request for proposals, and no solicitation documents exist. Performance is intended at SAE International’s location in Warrendale, PA. No budget amount or submission timeline is specified. Interested vendors who believe they can meet the requirement must submit a complete technical package with clear evidence of capability to the Contracting Officer.
