This is a sole-source Request for Quotation intended to award to Advantor Systems for an intrusion detection system (IDS) for the 185th Air Refueling Wing, with performance in Sioux City, Iowa. The NAICS code is 561621 with a small business size standard of $25 million, and the government expects to make a single award. Offerors must submit a completed vendor information sheet, adequate technical documentation, and maintain active SAM registration with required representations and certifications to be considered. Funds are not currently available, and quoted prices must remain valid through 30 September 2026. Interested parties should note that this acquisition is being pursued on a sole-source basis, limiting competitive opportunity.
