How to bid on the Radioisotope Identification Detector (RIID) Repair Program for the Air Force
What the Air Force is buying and why it matters
The Department of the Air Force is conducting a market survey, called a Sources Sought or Request for Information (RFI), for its Radioisotope Identification Detector (RIID) Repair Program. This is not yet a contract for purchase, but an inquiry to find capable companies.
The Air Force is looking for firms that can provide sustainment requirements for about 375 SL23-N VeriFinder detectors over five years. This includes maintenance, repairs to Condition Code A, calibration, and software updates. It also covers engineering services, testing, repair procedures related to structural, mechanical, and electrical design, and updates to training and technical manuals. Responding to this RFI is an opportunity to show your company's capabilities for future Air Force contracts.
Key dates and what happens at the deadline
This RFI was published on July 20, 2026. Responses are due by August 15, 2026, at 4:00 PM ET. This deadline is for submitting your company's information to the Air Force Life Cycle Management Center/Human Systems Program Office (AFLCMC/ROU).
After the deadline, the government will review the submitted responses to identify potential sources and for planning purposes. This information helps the Air Force determine if there are enough qualified contractors for a future solicitation.
