How to bid on the Radiological Detection System (RDS) RFI from the Dept of Defense

What the agency is buying and why it matters

The Department of Defense is issuing a Request for Information (RFI) to identify companies capable of manufacturing, testing, and delivering a rugged Radiological Detection System (RDS). This system is intended to replace several legacy radiological survey meters used by the US Army, Navy, Air Force, Marine Corps, Coast Guard, and Special Operations Command.

The goal is to provide a joint solution that addresses parts obsolescence, increases capability, reduces life-cycle costs, and ensures common, interoperable equipment. This RFI is for planning purposes only and is not a solicitation for a contract.

Key dates and what happens at the deadline

This RFI was published on August 18, 2026. Responses are due by September 17, 2026, at 4:30 PM ET. This is an RFI, so no contract will be awarded at this time. The government will use the information gathered for planning future procurements.

Who this opportunity suits

This RFI is suitable for manufacturers of hazard-detecting instruments and apparatus (PSC Code 6665) and other measuring and controlling devices (NAICS code 334519). Companies that can provide complete radiological detection systems, base units, or individual probes are encouraged to respond.

The government is particularly interested in alternative technologies, Commercial-Off-The-Shelf (COTS) solutions, and innovative designs, even if they do not currently meet every specific metric of the RDS Performance Specification. If your system deviates from the P-Spec but offers rugged, modular radiation detection capabilities, you should consider responding.

How to respond

To access the RFI, click “View original source” on the portal. If the first click takes you to the portal's homepage, click it again to go directly to the bid. You may need a free account to view documents, though this is not always required.

Your response should describe compliant systems, alternative commercial technologies, or a plan and timeline to meet the requirements, including any necessary system modifications or design refinements. Proprietary information should be clearly marked.

Practical tips for preparing a competitive response

When responding to an RFI, focus on clearly articulating your firm's capabilities and how they align with the agency's stated needs. Even though this is not a solicitation for a contract, a well-prepared response can position your company favorably for future opportunities.

If your system does not fully meet the current performance specifications, provide a detailed engineering roadmap and timeline for achieving compliance. Highlight any unique benefits or innovative aspects of your technology, especially if they offer operational advantages or cost savings. Ensure all proprietary information is clearly marked to protect your intellectual property.
