How to bid on System Delta 84 Missile Warning/Tracking Epoch 3 and 4 for the Air Force
What the Air Force is buying and why it matters
The Department of the Air Force's Space Systems Command (SSC) is seeking industry feedback for its System Delta 84 (SYD 84/MT) Medium Earth Orbit (MEO) Missile Warning / Missile Tracking Epoch 3 and Epoch 4. This initiative aims to develop resilient missile warning and tracking capabilities to support full warfighting needs.
This is a Request for Information (RFI), not a contract opportunity. The government is gathering feedback to shape its acquisition strategy and technical approach for future MEO MWT capabilities. Your input can influence how these critical systems are developed and procured. The government encourages responses covering space vehicles, the ground segment, or digital engineering integration.
Key dates and what happens at the deadline
The RFI was published on August 21, 2026. Responses are due by October 31, 2026, at 7:00 PM ET. This deadline is for submitting your feedback to the government points of contact.
Since this is an RFI, there is no contract award at the deadline. The government will use the submitted information for planning purposes to inform future solicitations for the MEO MWT Epoch 3 and 4 capabilities. Monitor SAM.gov for any further updates.
Who this opportunity suits
This RFI is suitable for firms with expertise in space vehicle development, integration, and operations, ground segment development for satellite constellations, or digital engineering integration, especially within a government context. The North American Industry Classification System (NAICS) code for this effort is 541715, Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology), with a small business size standard of 1,000 employees.
The government encourages participation from small and small disadvantaged businesses. Companies must be in good standing on SAM.gov. Access to controlled unclassified information (CUI) and classified information requires specific clearances, with at least a Secret facility clearance needed for classified documents.
How to respond
To receive the full RFI and supporting documents, you must first contact the government points of contact via email. Send an email with the subject line “MEO Epochs 3 & 4 RFI – (company name)” to the government POCs. Include your company's name, mailing address, CAGE Code, Unique Entity Identification (UEI), point of contact (name, phone, email), and whether you plan to be a prime or sub-contractor.
CUI will only be sent to POCs listed in SAM.gov. For classified information, include a SIPR, JWICS, or comparable email address in your initial contact. Your organization must possess at least a SECRET facility clearance, which will be verified. The government is also willing to physically distribute content if electronic classified means are not available.
Practical tips for preparing a competitive response
Even though this is an RFI, a thoughtful and detailed response can position your company favorably for future opportunities. Clearly articulate your capabilities in relation to the specific elements requested: Epochs 3 & 4 Space Vehicles, MEO Ground segment, or Digital Engineering Integration.
Address the government's interest in Firm Fixed Price (FFP) contract types and Other Transaction Authority (OTA) agreements, providing feedback on this approach. If you are a small business, highlight your ability to meet the requirements and suggest ways to increase small business participation, including potential subcontracting opportunities. Ensure all required company information and clearances are up-to-date and accurately provided in your initial contact to facilitate access to the RFI documents.
