How to bid on Foundation Sustainment Support, Software and Integration (FS3i) for NGA

What NGA is buying and why it matters

The National Geospatial-intelligence Agency (NGA) is seeking custom computer programming services for its Foundation Sustainment Support, Software and Integration (FS3i) program. This is an opportunity for vendors to provide specialized software development and integration support to a key government agency.

NGA has released a Bidder's Library to help potential vendors prepare. This library contains draft documents, questions and answers from previous engagements, and slides from an Industry Day event. This early access allows firms to understand the scope and requirements before the official Request for Proposal (RFP) is published.

Key dates and what happens at the deadline

This is a Request for Information (RFI) published on April 16, 2026. The deadline for this RFI is September 30, 2026, at 9:00 AM ET. At this time, no questions are being requested, and the purpose of this notice is to provide access to the Bidder's Library.

The official Request for Proposal (RFP) with full details and submission requirements will be published in the coming months. The deadline for the RFI is for accessing the provided preparatory materials, not for submitting a proposal.

Who this opportunity suits

This opportunity is suitable for firms specializing in technology, particularly those with expertise in custom computer programming, software development, and system integration. Companies with experience in geospatial intelligence or defense-related projects may find this particularly relevant.

Vendors who can provide sustainment support for complex software systems and integrate new solutions into existing infrastructures are well-suited for this program.

How to access the Bidder's Library

To access the Bidder's Library and other documents, you will need to go to the original source of the opportunity on the portal. If the first click takes you to the portal's homepage, click the link again to navigate directly to the bid.

You may need to create a free account on the portal to view the documents, though for some bids, an account is not required.

Practical tips for preparing a competitive response

Since this is an RFI with a Bidder's Library, focus on thoroughly reviewing all provided documents, including Industry Day slides and draft Q&As. This will give you a strong understanding of NGA's needs and expectations before the official RFP is released.

Begin to assess your firm's capabilities against the anticipated requirements. Identify any gaps or areas where you might need to partner with other businesses. Pay close attention to any recurring themes or specific technologies mentioned in the draft documents, as these are likely to be critical components of the final RFP.

Even though questions are not being requested now, formulate potential questions as you review the materials. This practice will help you be ready to submit inquiries once the official RFP is published and questions are permitted.
