How to bid on Integrated Air and Missile Defense Ground Systems Maintenance for DEPT of Defense

What the agency is buying

The Department of Defense is seeking engineering support for the Integrated Air and Missile Defense (IAMD) Battle Command System (IBCS) PATRIOT Advanced Capability-3 (PAC-3) Ground Systems Maintenance and Optimization (GSM&O) II. This work involves maintaining and optimizing IBCS Fire Control, IBCS Launcher Integrated Network Kit, and IBCS Enhanced Launcher Electronics System software.

This is a Request for Information (RFI) to identify potential sources for this effort. The government has identified Lockheed Martin Missiles and Fire Control as a proposed sole-source contractor due to their unique knowledge, expertise, and technical data package, as well as the government's lack of necessary intellectual property rights for full competition.

Key dates and deadlines

This Request for Information was published on September 08, 2026. Responses are due by September 23, 2026, at 5:30 PM ET. It is important to submit your response before this deadline.

Who this opportunity suits

This opportunity is for firms with specialized capabilities in maintaining and optimizing complex defense software systems, specifically related to the IBCS Fire Control, Launcher Integrated Network Kit, and Enhanced Launcher Electronics System for the PATRIOT PAC-3 ground system. The government has indicated a preference for Lockheed Martin Missiles and Fire Control due to their proprietary technical data and intellectual property rights. However, other firms with relevant expertise and a strong understanding of these specific systems may choose to respond to demonstrate their capabilities.

Tips for a competitive response

When responding to an RFI, clearly articulate your firm's specific capabilities and experience that directly relate to the requirements. Since the government has identified a proposed sole source, your response should highlight any unique qualifications, technical data, or intellectual property your company possesses that could enable you to perform this work. Provide concrete examples of past projects that demonstrate your expertise in maintaining and optimizing similar complex defense software systems.

Even if a sole source is proposed, a well-crafted RFI response can help the agency understand the broader market capabilities. Focus on demonstrating your firm's ability to meet or exceed the stated requirements, and if applicable, how your approach could offer advantages in terms of cost, schedule, or technical performance.
