Air Force Issues RFI for F-15EX Missile Warning System Development

On September 29, 2026, the U.S. Air Force made a strategic move by issuing a request for information (RFI) for a new missile-warning system (MWS) designed specifically for the F-15EX Eagle II fighter jet. This initiative seeks to bolster the aircraft’s defensive posture against infrared-guided missile threats, a crucial enhancement given the operational environment in which advanced fighter jets operate today. The Air Force’s decision to pursue an RFI instead of a conventional Request for Proposal (RFP) underscores the preliminary nature of this procurement effort, which invites industry feedback regarding capabilities, technology integration, and potential solutions to fill existing gaps in F-15EX’s defensive suite.

The urgency for an effective missile warning system comes from the F-15EX's current configuration, which lacks the BAE Systems AAR-57 Common Missile Warning System found on comparable platforms. While the F-15EX is equipped with the BAE Enhanced Passive/Active Warning Survivability System targeted at radar-guided threats, it does not yet possess a dedicated solution for detecting incoming missiles utilizing their thermal signatures. This gap presents inherent risks for pilots operating in contested environments where missile threats are increasingly prevalent. The RFI aims to solicit insights from contractors that can offer potential technologies compatible with the aircraft’s pre-existing sensor locations.

Notably, the Air Force is looking for systems that can integrate with the F-15EX's six established sensor points – situated in the tail, on the cockpit canopy rim, and on the aircraft's belly – while effectively minimizing false alarms that could significantly distract pilots during critical missions. According to the details provided in the RFI, the emphasis is placed on a system that must “alert the F-15EX aircrew to missile threats without unreasonably distracting the aircrew with false alarms.” This requirement highlights the complexity and challenges involved in designing modern avionics that balance responsiveness with pilot workload management.

Historically, the Air Force's requirements for missile warning systems have evolved significantly. Previously, the service collaborated with the U.S. Army and the U.S. Navy in developing missile warning technologies but later withdrew from joint programs, favoring tailored solutions for its portfolio of fourth-generation fighters. Notably, the Lockheed Martin F-35 comes equipped with an AAQ-37 electro-optical distributed aperture system that provides similar missile detection capabilities, while the Lockheed F-22 employs the AAR-56 missile launch detector system. The Air Force's focus now on the F-15EX aims to close technological gaps and ensure that the aircraft remains capable in modern warfare scenarios.

The implications of this RFI extend beyond mere technology adoption; it signals a realization by the Air Force of the evolving threats faced by aircrews and the necessity for advanced defensive measures. Contractors engaged in this space should be proactive in assessing their missile-warning technologies, identifying potential synergies with the F-15EX’s design, and preparing to submit relevant feedback on the requirements outlined by the Air Force.

Key industry stakeholders should note that while this initiative represents a significant opportunity to influence future procurements, the absence of a specified budget or deadline indicates that this process is primarily an exploration phase devoid of immediate procurement implications. As such, firms should perceive this RFI as a platform for market research and capability shaping rather than a traditional solicitation targeting immediate monetary awards. Establishing strong communication lines with the Air Force and showcasing relevant technical capabilities could potentially place contractors in advantageous positions in future competitive bids.

• The U.S. Air Force is seeking innovative solutions for missile warning systems compatible with the F-15EX.
• The MWS must be able to reduce false alarms to ensure pilot focus during engagements.
• Contractors can provide inputs to shape future requirements without a submission deadline present.
• No budget or funding has been identified, indicating a preliminary research phase for procurement.
• The RFI invites technology assessment specific to the F-15EX’s existing sensor integration.
• Companies should align their capabilities with historically unsuccessful defense collaborations to highlight innovations.
• The request highlights a trend toward enhancing situational awareness in multi-threat environments.
• Effective missile warning systems are crucial for survivability during combat missions involving the F-15EX.
