F-15E Squadrons

The F-15E Squadrons Program (PE 0207134F) is a key Air Force initiative under Budget Activity 7, Operational Systems Development, focused on the research, development, test, and evaluation (RDT&E) of upgrades and modernization for the F-15E aircraft fleet. The program's overarching goal is to ensure the F-15E remains a viable and effective platform for air superiority and deep-penetration strike missions well into the future, supporting the National Defense Strategy (NDS). With newer F-15E aircraft expected to serve beyond 2040, this program emphasizes avionics modernization, electronic warfare enhancements, and integration of advanced weapons and sensors to maintain lethality, survivability, and supportability against evolving threats.

F-15 Modernization (Project 676020) is the primary line item within this program element, encompassing a suite of development efforts to upgrade the F-15C, F-15D, F-15E, and F-15EX aircraft. Objectives include electronic protection and electronic attack improvements, advanced radar capabilities, threat mitigation, nuclear mission certification, and integration of new and upgraded weapons. Modernization activities are closely aligned with Air Combat Command priorities and are designed to complement fifth-generation aircraft by providing substantial capacity for long-range fires, sensors, and electronic warfare capabilities. The program also addresses emerging safety of flight issues, technology insertion, and compliance with federal mandates, such as those from the Federal Aviation Administration and National Security Agency.

Operational Flight Program (OFP) Development Efforts are central to the F-15 modernization strategy. The OFP provides ongoing software and hardware updates necessary to integrate new capabilities, including the Infrared Search and Track system, Eagle Passive Active Warning and Survivability System, and advanced radar and sensor technologies. In 2023, the OFP transitioned to a Continuous Development and Integration approach, enabling annual software releases through agile development techniques. This framework allows for rapid adaptation to emerging threats and ensures that the F-15 fleet maintains a competitive edge. Funding supports capability integration and the development of public-private partnerships for avionics software development.

Flight Test funding supports the modernization and sustainment of test capabilities, including infrastructure and personnel for developmental and operational test operations at Eglin and Nellis Air Force Bases. Objectives include upgrading test jets to meet requirements, replacing obsolete instrumentation, modernizing labs, and supporting the weapons and Long-Range Kill Chain roadmaps. These activities ensure robust integration and testing of new capabilities across the F-15 test enterprise, maintaining readiness and reliability for fleet-wide upgrades.

F-15 Radar Enhancements focus on improving radar capabilities through technical studies and the development of future enhancements. The program aims to implement electronic protection and electronic attack features into operational flight programs, improve interoperability, and conduct risk reduction activities for future integration. These efforts are critical to maintaining radar superiority over current and emerging threats, and funding increases reflect the need for continued evolution of warfighting capabilities and program protection elements.

GPS M-Code / Resilient-Embedded GPS Inertial Navigation System is managed by the Air Force's PNT program office and is designed to provide enhanced Position, Navigation, and Timing capabilities with improved resistance to jamming and spoofing. The program leverages open system architecture for modularity and adaptability, with funding supporting integration, software development, and testing specific to the F-15E and F-15EX platforms. This capability is essential for ensuring navigation reliability in contested environments.

Eagle Tether is a new start in FY 2026, aiming to deliver a single constellation satellite communications solution for the F-15E and EX. The program leverages technology from the Advanced Battle Management System and aligns with the Department of the Air Force Battle Network architecture to enable Long-Range Kill Chain capabilities. Objectives include developing and integrating SATCOM apertures and terminals, modifying aircraft software for open architecture implementation, and conducting comprehensive test and evaluation activities. This initiative is intended to enhance long-range communications and data sharing, supporting future operational requirements.
