E-3

The E-3 Modification Program is a line item within the Air Force's Aircraft Procurement budget, specifically targeting the modernization and sustainment of the E-3 Airborne Warning and Control System (AWACS) fleet. The program's goal is to ensure the continued viability of the E-3 platform as a critical asset for Battle Management Command and Control (BMC2), air surveillance, and threat warning. The fleet consists of 16 aircraft, and the program encompasses a range of capability improvements, reliability upgrades, and sustainment efforts to address aging systems and evolving operational requirements.

A major component of this line item is the effort to enhance the E-3's communication capabilities by integrating Second Generation Anti-Jam Tactical UHF Radio for NATO (SATURN) capability. This involves replacing legacy radios with newer models that support both existing and new military waveforms. The modification will be installed on 15 production aircraft, each receiving a four-radio configuration. The program transitioned from equipment procurement to installation and interim sustainment, reflecting the shift in funding priorities as the modification moves toward rapid fielding and operational capability.

Another significant objective is focused on improving the mission computing, sensor, and platform capabilities of the E-3 fleet. This upgrade addresses obsolescence issues and enhances the aircraft's ability to process and disseminate information in complex operational environments. These modifications are designed to ensure the E-3 remains interoperable with joint and coalition forces, supporting advanced battle management and airspace control missions.

Targeted upgrades are also aimed at bolstering the aircraft's networking and identification capabilities. Improvements in networking enhance the E-3's ability to connect with other platforms and command centers, while upgrades to identification systems ensure compliance with modern Identification Friend or Foe (IFF) standards. These efforts support secure and reliable identification in contested environments and are driven by the need to maintain operational relevance and meet Department of Defense mandates for secure communications and identification.

Additional modifications further support the E-3's role in integrated air defense and joint operations. Advanced identification technology is being implemented to distinguish friendly and adversary forces, while new capabilities enable the aircraft to participate in IP-based networks. These enhancements facilitate real-time data sharing and improved situational awareness, which are critical for maintaining the E-3's effectiveness in modern, network-centric warfare.

Reliability and maintainability upgrades such as improvements to the vertical stabilizer and rudder, as well as various low-cost modifications to airframe, avionics, communications, and human systems, are included to address Diminishing Manufacturing Sources (DMS) and extend the service life of the E-3 fleet. These efforts ensure the aircraft remain safe, reliable, and cost-effective to operate, reducing the risk of mission failure due to aging components or system obsolescence.

Funding is also provided for Air Education and Training Command to support field training detachments, ensuring that pilots, air battle managers, and maintainers are proficient in operating and sustaining the unique systems of the E-3. This training investment is essential for maintaining readiness and operational effectiveness. The E-3 Modification Program balances capability improvements with reliability upgrades and training support to meet current and future mission requirements.
