C-130

The C-130 Modification Program (Line Item C13000) in the FY 2026 Air Force budget is focused on sustaining and modernizing the Air Force's fleet of C-130H and Special Mission C-130 aircraft. The primary objective is to ensure these aircraft remain operationally viable, safe, and effective for both current and future mission requirements. This line item supports a range of modifications and upgrades, including avionics modernization, structural life extension, propulsion improvements, and low-cost safety enhancements. Funding is distributed across the Air Force, Air National Guard, and Air Force Reserve.

C-130H Avionics Modernization Program (AMP) Increment 2 is a major component of this line item, with the goal of replacing aging and unreliable cockpit and avionics systems. AMP Increment 2 addresses obsolescence and Diminishing Manufacturing Source (DMS) issues, enhances combat capability, and implements a modular, cyber-resilient open systems architecture. The program also includes upgrades to training systems and simulators, and integrates secure, anti-jam communications to maintain interoperability with Department of Defense, NATO, and coalition partners. The program will procure modification kits for installation in Air National Guard and Reserve aircraft, with installation scheduled for future fiscal years.

C-130 Systems/Structure (Phase II Modernization) focuses on the replacement of Center Wing Boxes (CWB) on C-130H aircraft. The objective is to extend the service life of these aircraft by replacing the original CWBs, which are limited to a set number of equivalent flight hours, with Extended Service Life (ESL) CWBs rated for a significantly higher number of hours. This effort is essential to maintain the viability of the aging C-130H fleet, which will remain in service for decades. Funding is allocated for the procurement and installation of CWB kits, with installations planned at the Warner Robins Air Logistics Complex.

C-130 8-Bladed Propeller Upgrade (NP2000) is another key modification, aimed at improving aircraft performance, reliability, and maintainability. The NP2000 propeller system reduces vibration, enhances fuel efficiency, and lowers maintenance costs. Installations were completed on a substantial number of C-130H aircraft, and funding supports interim contractor support to sustain this modification.

Low Cost Modifications and Safety Upgrades are included to address emerging operational needs and safety concerns. These efforts encompass a variety of smaller projects, such as crashworthy loadmaster seats, auxiliary hydraulic pumps, radar warning receivers, and onboard fire incident response equipment. The goal is to incrementally improve safety, survivability, and mission effectiveness at a relatively low cost, while also addressing reliability and maintainability issues as they arise.

Program Justification and Compliance is rooted in statutory requirements and operational necessity. The C-130 modification program is mandated by Section 1815 of the FY 2008 National Defense Authorization Act, which requires the Air Force to maintain a viable C-130 fleet for homeland defense, emergency response, and military support to civil authorities. The program also aligns with Executive Order 14222, which emphasizes government efficiency and cost control. Funding may be used to address DMS issues and to ensure continued support for both active and reserve components.
