With the aim of strengthening the technical sustainment of its combat fleet, the U.S. aerospace company Pratt & Whitney will remanufacture engine modules for the Chilean Air Force’s F-16 fighter jets, under an international contract aimed at maintaining the reliability and operational continuity of these aircraft. The initiative is part of a broader logistical support program under the Foreign Military Sales (FMS) framework, also covering multiple F-16 operator countries and consolidating a long-term maintenance strategy.
The agreement, awarded to Pratt & Whitney, provides for an estimated amount of 470 million dollars corresponding to a global sum intended for the full set of countries participating in the program. The contract calls for the remanufacture of F100 engine modules, essential for the propulsion of the F-16, and was processed as a sole-source acquisition in accordance with current U.S. regulations. Its execution will take place primarily in the state of Georgia, with an expected completion date of March 2029, also including extension options that could prolong its duration.
This program involves a broad portfolio of international users within the FMS system, including Chile alongside countries such as Egypt, Greece, Indonesia, Iraq, Morocco, Pakistan, Poland, Romania, Saudi Arabia, Thailand, Taiwan, and Jordan. Contract management falls under the Defense Logistics Agency Weapons Support, based at Hill Air Force Base, Utah, and will be funded through appropriations corresponding to fiscal years 2026 through 2029.
The award to Pratt & Whitney comes in parallel with the recent contract granted to BAE Systems for the support and maintenance of the Chilean Air Force’s F-16 fleet, valued at 98.8 million dollars. This global agreement includes engineering services and assistance related to electronic and diagnostic systems, ensuring the operability of the avionics and extending its time horizon through 2037. Taken together, both initiatives reflect a comprehensive approach that covers both the airframe and the aircraft’s critical systems.
In this context, the Chilean Air Force is also moving forward with the modernization of its F-16 Block MLU aircraft through a contract signed with Lockheed Martin in 2023 to upgrade them to the “Tape M 6.6” standard. This process includes substantial improvements in radar, communications, avionics, and weaponry, with work to be carried out both in the United States and in Chile, and an estimated completion horizon toward 2032. The possible incorporation of advanced technologies, such as active electronically scanned array radars, could position these fighters among the most capable in the region.
Two decades after their incorporation, the F-16s continue to serve as the core of Chile’s air defense system, operating as part of a networked combat architecture alongside early warning and aerial refueling platforms. The combination of support, modernization, and critical component remanufacturing contracts reflects a sustained policy aimed at preserving the fleet’s technological relevance and operational availability, guaranteeing its performance in an increasingly demanding strategic environment.
