VC-25A Mod

The VC-25A Mod program is focused on modernizing two VC-25A aircraft, known as "Air Force One," which are essential for presidential support. These aircraft, originally purchased in 1987 and delivered in 1990, are undergoing modifications to extend their service life until the newer VC-25B aircraft become operational. The primary objectives include enhancing communication capabilities and addressing technological obsolescence. This involves implementing low latency worldwide data connections, aggregated throughput bandwidth, and a Multi-Role Tactical Common Data Link (MR-TCDL), among other upgrades.

The Air Force has identified these modifications as crucial for national security interests, ensuring that the aircraft remain capable of fulfilling their presidential mission requirements. The program also aims to maintain compliance with Federal Aviation Administration (FAA) airworthiness standards through necessary service bulletins and modifications. Additionally, efforts are being made to mitigate issues related to diminishing manufacturing sources and material shortages, ensuring the continued reliability and maintainability of these aircraft.

The VC-25 Block Upgrade is a significant component of this modernization effort. It includes the integration of advanced communication systems such as low earth orbital satellite communications to minimize latency during global communications. This upgrade also enhances the onboard infrastructure to support increased bandwidth demands. The MR-TCDL installation allows seamless communication between airborne platforms and ground entry points, further improving the aircraft's operational capabilities.

Boeing, located in San Antonio, Texas, is responsible for implementing these modifications at their contractor facility. The upgrades are scheduled to align with the aircraft's heavy maintenance cycles to minimize downtime. This comprehensive modernization initiative ensures that the VC-25A aircraft continue to meet evolving mission requirements while supporting a full financial audit as mandated by U.S. law.
