KC-46A MDAP

The KC-46A MDAP program is a Major Defense Acquisition Program managed by the U.S. Air Force under the Aircraft Procurement, Air Force appropriation. Its primary objective is to recapitalize the aging fleet of aerial refueling aircraft, replacing legacy tankers in several stages. The KC-46A is intended to provide approximately one-third of the current refueling capability in its initial increment, with future programs planned to eventually replace the entire tanker fleet over a span of more than 30 years.

The program was initiated following a comprehensive Analysis of Alternatives (AoA) in 2006, which determined that a commercial derivative replacement selected through full and open competition would offer the best value for the Air Force's requirements.

For Fiscal Year 2026, the KC-46A MDAP budget line supports the procurement of additional aircraft, continuing the production of one lot and preparing for the next. This includes funding for Government Furnished Equipment, such as Large Aircraft Infrared Countermeasures, and the procurement of low-technical risk components like Boom Telescope Actuator kits to address Category I deficiencies. The program also funds support equipment, operational site activation, depot stand-up, interim contractor support, alternate mission equipment, and direct mission support. These elements are critical for ensuring the delivery, sustainment, and operational readiness of the KC-46A fleet.

The Aircrew Training System and Maintenance Training System are essential components funded within the KC-46A MDAP line. The aircrew training contract provides training devices such as Weapon System Trainers, Boom Operator Trainers, and Fuselage Trainers, supporting validated Air Mobility Command training requirements at Main Operating Bases and the Formal Training Unit. The maintenance training contract focuses on developing and fielding a blended training solution for KC-46 maintainers, integrating hardware, software, and emerging technologies to meet maintenance training needs. These training systems ensure that both aircrew and maintainers are proficient in operating and sustaining the KC-46A fleet.

The Depot Stand-Up initiative is another significant objective within the KC-46A MDAP budget. The designated depot source of repair is responsible for aircraft maintenance checks, software maintenance, engine maintenance, and commodities maintenance. Funding supports the transition to organic sustainment, procurement of depot support equipment, initial operating equipment, and the establishment of the Government Software Integration Lab for organic software sustainment. These efforts are timed to align with aircraft deliveries and are necessary to ensure long-term, cost-effective maintenance and operational support for the KC-46A fleet.

The KC-46A program also addresses several technical and operational requirements, including the integration of advanced communication, navigation, and surveillance equipment for worldwide operations. The aircraft is designed to operate in chemical and biological environments and up to medium threat environments with self-defense capabilities. The program includes funding for studies and analyses related to efficiency initiatives, diminishing manufacturing sources, and obsolescence planning, ensuring the fleet remains viable and effective throughout its lifecycle.

Additionally, the KC-46A MDAP supports Mobility Air Forces connectivity efforts, which require Line-of-Sight and Beyond-Line-of-Sight connectivity capabilities. This is achieved through the integration of multi-band, multi-orbit SATCOM terminals, enabling real-time secure command and control and enhancing situational awareness for aircrews. The KC-46A is also planned to serve as a key joint and coalition communications node, supporting joint and coalition receivers via boom or drogue systems and augmenting the airlift fleet with cargo, passenger, and aeromedical evacuation capabilities.
