KC-46A MDAP

The KC046A - KC-46A MDAP program, as detailed in the FY 2026 Air Force budget justification, is focused on the modification and modernization of the KC-46A Pegasus aerial refueling aircraft. The primary goal of this line item is to ensure the KC-46A remains a critical force extender for joint warfighting, supporting both air refueling and multi-role operations such as cargo, passenger transport, and aeromedical evacuation.

The program is managed under Aircraft Procurement, Air Force, specifically for the modification of in-service tactical aircraft. It is designed to address evolving operational requirements, regulatory directives, and deficiency corrections. Objectives include maintaining and enhancing the aircraft's capability to operate in diverse environments, including day/night and adverse weather conditions, and in chemical, biological, and medium-threat environments.

To achieve these objectives, the program funds a range of post-production modifications, including updates to avionics, structural systems, mission equipment, and self-defense features. These upgrades are driven by Mobility Air Force requirements, Combatant Commander Joint or Urgent Operational Needs, Federal Aviation Administration directives, and deficiency reports. The program also supports studies, analyses, and sustainment activities to ensure continued mission effectiveness and survivability.

One of the key budgeted modifications is the Pegasus Advanced Communications Suite (PACS), a new start initiative in FY 2026. PACS aims to upgrade the KC-46A's legacy communications systems, including Tactical Data Link 16 and UHF Line-of-Sight capabilities, with next-generation Link 16 terminals and secure, global, anti-jam satellite voice communications. This enhancement is designed to meet Department of Defense, National Security Agency, Department of Transportation, and U.S. Air Force mandates, ensuring interoperability with joint and allied forces and improving survivability in contested environments. The FY 2026 request includes procurement of PACS installation kits, assembled using Government Furnished Equipment such as the Multifunctional Information Distribution System - Joint Tactical Radio System.

Another significant objective is the modification focused on providing Line-of-Sight and Beyond-Line-of-Sight connectivity through integration of multi-band, multi-orbit SATCOM terminals. This upgrade will allow KC-46A aircraft to switch between satellite constellations, supporting higher data rates and enhanced command and control capabilities. The improved connectivity is essential for real-time secure communications and situational awareness, particularly in near-peer conflict scenarios where resilient and reliable data links are critical for mission success.

The program also includes funding for Reliability & Maintainability Safety Mods, Airworthiness Directives, and Low Cost Modifications. Reliability & Maintainability Safety Mods are aimed at improving the safety and reliability of the KC-46A fleet, addressing issues identified through operational use and deficiency reports. Airworthiness Directives support service life extension and compliance with regulatory requirements, while Low Cost Modifications provide incremental capability improvements that can be rapidly fielded to address urgent needs or emerging threats.

In addition to technical upgrades, the KC046A line item supports financial audit compliance as required by Title 10 U.S.C. Chapter 9A, Sec 240-D, and addresses Diminishing Manufacturing Sources issues to ensure long-term sustainment of critical components. The FY 2026 request also reflects a reduction for Advisory and Assistance Services, in alignment with Executive Order 14222 on government efficiency and cost savings. Funding is distributed across the Air Force, Air National Guard, and Air Force Reserve, reflecting the broad operational footprint of the KC-46A fleet.
