Other Support Aircraft

The Other Support Aircraft program, detailed in Line Item 0465 of the Department of the Navy's FY2026 Aircraft Procurement budget, focuses on acquiring operational support airlift (OSA) platforms, specifically the UC-12W aircraft for the U.S. Marine Corps (USMC). The program aims to modernize and expand the USMC's ability to transport high-priority passengers and cargo with time-sensitive requirements, replacing older UC-12F/M models with newer, more capable aircraft. This modernization effort is driven by the need to maintain reliable, flexible, and responsive airlift capabilities for both routine and mission-critical operations.

For FY2026, the program requests funding to procure one UC-12W aircraft, including associated airframe contractor-furnished equipment (CFE), government-furnished equipment (GFE), and support funding. The UC-12W is a Federal Aviation Administration (FAA) type-certified commercial cargo/passenger transport aircraft, tailored for military use with unique systems such as Ultra High Frequency (UHF) radio, Tactical Air Navigation (TACAN), Identification Friend or Foe/Selective Identification Feature (IFF/SIF), and Aircraft Survivability Equipment (ASE). These enhancements ensure the aircraft meets military operational requirements, including the ability to operate from short, unimproved airfields and carry at least nine passengers or light cargo.

The program's objectives also include the provision of initial spares, which are critical for ensuring aircraft readiness and minimizing downtime during the early operational period. The procurement strategy supports the USMC's increased Program of Record (POR) quantity, which was raised from 12 to 30 aircraft in July 2023 to address expanding operational requirements and ensure adequate coverage for both active and reserve components.

In prior years, the program procured seven UC-12W aircraft, with additional units acquired for the USMC Reserves using National Guard & Reserve Equipment Account (NGREA) funding. The procurement history demonstrates a phased approach to fleet modernization, balancing immediate operational needs with long-term planning. Textron Aviation Inc., located in Wichita, Kansas, is the designated manufacturer, with contract awards and delivery schedules structured to maintain a steady flow of new aircraft into the fleet.

The cost analysis for the program breaks down expenditures into recurring costs such as airframe and electronics, non-recurring costs including ancillary equipment, and support costs covering logistics, engineering, training, and ground support equipment. This comprehensive approach ensures that each aircraft delivered is fully mission-capable and supported throughout its lifecycle.

Production and delivery schedules are coordinated to align with operational requirements, with procurement lead times and manufacturing timelines managed to optimize fleet availability. The program's acquisition strategy emphasizes reliability, cost-effectiveness, and the ability to respond to evolving mission demands. By investing in the UC-12W platform, the Navy and Marine Corps aim to sustain and enhance their operational support airlift capabilities well into the future.
