Description
Description — C-17A
The four-engine C-17 is the only aircraft capable of routine delivery of outsize cargo (tanks, helicopters, etc.) to short, austere airfields. The USAF operates a fleet of 222 C-17 Globemaster III aircraft. The aircraft were delivered to the USAF from 1995-2015, the fleet is planned to be in operational until 2050. The aircraft can carry up to 102 troops, 36 litter patients or 18 standard 463-L pallets. The C-17 can perform the entire spectrum of airlift missions and is specifically designed to operate effectively and efficiently in both strategic and theater environments. Not only can the C-17 deliver outsize cargo to austere tactical environments, but it also reduces ground time during air and land operations. Strategic Airlift provides essential flexibility when responding to contingencies on short notice anywhere in the world. It is a major element of America's national security strategy and constitutes the most responsive means of meeting mobility requirements. Specific tasks associated with the airlift mission include deployment, employment, sustaining support, retrograde, aeromedical evacuation, and combat redeployment. The C-17 will perform this airlift mission well into this century. This funding includes Rapid Global Mobility (RGM) platform-related rapid prototyping and fielding activities executed under the authority of the National Defense Authorization Act 2016, Section 804, as amended. Such activities include, but are not limited to, roll-on/roll-off, carry-on/carry-off, and pod-based aircraft integrated support equipment, as well as other technical solutions supporting the full spectrum of the platform's RGM mission. Filter Fire Mitigation redesigns the On-Board Inert Gas Generation System (OBIGGS) II Shutoff Valve to a failsafe closed condition, thus eliminating a safety-of-flight issue. Funding may also be used to address Diminishing Manufacturing Sources (DMS) issues, obsolescence resolution, fuel efficiency and drag reduction improvements, cockpit situational awareness, command and control (radios), flight deck modernization/replacement, aircraft data bus maintenance initiatives, and structural enhancements. In accordance with Section 1815 of the FY08 National Defense Authorization Act (P.L.110-181), these items are necessary for use by the active and reserve components of the Armed Forces for homeland defense missions, domestic emergency responses and providing military support to civil authorities. Funding for this exhibit is contained in PE 0401130F and 0401897F. The FY 2026 request was reduced by $0.556 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative."
Description — C-17A
This effort supports Post Production support efforts for the C-17. These funds are required to effectively perform aircraft maintenance at Organizational and Intermediate (O&I) levels of aircraft maintenance at Main Operating Bases (MOBs), Avionics Regional Maintenance Centers (RMCs), Engine RMCs, Enroute locations, Backshop activities, plus requirements in support of the Analytical Condition Inspections. The areas of focus include, but are not limited to: - The Engine Depot Stock & Preservation Kit buy provides investment-funded engine depot replenishment spares to support depot operations. - Purchase of Peculiar and Common Support Equipment for the C-17 (PSE and CSE). CSE is comprised of support equipment used by the C-17 and other programs, while PSE is unique to the C-17. Both are required to effectively perform aircraft maintenance at Organizational and Intermediate (O&I) levels of aircraft maintenance at Main Operating Bases (MOBs), Avionics Regional Maintenance Centers (RMCs), Engine RMCs, Enroute locations, Backshop activities, plus requirements in support of the Analytical Condition Inspections - Materiel Improvement Program (MIP) projects. MIP projects correct Deficiency Report (DR) issues that were discovered during the aircraft production phase. There have been over 275 projects incorporated into production aircraft. Approximately 3 projects remain to be retrofitted to post production aircraft to bring them up to production aircraft configuration. The remaining projects are TCTO -1695 (7 installations), TCTO -2031 (107 installations) and TCTO-2133 (87 installations), equating to a 201 total USAF installations. The projects are worked in conjunction with aircraft heavy maintenance (depot) cycle every 6 years. This modification supports performance of a full financial audit as required by title 10 U.S.C. Chapter 9A, Sec 240-D. Funding may be used to address Diminishing Manufacturing Sources (DMS) issues. Funding for this exhibit is contained in PE 0401130F.

Justification — C-17A
This program, Category Uncategorized Item Material Improvement Program (MIP), is a new start. This program, Category Uncategorized Item Engine Depot Stock and Preservation Kit Buy, is a new start. This program, Category Uncategorized Item Peculiar Ground Support Equipment (PSE), is a new start. In FY 2026, 2.372M of this funding will be primarily used on Material Improvement Program (MIP) installation labor to ensure the previous DRs are corrected during aircraft heavy maintenance. The remaining 0.3M will be used toward engine depot stock and PSE procurement.
