The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Asked vs spent: the PB2024 book requested $140.6M for FY2024; the PB2026 book reported $120.7M as actual total obligation authority — $19.9M below the request. 120.71 − 140.56 = -19.85 USD millions — the compact figures above are rounded for reading.

Description
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.
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."
Justification
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.

Follow the dollar
No follow-the-dollar view — this program's awards haven't been crosswalked at high confidence (flows cover 312 of 1,938 programs). why coverage is partial? →
Related awards
Award linkage is shown for 32 of 200 profiled companies — high- and medium-confidence USAspending matches, each row labeled; medium is the weaker evidence. why partial award coverage? →
Rows marked medium rest on evidence weaker than a program-level match, and of more than one kind. An account-based row, where the award drew from the same appropriation account as this program, is an association, not evidence that this program paid for the contract. Where the evidence is instead an FPDS acquisition-program tag or a subaward description, the program is established but which of its budget lines paid is not. An announcement link a recorded review did not leave standing is medium too. Only high rows rest on the contract naming this program with a recorded review upholding it and no recorded rejection or refutation applying.
| Recipient | PIID | Confidence |

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
Lobbying mentions
