Description
Description — Initial Spares/Repair Parts
Program Description: Aircraft Initial Spares are required to fill the initial pipeline or inventory for all new aircraft systems, including modifications, support equipment, and other production categories. Initial spares include peculiar repairable and consumable components, assemblies, and sub-assemblies that must be available for issue at all levels of supply in time to support newly fielded end items. The following Major Defense Acquisition Programs (MDAP) have funding in this line: F-35,198 B-2, 431 FAB-T, 199 CV-22, 212 AWACS UPGRADE, 277 KC-46A, 387 MQ-9 UAS Reaper, 424 T-7A (APT), 436 F-15 EPAWSS, 485 HH-60W (CRH), 479 MH-139A, 562 Initial spares are funded in the two program segments described below. Working Capital Fund (WCF) Spares. Since FY 1994, some programs have used obligation authority in the WCF to procure initial spares. When the spares are delivered this central procurement account will reimburse the WCF. Types of spares in this program segment are Readiness Spares Packages, New Acquisition Spares, Modification Spares, Support Equipment, Other Production, and Consumables. Exempt Spares. This program segment finances spares that are not purchased through the WCF. The budget authority is a direct cite on the contract. Types of spares in this program segment are Whole Spare Engines, Whole Spare Quick Engine Change Kits, Contractor Logistics Support, Simulators/Trainers, New Acquisition Spares, Modification Spares, Support Equipment, Classified Equipment, and Munitions. The FY 2026 request for initial spares includes $973,535 thousand for discretionary and $1,023,806 thousand for mandatory (reconciliation) for a total of $1,997,341 thousand. The mandatory (reconciliation) funding supports initial spares for air vehicle propulsion, survivability, airframe and avionics programs. Further information for this reconciliation request is provided in Section 20007 (Air Superiority) and 20010 (Readiness) of the Reconciliation Exhibit. The FY 2026 funding request was reduced by a total of $28.222 million ($19.250 million for ATA000 and $8.972 million for E011A0) to account for the availability of prior year execution balances.

What it is
- Initial Spares/Repair Parts (budget line 000999) is a U.S. Air Force procurement line funded in the Aircraft Procurement, Air Force appropriation.
- Aircraft Initial Spares are required to fill the initial pipeline or inventory for all new aircraft systems, including modifications, support equipment, and other production categories, covering peculiar repairable and consumable components that must be available for issue at all levels of supply when newly fielded aircraft arrive.
- Funding runs through two segments: Working Capital Fund spares, where the central procurement account reimburses the Working Capital Fund on delivery, and Exempt Spares, financed as a direct cite on the contract and covering items such as whole spare engines, contractor logistics support, and simulators and trainers.
- Major Defense Acquisition Programs with funding in this line include the F-35, B-2, CV-22, KC-46A, MQ-9 Reaper, T-7A, F-15 EPAWSS, HH-60W, and MH-139A, among others.
- FY 2026 spares support specific modernization efforts across the fleet, including B-2 communications suites, B-52 radar and data-link modernization, C-5 viability, C-17 modification kits, C-130H avionics modernization, and E-4B airborne-command-center upgrades.
Why it matters
- The program's total funding is $1,997,341 thousand (about $2.0 billion) requested for FY 2026.
- In FY 2024 the program recorded actual spending of $865,790 thousand (about $866 million), so the FY 2026 request is more than double its recent execution level.
- The FY 2026 request splits into a discretionary request of $973,535 thousand (about $974 million) and a reconciliation (mandatory) request of $1,023,806 thousand (about $1.02 billion).
- The $1,023,806 thousand reconciliation (mandatory) portion is the larger half of the request and, combined with the discretionary base, produces the FY 2026 total.
- Per the program narrative, the mandatory funding supports initial spares for air-vehicle propulsion, survivability, airframe, and avionics programs, with further detail in Section 20007 (Air Superiority) and Section 20010 (Readiness) of the Reconciliation Exhibit.
Key players
- The program is run by the U.S. Air Force, with funding drawn from the Aircraft Procurement, Air Force appropriation.
- Because this is a pooled spares line rather than a single platform, it channels money to the parent Major Defense Acquisition Programs it supports — among them the F-35, B-2, KC-46A, MQ-9 Reaper, and T-7A — with two new-start efforts in FY 2026 for B-2 Squadrons and the MQ-9 UAV.
