What it is

F-35 (budget line ATA000) is a U.S. Air Force procurement line funded in the Aircraft Procurement, Air Force account. The line procures the F-35 Joint Strike Fighter, a family of aircraft with three variants — the F-35A conventional takeoff and landing, the F-35B short takeoff and vertical landing, and the F-35C carrier variant — sharing maximum commonality to minimize life-cycle cost.

5 fiscal years of this program as published (FY2022–FY2026): a line through the actuals (filled dots), with the enacted (hollow circles) and request (diamonds) markers each edition reported. Read it for direction, not for precision — this program's actuals line rises across the span. The grid below is the same data as text, one cited figure per cell.

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.

● actuals (line) · ○ enacted · ◇ request — gaps are editions the program is absent from, never interpolated.

Decade series values by fiscal year and President's Budget edition: one row per series (actuals, enacted, request), one column per fiscal year. Every figure opens its own citation.

blank = series not published for this year; – = absent from that edition.

Asked vs spent: the PB2024 book requested $5.28B for FY2024; the PB2026 book reported $5.57B as actual total obligation authority — $286.5M above the request. 5,565.655 − 5,279.121 = 286.534 USD millions — the compact figures above are rounded for reading.

Description

Description — F-35

Joint Strike Fighter (JSF) program will enhance and field a family of aircraft that meets the needs of DoD and allies with three air vehicle variants including: the F-35A Conventional Take Off and Landing (CTOL) variant, the F-35B Short Take-Off and Vertical Landing (STOVL) variant, and the F-35C Carrier Variant (CV) delivering commonality among the three variants to minimize life cycle costs. This is a joint program with no executive service. Service Acquisition Executive (SAE) authority alternates between the Department of the Navy (DoN) and the Department of the Air Force (DAF) and currently resides with the Navy. The F-35 is the next generation of strike fighters and provides increased aero-performance, stealth signature, and countermeasures. Its advanced avionics, data links, and adverse weather precision targeting incorporates the latest technology available. The F-35 has increased range with internal fuel and can employ superior weaponry over existing aircraft. The highly supportable, affordable, state of the art aircraft commands and maintains global air superiority. The production cost and quantities are interdependent due to sole source air vehicle and propulsion contracts. United States Air Force (USAF) regular procurement commenced in FY 2007, DoN regular procurement commenced in FY 2008. Funding for this exhibit contained in PE 0207142F. Notes: USAF Initial Operational Capability (IOC) occurred on 2 August 2016 and the Full Rate Production (FRP) occurred on 12 March 2024.

Justification

Justification — F-35

The FY 2026 budget provides funding for 24 F-35A Aircraft, Engines and associated Non-Recurring and ancillary mission equipment to support production and delivery. The budget request supports aircraft procurement and support requirements for squadron standup and associated training and logistical efforts. Non-Recurring flyaway costs for FY 2026 include costs for tooling required to support full production capacity for hardware associated with delivering Block 4 capabilities. Non-Recurring costs also include funding to address Diminishing Manufacturing Sources (DMS) which includes costs to manage DMS issues, procurement of bridge or life-of-type buys, and if cost-benefit analysis supports Non-Recurring engineering to implement DMS redesigns within the performance envelope to the production line. Other non-recurring costs include but are not limited to chase support for government acceptance flights, Engineering Change Proposal Integration Contracts, systems engineering for production line efforts and production readiness reviews to address program risks and cost reduction initiatives. Support costs in FY 2026 include costs that are fixed in nature and costs that fluctuate based on squadron/site stand up requirements. Support cost supports the procurement of airframe, engine, and avionics peculiar ground support equipment (PGSE) to support squadron and site stand-ups. These include the procurement of airframe, engine, and avionics peculiar ground support equipment (PGSE), as well as training equipment to support squadron and site stand-ups. The program will continue implementing the strategy to transition from the Autonomic Logistics Information System (ALIS) to the F-35 Operational Data Integrated Network (ODIN), a modern F-35 logistics information system. Hardware being procured is compatible with both ALIS and ODIN software. Depot activation efforts continue in FY 2026, increasing repair capacity necessary for long-term sustainment of F-35 aircraft. FY 2026 request includes equipment and material to support establishment of depot repair capability, capacity and cyber compliance for components/sub-components across all U.S. Depots, support equipment for air vehicle modification dock expansion and Block 4 depot repair capability. FY 2026 includes funding for propulsion depot standup to include module repair activities to meet expanding fleet repair requirements. The FY 2026 request was reduced by -$.851 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.

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.
