Budget figures
$78.3M discretionary + $2.10M one-time reconciliation. Discretionary change vs FY2025 enacted: +39.3%.
Two official figures, one label— reconciled below
Fiscal Receipts uses P-1/R-1 workbook total obligation authority (TOA) as the headline figure sitewide. The workbook TOA includes budget rows that the R-2/P-40 J-book program line excludes — advance procurement in an ordinary year, and in FY2026 the one-time reconciliation appropriation as well. Each row below names the one it is. How the two bases relate →
FY26 Request · $80.4M TOA − $78.3M J-book line = 2.10M (80.4 − 78.3 = 2.1) — $2.10M of one-time FY2026 reconciliation money accounts for this gap — not advance procurement
Figures in the sentence are rounded for reading; the parenthesised arithmetic is the same subtraction in USD millions, at the precision where it closes.
FY2026 award data is a partial year — USAspending reports awards on a rolling basis, and this corpus runs through 2026-09-04. why partial FY2026 data? →

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.

blank = series not published for this year; – = absent from that edition.
Asked vs spent: the PB2021 book requested $159.8M for FY2021; the PB2023 book reported $79.9M as actual total obligation authority — $79.9M below the request. 79.9 − 159.8 = -79.9 USD millions — the compact figures above are rounded for reading.

Description
Mission — F-15EX
The F-15EX is a new multirole-capable fighter jet based on the 2-seat F-15QA (Qatar) configuration upgraded with advanced capabilities, including the Eagle Passive Active Warning Survivability System (EPAWSS) and the USAF F-15 Continuous Delivery & Integration (CD&I) Operational Flight Program (OFP) software. The F-15EX provides significant operational flexibility, enabling it to perform a wide range of missions sets with one or two aircrew. It will be used predominantly in defensive and offensive counter-air missions at both Air National Guard (ANG) and Air Combat Command (ACC) operational squadrons. F-15EX will perform the Homeland Defense mission and provide Combatant Commanders (CCDR) with strike packages capable of operating in Highly Contested Environments (HCE). The FY 2026 RDT&E funding request continues incremental funding of development activities started in prior years and adds funding for Long-Range Kill Chain (LRKC) and Hybrid SATCOM (Beyond Line-of-Sight communications) development, a FY 2026 new start. The FY 2026 request for the Research & Development appropriation for F-15EX includes $78,345 thousand of discretionary and $2,100 thousand of mandatory (reconciliation) for a total of $80,445 thousand. The mandatory funds will support LRKC efforts. Further information for this reconciliation request is Provided in Section 20007 (Air Superiority) of the Reconciliation Exhibit. The FY 2026 request was reduced by $0.811 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. This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program element 0605829F, 0605831F, 0605833F or 0605898F. In FY 2024, 9.536M was executed for civilian pay expenses in this program element. In FY 2025, 6.206M is forecasted for civilian pay expenses in this program element. In FY 2025, the F-15EX program reduced civilian personnel to 38 positions which aligned to the Executive Order 14210, "Implementing the President's Department of Government Efficiency Workforce Optimization Initiative.” The FY 2026 request was reduced by 2.132 million from FY 2024 as reflected in the Direct Cite Authority line in Exhibit R-3. FY 2020 Prior Years RDT&E funding of $385.000 million was executed in PE 0207134F (F-15E Squadrons) and is not included in this exhibit. FY 2020 RDT&E funded two F-15EX test aircraft. In FY 2021, F-15EX RDT&E efforts were continued in PE 0207146F (F-15EX). This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate production funding in the current or subsequent fiscal year.
Justification
Accomplishments & Planned Programs (2)
Hybrid SATCOM
Hybrid SATCOM is an F-15EX multi-band SATCOM solution that leverages terminal and aperture capabilities developed in Advanced Battle Management System (ABMS) PE 0604003F, eliminating duplication of effort and optimizing capability delivery in alignment with the DAF BATTLE NETWORK architecture.
F-15EX
F-15EX RDT&E funding continues ongoing capability development and test efforts, as well as integration of long-range kill chain (LRKC) weapons. LRKC development efforts provide the F-15EX responsive, long-range strike capabilities against time-critical or heavily defended targets and Offensive Counter-Air/Defensive Counter-Air (OCA/DCA) mission sets.

Oversight
GAO oversight of this program
GAO assessed F-15EX in its June 2025 Weapon Systems Annual Assessment, as an Air Force MDAP program.
“The Air Force's F-15EX program is intended to address F-15C/D readiness challenges and eventually replace the F-15C/D fleet. The program began as a middle tier of acquisition effort. The F-15EX, based on a current foreign military sales aircraft design, will be upgraded with capabilities unique to the U.S., including operational flight program software and Eagle Passive Active Warning and Survivability System (EPAWSS) upgrades. EPAWSS is assessed separately in this report. The F-15EX is planned to be a complementary platform to fifth-generation F-35 and F-22 stealth aircraft operating in highly contested environments.”

GAO assessed the program, not this budget line. F-15EX is one of the lines that funds it, and GAO’s work above says nothing about this line’s own figures. Which line each GAO item attaches to is a hand-ratified crosswalk — how it was checked.
Department-level designation (not specific to this program)
GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not F-15EX. GAO's program-level work on this line is above. See the DOD oversight record.
