Budget figures
$448.1M discretionary + $50.0M one-time reconciliation. Discretionary change vs FY2025 enacted: +67.6%.
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 · $498.1M TOA − $448.1M J-book line = 50.0M (498.1 − 448.1 = 50.0) — $50.0M 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.

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.

Asked vs spent: the PB2024 book requested $297.3M for FY2024; the PB2026 book reported $250.5M as actual total obligation authority — $46.8M below the request. 250.5 − 297.3 = -46.8 USD millions — the compact figures above are rounded for reading.

Description
Description — F-16 Modifications
The F-16 is a multi-role fighter that comprises roughly 40% of the USAF fighter fleet with over 830 aircraft supporting a variety of air-to-air and air-to-surface missions, such as offensive and defensive counter-air, close air support, forward air control, air interdiction (day/night and all-weather) and Suppression of Enemy Air Defenses (SEAD)/Destruction of Enemy Air Defenses (DEAD). F-16 posture and readiness combined with low operating costs deliver affordable capacity for the USAF and partner nations. Its capabilities continue to evolve, capitalizing upon advancements made in computers, avionics systems, engines, and structural technologies. These advancements meet emerging warfighter requirements to combat current and evolving enemy threats. Funding described in this document provides upgrades to the F-16 platform necessary for the delivery of joint lethality in the coming decades. These computer processing and avionics upgrades are critical to a modernized architecture compatible with current open, agile, and digital concepts that will maintain platform viability into the 2040s. Force structure expected tail count will be reduced to 755 by the end of FY27 - 151 Pre-Block 30 (Avg. Age 36.8 years) / 604 Post-Block 40/42/50/52 (Avg. Age 32.7 years). Post-Block and Pre-Block F-16s have similar capabilities and are interoperable but require some independent modernization and sustainment of hardware, software, and training. The F-16 Foreign Military Sales (FMS) Program is one of the largest in DoD, providing assurance to 29 partners and growing. F-16 remains in production in South Carolina and additional nations continue to commit to new aircraft purchases through the FYDP and beyond. Aircraft procurement efforts include, but are not limited to, Modular Mission Computer (MMC) and Display Generator Upgrade, Service Life Extension Program (SLEP), Communications Suite Upgrade (CSU), Auto Ground Collision Avoidance System (AGCAS), Advanced Identified Friend or Foe (AIFF) Mode 5, M-Code, Secure Mission Data Systems (SMDS), Center Display Unit (CDU), Head Mounted Integrated Targeting (HMIT) system, Radio Frequency Capability (RFC), Heads-Up Display (HUD), Multi-functional Information Distribution System-Joint Tactical Radio System MIDS-JTRS, Active Electronically Scanned Array (AESA) Radars, and F-16 Training Systems. The F-16 Maintenance Training Device (MTD) simulators enable the USAF to exercise and train using the latest available F-16 Fighting Falcon capabilities available to all block configurations. Funding for AETC-MTD Trainers mod is budgeted in PE 0809731F. Funding for all other F-16 mods in this exhibit is budgeted in PE 0207133F. In accordance with Section 1815 of the FY 2008 National Defense Authorization Act (P.L. 110-181), this item is 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. Funds may be used to address Diminishing Manufacturing Sources (DMS) issues. The FY 2026 request for F-16 Modifications includes 448,116 thousand of discretionary and 50,000 thousand of mandatory (reconciliation) for a total of 498,116 thousand dollars. The mandatory funds support F-16 electronic warfare capabilities development. Further information for this reconciliation request is provided in Section 20007 (Air Superiority) of the reconciliation exhibit. The FY 2026 request was reduced by 2.833 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.

No Senate LDA lobbying filing in the tracked data mentions this program element by code or alias.
Oversight
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-16 Modifications. No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
