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 $69.3M for FY2024; the PB2026 book reported $69.3M as actual total obligation authority — $51.0K below the request. 69.29 − 69.34 = -0.05 USD millions — the compact figures above are rounded for reading.

Description
Description — Adversary
This line item funds the modifications to the Adversary aircraft and mission systems. The Adversary aircraft are a combination of 42 F-5 Tiger IIs (39 F-5Ns and 3 F-5Fs), the J85 Engine supporting the F-5, 14 Block 15 F-16 Fighting Falcon (10 F-16As and 4 F-16Bs), and the F-100 Engine supporting the F-16. The Adversary aircraft provide essential sorties in support of TOPGUN, Fleet Replacement Squadron, Carrier Strike Group, Carrier Air Wing and Unit Deployment Plan. Both the F-5s and the F-16s are planned to be used as primary Adversary mission through 2035. An additional 22 F-5s (16 F-5Es and 6 F-5Fs) were procured in 2020 from the Swiss government and will be upgraded to the USN/USMC NATOPS configuration. An additional 26 F-16s (20 Block 32 F-16Cs and 6 Block 25 F-16Ds) began transferring in April 2022 from the United States Air Force/Air National Guard. These aircraft will be upgraded to maintain common configuration with the USAF program. Adversary Missions Systems will provide peer threat replication and support future integration of Live, Virtual, and Constructive (LVC) capabilities.
Justification
Justification — Adversary
OSIP 011-21: Funds are requested in FY 2026 for the Air Vehicle modification of F-16A/B adversary aircraft which include legacy Falcon Structural Augmentation Roadmap (STAR) and additional structural modifications identified by the OEM. These upgrades will extend the service life of the current Adversary F-16 fleet from 4,250 flight hours to 8,000 equivalent flight hours through airframe strengthening and air vehicle upgrades required to maintain sufficient aircraft inventory to meet Fleet operational requirements. Funds requested in FY 2026 would be used to continue incorporation of the modifications into the F-16 aircraft. OSIP 003-22: Funds are requested in FY 2026 to continue to fund installation of production kits for the avionics and radar upgrades to maintain a common configuration with the USAF F-16 program. Installations will be performed as a depot or depot field team mod. OSIP 004-26: Funds are requested in FY 2026 to begin installs of A-Kits in Marine Corps Adversary Aircraft which will provide RedNet 2.0 (pilot situational awareness) and procure the first Nonembedded Aircraft Processing Systems to provide modeling/simulation of peer threat systems. The FY 2026 request was reduced by $0.072 million for civilian personnel to optimize the workforce in compliance with Executive Order 14210, "Implementing the President's Department of Government Efficiency Workforce Optimization Initiative."

Follow the dollar
No follow-the-dollar view — none of this program's high-confidence awards records a positive obligation at any place of performance (flows cover 312 of 1,938 programs). why coverage is partial? →

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
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 Adversary. No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
Program dossier
No research dossier for this program — dossiers cover 50 of 1,938 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
