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 $164.6M for FY2024; the PB2026 book reported $157.3M as actual total obligation authority — $7.28M below the request. 157.3 − 164.6 = -7.3 USD millions — the compact figures above are rounded for reading.

Description
Description — E-6 Series
This line item funds modifications to the E-6 Mercury aircraft to improve mission capability and readiness. All sixteen (16) aircraft, unless otherwise noted, in the E-6 fleet will receive each modification. The E-6 is a manned airborne communications platform designed to provide a survivable, endurable, and reliable airborne Command, and Control, and Communications capability in support of the President, Secretary of Defense, and United States strategic and non-strategic forces. -Safety Deficiencies (OSIP 008-02) corrects high risk aircraft safety hazards to protect personnel and equipment enabling mission readiness. -Tech Insertion (OSIP 003-04) corrects aircraft obsolescence, supportability, weight management and interoperability deficiencies through new technology insertion enabling mission readiness and mandate compliance. -Service Life Extension Program (OSIP 003-07) extends the service life of the aircraft to 2038+ through airframe strengthening and structural data recording and analysis. -Communications Upgrade (OSIP 012-07) installs expanded aircraft digital communication paths and processing to improve airborne command post operations and modernizes direct over-the-horizon communications links to deployed strategic forces. -Multi-Role Tactical Common Data Link (OSIP 013-10) installs expanded aircraft communication bandwidth capability required to interoperate with United States Strategic Command's National Command and Control Architecture. -Auxiliary Power Unit (APU) (OSIP 002-12) corrects airborne command post operational test deficiencies by installing an improved APU to meet increased aircraft power requirements. -Family of Advanced Beyond-Line-of-Sight Terminals/Presidential and National Voice Conferencing (FAB-T/PNVC) (OSIP 014-14) replaces obsolete Military Strategic Tactical Relay terminals with improved FAB-T and replaces Secure Emergency Conferencing Network with PNVC. -Mission Systems (OSIP 014-21) addresses obsolescence and supportability upgrades through technology insertion of commercial and government off the shelf (COTs/GOTs) systems.
Justification
Justification — E-6 Series
The FY 2026 funding request is for critical safety, readiness, obsolescence, avionics, and mission system modifications for the E-6B aircraft. The FY 2026 request was reduced by $2.610 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
Appropriation → program element → top high-confidence awards → recipient families → congressional districts.
Follow-the-dollar covers 312 of 1,938 programs — only high-confidence budget→award links are shown. why coverage is partial? →
The diagram illustrates the cited table below — amounts shown in the diagram are transaction sums per award (no citation chips); the per-district obligations in the table cite USAspending queries.
Related awards
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.

Contractor concentration
High-confidence award links only, pooled across ingested years. The index uses positive obligations; program obligations are net of deobligations. The figures over every published link, including medium-confidence ones, are in the downloadable warehouse, not on this page — why.
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 E-6 Series. 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? →
