DAF Microreactor Pilot (Eielson AFB)

The FY2026 and FY2027 DoD R-1 and P-1 exhibits contain no line titled Eielson or microreactor. Requested, enacted, and announced-ceiling figures are empty. No published award title names this pilot. Navy R-1 0603570N Advanced Nuclear Power Systems is a different line and is not included.

Each column is a different measure and they are not added together. A request and an enacted amount for the same year sit side by side; the request is never rewritten when an enacted amount arrives. A blank state names why there is no amount; only a stated amount, including a stated $0, shows dollars.

Sources and Evidence0

No figures recorded yet.

Every figure keeps its document, date, page or table, original unit and a short excerpt. Superseded figures stay on record. Amounts are exact; compact figures round.

Linked Awards

No awards are linked to this program yet.

USAspending awards reviewed as belonging to this program, matched on the exact award key, never on a similar name. Some are linked only because the DoW acquisition program code reported on the award maps to this program; that code is the agency's own field and can be wrong, so those rows are labelled separately. Net obligations through Oct 6, 2026; later years are partial. The appropriation that paid for an award is not identified, so obligations are not compared with the enacted column.

Method

Four measures

Requested
What a budget request asked for. Not money Congress provided.
Enacted
What a law provided, or a spend plan's allocation of a law's lump sum.
Announced ceiling
The most a contract vehicle or agreement could be worth, as announced. Not spending.
Obligated
Net obligations on USAspending actions of the awards linked to the program. The funding account is not identified.

An announced ceiling is not spending

A contract vehicle's ceiling can go unused, and the ceilings of multiple-award vehicles overlap in purpose. DefDex lists each announced ceiling separately and does not add ceilings together or to requested, enacted or obligated dollars.

Figures come from the budget justification books, public laws and agency announcements named in the evidence table; where a source shows no amount the tracker says so rather than showing zero, and where DefDex has not yet checked a source it says that too. See the methodology for how federal obligations are counted.
