Janus Program

Army R-1 program element 0604129A, titled Advanced Power Applications. The exhibit does not print the word Janus. The whole printed line is stored. FY2026 is the P.L. 119-21 spend plan (mandatory). FY2027 is the discretionary request. The FY2026 R-1 has no 0604129A line, so FY2026 requested is empty. FY2027 enacted line amounts are not loaded: P.L. 119-103 states no program-line amount. Navy R-1 0603570N Advanced Nuclear Power Systems is a different line and is not included. No published award title names the Army Janus program. Announced ceilings are 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.

Janus Program: USAspending awards linked by exact award key
Award	Recipient	Net obligations by fiscal year	Why it is linked
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.
