LGM-35A Sentinel

LGM-35A Sentinel figures cover R-1 program element 0605238F and P-1 line 3020 Ground Based Strategic Deterrent. The exhibit titles say Ground Based Strategic Deterrent. They are included because the Air Force Global Strike Command fact sheet states that the LGM-35A Sentinel was originally called the Ground Based Strategic Deterrent, or GBSD. Parenthetical gross amounts and rows with no printed net are not included. Obligations are only the USAspending awards carrying reviewed DoD acquisition program code 493 (LGM-35A SENTINEL). Awards are not linked by a similar name. FY2027 enacted line amounts are not loaded: P.L. 119-103 states no program-line amount. 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.

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.
