Military construction budgets show how federal building resources are distributed among service branches, locations, project types, and housing programs. The figures below cover fiscal years 2024 and 2025 and are reported in thousands of dollars. They come from the FY 2025 Green Book, the FY 2025 C-1 budget book, and the June 2025 FY 2026 C-1 book; the source label is kept with each group because the books use different budget measures and publication points.

FY 2025 authorization and TOA
The FY 2025 Green Book lists $15,235,094 thousand in requested total Military Construction authorization and $15,561,215 thousand in total Military Construction TOA. TOA is the total obligation authority measure reported by the budget book. These totals describe the overall Military Construction account and should not be treated as a location-only total or as a count of individual projects.
The same source reports several major program totals. Military Construction, Army had $1,915,300 thousand requested and $2,311,157 thousand in authorization, budget authority, and TOA. Military Construction, Navy and Marine Corps had $2,953,119 thousand requested and $4,540,899 thousand in authorization, budget authority, and TOA. Military Construction, Air Force had $5,409,814 thousand requested and $3,187,126 thousand in authorization, budget authority, and TOA.
Military Construction, Defense-Wide had $3,329,026 thousand requested and $3,733,163 thousand in authorization, budget authority, and TOA. The NATO Security Investment Program had $433,864 thousand in authorization, budget authority, and TOA. These figures are program-level budget measures from the FY 2025 Green Book, not independent estimates of construction spending in Guam.
The FY 2025 Green Book also identifies reserve and guard construction accounts. Military Construction, Army National Guard had $291,600 thousand requested and $362,129 thousand in authorization, budget authority, and TOA. Army Reserve had $220,000 thousand requested and $255,032 thousand in authorization, budget authority, and TOA. Navy Reserve had $26,610 thousand requested and $29,829 thousand in authorization, budget authority, and TOA.
Air National Guard had $139,800 thousand requested and $190,792 thousand in authorization, budget authority, and TOA. Air Force Reserve had $68,000 thousand requested and $69,263 thousand in authorization, budget authority, and TOA. The accounts distinguish national guard and reserve construction from the principal Army, Navy and Marine Corps, Air Force, and Defense-Wide programs.
Service and reserve components
The June 2025 FY 2026 C-1 book presents another FY 2025 view, with different requested and TOA figures for several accounts. Because this is a later budget-book presentation, it is best read as a separate reported snapshot rather than silently combined with the FY 2025 Green Book.
| FY 2025 account | Requested ($ thousand) | TOA ($ thousand) |
|---|---|---|
| Army | 1,924,800 | 2,236,357 |
| Army National Guard | 275,100 | 419,489 |
| Army Reserve | 220,000 | 295,032 |
| Navy and Marine Corps | 6,840,715 | 5,286,680 |
| Navy Reserve | 26,610 | 29,829 |
| Air Force | 5,657,814 | 3,834,426 |
| Air National Guard | 199,700 | 290,492 |
| Air Force Reserve | 46,000 | 74,663 |
| Defense-Wide | 2,107,951 | 3,881,383 |
Source: FY 2026 C-1, June 2025 book. The source reports $293,434 thousand for the NATO Security Investment Program in authorization, appropriation, and TOA. The table should not be used to infer a simple year-over-year change from the FY 2025 Green Book, because the source book and reported budget presentation differ.
The FY 2025 Green Book separately lists Base Closure Account amounts: $212,556 thousand for Army, $111,697 thousand for Navy, $121,952 thousand for Air Force, and $1,756 thousand for Defense-Wide. These are identified as authorization, budget authority, and TOA. They are distinct from the principal Military Construction service accounts.
Family housing budgets
Family housing is reported separately from the main Military Construction program. In the FY 2025 C-1, Army family housing construction was $245,314 thousand in authorization and $276,647 thousand in appropriation/TOA. Within that amount, Army family housing new construction was $164,200 thousand and construction improvements were $81,114 thousand. Army family housing operation and maintenance was $485,611 thousand.
Navy and Marine Corps family housing construction was $232,413 thousand in authorization and $273,141 thousand in appropriation/TOA. New construction accounted for $196,975 thousand, while construction improvements accounted for $35,438 thousand. Navy and Marine Corps family housing operation and maintenance was $489,385 thousand.
Air Force family housing construction was $214,992 thousand in authorization and $221,549 thousand in appropriation/TOA. The FY 2025 C-1 reports $336,250 thousand for Air Force family housing operation and maintenance. Defense-Wide family housing operation and maintenance was $52,156 thousand.
Two improvement funds were also reported. The Department of Defense Family Housing Improvement Fund had $6,611 thousand in authorization/appropriation and $6,442 thousand in TOA after the undistributed adjustment. The Military Unaccompanied Housing Improvement Fund had $496 thousand in authorization/appropriation and $494 thousand in TOA after the undistributed adjustment.
The June 2025 FY 2026 C-1 repeats the FY 2025 Army family housing construction figures as $245,314 thousand requested and $276,647 thousand TOA. It also repeats Army family housing operation and maintenance at $485,611 thousand. Those repeated values remain tied to that later book’s presentation and are not additional construction funding.
Construction by location
The March 2024 budget book identified $19,000,000 thousand in FY 2025 total military construction by location in TOA. Of that reported location grouping, construction inside the United States was $8,811,136 thousand, construction outside the United States was $3,324,972 thousand, and construction at unspecified locations was $4,538,836 thousand.
The explicit “outside the United States” category is the location grouping most relevant to readers assessing overseas construction, but it does not identify Guam separately. The supplied figures therefore support an overseas total, not a Guam-specific total. The unspecified-location amount should remain separate because the source does not assign it to a geography.
These location figures also illustrate why a total military construction number needs a definition. A budget total may be organized by service, account, purpose, or location, and the same budget book may present several related groupings. The three location categories above are TOA figures from the FY 2025 C-1 rather than a project count, parcel count, or forecast of local construction activity.
Construction by purpose
The March 2024 FY 2025 C-1 reports several purpose categories in TOA. Major construction totaled $11,972,448 thousand. Unspecified minor construction totaled $372,445 thousand, while planning and design totaled $1,706,692 thousand.
Other reported purpose amounts were $382,378 thousand for new construction, $387,022 thousand for construction improvements, $566,970 thousand for operating expenses, $224,033 thousand for leasing, and $323,507 thousand for maintenance. Base realignment and closure totaled $389,174 thousand.
These categories should be read as the source presents them. “Planning and design” is not the same activity as completed construction, and leasing, maintenance, and operating expenses are not interchangeable with new construction. The figures are useful for describing the composition of the reported budget, but they do not establish how many buildings were completed or how much work occurred during the fiscal year.
FY 2024 comparison
The FY 2025 Green Book reports FY 2024 total military construction at $11,061,313 thousand requested, $16,676,582 thousand in appropriation, $16,674,944 thousand in budget authority, and $19,000,000 thousand in TOA. The multiple measures show why requested funds, enacted or appropriated amounts, budget authority, and TOA should not be collapsed into one figure.
For FY 2024, Army military construction was $1,703,286 thousand requested, $2,760,475 thousand in appropriation, $2,758,837 thousand in budget authority, and $3,955,232 thousand in TOA. Navy military construction was $5,499,777 thousand requested, $6,550,013 thousand in appropriation, $6,548,375 thousand in budget authority, and $7,614,334 thousand in TOA.
Air Force military construction was $2,950,074 thousand requested, $4,629,013 thousand in appropriation, $4,629,013 thousand in budget authority, and $4,646,603 thousand in TOA. Defense-Wide military construction was $3,407,433 thousand requested, $3,602,339 thousand in appropriation, $3,602,339 thousand in budget authority, and $3,072,631 thousand in TOA.
| FY 2024 account | Requested ($ thousand) | Appropriation ($ thousand) | BA ($ thousand) | TOA ($ thousand) |
|---|---|---|---|---|
| Total military construction | 11,061,313 | 16,676,582 | 16,674,944 | 19,000,000 |
| Army | 1,703,286 | 2,760,475 | 2,758,837 | 3,955,232 |
| Navy | 5,499,777 | 6,550,013 | 6,548,375 | 7,614,334 |
| Air Force | 2,950,074 | 4,629,013 | 4,629,013 | 4,646,603 |

Source: FY 2025 Green Book. The same source reports FY 2024 purpose amounts of $9,996,327 thousand for major construction, $372,445 thousand for unspecified minor construction, and $1,706,692 thousand for planning and design. By location, it reports $8,811,136 thousand inside the United States, $3,324,972 thousand outside the United States, and $4,538,836 thousand at unspecified locations.
For Guam and other island communities, the central limitation is geographic specificity: the supplied budget figures identify an overseas category but do not quantify Guam’s individual share. They nevertheless provide a clear reference frame for reading military construction budgets—separating service accounts, housing, purpose, location, and the particular budget measure used.
