How the Defense Budget Actually Gets Made
Most service members think the NDAA is the budget. It isn't. It's authorization — permission to spend money that a completely separate set of committees may or may not actually provide. Understanding the two-track system, the 30-month cycle, and what a Continuing Resolution actually does to your unit is the foundation for everything else in defense budget literacy.

Section 01
The Two Tracks: Authorization vs. Appropriation
This is the most important thing to understand. Two separate committees, two separate bills, two entirely different powers. Most people conflate them — including many people who should know better.
Authorization Track — NDAA
Who: Armed Services Committees
Senate Armed Services Committee (SASC) & House Armed Services Committee (HASC)
- —Sets policy: what DoD is allowed to do, what programs can exist, what authorities are granted
- —Sets authorized spending levels: the ceiling for what can be appropriated
- —Does NOT actually provide money — authorizes the possibility of spending
- —The NDAA has passed every year since FY1962 (over 60 consecutive years)
- —A program authorized in the NDAA but not appropriated is legally permitted but unfunded
Appropriation Track — The Actual Money
Who: Appropriations Committees
HAC-D (House) & SAC-D (Senate) — Defense Subcommittees
- —Provides actual budget authority — the money DoD can obligate and spend
- —Organized into 6 major defense accounts (MILPERS, O&M, Procurement, RDT&E, MILCON, Family Housing)
- —Can appropriate at different levels than authorized — often does
- —Failure to enact results in a Continuing Resolution, not suspension of the NDAA
- —Often fails to pass on time — leading to CRs that are now more the norm than the exception
The Six Major Defense Appropriation Accounts
Military Personnel (MILPERS)
CR Impact: LowPay, allowances, retirement contributions, and related compensation for active duty, reserve, and National Guard personnel. The most politically protected appropriation — pay rarely gets cut by CRs.
Operation and Maintenance (O&M)
CR Impact: HighDay-to-day operations, training, base operations support (BOS), depot maintenance, and contract services. The largest discretionary account and the one most affected by continuing resolutions in practice.
Procurement
CR Impact: HighBuying weapons systems, vehicles, aircraft, ships, and equipment — the hardware of the force. New production buys freeze under a CR; multi-year contracts continue at prior-year quantities.
Research, Development, Test & Evaluation (RDT&E)
CR Impact: HighDeveloping new systems from concept to production readiness. Early-stage programs are particularly vulnerable — they cannot begin if they weren't funded in the prior year's budget.
Military Construction (MILCON)
CR Impact: CriticalBuilding and renovating physical infrastructure — barracks, maintenance facilities, runways, training ranges. All construction projects freeze under a CR; no new contracts, no new starts.
Family Housing
CR Impact: ModerateDoD-operated family housing programs, including construction, operations, and maintenance. Managed largely through privatized housing partnerships; CR impacts depend on contract structure.
Section 02
The Timeline: 30 Months from Start to Money
The budget cycle for any given fiscal year begins roughly 18 months before that year even starts. By the time Congress votes on an NDAA, the programming decisions behind it are already 12–16 months old.
OMB Issues Passback Guidance
The Office of Management and Budget gives DoD its spending targets and policy priorities for the upcoming budget request. This is the opening gun of the budget cycle — DoD components learn their toplines before they have formally submitted anything.
Program Objective Memoranda (POM)
Each military service and defense agency submits its Program Objective Memorandum — the five-year spending plan that forms the backbone of the Future Years Defense Program (FYDP). This is where services fight for their programs and priorities.
DoD Builds the FYDP
DoD leadership reviews POMs, adjudicates competing priorities, and assembles the Future Years Defense Program — the five-year plan that will be submitted to OMB and eventually Congress. The FYDP is the real budget; the single-year request is its first slice.
DoD Submits to OMB for Review
The President's Budget request is submitted to OMB for final scrubbing, policy review, and top-down reconciliation against spending targets. OMB can and does override service priorities.
President's Budget Request to Congress
The formal Budget Request is submitted to Congress. This is the starting point for congressional action — not a binding document, but the administration's stated priorities and the baseline for hearings and markup.
Armed Services Committees: Hearings & NDAA Markup
SASC and HASC hold hearings with service secretaries, Chiefs of Staff, and combatant commanders. Both committees then hold markup sessions — the line-by-line review where they authorize, modify, or reject programs in the NDAA. Remember: this authorizes, it does not appropriate.
Appropriations Defense Subcommittees: Hearings & Markup
HAC-D (House) and SAC-D (Senate) hold their own hearings and markups on the defense appropriations bills. These committees actually provide the money. Their markup sessions are where specific dollar amounts are set for each program in each account.
Floor Votes & Conference Committees
Full House and Senate floor votes on both NDAA and appropriations bills. Conference committees reconcile House and Senate differences — this is where most of the real final decisions happen, often in staff-level negotiations that most members never read in full.
New Fiscal Year Begins
If everything goes on schedule, the budget is enacted. In practice, it almost never is. DoD typically begins the new fiscal year under a Continuing Resolution while Congress continues negotiations.
Section 03
The Continuing Resolution: What It Actually Does to Your Unit
A CR is not a budget. It is a funding patch. And its restrictions are more operationally consequential than its funding levels.
What a CR Specifically Prohibits
CR Impact by Function
Training Exercises
High ImpactO&M funding continues at prior-year rate under a CR, but new contracts for ranges, training events, and contracted support cannot be started. An exercise that requires a new contract vehicle — a new range booking, a new contracted support arrangement — cannot be executed. Exercises that were already contracted and funded in the prior year typically continue.
Equipment Procurement
High ImpactNew production buys freeze. If your unit was scheduled to receive a new equipment lot in Q1, that contract cannot be awarded under a CR if it's a new start. Multi-year production contracts continue at prior-year quantities. A 3-month CR at the start of a fiscal year can push equipment deliveries 6–12 months into the future due to cascading contract delays downstream.
MILCON: Facilities and Barracks
Critical ImpactAll MILCON projects freeze under a CR. No new construction contracts, no new project starts. If a barracks renovation or a new maintenance facility was funded in the President's Budget but the CR arrives before contracts are awarded, the project stalls until the budget is enacted. This directly affects quality of life timelines.
PCS and Personnel
Low ImpactMILPERS funding — pay and allowances — continues essentially uninterrupted under a CR. PCS orders are executed. Pay and BAH are not affected. This is the most politically protected account; Congress has never withheld MILPERS funding under a CR.
Base Support Services
ModerateContract services for base operations — facilities maintenance, grounds, some security contracts — may be affected if annual service contracts expired at the end of the prior fiscal year and new contracts were not yet awarded. The specifics depend on how each installation's contracts are structured. Annual contracts that cross fiscal years are in a better position than single-fiscal-year contracts.
Section 04
The Congressional Power Points
Authorization vs. Appropriation — Two Different Fights
Armed Services Committees and Appropriations Committees are different bodies with different power. HASC and SASC authorize what DoD is allowed to do. HAC-D and SAC-D actually provide the money. A program can survive NDAA markup and die in appropriations markup — or be authorized at $500M and appropriated at $400M. Understanding which committee killed a program tells you a lot about whose priorities prevailed.
Conference Reports: Where Final Decisions Actually Happen
The conference report — the document reconciling House and Senate versions of the NDAA or appropriations bill — is where most real final decisions are made. Conference negotiations are conducted largely by staff, with limited member involvement. The conference report is often filed and voted on within days, giving members little time to read it. This is where programs are saved or killed without floor debate.
CR Anomalies: How Individual Needs Get Accommodated
During a CR, Congress can pass specific funding exceptions called "anomalies." These grant targeted permission to spend above prior-year rates or to start a new program during the CR period. Obtaining an anomaly requires individual political effort — working with the Appropriations Committee to include it in the CR text. Commands with better congressional relationships are better positioned to get anomalies that protect critical programs during CR periods.
Earmarks and CDS: The Directed Layer
Congressionally Directed Spending (CDS) — the modern form of earmarks — sits on top of the base budget. Members of Armed Services and Appropriations Committees can direct funds to specific projects at specific installations in their states. These additions can fund projects the administration didn't request, and they survive regardless of how the overall budget fight goes. See the full earmarks analysis for details.
Section 05
What This Means for Service Members
When your unit's training event gets canceled in October or November with no clear explanation, the reason is often a CR. The O&M contract that would have funded the range, the contracted range support, or the training area cannot be started under a new-starts prohibition — even if the money notionally exists.
When new equipment arrives months later than projected, the reason is often that a CR-era new-start prohibition delayed the contract award by a quarter, which cascaded through the production schedule. A 90-day CR at the start of a fiscal year can translate to a 6–9 month delivery delay on equipment that takes 18 months to manufacture.
When your barracks renovation doesn't start when the timeline said it would, the reason is often that MILCON new starts are frozen. A project authorized in the NDAA and funded in appropriations cannot break ground until the budget is enacted — and if that takes until December or February, you lose construction season in many climates.
Your pay and allowances continue regardless. But much of what determines the quality of your daily service life — training, equipment, facilities — runs on O&M and MILCON timelines that are highly sensitive to whether Congress can pass a budget on time. In recent years, it usually cannot.
Frequently Asked Questions
What is the difference between the NDAA and the defense appropriations bill?
The NDAA (National Defense Authorization Act) is passed by the Armed Services Committees. It authorizes what DoD is allowed to do and sets authorized spending levels — but does not actually provide money. The defense appropriations bills, passed by the Appropriations Committees, actually provide the funding. A program can be authorized in the NDAA and never appropriated — it's legally permitted to spend money it doesn't have. In practice, both bills pass through conference and are usually aligned, but the distinction matters: authorization without appropriation is permission without funds.
What is a Continuing Resolution and how does it differ from a full-year budget?
A Continuing Resolution (CR) funds the government at the prior year's rate — or a specified rate — for a limited period, typically 30 to 90 days. Sometimes Congress passes a "full-year CR" covering the entire fiscal year at prior-year levels. Unlike a full-year budget, a CR prohibits "new starts" — new programs, new production contracts, or new construction projects that weren't funded in the prior year. This is the key operational impact: not that funding is dramatically cut, but that new activity cannot begin until the CR expires or a full-year budget is enacted.
What is the Future Years Defense Program (FYDP) and why does it matter?
The FYDP is the five-year spending plan that DoD submits to Congress alongside the annual budget request. It shows planned funding levels for every major program across the next five fiscal years. The FYDP is the real planning document — the single-year request is the first year of the FYDP. Changes to programs in the out-years of the FYDP signal where DoD is actually going, even if the current-year numbers look similar. When a program is deleted from the FYDP, it is effectively dead even if its current-year funding hasn't been touched yet.
Has the NDAA passed every year? Could Congress simply not pass it?
The NDAA has passed every year since FY1962 — over 60 consecutive years. It is considered must-pass legislation because it authorizes pay raises, sets military policy, and authorizes the legal basis for DoD's major activities. While technically Congress could fail to pass an NDAA, it hasn't happened in modern history. Appropriations, however, have routinely failed to pass on time — which is why CRs are so common. DoD can operate without a timely appropriation (under a CR); operating without any NDAA authorization would be a more fundamental breakdown.
What is a Program Objective Memorandum (POM)?
A POM is each military service's five-year spending plan submitted to DoD leadership during the internal budget process. Services use the POM cycle to fight for their priorities before the President's Budget is assembled. Programs that don't make it into the POM typically don't make it into the budget request — meaning they would need to be added by Congress. The POM process is largely internal to DoD and not publicly disclosed in detail, but the results are visible in the President's Budget request.
What does "above-threshold reprogramming" mean and why does it matter?
During execution — after the budget is enacted — DoD can move money between accounts to respond to changing needs. "Reprogramming" moves money within an account; "transfers" move money between accounts. Moves above certain dollar thresholds require congressional approval (above-threshold reprogramming). This process allows DoD to respond to emergencies like unexpected operational costs, but it also requires building relationships with the Appropriations Committees. When DoD needs to reprogram funds for a developing operation, committee approval is the gating factor.
