Deltek research analysts show DOD (Department of Defense) spending rising from $97.9 billion in FY22 to a projected $109 billion in FY26. Over five years, DLA grew 21% to $22.6 billion. U.S. Special Operations Command fell 37%.
Why It Matters : Contractors should track agency-level trends, not top-line totals, to guide FY27 capture planning and proposal timing.
The Department of Defense's Fourth Estate, the collection of defense agencies and field activities that sit outside the military services, including DISA, DLA, and U.S. Special Operations Command, is spending more money, moving it faster, and pointing it at a narrower set of priorities than it did five years ago.
In a recent webinar, Deltek Research Analyst Christian Thornton and Advisory Research Analyst Alex Rossino broke down the spending data, budget requests, and procurement shifts driving Fourth Estate strategy through FY 2027.

Inside the Fourth Estate
Sharpen your FY 2027 business development planning within the agencies of the Department of Defense/War’s Fourth Estate.
Below are some of the main questions around worth building into a long-range GovCon growth plan.
How much is the DOD Fourth Estate spending, and where is it headed?
Fourth Estate spending grew from $97.9 billion in FY22 to a projected $109 billion by the end of FY26, a steady climb rather than a spike. Total obligations across FY22 through FY26 reached $465 billion. The quarterly mix has shifted somewhat between Q1 and Q2 spending, but the year-over-year trajectory has stayed flat and upward, not volatile.
For FY27, the Fourth Estate discretionary budget request stands at $184 billion, with an additional $245 billion in mandatory supplemental funding pending congressional reconciliation. This is the "moving target" nature of FY27 planning: discretionary funding looks dependable, while the supplemental dollars depend on legislative timing that contractors can't control. Budgeting a pipeline against the discretionary number, and treating the supplemental as upside, is the more defensible planning approach.
Which DOD agencies are driving the growth, and which are pulling back?
The top five DOD buying organizations accounted for $207 billion in spending over five years, a 24% increase as a group. That growth wasn't evenly distributed, though:
- DLA (Defense Logistics Agency) posted the most consistent growth of the group, up 21% to $22.6 billion, and was one of three agencies, alongside DHA and OSD, leading FY26's strongest growth.
- U.S. Special Operations Command moved in the opposite direction, declining 37% over the same period.
The takeaway for business development teams: "Fourth Estate" isn't one market. Agency-level tracking, not top-line totals, is what should inform account planning and capture prioritization for FY27.
What are the DOD's top modernization priorities through FY27?
Three themes came up repeatedly in the budget data: autonomy, cybersecurity, and AI.
Autonomy investment is tied to future force design, with funding directed at platforms for surveillance, reconnaissance, and contested-space operations.
Cybersecurity includes Zero Trust implementation deadlines that are set for the end of FY27, and contractors who can't show mature cyber practices risk exclusion from the procurement pool outright. DISA's network consolidation effort, which aims to retire duplicate IT contracts in favor of managed services under DOD Net, is part of the same push.
AI is the largest single bet. The AI Arsenal Initiative is aimed at SCIF-accredited data centers and next-generation AI supercomputing capacity. Use cases might include operational decision support, demand planning, and targeting, areas where contractors with domain-specific AI implementation experience will have an edge.
How are small businesses doing in Fourth Estate contracting?
Small business market share in Fourth Estate contracts grew from 12.6% in FY22 to a peak of 19.7% in FY25, before easing slightly in FY26. Performance varied by socioeconomic category:
- Women-owned small businesses have consistently met or exceeded both prime and subcontracting goals, the most reliable performer in the data set.
- Small Disadvantaged Businesses (SDBs) exceeded prime contract goals but underperformed on subcontracting targets, a gap worth flagging for teaming strategy.
For small businesses building a Fourth Estate pipeline, the data suggests prime opportunities are currently more accessible than subcontracting slots in some categories.
What contract vehicles and opportunities are coming up in FY27 and FY28?
Several named procurements carry meaningful dollar value:
- DOD Information Analysis Center MAC, an ongoing $48 billion vehicle.
- Integrated Mission Technologies Optimization, $400 to $500 million, expected August 2027.
- Joint Special Operations Forces Readiness and Training Support, $242 million, expected April 2027.
- JWCC Unified Cloud Marketplace, multiple funding tiers running through FY28.
Established vehicles including GSA MAS, SOE TLS, and OASIS remain active as multi-year procurement paths. Roughly half of annual Fourth Estate contract spending lands in Q4, a detail that should shape proposal timing and staffing plans as much as the topline budget numbers do.
What should GovCons do now to properly kick off FY27?
Four planning priorities follow directly from the data:
- Track agency-level trends, not aggregate Fourth Estate totals. DLA's growth and SOCOM's decline sit inside the same budget category but point to opposite capture strategies.
- Treat Zero Trust compliance as a market-entry requirement. The FY27 deadline is fixed, so vendors that aren't there yet are working against a clock, not a preference.
- Build AI credibility around named use cases. Decision support, demand planning, and targeting are where the FY27 dollars are actually pointed, and proposal language should reflect that specificity.
- Plan proposal and staffing timing around Q4 concentration. With roughly half of annual spending obligated in the fourth quarter, capture and proposal teams should treat Q4 readiness as a year-round planning input, not a fourth-quarter scramble.
Fourth Estate spending is not slowing down, and where it's going is getting more specific. Contractors who match their positioning to the agency- and initiative-level data, rather than the top-line growth number, will have a clearer read on where FY27 and FY28 opportunities actually sit.
Numbers like these shift as budgets move through markup, reconciliation, and obligation, which is why this kind of analysis needs a team watching it in real time rather than a snapshot taken once a year. Deltek's research organization includes more than 150 analysts who track federal, state, local, and international opportunities as they develop, cross-referencing budget documents, procurement forecasts, and agency activity to flag shifts before they show up in a press release. That's a different and far more robust kind of coverage than any general AI search tool can offer.
