The Defense Intelligence Agency (DIA) is reopening its flagship Solutions for Intelligence Analysis (SIA 3) contract vehicle through a new Small-Business On-Ramp—a rare chance for qualified small firms to join a $17 billion program that supports the Defense Intelligence Analysis Program (DIAP) worldwide.
With the RFP expected in January 2026 and awards projected by fall, firms that prepare now will have a decisive advantage. Once the on-ramp closes, new entrants may wait years for another opening.

Why This Matters
The SIA program gives DIA and the Combatant Commands access to rapid, integrated, all-source intelligence analysis—everything from crisis response to long-term strategic forecasting.
This on-ramp competition will determine which small-business contractors join the pool to provide analytic support for the next decade. Tasks may include:
- National-level and theater intelligence analysis
- Intelligence planning and management support
- Support to deployed forces and rapid response missions
- Intelligence training and program integration
Because DIA only opens on-ramps intermittently, missing this one could mean no access to SIA-task orders for years. Firms that start preparing now can:
- Validate domain alignment under NAICS 541990
- Build or formalize teaming agreements for coverage and reach
- Organize past performance packages that demonstrate analytic depth
- Develop a compliant management and technical framework early
