Agency Guides
The DoD SBIR guide: the biggest buyer, decoded.
Updated July 28, 2026 · Free educational guide · verify details at the official sources linked below
DoD is the largest SBIR agency (over $2B/year), awarding contracts through the DSIP portal. In 2026 topics pre-release the first Wednesday of each month; the pre-release window is your only chance to talk directly to the topic author. Phase I awards typically run $100K–$250K; AFWERX Direct-to-Phase-II goes up to ~$2M with a signed customer memo.
The 2026 rhythm: monthly releases
Historically DoD ran three big BAA cycles a year. After the April 2026 reauthorization it shifted to monthly releases: topics pre-release on the first Wednesday of the month, then open for proposals a few weeks later, then close about a month after that. Whether the old three-cycle rhythm returns in FY2027 hasn't been announced — watch DSIP.
The single most valuable window is pre-release. Before a topic opens, you may contact the Topic Point of Contact (TPOC) — the government engineer who wrote it — directly. Once it opens, direct conversation ends and only the public Q&A remains. Founders who call TPOCs during pre-release learn what the topic is really asking for; founders who don't, guess.
The components have personalities
- AFWERX (Air Force) / SpaceWERX (Space Force): the commercial-friendly front door. Open topics let you pitch your own dual-use technology. Its Direct-to-Phase-II (up to ~$2M, up to 21 months) requires a signed Customer Memorandum from a Department of the Air Force end-user — without it your proposal isn't evaluated. That memo is a networking task, not a paperwork task: it's why the events calendar matters.
- Navy: the most traditional. Structured topics, a base-plus-option Phase I (recently ~$140K base + $100K option), and a strong expectation that you understand the acquisition program your tech would feed.
- Army: leans on xTech prize competitions — pitch, win cash, and get invited into SBIR — plus larger vehicles like CATALYST for prioritized technologies.
- DARPA: a different animal: Direct-to-Phase-II-heavy, no recurring topics, and proposals must argue a step-change, not an increment.
If your project needs simulation
DoD topics are dense with simulation language — aerothermal analysis, structural margins, RF co-site, thermal management. Reviewers expect modeling in the work plan, and winners usually show some of it in the proposal itself. If that's the gap in your plan, ask us about Ansys evaluation options and an engineer to help you scope the study.

Mechanics that trip up first-timers
- Registration chain: SAM.gov → SBIR.gov company registry → DSIP. Start at least 8 weeks out; SAM alone can take 2–6 weeks. Full walkthrough: the registration checklist.
- Contracts, not grants: you'll invoice for milestones. Budget for a bookkeeper who has seen government contracts.
- Foreign-ties disclosures are now mandatory and rigorously screened — sloppy answers are disqualifying.
- Phase III is the prize: a successful DoD SBIR line gives the government the right to buy from you sole-source, and your data rights are protected for 20 years. That's the leverage that gets primes to partner instead of clone.
