Congress reauthorized SBIR/STTR on April 13, 2026 (S. 3971), with authority running through September 30, 2031. The Department of Defense published 115 SBIR topics on its DSIP portal the same day. The DOD SBIR 2026 reopening is real and already underway, but it is not a single switch flipping on. Each DOD component is reopening on its own schedule, with its own solicitation structure, award amounts, and entry rules.
This is a defense SBIR startup guide for 2026: it maps the DOD landscape component by component so you can decide which one to target first and exactly what to prepare before its window opens.
Is DOD SBIR reopening in 2026?
Yes. SBIR/STTR was reauthorized on April 13, 2026, after a roughly six-month lapse that ran from October 2025 to April 2026. During that lapse, agencies could not accept new SBIR proposals, which is why so many applications stalled. Authority now runs through September 30, 2031.
DOD moved fast. On the day reauthorization was signed, 115 DOD topics went live on the DSIP portal (the DoD SBIR/STTR Innovation Portal). Much of this DOD SBIR topic development happened during the 2026 lapse, so components had a backlog ready to publish. Individual components are now releasing solicitations on compressed, staggered timelines rather than all at once.
A note on staleness, because it matters for your planning. The single authoritative source for which DOD SBIR topics are open right now is DSIP itself. Web search results for DOD topic status are routinely stale by weeks or months. If you find a topic that looks open in a Google result but it is not on DSIP, treat it as closed. We have seen founders waste a week building toward a topic that closed two cycles ago.
DOD SBIR is not one program -- it's a dozen
Here is the reframe that saves founders the most time: "DOD SBIR" is shorthand for a dozen separate programs run by different components. AFWERX, the Army, the Navy, DARPA, the Defense Innovation Unit, SOCOM, the Defense Health Agency, the Missile Defense Agency, and others each run their own solicitations with different structures, cycles, and award ceilings.
One more structural fact that trips up first-time defense applicants: DOD SBIR is funded as a contract, not a grant. That changes your accounting and compliance burden compared to a civilian SBIR grant from NIH or NSF. You are a contractor delivering against a statement of work, with the reporting and cost-accounting expectations that come with it.
Here is the landscape at a glance.
| Component | What it funds | Structure | Phase I | Phase II | Cold-applicable? |
|---|---|---|---|---|---|
| AFWERX / SpaceWERX | Air Force, Space Force tech | Open Topic + Specific Topics | $50K-$250K | up to $1.5M | Open Topic is customer-gated; Specific Topics merit-reviewed |
| Army | Modernization-priority tech | Topic SBIR + xTech competitions | varies | up to ~$2M (xTech Accelerate) | Yes, topic SBIR is merit-reviewed |
| Navy / ONR | Fleet and Marine Corps needs | Topic SBIR + NavalX + ONR TechSolutions | varies | up to ~$1.5M | Yes, topic SBIR is merit-reviewed |
| DARPA | Breakthrough R&D | Office-wide BAAs (rolling) | varies | varies | Accepts cold, rarely converts without a sponsor |
| DIU | Mature dual-use products | Commercial Solutions Opening | $500K-$5M (prototype OT) | production OT | Accepts cold, needs an existing product |
| SOCOM | Special operations tech | SOFWERX + rolling BAAs | $50K-$500K | varies | Mixed |
| MDA | Missile defense tech | Topic SBIR | ~$150K | up to $1.5M | Yes, but often classified |
| IC (IARPA, NGA) | Intelligence research | BAAs, challenges | varies | $500K-$5M (IARPA) | High technical bar |
This table covers the highest-volume components. DHA (military health) and DLA (logistics) also run SBIR and are covered in the sections below.
The rest of this guide goes component by component, then covers the two gotchas that close most cold applications, and ends with a checklist of what to prepare now.
AFWERX and SpaceWERX (Air Force and Space Force)
AFWERX runs one of the largest SBIR programs in DOD by award volume. It has a two-track structure that founders consistently confuse, so be precise about which one you are pursuing.
Open Topic accepts proposals year-round (when SBIR is authorized) and lets you propose any Air Force-relevant technology. It is broad and less prescriptive. Specific Topics are tied to a defined problem and open only during set windows. The distinction matters because Open Topic carries a customer-memorandum requirement that Specific Topics often do not (more on that below).
AFWERX award sizing: Phase I is typically $50K to $250K, and Phase II goes up to roughly $1.5M. Watch afwerx.com and DSIP for new AFWERX SBIR solicitations in 2026, since Open Topic and Specific Topic windows are being announced on separate schedules. Beyond core SBIR, AFWERX runs Spark Collider events that match Air Force problem-owners with commercial solutions, and periodic Challenges tied to specific capability gaps. The Air Force Research Laboratory (AFRL) runs its own challenges with a deeper technical bar, often expecting PhD-level domain expertise.
SpaceWERX is the Space Force equivalent. Its flagship lines include Orbital Prime (on-orbit servicing, assembly, and debris remediation, $250K-$1.5M) and Tactically Responsive Space (rapid launch and small-satellite deployment). Both require credible space-operations capability, not just a ground demo.
What to prepare for AFWERX: a dual-use narrative that explains why the Air Force specifically needs your technology, and the start of an end-user relationship if you are eyeing Open Topic.
Army (topic SBIR plus the xTech competitions)
The Army runs standard topic SBIR tied to its six modernization priorities: Long Range Precision Fires, Next Generation Combat Vehicle, Future Vertical Lift, Network, Air and Missile Defense, and Soldier Lethality. If your technology does not map to one of those, your Army SBIR odds drop sharply.
The Army also runs the xTech family of prize competitions, which is a genuinely useful on-ramp for first-time defense applicants. xTech Search awards smaller prizes ($10K-$250K range) through a multi-phase pitch-and-prototype format and can lead to SBIR Phase I/II contracts. xTech Accelerate funds more mature prototypes up to roughly $2M. There are also focused variants like xTech LETHALITY (weapons and soldier-lethality tech) and xTech Global (which opens the competition to allied and partner nations alongside US companies).
Why this matters for cold applicants: a topic-driven Army Phase I is merit-reviewed. You are competing on the quality of your proposal against a published topic, not on whether you already know a program manager. For founders without existing DOD relationships, merit-reviewed topic SBIRs are usually the highest-probability entry point.
Navy and ONR
The Navy runs standard topic SBIR for Navy and Marine Corps needs, plus two adjacent mechanisms worth knowing.
Navy topic areas that map to this guide's audience include autonomous and unmanned maritime systems, AI and data analytics for fleet operations, cybersecurity, and undersea sensing. If your technology fits one of those, a Navy topic Phase I is merit-reviewed and worth a cold application, the same way an Army topic is.
NavalX runs challenges that connect fleet problems to commercial solutions. ONR Global TechSolutions is a rapid-prototyping program where Sailors and Marines submit operational problems and expect a working prototype in 12 to 18 months. TechSolutions rewards practical, fieldable solutions, not research projects.
One honest constraint: maritime environment requirements (shock, salt spray, vibration) raise the engineering bar. If your prototype has only been tested on a bench, budget for ruggedization before you promise a fieldable Navy deliverable.
DARPA and DIU: the relationship-gated track
DARPA and the Defense Innovation Unit are different animals from topic SBIR, and treating them the same is the most expensive mistake we see defense founders make.
If you are searching for "DARPA SBIR 2026," start with one fact: most DARPA money does not flow through standard SBIR topics at all. DARPA funds breakthrough R&D through office-wide Broad Agency Announcements (BAAs) that stay open on rolling 12-to-24-month cycles. The offices map to technology domains: BTO (biological technologies), DSO (defense sciences), I2O (information innovation), MTO (microsystems), STO (strategic), and TTO (tactical).
DARPA BAAs accept cold submissions, but they rarely convert without a program manager who already understands and wants your work. Proposers Days are where those relationships start. DARPA also runs the Embedded Entrepreneurship Initiative, a $250K stipend for entrepreneurs commercializing DARPA-funded technology.
DIU uses the Commercial Solutions Opening, an Other Transaction (OT) authority that moves faster than traditional contracting. Prototype awards run $500K to $5M, and a successful prototype can flow into a production OT without re-competing. The catch: DIU funds mature dual-use products, not basic R&D. You need an existing commercial product and the willingness to work on commercial timelines.
The honest read on both: a cold CSO or BAA submission is cheap to make and worth doing if the fit is strong, but treat it as a 6-to-12-month relationship-building exercise, not a near-term check. Many DIU prototype awards go to a small incumbent cohort that already holds the agency relationship. If you are competing cold against an established vendor, name that reality to yourself before you invest 80 hours in the proposal.
SOCOM, DHA, MDA, DLA, and the intelligence community
The DOD SBIR 2026 reopening reaches well past the headline components. A few more worth knowing:
- SOCOM runs SOFWERX (challenges and rapid prototyping in Tampa) and a standing FY23-FY28 BAA for biomedical and human performance technologies that accepts rolling submissions.
- DHA (Defense Health Agency) funds military health research, which aligns well with health-tech and medical-device founders.
- MDA (Missile Defense Agency) runs topic SBIR with Phase I around $150K and Phase II up to $1.5M. Expect classified topics and likely facility-clearance requirements.
- DLA (Defense Logistics Agency) funds supply-chain, warehouse-automation, predictive-maintenance, and additive-manufacturing technologies at enterprise scale.
- Intelligence community: IARPA funds high-risk research through BAAs ($500K-$5M) with an extremely high technical bar. NGA runs geospatial challenges. In-Q-Tel is a strategic investor that takes equity rather than awarding grants, so it is a different deal entirely. DHS Science and Technology, while not DOD, runs the Silicon Valley Innovation Program with up to $800K in milestone-based, non-dilutive funding for homeland-security tech.
The two gotchas that close most cold applications
Two structural gates quietly disqualify more first-time defense applicants than any technical weakness.
1. The Customer Memorandum (CusMemo) gate. Several Department of the Air Force programs, including AFWERX Open Topic, the Direct-to-Phase-II (D2P2) path, and most DAF topics, require a signed memorandum from an end user before you submit. Securing a CusMemo takes 2 to 6 months of relationship-building. If you do not have an active conversation with an Air Force or Space Force program manager or end user already in motion, a CusMemo-gated program is effectively closed to you in the near term, no matter how good your technology is. The Army and Navy have their own relationship realities, but they do not use the CusMemo instrument specifically, so do not assume every DOD topic requires one.
2. Cold CSO and BAA conversion. DIU CSOs and DARPA office-wide BAAs accept cold submissions but rarely fund them without a sponsoring program manager or portfolio manager. The submission cost is low, so it can be worth doing, but plan for a long relationship build rather than a quick win.
There is also a related trap worth naming. D2P2 looks attractive on paper at around $1.25M versus roughly $250K for a topic Phase I. But D2P2 is customer-gated. For a company without existing DOD customer relationships, a merit-reviewed topic Phase I is usually the higher-probability path, even though the headline number is smaller. Do not chase the bigger number into a gate you cannot clear.
Finally, watch the binary eligibility gates. These are pass/fail, not "mostly fine":
- Ownership: more than 50% must be owned and controlled by US individuals, with FOCI (foreign ownership, control, or influence) considerations.
- VCOC registration: venture-backed companies pursuing the majority-VC-ownership path must register as a venture-capital-operating-company structure where required.
- SAM.gov registration: you cannot receive an award without an active registration and a UEI.
- PI citizenship: some topics require US-citizen or permanent-resident principal investigators.
- ITAR: export-controlled work carries its own restrictions.
If any of these is uncertain for your company, resolve it before you write a word of the proposal.
Which DOD component should you target first?
The short rule: pursue a cold, merit-reviewed topic SBIR first, and run any relationship-gated programs in parallel as a 6-to-12-month build.
Beyond that, let your technology domain guide the component:
- Autonomy, robotics, ground systems: Army (topic SBIR or xTech), DARPA TTO, DIU.
- Space, on-orbit services, responsive launch: SpaceWERX.
- Cybersecurity: AFWERX, plus CYBERCOM innovation events and DARPA I2O.
- Biodefense, human performance, medical: DHA, SOCOM biomedical BAA, DARPA BTO.
- Dual-use AI/ML with a shipping product: DIU, AFWERX, IARPA.
- Sensors, microsystems, RF: DARPA MTO, Navy/ONR, AFRL.
If two components both fit, start with the one where you can find a published, merit-reviewed topic that matches your technology. That is the path you can pursue today without first spending months building a relationship.
What to prepare right now (before your window opens)
Whether your target component has already dropped topics or is still finalizing its 2026 schedule, these steps are worth doing now:
- Register on SAM.gov and get your UEI. This alone can take weeks and blocks any award. Do it first.
- Confirm your ownership posture. Verify the more-than-50%-US-individual-ownership requirement, address any FOCI issues, and sort out VCOC registration if you are majority VC-owned.
- Pick your component and 2-3 candidate topic areas. Map your technology to a specific modernization priority or office, not "defense generally."
- Start one end-user or program-manager conversation. If your target is CusMemo-gated, this is the long pole. Begin now.
- Draft your dual-use narrative. One page on why this specific component needs your technology and how it transitions to a program of record.
- Set DSIP alerts and check it weekly. DSIP is the authoritative source for open topics. Web search is not.
Do these six things and you will be ready to move within days of your component's solicitation opening, instead of starting the registration scramble after the clock is already running.
Mapping your DOD strategy
DOD SBIR is not one decision. It is a sequence of decisions across a dozen components, each with its own structure, timing, and gates. The founders who win their first defense award are usually the ones who picked the right component for their technology and prepared the registration and relationship work before the window opened.
If you are not sure which DOD component fits your technology, or whether you are competitive cold versus relationship-gated, that is the first question to answer before investing 40-plus hours in a proposal. Cada has mapped funding across 30+ agencies, including the DOD components above. We do a free defense grant roadmap assessment that tells you which components match your technology and how to sequence them into a multi-program strategy. No pitch, just a straight read on where you are competitive.
