DoD Grant Submission Deadlines: Where They Are Published

DoD grant submission deadlines are not kept in one place. Each part of the department publishes its own: SBIR and STTR topics in the Defense SBIR/STTR Innovation Portal, CDMRP opportunities on Grants.gov with pre-applications in eBRAP, and ONR calls on its own site. Each one also sets its own clock time.

The dates quoted here come from FY2026 documents and show how the cycles work. Treat them as the pattern, and take the actual dates from the current topic page or announcement before you plan a submission.

Quick Answer: Where Are DoD Grant Submission Deadlines Published?

DoD SBIR and STTR close dates are published per topic in the Defense SBIR/STTR Innovation Portal (DSIP), where proposals go; FY2026 releases closed at 12:00 p.m. Eastern. CDMRP posts on Grants.gov and eBRAP; its FY26 cycle used 5:00 p.m. Eastern for pre-applications and 11:59 p.m. Eastern for full applications. ONR lists each call's cut-off time on its funding page.

Where DoD Grant Submission Deadlines Are Published

DoD grant submission deadlines are published by program, each in its own system. SBIR and STTR topics carry their close dates in DSIP, CDMRP opportunities are posted on Grants.gov and handled through eBRAP, and ONR posts calls on its website, SAM.gov and, where applicable, Grants.gov.

For SBIR and STTR the rule has no exceptions: "All DoW SBIR and STTR proposals must be submitted electronically through the Defense SBIR/STTR Innovation Portal (DSIP)," and "The DoW SBIR/STTR programs do NOT accept unsolicited proposals" (Defense SBIR/STTR, Funding Opportunities, read September 2026). A proposal sent anywhere else is not a DoD SBIR submission.

These are solicitations to buy research. DoD says it "uses the Broad Agency Announcement (BAA) funding mechanism to procure basic and applied research," and the Navy noted that awards under its CSO open topics "will use Other Transaction (OT) agreements" (Defense SBIR/STTR, Funding Opportunities, and Navy SBIR/STTR home page, read September 2026). The BAA or CSO a topic was released under is the document that governs it. ONR runs a long-range BAA alongside individual calls, and each call gives "the recommended dates for submission of proposals" (ONR, BAA N0001425SB001 Amendment 0006, posted January 14, 2026).

The pages use two names for the department. Under Executive Order 14347 (signed September 5, 2025), it may "be referred to as the Department of War" in non-statutory contexts, but "Statutory references to the Department of Defense ... shall remain controlling until changed subsequently by the law." The SBIR program pages use DoW, so search under both names when you look for a program's notices.

SBIR Grant Deadlines 2026: How DoD's Monthly Releases Worked

In fiscal year 2026, DoD released SBIR and STTR topics in monthly batches, each with its own pre-release, open and close dates (SAM.gov notice, DoW SBIR/STTR 2026 BAAs and CSOs, links updated April 13, 2026). The schedule published by the Defense Logistics Agency (DLA) shows the pattern; for current dates, check the topic in DSIP.

The governing notice said "DoW Services and Components may elect to release topics under this solicitation once a month," with new topics scheduled to "pre-release on the first Wednesday of each month," and "Each release will have corresponding open and close dates applicable only to those topics within the release" (SAM.gov notice, links updated April 13, 2026).

Source: Defense Logistics Agency, 2026 DoW SBIR/STTR Release Schedule (read September 2026), which notes "Dates are subject to change." Each topic's own page in DSIP holds the dates that apply to it.

From Release 2 on, each release opened three weeks after its pre-release and closed four weeks after opening (DLA schedule, read September 2026). The schedule also listed Release 5 evaluations on December 22, 2026 and awards on March 22, 2027, about six months after that release closed (DLA schedule, read September 2026).

The pre-release weeks are the time to ask questions. During pre-release "Small businesses are encouraged to communicate directly with topic authors," but once the BAA or CSO opens "direct communication between proposers and topic authors is no longer permitted," which leaves written questions through the DSIP Topic Q&A (Defense SBIR/STTR, Funding Opportunities, read September 2026). The same discipline as contacting a program officer before applying applies, with a hard stop on opening day. Topics released under Annual BAAs work differently: they "are published at least 45 days prior to the proposal submission deadline and have their own corresponding pre-release, open, and close dates" (Defense SBIR/STTR, Funding Opportunities, read September 2026).

The Small Business Innovation and Economic Security Act (P.L. 119-83), signed on April 13, 2026, reauthorized SBIR and STTR "through September 30, 2031" (Congressional Research Service, Insight IN12705, July 13, 2026). CRS adds that "Beginning in FY2027, the law requires that the director of a federal agency's SBIR or STTR program set a limit on the maximum number of proposals a small business can submit in response to Phase I and Phase II solicitations in a single fiscal year" (Congressional Research Service, Insight IN12705, July 13, 2026). Check the current solicitation for DoD's limit before planning several proposals, and see managing SBIR and STTR submissions and awards for what follows a submission.

CDMRP Deadlines: Pre-Application First, Then the Full Application

Every CDMRP opportunity has at least two deadlines, a pre-application in eBRAP and a later full application, and CDMRP states that "There are no grace periods for deadlines; failure to meet submission deadlines will result in application rejection" (CDMRP, How to Apply, updated July 2, 2026).

The pre-application is mandatory: "All CDMRP funding opportunities require submission of a pre-application in eBRAP" (CDMRP, How to Apply, updated July 2, 2026). It comes in two formats, a Letter of Intent or a Pre-Proposal. For LOIs "There is no review and selection process," while pre-proposals "undergo a review and selection process, and applicants will receive an 'invite' or 'not invite' decision for full application submission" (CDMRP, How to Apply, updated July 2, 2026). The format decides whether the full application deadline is yours at all.

FY26 deadlines show the two clock times CDMRP used (CDMRP program pages, read September 2026).

Source: CDMRP FY26 program pages and reference tables (read September 2026). PRMRP, CRRP and ORP used the same 11:59 p.m. Eastern full-application time in FY26, and in every case only organizations that had filed a pre-application could go on to the full application.

The full application goes through Grants.gov for extramural organizations, and "Proof of timely submission is automatically recorded by Grants.gov" with "An electronic date/time stamp" (eBRAP, General Application Instructions, FY26 version, read September 2026). The same instructions say "Grants.gov strongly recommends submitting the application package at least 24-48 hours prior to the close date to provide time to prevent technical issues from disrupting application submission" (eBRAP, General Application Instructions, FY26 version, read September 2026).

After the deadline, "applicants may not make changes to the Project Narrative and Budget attachments but can make changes to most other application materials until the end of the application verification period, typically a few days beyond the application submission deadline" (CDMRP, How to Apply, updated July 2, 2026).

The cycle is long. A 2016 National Academies evaluation described the CDMRP application review cycle as spanning "approximately 12 months, beginning with the annual congressional appropriation of funds," and noted that "Award negotiation and implementation may take an additional year" (National Academies of Sciences, Engineering, and Medicine, 2016). Read that timeline as the evaluation's description, not a current schedule; each year's program pages set the actual dates.

Clock Times for DoD Deadlines

DoD programs do not share one deadline time. DoD SBIR and STTR releases have closed at 12:00 p.m. Eastern, CDMRP's FY26 full applications at 11:59 p.m. Eastern, and ONR sets a cut-off time for each call.

The noon close shows up in the component listings: DARPA listed its FY2026 Release 5 topics as "Closes: Sept. 23, 2026 12:00 PM ET," and the Navy listed Release 6 as "Closes 10/21/26 (12:00pm ET)" (DARPA SBIR/STTR topics page and Navy SBIR/STTR home page, FY2026 releases, read September 2026). An earlier BAA spelled out what noon means: "Complete proposals must be certified and submitted in the Defense SBIR/STTR Innovation Portal (DSIP) no later than 12:00 PM ET," "Proposals submitted after 12:00 p.m. ET will not be evaluated," and "DoD is not responsible for missed proposal submission due to system latency" (DoD SBIR 2024 BAA, FY2024 cycle).

ONR's examples show why the call document matters: in September 2026 its funding page listed full proposals accepted "until: September 30, 2026 2:00 PM EST" for the long-range BAA and "August 31, 2026 4:00 PM EST" for another call (ONR, Current Funding Opportunities, read September 2026). By October 2026 the same page gave the long-range BAA "December 31, 2026 11:59 PM EST" (ONR, read October 2026). Copy the time with the date every time, and check it again before you submit. Deadlines around the September 30 end of the federal fiscal year have their own guide: federal grant deadlines at the fiscal year end.

Registrations to Finish Before a DoD Deadline

Finish registrations weeks before a DoD deadline, because DoD financial assistance needs a CAGE code on top of an active SAM.gov registration, and CDMRP estimates SAM.gov registration at "Several weeks based on required approvals" (CDMRP, How to Apply, updated July 2, 2026).

The Federal Service Desk's grant registration guide lists a CAGE or NCAGE code as required for entities that already have one and for entities seeking financial assistance from the Department of Defense (Federal Service Desk grant registration guide, read September 2026). CDMRP's estimates break the wait down: "10-15 business days to process a CAGE Code request or UEI renewal" and "5 weeks for a new or updated Taxpayer Identification Number" (CDMRP, How to Apply, updated July 2, 2026).

For the Grants.gov side, "Your organization must register with SAM.gov" and "You must have a Login.gov account" before starting (Grants.gov, Quick Start Guide for Applicants, read September 2026). Federal rules add that each applicant must "Maintain a current and active registration in SAM.gov at all times during which it has an active Federal award as a recipient or an application under consideration" (2 CFR 25.200(b), eCFR, current as of September 2026). The registration has to stay active after submission as well: if it is not current when the agency is ready to award, "the Federal agency may make a Federal award to another applicant" (2 CFR 25.205(b), eCFR, current as of September 2026). The guide to federal grants and Grants.gov walks through first-time registration, and our plain-English guide to 2 CFR 200 covers the federal rules that apply once an award arrives.

How to Track DoD Deadlines Through the Year

Track DoD deadlines at the source for each program: the topic page in DSIP for SBIR and STTR, Grants.gov notices and eBRAP for CDMRP, and the call documents for ONR. Put each close date on your calendar with its clock time and time zone.

Set up the official notices first. CDMRP says "Applicants should subscribe on Grants.gov to receive official notifications of new funding opportunity postings and updates," while "Email notifications of funding opportunities from eBRAP are sent as a courtesy," and it asks applicants to safelist "health.mil, eBRAP.org and Grants.gov" (eBRAP, General Application Instructions, FY26 version, read September 2026). Treat the courtesy email as a prompt to check the page, not as the record.

For SBIR and STTR, the FY2026 rhythm was monthly, so a monthly check of new pre-releases matched it. Record the pre-release, open and close dates for each topic you care about, plus the close time, and recheck the topic page before submission, since the schedule itself says "Dates are subject to change" (DLA, 2026 DoW SBIR/STTR Release Schedule, read September 2026). Do not assume the next fiscal year repeats the last; take each release's dates from DSIP.

Open-ended announcements need a cut-off date too. As amended on January 14, 2026, ONR's long-range BAA said it "will remain open for approximately two (2) years from the date of publication or until replaced by a successor BAA," yet ONR also stated that it "reserves the right not to review proposals submitted under this BAA after 30 September 2026" (ONR, BAA N0001425SB001 Amendment 0006, posted January 14, 2026). Even an open-ended BAA carries a date worth putting on the calendar, so read its latest amendment before you submit under it.

GrantCue's discovery search covers opportunities from Grants.gov, where CDMRP posts, along with state grant portals, foundations and community sources, and its NOFO summarizer lists key dates and deadlines extraction among its features (grantcue.com, September 2026). The Free plan includes 3 AI NOFO summaries a month and an ICS calendar feed for deadlines (grantcue.com, September 2026). The SBIR and startup solutions page covers GrantCue for small businesses applying to these programs.

FAQ

When Are DoD SBIR Deadlines in 2026?

In fiscal year 2026, DoD released SBIR and STTR topics in monthly batches, each with its own pre-release, open and close dates (SAM.gov notice, DoW SBIR/STTR 2026 BAAs and CSOs, links updated April 13, 2026). The Defense Logistics Agency's schedule listed six releases closing between June 3 and October 21, 2026, and component listings put each close at noon Eastern (DLA schedule and DARPA and Navy listings, read September 2026). Component and topic dates can differ, so take each topic's dates from DSIP.

Where Do You Submit a DoD SBIR Proposal?

Only in DSIP. DoD says "All DoW SBIR and STTR proposals must be submitted electronically through the Defense SBIR/STTR Innovation Portal (DSIP)," and "The DoW SBIR/STTR programs do NOT accept unsolicited proposals" (Defense SBIR/STTR, Funding Opportunities, read September 2026). A proposal has to answer a topic in an open release or an Annual BAA.

Does CDMRP Require a Pre-Application?

Yes. "All CDMRP funding opportunities require submission of a pre-application in eBRAP," as either a Letter of Intent, with "no review and selection process," or a Pre-Proposal, after which applicants "will receive an 'invite' or 'not invite' decision for full application submission" (CDMRP, How to Apply, updated July 2, 2026). "There are no grace periods for deadlines" at either step (CDMRP, How to Apply, updated July 2, 2026).

Can You Contact a DoD Topic Author Before Submitting?

Only during pre-release. DoD says that during pre-release "Small businesses are encouraged to communicate directly with topic authors," but once the BAA or CSO opens "direct communication between proposers and topic authors is no longer permitted," and questions go in writing through the DSIP Topic Q&A (Defense SBIR/STTR, Funding Opportunities, read September 2026).

Is the Department of War the Same as the Department of Defense?

Yes. Under Executive Order 14347 (signed September 5, 2025), the Department of Defense may "be referred to as the Department of War" in non-statutory contexts, while statutory references to the Department of Defense stay controlling until the law changes (Executive Order 14347, 90 FR 43893, September 10, 2025). SBIR program pages now say DoW, so search for notices under both names.

Check the Source Page Before Every DoD Deadline

Open the source page in the week you start work: the topic in DSIP for SBIR and STTR, the program page and Grants.gov listing for CDMRP, and the call document for ONR. Copy the close date and its clock time into your calendar, and note the pre-release window if you have questions for a topic author.

Then finish the registrations with the longest lead times first, beginning with the CAGE code and SAM.gov, and recheck the source page the week before submission. The published date is the one that counts, and on DoD SBIR releases it has meant noon Eastern.
