DoW SBIR/STTR FY27 Release 1 Has 25 Topics and the Useful Window Closes October 27, Not November 25

The Department of War's FY27 SBIR/STTR Release 1 pre-released on October 7, 2026. It opens for submission on October 28 and closes November 25 at 12:00 p.m. ET. Twenty-five topics are on the table across four components.

Most firms will read that and mark November 25 on the calendar. That is the wrong date to be anxious about. The date that determines whether your proposal is competitive is October 27 — the last day of the pre-release window, and the last day you are permitted to speak directly to the person who wrote the topic.

Eleven days from today, the only real information advantage in the defense SBIR process closes, and the submission window opens the next morning into silence.

The release at a glance

Award ceilings: Phase I runs up to $300,000 for Air Force and Office of the Secretary of War topics and up to $315,000 for Navy topics. Direct to Phase II topics go up to $2,000,000.

Component split: 16 Air Force topics (13 SBIR, 3 STTR), 6 Navy, 2 Office of the Secretary of War, and 1 Army topic running on an xTech track with its own calendar.

This follows FY26 Release 6, which closed October 21 — DARPA's seven SBIR topics in that release were the last FY26 shot. The gap between the two closes is seven days. A firm that went all-in on Release 6 and lost has an immediate second at-bat, but only if it starts pre-release conversations this week rather than waiting for the Release 6 outcome.

The Air Force is buying maturation, not discovery

The most strategically informative fact in this release is the Air Force topic mix. Of 13 Air Force SBIR topics, seven are Direct to Phase II at $2 million each. All three Air Force STTR topics are also Direct to Phase II. That is 10 of 16 Air Force topics skipping Phase I entirely.

The D2P2 topics:

• DAF27BZ01-DV007 — Reusable Illumination System
• DAF27BZ01-DV008 — Technical Data Package Modernization
• DAF27BZ01-DV009 — Ultra-High Temperature Ceramic Polymers
• DAF27BZ01-DV010 — Low SWaP 2-Micron Fiber Amplifiers
• DAF27BZ01-DV011 — Robotic Wire Harness Installation for UAS
• DAF27BZ01-DV012 — Autonomous Technical Data Package to Robotic Path Planning
• DAF27BZ01-DV013 — Advanced Reserve Power Source Technologies
• DAF27TZ01-DV001 — AI-Enabled Air-to-Air Refueling Performance and Pilot Debrief
• DAF27TZ01-DV002 — Cyber Resiliency for Fog and Edge Computing
• DAF27TZ01-DV003 — Cooperative Perception for Uncrewed Air Systems

Direct to Phase II is not a shortcut. It requires you to document Phase I-equivalent prior work — feasibility already established, on your own dime or someone else's, with evidence a reviewer can evaluate. Firms routinely misread D2P2 as "the big one" and submit against it with a concept rather than a record. Those proposals are rejected on eligibility, not merit.

The flip side is that if you do have the prior work, the competitive field on a D2P2 topic is dramatically thinner than on a Phase I topic, because the eligibility bar screens out most of the field before scoring begins. Scan the ten topics above and ask a narrow question: have we already built and tested something that addresses this? If yes, this is the single best-value opportunity in the release.

The six Air Force Phase I topics cluster tightly around hypersonic and high-enthalpy test instrumentation — Shallow Jet Spurt Engineering Model, luminescence-based simultaneous pressure and temperature surface measurement, high-speed hyperspectral imaging for high-enthalpy testing — plus optical packaging (OPALS), multi-site telemetry synchronization, and a long rod delivery system. If you build test and measurement instrumentation for extreme environments, four of the six are addressable by one company.

Counter-UAS appears twice, which is a procurement signal

The Office of the Secretary of War contributed exactly two topics, and they are the same topic twice:

• OSW27BZ01-NV001 — Counter-UAS Rapid Maturation (Phase I, up to $300,000)
• OSW27BZ01-DV002 — Counter-UAS Rapid Maturation (Direct to Phase II, up to $2,000,000)

When the Secretary's own office spends its entire allocation on one problem and splits it into both an entry lane and a maturation lane, it is not running an experiment. It is building a pipeline and deliberately opening it to both firms with existing counter-drone hardware and firms with a new approach. The word "Rapid" in both titles is doing real work.

For small counter-UAS companies, note that the one-proposal-per-topic rule discussed below means you must choose between NV001 and DV002 strategically — they are separate topics, so submitting to both is permitted, but the resource question is whether you can field two credible proposals in a four-week window.

The rule change that breaks the shotgun strategy

Effective October 1, 2026, the Department of War limits proposals on a per-topic basis. The historical practice of submitting multiple variant proposals against a single attractive topic — different technical approaches, different teaming arrangements, hoping one lands — is over.

This changes the economics of the release for prolific submitters. Under the old regime, a firm with broad capability could blanket a topic and let the evaluators pick. Now, internal selection happens before submission, which means the quality gate moved inside your company. If you have two plausible approaches to DAF27BZ01-DV011, you now have to kill one yourself, and you should do it this week rather than at the end of November.

It also raises the value of the pre-release conversation proportionally. When you only get one shot per topic, finding out from the Technical Point of Contact which of your two approaches actually addresses the requirement is no longer a nicety. It is the difference between a funded proposal and a wasted cycle.

The Navy list is unstable — verify on the portal

The Navy contributed six topics: five conventional SBIR topics under DON27BZ01 plus one CSO open topic, DON27BX01-NP001, for low-cost heads-up displays for VR and AR.

But there is a discrepancy worth flagging. Third-party topic summaries list DON27BZ01-NV003 (Corrosion-Resistant Cargo Door Actuator) and DON27BZ01-NV005 (Intermediate Temperature Cooling Unit) as live, while the Navy's own topic listing marks both as REMOVED. Topics do get pulled during pre-release, and the authoritative source is the DoW SBIR/STTR Innovation Portal, not an aggregator.

The operational lesson generalizes beyond these two topics: re-verify every topic you are writing against on the official portal before the submission window opens, and again before you submit. A firm that began drafting on October 8 against a topic pulled on October 15 has burned three weeks. This is the same failure mode that makes aggregator-sourced award ranges unreliable across the grants world, and it is more consequential here because the drafting cost is higher.

The remaining Navy topics — a time domain reflectometer tank level indicator cleaner, a fire-resistant joiner bulkhead, and a secure input-output unit for hull, mechanical, electrical and navigation signal routing — are shipboard sustainment problems. They are unglamorous, which means fewer proposals and a real path for a firm with naval engineering credibility.

The Army topic is not on this calendar

ARM27BX01-DP001, Spectrum Enabled Warfare, is technically part of Release 1 but runs an entirely separate process. It routes through an xTech competition:

• White paper due October 23, 2026 at 5:00 p.m. ET — seven days from today
• DSIP proposals from finalists and winners due May 7, 2027

If spectrum warfare is your domain, stop reading and go write the white paper. The November 25 date is irrelevant to you, and the gate you actually have to clear is a week out. xTech white papers are short relative to a full SBIR proposal, which is both the opportunity and the trap — a short document with a hard deadline is exactly the kind of thing that gets deprioritized until it is too late.

What to do between now and October 27

1. Pick your topics today, not next week. You have eleven days of TPOC access remaining.
2. Contact the Technical Point of Contact for every topic you are seriously considering. This is the only window. After October 27, questions go unanswered and you are writing against the published text alone.
3. Audit your prior work against the ten D2P2 topics. If you have Phase I-equivalent evidence, that is where the leverage is.
4. Resolve internal duplicates now. One proposal per topic means you choose, and choosing late wastes engineering time.
5. Re-verify topic status on the DSIP portal before you invest drafting hours.
6. If spectrum warfare applies, the real deadline is October 23.
