DoD cancels $135M+ in Air Force SBIR topics, dealing a blow to early-stage defense tech founders
Apr 15, 2025
Key Points
- The Department of Defense canceled all Air Force topics from its Small Business Innovation Research solicitation, eliminating $135 million in initial awards and roughly $200 million in follow-on funding for early-stage defense startups.
- The DoD SBIR office announced the removal via email on April 15th, just before the second major cyber topics release of 2025 was set to accept proposals, giving founders minimal notice to adjust planning.
- SBIR grants are a critical early-stage funding mechanism for defense tech companies to validate product-market fit before pursuing larger contracts, making the Air Force cancellation a material blow to the defense startup pipeline.
Summary
The Department of Defense has canceled all Air Force topics from the current Small Business Innovation Research (SBIR) solicitation batch, eliminating approximately $135 million in initial awards and potentially another $200 million in follow-on awards that would have funded early-stage defense tech companies.
The DoD SBIR office announced the removal via email around 1 p.m. on April 15th, just before the second major cyber topics release of 2025 was set to begin accepting proposals. The solicitation's two primary agencies were the Navy and Air Force. The Air Force topics have been stripped entirely.
SBIR grants provide critical early-stage capital for defense startups to prove demand and validate initial product-market fit before pursuing larger program-of-record contracts. The Air Force cancellation represents a material blow to the defense tech pipeline.
Adam Wollinsky, formerly at Anduril, Nvidia, and Yale and now at Fid Labs, flagged the cancellation and provided context. Four major cyber topics releases occur per year, and this one would have been the second of 2025. The timing—just before proposals were due to open—gives founders minimal notice to adjust planning.
The cancellation appears tied to broader reform of the SBIR process and changes to DoD acquisition procedures. The underlying rationale has not been specified.
