Small Business Innovation Research (SBIR) Small Business Technology Transfer (STTR)

Solicitation Schedule

The Department of Defense issues three SBIR and two STTR solicitations for proposals annually. Each solicitation has a: pre-release, open and close. During the pre-release period the government is not accepting proposals, but small businesses can discuss technical questions directly with the topic authors (contact information available in each topic). Once the solicitation is open, direct questions with the topic authors are no longer allowed, but technical questions may be submitted anonymously through the SBIR Interactive Topic Information System (SITIS)External Link.

A list of other Federal Government SBIR solicitations is available at SBIR.gov.
