Most of ONR’s solicitations are for research and development and are accomplished through BAAs announcing research interests. BAAs are a streamlined method used to advertise and solicit performers for ONR research areas. A BAA or FOA is used to fill requirements for scientific study and experimentation directed toward advancing the state-of-the-art or increasing knowledge or understanding rather than focusing on a specific system or hardware solution. FOAs only result in the award of an assistance instrument and BAAs may result in the award of both acquisition and assistance instruments. BAA Calls are often released to focus attention on a specific topic and funding availability.
