The Research (R&D) Grants program directly funds research overseas. International Program Officers (IPOs) at AFOSR international field offices work closely with Program Officers (POs) at AFOSR Arlington, to fund basic research in of interest to the AFRL mission, across a wide spectrum of technical areas. Proposals in response to the AFOSR Broad Agency Announcement (BAA) are accepted year-round and evaluated by AFOSR Program Officers and Air Force researchers. Grants may be single or multi-year, and grants may be for stand-alone research, or may supplement existing research efforts.
