Broad Agency Announcement
What it actually means
A standing solicitation for research proposals against broadly stated interests rather than a fixed specification — the government describes problems, proposers describe approaches. It's the front door for most defense science-and-technology funding, and unlike an RFP, submissions are evaluated on scientific merit rather than head-to-head against each other.
Where you'll meet it
DARPA, service labs, and R&D program offices; where most early-stage defense research money enters.
