Contacts at the Air Force Research Laboratory (AFRL) has provided CBC with a flyer describing opportunities for undergraduates (and recent undergraduates) to get funding to work at or with AFRL. The flyer is linked here: AFRL Opportunities
The programs vary substantially: some are almost entirely managed externally, and some allow AFRL researchers to advocate heavily for specific collaborations. Each program has various requirements which are described in in detail with the links.
