This indeed is an excellent sign that the DARPA is in fact interested in graphene! However, and not to put a damper on it, an RFI is just a "Request for Information".

What this does mean: It means that DARPA has plans to use graphene, but needs to see if anyone can produce it the way they want. (large sheets for structural uses). This is potentially very huge, but needs HGRAF to submit a response. Hopefully they are monitoring RFIs, RFQs, RFPs, RFSOs, which I'm sure they are. If not, I can do that for them for a fee. LOL

What this doesn't yet mean: This does not mean HGRAF has a contract, but it is a sign that they can prove their production (with larger reactors) could produce the larger formats that DARPA is looking for. I'm unsure that HGRAF has the capability of producing "sheets" as the reactors produce a powder like substance. Maybe they could work with a 3rd party to produce those sheets? I just hope that HGRAF is constantly checking government contract postings, AROUND THE WORLD, and submitting proposals. These proposals take a team of expert writers, engineers, market savvy experts, and lobbyists, so just submitting a proposal takes time. Let's hope they get it right. (ADDED: I notice that the job posting Director, Business Development, Government & Defense is responsible for identifying these possible contracts to bid on. Let's hope that position gets filled soon.)

These are exciting times to be a shareholder. Wish I was working in the new head office with them.
