If they're using it in prod then there are plenty of regulations that should force them to establish a real support relationship.
Sometimes this type of stuff happens for a prototype that an org is trying to get funded, but not for 10 years. I'd collect all of the org email addresses they used for the initial d/ls and contact them first- maybe one of the ones from ten years ago has gotten promoted to a point where they can establish a paid relationship or approve use of the open source version.
I believe the Cold War names mostly came from US contractors- the government defined requirements ("air superiority fighter") and the contractors came up with designs that then had to be marketed against each other so they were given cool names ("Fighting Falcon").
Now there has been a lot of consolidation of contractors, and budgets are much more constrained. You no longer have the DoD funding competing designs and selecting, but a situation closer to early WW2 where the government is closer to the design.
At least that's my 5 minute guess, probably lots of 'citation needed' to be done.
