Obsolescence warning
This site stopped being routinely updated in mid-2025 since the upstream Navy NAVADMIN server has shifted to hosting NAVADMINs in PDF format instead of text.
If at some point I decide to go and scrape the PDFs too then this will resume tracking upstream NAVADMINs. But for now you should visit the Navy website to know for sure what's going on, these NAVADMINs are just archived for posterity.
