Eric Flint and I turned in the final manuscript for The Span of Empire at the end of September 2014. They originally told us it wouldn't get onto the schedule until mid-2017, but Eric convinced them to find an earlier slot. It still wasn't published until September 2016.
I'd guess -- as a reader rather than writer (other than small bits of fanfic) -- that Baen's probably rather more willing to move things around for RFC (especially for a mainline Honorverse book) than for others. I've read that back in the day Tor's turnaround for Jim Rigney (better known as Robert Jordan) was much faster than it was for anyone else (sometimes to the books' detriment; some of the middle books in the Wheel of Time clearly needed more editing).
