Going to be interesting to see whether FVL-M does end up with a Hawk-sized cabin, or whether a larger troop load-out is selected. Some of the preliminary studies point to something closer in weight to a Chinook. Let's see if it weathers mission creep better than JHL did.
Based on what was published, there was a requirement for 24" per seat width and at least 66" cabin height. If nothing changed, it would mean more a S-92 size cabin.
