A New H-6K Unit From Air 36 Division
One can only assume. I would imagine all naval h6g will get replaced, so that's some 30 planes. Plus we are now at over 60k models for air Force. At a minimum we are looking at some 90 airframes, though it could go to 120 if all older h6 are replaced 1:1. Since next gen bomber won't be produced for at least another five years, 120 seems likely if they don't want a production hiatus.
