I think some funding was identified for Sikorsky to look at a possible AMCM mission / Navy heavy lift mission for this new helo. It has been high on the MH-53E OAG (operational advisory group) "top ten" for the last 2 years. I don't recall on where (or if) it broke out on the All Helo top ten requirements list.
With program costs totalling over $20k per flight hour (MH-53) the bean counters seem to want to divest and look at other programs/platforms that could possibly do the mission (to some standard...maybe the good enough standard).
Who knows, though. The current airframes are being extended and there is a move afoot to get glass cockpits. Someone is looking out for Navy heavy lift.
We'll enjoy the airframe while we have it.
