The Navy is looking to end the CH-46 while the Army is still
funding the CH-47. We will need to have a replacement for the
46/47 as we really do not have a heavy helo without them.

CH-46 is not a heavy-lift helo and is only slightly related to the -47.
(they came from the same company, and are both twin rotor designs. That's
about it.)


I'd argue with that - the CH-47A was originally the YCH-1B, which was
a derivative of the YCH-1A, which was the Vertol 107 (militarized into
the CH-46). I'd say there's more similarities than there are
differences. You can see at a glance that the designs are related,
and they both relate to their predecessor, the CH-21.
