I actually heard (prolly BS) that the USMC didn’t want a chin gun, because they don’t want pilots going Rambo and getting into slugfests above hot LZs. The Osprey is too expensive, and we can’t use them like VN Hueys (5,000 lost!!!!!!). They should drop their troops off a brisk hike to the fighting. No chin gun will help convince pilots to stay back.....or so that theory went.
USAF tried that same theory with the F4........didn’t work.
Got to have the gun .......those guys ain’t gonna go gunner in something built by the lowest bidder. Usually the waist ginners covered the area a chin gun would in this rig today.
Hopefully we see one IMO.
Stay safe !
