Every allied Marine Corps with the exception of the S. Koreans (they license built AAVs) is in need of a replacement for the AAV.
Will our allies that have Marines be interested in the MPC?
I ask the question mainly looking at the Pacific. No matter how doubtful I am about the "partnership missions" there is no doubting that many nations like to operate US hardware. Considering the growth in Marine Forces in the Pacific this seems like a no brainer.
Whoever wins the MPC contest will have a leg up on the competition to modernize our allies amphibious armored forces. A relatively small vehicle buy by the USMC could turn out to be extremely valuable.
Note: BAE believes that the US Army might eventually buy an amphibious vehicle to complete its Pacific Pivot. I don't know what information they have they gives them that idea but the display of the SuperAV at Ft. Benning late last year didn't escape my notice.
