BAE just put out the above video and supposedly there is suppose to be an industry day later this week. Additionally HQMC is putting out a bit more information on how the upgraded AAV and MPC will work together (like how they're going to have to increase the size of the AAV battalions).
It all points to politicking for Dunford to continue the MPC/ACV 1.1 project. I'm not sure he'll be swayed.
It all depends on that 900 pound gorilla in the room, the F-35. If it turns out to be as cheap as we're being told...AND...its maintenance costs aren't back breaking then maybe (but I seriously doubt it). Additionally the CH-53K flies in December and is going to gobble up funds soon too.
My guess? The AAV will continue for another 20 years. Just a reminder of what we were told. Check out the vid below...
