Why is Army Aviation trying to cram themselves aboard ship?

Question.  Why is Army Aviation trying to cram themselves aboard ship?

Is it doctrine based?  I don't think so.  I can't find any OPEN SOURCE documents that detail a need identified by the Navy or Marine Corps that is fulfilled by putting Army Aviation aboard ship.  Additionally I'm not even sure that Army Aviation meets basic NAVAIR safety guidelines for operation on ships.  Remember the modifications that were deemed necessary, just on the safety and maintenance side to make the Apache, NAVAIR worthy of becoming the Sea Apache?

So if its not doctrine based.  If its not safe or doesn't meet NAVAIR guidelines then what behind this move?

I'm not sure.  I can make a guess though.

The Army is desparate.  They're trying to find a way to make themselves relevant in the Pacific and see themselves getting left on the beach looking slack eyed and silly.

Its really a shame though.  The Army does have a role to play, a supporting role...and if the conflict is big enough, a combat role but it isn't by flying off individual ships and doing photo ops.

If the Army wants to be relevant in the Pacific then they need to push HARD to make the Sea Base a reality, doing the dull and boring work with Military Sealift Command integrating their landing craft and CH-47's with the MLP and Maritime Prepositioned Squadrons, and work out how they're going to operate to make that system fit the needs of forces ashore.  Working to develop the means to ferry soldiers to the Sea Base so that they can marry up with their equipment.  Training their soldiers on LCAC operations.

But no.  They instead push Army Aviation onto already crowded ships.  Amazing.
