As i recall, that plane is the Pancake from that shooting game called 1945. and also that's not a boat but an aircraft carrier.

An aircraft carrier is not a boat?

Its a ship, not a boat.

Actually, the Vought XF5U-1 was a real aircraft, not from just a game . . . . http://en.wikipedia.org/wiki/Vought_XF5U

The large, amidships superstructure makes it more like an amphib than a carrier...

Artist's comment:

とりあえず何で空母がこんな半分商船みたいな形してるのかってのは本編でのお楽しみということで。

"BTW, the reason why the carrier has shape that it seems to be a merchant ship appears in my doujinshi. Wait till Winter Comiket of this year."

Ships from that game are based off of Real WWII aircraft... just without all the lasers, meganukes, etc.

"MPS Admiral Serensen" is a fictional aircraft carrier of private military company Myorenji Gloval Security in alternative history.
It can be disguised as a container vessel.

This plane, "Flying Pancake II" is a fictional UAV based on XF5U.
