'It does look familiar indeed. There is some of the 'form follows function' to that, and I also believe that the C-2 borrowed some design cues from the C-17 as well, didn't it?'
---when we discuss any military project in China, such as Y-20, we should always keep another thing in mind that is, you may use "borrow" the design from US, because countries like Japan and India....do have the access to matured US technology to intergrate to "their" own product, look at Japan's F-2---do we call it a copy to F-16? when we look at India's LCA
, from avitronics to engine, how much were really developed by itself? and we are openly "share"technology with these countries.
what about China? how much we can openly sell to China, or really, how much China can openly buy from us? then, if not, for a country as major as China is, would give up it's ambition to acquire some equiptment simply because somebody else has already inovated some concept proved to be successful? of course not, reverse engineering is certainly the result of many policies of our own.
when saying copy, honestly I don't think aircraft will be something easy to copied, it can only be copied or, reverse engineered by some country who itself has very solid tech and engineering capability, which China is certainly at the top of that group.
My whole point is, Y-20 seems to be a real success for chinese aircraft engineering, and we should all welcom it to the stage. With very limited access to the resource and support from the west, it's take off deserves a big congratulation.
