not so near future anymore I'd say something like his will exite in the next 2 years if that if when I saw in the US navy magozines when I left back in 07, this picture looks very similar to the new DX class destroyer ship type will all the new goodies including the stealth skin like the F-122 raptor has. it was in production last I heard.
It has too be the mix of sexy mecha boats with the beautiful ocean and its colors.
Hope to see more futuristic ship and tanks later in time.
Good luck with your art.
