k.apland,
If you are intrested in WW2 era, your best bet for additional detail info on Essex class might be
http://www.shipmodels.info/mws_forum/viewtopic.php?f=46&t=4802&start=2060
You will see several posters who know the Essex class and have photo's to back up their statements.
Best bet try searching under "essex class hanger decks". Look for Intrepid at NavSource.org , and, of course, Modelwarships.com (http://www.shipmodels.info/mws_forum/viewtopic.php?f=46&t=4802&start=2060)
I had saved a few links of Essex class Hanger pictures. Luckily the linlks still work. These thumbnails will take you to the original Pics.
This last one is the Intrepid Hanger deck.
Keep digging. You will find more. Don't forget photo tours of some of the Museum Carriers. Intrepid also has a Museum site. That could be a great visit.

P.S. I recommend you start yor own thread on the Build. I'm sure there will be plenty of interest and help.
