Which Enterprise? (See Enterprise or Hornet thread for possiblities)
As far as online photos, you can try NavSource.com, and the Naval Historical Center has online images.
If you can get books, I recommend Bob Sumerall's Iowa Class Battleships, Dulin and Garski's US Battleships of WW2, and Paul Stillwells' Battleship New Jersey (I know, not the Missouri, but a damn good reference for general information and fittings), and Norman Friedmans' US Battleships Illustrated Design History. The ultimate reference is Floating DryDock USS MIssouri Plans book, which has everything you need.
(from the website) **Snip**This 11x17 inch, 120 page book covers the USS MISSOURI BB63 as she appeared on Sept., 2, 1945. With over 100 external drawings and over 120 photographs, every detail of the ship is shown. All weapons, radars, equipment, hull lines, and other details are explained and shown in both drawings and photographs. This book is a must for the model builder of this famous battleship. Price $43.95 plus $5.25 shipping. **End Snip**
For the Enterprise CV-6, Classic Warships Pictorials on the Yorktown Class, Stefan Terzibastich (sp) book on US Carriers in WW2, and Norman Friedmans' US Carriers Illustrated Design History.
For CVN-65, Bert Kinzey's USS Enterprise Detail in Scale is a must have.
Off the top of my head, that's all I have. I'm sure there's other stuff out there aside from the usual Squadron Signal books.
