I apologize for comming in so late, to your discussion. But, I've got some info, for you.
There are plans for USS Gaum (LPH-9) at this web site: <<http://www.floatingdrydock.com/>>
Goto the Warships section, click on the "G" series and page down. There's a set of Guam drawings, 1:192 scale, for $30 (circa Sept 85). It might be what you're looking for. The part # is G-LPH9. If you have questions, call Tom. He listes his phone number and is a great guy to work with.
As far as this trip down memory lane, I know what you're talking about. I served on ten ships, during my career. The last one was commissioned in the early 70s. She retired from the Navy the day before I retired, '97. She, and one other, are up in Washington state, awaiting disposal. The sail of another is a Submarine memorial in Brazil. All the others have long since become razorblades.
A truely sad ending for some truely great ladies.
Mike
