I think what the author of "Mr Scott's Guide To The Enterprise" was getting at when he called the new ship the former USS Ti-Ho was that he meant perhaps the former USS Taiho, which was a WW2 Japanese carrier sunk in the Battle of the Philippine Sea. If he's on the BBS somewhere or someone knows where he is, we could ask him.
IIRC, it was a reference to a story by a friend of his. I tried to find the original interview where I read that, but it's not coming up.
In addition to ghost-ship Yorktown and new-build Ti-ho, FASA said it was a new-build originally named Atlantis.
