The following figures are derived from the FASA Ship Construction Manual, and are intended for use in creating detailed deck plans of vessels. All figures are suggested guidelines only, and are reflective of technology as of Star Trek II: The Wrath of Khan (2285).

For full details, see pages 34-40 of the Star Trek II: The Wrath of Khan Ship Construction Manual (FASA Corp. 1983), by David F. Tepool, Fantasimulations Associates. Though long out of print, this book is occasionally available on eBay.
