SS Botany Bay Miniature
Web site by: Phil Broad

Identified as a DY-100 class interplanetary freighter, the "Botany Bay" (The Space Seed) would see service several times throughout the Star Trek series as other vessels including an "automated ore freighter" (The Ultimate Computer). Since Star Trek's senior Art Director, Matt Jefferies is a major fan of aviation (and a well known aviation artist) it is reasonable to assume that the "D" in DY-100 probably stood for "Douglas" as the Douglas Aircraft Company was one of the worlds largest aerospace contractors at the time and local to the LA area where Mr. Jefferies lives.  The Douglas influence was felt once again in the show with the appearance of the "Space Station K-7" (The Trouble with Tribbles) which is actually a line-for-line copy of a company proposal for a single payload (Saturn V) inflatable space station.  The studio simply took the design and "scaled it up" by adding lots of windows, thus making it appear to be several hundreds of feet in diameter rather than 100 feet in diameter.  This is the original studio miniature of the DY-100 as seen at one of the last "Equicon" science fiction conventions held in Los Angeles and is still in an unrestored condition.  It is mostly made of wood with a few model kit parts and some metal components.  The leading edge of the "sail" (a naval term for the tower structure found on most submarines) features a corrugated metal foil and the engine pod includes metal "antennas" and masts.  Judging by the details found on the model it is safe to assume that the actual spacecraft would have been capable of carrying two rows of the wedge shaped cargo pods seen here and they would continue right around the core structure when fully loaded.  The photographers scale seen in these photos is marked in inches.
