The DY-500 was a class of early Earth space vehicles. (TOS reference: Spaceflight Chronology)
Service history and disposition[]
Schematic on a cargo manifest, accessed in 2364.
The DY-100 class received extensive design and performance reviews to become the DY-500 class. Its almost pure fission engine plant produced a clean gas exhaust who powered a MHD, providing electricity to the ship. At the moment of its commission it was one of the most popular transports. The loss of the DY-500, UNSS Courageous, was the worst tragedy in the first 65 years of space exploration. (TOS reference: Spaceflight Chronology)
An uprated DY-500, circa 2049.
The DY-500 and DY-100 were similar enough in appearance that even experienced Starfleet officers were unable to tell the difference between such ships from a distance. For example, upon first encountering the SS Botany Bay, Captain James T. Kirk initially believed the ship to be a DY-500, it was Spock who correctly identified the ship as an older DY-100 type vessel. (TOS episode: "Space Seed")
In 2155, two DY-500s were involved in the First Battle of Altair VI when they attempted to intercept a Romulan fighter, but were called off by the Columbia. (ENT - The Romulan War novel: Beneath the Raptor's Wing)
The SS Malaspina was a DY-500 class transport in service to United Earth's Merchant Marines in the 22nd century. Malaspina was scrapped in 2169. (Decipher RPG module: Starships)
The Mariposa in 2123.
The Heart of the Storm was an alleged DY-500 active in the 2240s. (TOS novel: Prime Directive)
