! Bus
| align="left" | Bus, short for all ships in the [[EC]] series, is a name given due to the original variant's design. Originally from alpha, this term stuck around even after the new models were introduced. The EC-88 and 89 are also known as the "GovBus" or "Free Bus." The term is ''not'' a reference to the ship's performance, contrary to popular belief.
