Since the days of the early sailing vessels and other similar expeditions on many planets, the naming of ships has been an important part of many races and cultures' histories.

The naming of ships was often held in high esteem, with the quality of a ship's name seen as a factor of a vessel's success. Lieutenant Piper of Proxima Beta once mused about the mistake of naming the USS Star Empire. She considered the name to be somewhat ignoble, preferring more virtuous names such as Majestic, Embassy, Valiant, and Ramage. (TOS - Fortunes of War novel: Dreadnought!)
